The Specification of ERW Steel Pipe

Some consumers haven't a awfully clear construct concerning of the definition, manufacture processing and application of ERW steel pipe. Today, Prime steel pipe can provide specification of ERW pipe in details for all of you.

The definition of ERW pipe


ERW pipe (also known as ERW steel pipe) is that the abbreviation resistance Welded Pipes. resistance fastening refers to a bunch of fastening method (including spot and seam fastening) that turn out conglutination of faying surfaces wherever heat to create the weld is generated by the ohmic resistance of fabric combined with the time and therefore the force accustomed hold the materials along throughout welding. ERW steel pipes and tube are available in various qualities, wall thicknesses, and diameters of the finished pipes.

ERW tube manufacturing process


ERW steel pipe is manufactured by rolling metal and then welding it longitudinally across its length. ERW steel pipes are welded longitudinally, manufactured from Strip / Coil and can be manufactured up to 24”OD. ERW pipe cold formed from a ribbon of steel pulled through a series of rollers and formed into a tube which is fused through a electric charge.
Typical ERW tube manufacturing process of Prime Steel Pipe generally involves the following stages in a step by step procedure.

ERW steel pipe’s application


ERW steel pipes are used in various engineering purposes, fencing, scaffolding, line pipes etc. It is available in lengths from single random to 120 feet depending on mill capability. What's more, ERW steel pipes are usually used for Agricultural purposes, Drinking Water for housings, in collieries for extraction of Water, Thermal Powers, Transports, Hand pumps for deep boring wells, as a powerful protection for cables by telecommunication Department, Structural functions etc. ERW steel pipe is obtainable with sq. ends or beveled for fastening, rib and matched and victaulic grooved. Surface end of it's on the market in black or vacant, or with protecting coatings.
Prime Steel Pipe have a awfully massive production capability of ERW steel pipes, in order that we are able to manufacture ERW pipes and tubes of various size and form supported the purchasers necessities.

Chinese economy with stand "look back"

People usually like to set a goal at start of the year,than look back to which goal was reached or which was not.In the past 2016,how about China’s expected goals?Can they stand the test of “look back”?Shinestar Steel Research Institute thinks the answer is yes according to the latest data.
In general,macroeconomic policy should focus on four goals at the same time:economic growth,full employment,price stability and international balance of payments.Accordingly,the government work report in 2016 said the main target in this year is:gross domestic product growth of 6.5% - 7%,consumer prices rose 3%,more than 10 million new jobs in cities and towns,basic balance of international payments.
According to economic growth, gross domestic product in 2016 GDP growth of 6.7% year-on-year, not only in line with expectations, and across the two mark: at one is success across 70 trillion yuan, 74.4 trillion yuan;The other one is after 2014 to us $2014, past the $11 trillion mark again this time.In addition, according to the international monetary fund estimates that India's economic growth rate in 2016 was 6.6%, lower than China.But a year ago, China's GDP growth by 6.9%, India is as high as 7.6%.This means that China's economic growth has been the first to return to the world's major economies.This "first", it is under the big idea of structure adjustment, quality priority, made the task well.
In employment ways,the new jobs in cities and towns of up to 12.49 million people in the first 11 months of 2016, the year 13 million new basic no suspense.The goal of building a town more than 10 million new jobs were not only finished ahead of schedule, and overfulfilled.In prices, consumer prices rose 2% in all the year round, full compliance with the start of "or 3% or so" target;As for the balance of payments, national safe has given the conclusion that overall improvement in cross-border capital flows, flow pressure eased, outside the main investment in China has been a net outflow from into a net.
In addition to the four major goals to finish well, the Chinese economy transcripts of many "bright eye".For example, the "three to one drop one fill results" preliminary revealed, accelerate industrial structure optimization of transformation, the new kinetic energy is more rapid growth, strategic emerging industrial added value growth of a large piece of higher than GDP growth.Shinestar group as submerged arc weld spiral welded pipe, seamless steel pipe, stainless steel tube, scaffolding, galvanized pipe and other products production services vendors, has always been positive response national policy, the future will also be going all out, to transformation and upgrading, promote the competitiveness of the enterprise.
Chinese meet difficult toil under pressure for a year, has brought the Chinese economy withstand "look back" report card.Step by step, has not come easily.Thankfully, this accomplishment this transcript is worth us to have a good collection.Shinestar group will continue to produce more and better the submerged arc weld spiral welded pipe, seamless steel pipe, ERW Steel Pipe, scaffolding, galvanized pipe and other products, for China's economic take-off added "new wing".

China's Program will Inject New Impetus into Globalization

Since 2016, the global economy is generally stable, but downturn situation has not fundamentally changed. Hunan Shinestar Steel Research Institute said that 2017 global economy will remain low growth and low recovery trend, "reverse globalization" wave of China's economic globalization program inject new impetus. As a manufacture of seamless steel pipe, OCTG, spiral welded pipe, stainless steel pipe,  galvanized pipe and other products, Shinestar Group will continue to pay attention to the world economy and China's economic development trends.

World economy needs to strengthen global economic governance, but the British off the EU referendum and Trump put forward the "US priority", which made regionalization to split and lost in globalization. In Europe, the US strategy is shrinking. In this context, new forces are needed, and new programs are leading global governance to a new stage. China is the world's second largest economy, China's economic development can not be separated from the world, the world's economy also needs China.

From the financial, trade, investment the three areas, by the effect of new president of the United States and the dollar interest rate and other factors, the global financial market will remain volatile and uncertainty in the short term, especially in emerging market countries will have to face the risk of currency devaluation and Capital outflow. At the same time, world trade still lack of powerful support, which make slow growth. Although the rebound of commodity prices or will bring some demand, but the magnitude is limited, global trade growth rate will remain lower than the economic growth. Global investment will be stronger due to USD raised, new trade protectionism and other factors, the recovery process is blocked. However, the rise of the fourth global industrial transfer, may lead to rebound in global investment. In addition, the Hangzhou G20 summit strong impetus to the global efficient financial governance which is good for developing countries and  inject new momentum for global economic growth.

The report notes that during the cyclical transformation of the world economy, China's five major development concepts will not only lead China's economic development, but also will lead the world economy into a new long-term positive kinetic energy. Globalization is at a crossroads in the transformation and incubation of the new cycle of the world economy. "One to one," the building tactics not only for the global economy out of the crisis haze, to realize powerful recovery and sustainable development provides new ideas, but also against the trend of globalization to promote economic globalization has injected new impetus and vitality.


In the future, Shinestar Group will take the opportunity to meet the challenges, and strive to develop themselves to produce more high-quality spiral submerged arc welded pipe, ERW steel pipe, stainless steel pipe, scaffolding, galvanized pipe and other products to develop China's economic.

Talking About The Risk of Economic Growth in 2017

At present China economy is slow in stabilization, steady for the better.Supply side structural reforms achieved interim results.The positive factors of economic growth  are increasing, but the structural contradictions and risks of economic development still exist.As the SSAW steel pipe,welded carbon steel pipe ,stainless steel pipe,and  other products manufacturers service,Shinestar group has been very concerned about the development of Chinese economy.Today, shinestar Steel Research Institute talk  about the risk of economic growth in 2017.
First, the risk of external shocks.  The global economy is facing increasing conflict, after the international financial crisis, the developed countries in Europe and the  United States have been mired in structural problems, economic reform is sluggish, slow economic recovery, conservatism tends to rise.Global economic growth is  expected to be generally weak, developed economies are still slow growth, emerging markets and the development of the economy will only moderate growth.U.S.  inflation is expected to push up interest rates and the dollar exchange rate,the new president of the United States proposed to reduce income tax, expand the scale of  infrastructure, repatriation of immigrants and other policies tend to push up U.S.Emerging market countries economic recovery is not solid, accompanied by domestic risk  is intensifying,especially continue to rely on credit to drive economic growth eventually leads to increased risk of damaging adjustment.
Second is the real economy from the bottom of the recovery, the economy is still downward pressure.In 2016, the real economy from the bottom of the recovery,Mainly  rely on supply side reform is expected to promote the recovery of PPI from the bottom, the real estate market driven by the growth of real estate investment growth  picked up.At present, the fixed asset investment growth downward pressure, has not yet appeared signs of cyclical rebound in fixed asset investment.Private fixed asset  investment growth continued to fall, real estate development investment growth may slow down.
Third is the real estate market than expected development potential risks.2016 real estate market than expected development of stable economic growth has played a  positive role, but its negative impact in 2017 need to be concerned.The real estate market regulation will have a negative impact on investment and bank profitability  indicators.2016 in October, some cities have adopted a more stringent measures to regulate real estate, real estate investment may also be down accordingly.At the end  of June 2016, commercial banks non-performing loans 1 trillion and 437 billion yuan, more than the same period last year 31%.Although the proportion of non-performing  loans of commercial banks is only 1.75%, but the proportion of non-performing loans and non-performing loans rising trend both need to remain vigilant.
Four is the pressure of capital outflows and devaluation is expected to rise. Since 2016 halfyear, China's foreign exchange reserves continued to decline significantly.  From January to November of 2016, the foreign exchange reserves accumulated decreased by 278.76 billion USD, the foreign exchange reserves of 3.05 trillion USD to the  end of November.After CNY joined the SDR, the CNY against the USD accelerated depreciation, as to December 29, 2016, has exceeded 6.95 CNY/ USD. Next year, IMF  will do more rigorous evaluation to CNY exchange rate control measure, which will make CNY capital control more difficult.
Shinestar Group will face marketing risk and challenges, and will make great efforts to produce more high quality ERW Steel Pipe,galvanized steel pipe ,stainless  steel pipe accelerate enterprise transformation and upgrading, and develop China's economic.

Reduce the burden of enterprise: the way of reform is the fundamental

Reduce the burden of enterprise: the way of reform is the fundamental
China's fiscal science research institute, said at the annual meeting of the strategy of social science college of finance and economics to solve the existing problems of enterprise comprehensive heavy burden not only rely on lower taxes, must want to promote all aspects of system reform, Shinestar of iron and steel research institute agree with it. Cost just rely on existing lower taxes, such as tax cut, cut, such as social security contributions appropriate to these as phased measures can be, however, may not rely on lower taxes to make the enterprise profit.
Enterprises in market competition to make money, in fact, depends on two aspects: one is the ability to create value. Second is the ability of cost control. At present, enterprise, industry and the economy as a whole are in a critical period of transformation and upgrading, climbing a camp, the firm's ability to create value is not strong, in the process of operating profit is thin. Shinestar group always pay attention to the innovation and development, continue to produce more technology content of Angle steel, galvanized Angle steel, channel steel, galvanized channel steel and other products, to further improve enterprise value. At this stage of development, on the other hand, some costs rise faster, such as artificial cost, environmental cost, etc. These costs rise is a sign of economic progress, but if the enterprise is unable to digest, will squeeze profit margins. Therefore, the enterprise profit space narrowing, actually is the result of the overall costs. To solve the problems of the current enterprise burden, is not just a question of tax burden, but comprehensive burden problem.
Some experts believe that the current public opinion excessively focused on the issue of taxes, it is one-sided. Comparing to traditional industries and emerging industries, emerging industries profit space is large, the existing taxes won't feel heavier; The traditional industry overcapacity, market is bad, in this case the heavier the cost will be back, so he wants the government to cut taxes. The government should give support to the traditional industry. However, tax reduction space is limited, more difficult is the issue of how to reform.
On the one hand, through reform and make the enterprise have a better business environment, reduce the cost of five insurance, institutional trading costs. At the same time reduce the cost of financing through the financial system reform, through the logistics system reform to reduce logistics costs, through the reform of administration monopoly to reduce labor costs and so on. In addition, while the iron is hot still need their own hard, ultimately depends on increasing ability of the enterprise itself. , experts say, is not only cost reduction policy issues, more important is the issue of reform, but also to improve its own ability truly. Hard, both macroscopic and microscopic unifies, transformation and upgrading of enterprises and industries to real, the transformation and upgrading of China's economy can truly. As the ERW Steel Pipe, galvanized steel pipe, channel steel, galvanized channel steel products such as steel production services vendors, Shinestar group will also improve their own ability, produce more quality products, truly realize the transformation and upgrading.

Why ERW steel pipe Equipments Are Being Introduced

Why ERW steel pipe Equipments Are Being Introduced

Now, a lot of metallurgical equipments in our country can be designed, manufactured and integrated by ourselves. After China jointly designing with foreign countries and summarizing the experiences and lessons of installation, commissioning, usage, maintenance, and transformation of foreign equipments, our current design has reached a high level. 

China with manufacturing capabilities can design and manufacture the world-class advanced metallurgical equipment, especially the ERW (Electrical Resistance Weld) Steel Pipe equipments under present design condition and environment. Then, why some products, especially for high-producing, high automated advanced continuous rolling pipe equipment units, are still need to be introduced? The main problem is the level of the equipment and stability, namely many accidents, poor stability and more slowly production speed.

There is a big problem that is: domestic equipments are cheap and fast. In order to seek for cheap and fast products, it is easy to reduce design level and manufacturing cost, shorten the design and debugging cycle. Therefore, the level is decreased accordingly. In addition, in order to seek for stability, our large state-owned enterprises are generally not willing to bear the liability for risk. This could be the current reason that domestic equipments can only be introduced among the private enterprises.

In addition, we should also be clear that all the highly automated and advanced equipment with high performance are not only be designed and manufactured. They all need serious debugging, commissioning and certain amount of time to a test run. This is an insurmountable stage and only in this way, domestic equipments can march towards a higher level. ERW Steel Pipe production equipments in China now are the time to enter the international market. Some developing countries, especially those who have the iron ore resources, are considering starting building ERW Steel Pipe, factory in dealing with the global crisis as this is a rare opportunity.

ERW, SSAW, LSAW (UOE) difference

ERW, SSAW, LSAW (UOE) difference
Conveying pipe by the different pipe process, can be divided into seamless steel tube (SML), mainly as oilfield gathering tube and small diameter internal high pressure natural gas pipeline, used for long distance oil and gas pipeline of few in number, the vast majority of long distance pipeline is to use high frequency straight seam welded pipe (ERW), spiral submerged arc welding pipe (SSAW), straight seam submerged arc welding pipe (LSAW) three. The table below for the process features of several kinds of steel pipe and quality performance contrast:
High frequency straight seam welded pipe (ERW steel pipe) according to the welding process is divided into different induction welding and resistance welding two forms, using hot rolled wide strip coil as raw material, through the continuous forming, bending, welding, heat treatment, sizing, straightening, cutting process, such as weld short compared with spiral welded pipe, high dimensional accuracy, uniform wall thickness, good surface quality, high pressure, etc. But the disadvantage is that only production of small diameter thin wall pipe, weld easy generation resistant, incomplete fusion, trench corrosion defects. Widely used such as city gas, crude oil transportation.
Spiral submerged arc welding pipe (SSAW) steel strip coil direction when the forming Angle with the center line of the pipe forming (adjustable), forming and welding, the welding seam into spiral, advantage is that the same specifications of the steel strip can produce various specifications of the steel tube diameter, raw material range is larger, the weld can avoid the principal stress, the stress condition is good, the disadvantage is that poor geometry size, weld length compared with straight seam length, easy to produce cracks, porosity, slag, weld defects such as welding, welding stress is tensile stress state. The rules and regulations of general oil and gas long distance pipeline design of spiral submerged arc welding pipe can only be used for 3, 4 regions. Abroad will improve after this process will be raw materials instead of steel plate, forming and welding, then welding and lean, cold expanding, after welding, the welding quality is close to UOE tube, at home there is no such process, is the direction of the spiral tube factory to improve in our country. "West-east gas" spiral tube is still used by traditional craft production, only the pipe hole enlargement. The United States, Japan and Germany, on the whole, negative SSAW, don't think it is proper to use SSAW trunk; Canada and Italy part use SSAW, Russia a small amount of use of SSAW, and have made a very strict complementary condition, due to historical reasons, most domestic trunk or use SSAW.
Straight seam submerged arc welding pipe (LSAW) based on single Zhang Zhonghou plate as raw material, the steel in the mold or molding machine medium-voltage (roll) into the pipe, using double-sided submerged arc welding and ChengJinHang production of hole enlargement. Its finished product specification range is wide, the toughness of the weld, plasticity, good uniformity and compactness, with large pipe diameter, wall thickness, strong resistance to high pressure, low temperature corrosion resistance, etc. In the construction of high strength, high toughness, high quality of long distance oil and gas pipeline, the steel tube are mostly straight seam submerged arc welding of large diameter thick wall pipe. According to the provisions of the API standard in large oil and gas pipelines, when the elevations, sea and city populated area in class 1, 2, straight seam submerged arc welding pipe is the only specify the applicable type. According to the forming methods of different can be divided into:
UOE welded pipe, sheet steel plate after edge bending, after U shape, O forming, welding, welding, mechanical cold expanding process;
JCOE welded pipe: according to "J - E - C - O" after welding, forming, welding process by cold hole enlargement, etc; HME welded pipe: the mandrel rolling method according to the "C - C - O" after forming, welding process by cold hole diameter, etc

Iron and steel industry prices fell, the reason why?

As we all know, often drop large iron and steel industry, the price is extremely unstable, so what is the cause of this phenomenon?Shinestar Steel Research Institute found through research, technology and the characteristics of the iron and steel industry, the cost structure resulted in the imbalance between supply and demand environment quantity adjustment special difficulties.

Specifically, the characteristics of modern steel production technology determines that the industry has a strong scale effect.This means that the iron and steel enterprises need to spend a huge amount of money to buy equipment and equipment to build production systems, resulting in a higher proportion of fixed capital amortization of depreciation in the total cost.Shinestar Steel Group attaches great importance to R & D investment, its R & D production of carbon steel pipe, welded steel pipe, line pipe, galvanized pipe and other excellent products, the market was highly recognized.

Under normal market conditions, the characteristics of the industry makes the steel enterprises with the average cost per unit of output with the output scale and reduce the advantages, is conducive to enhancing the competitiveness of enterprises by expanding the scale, so the rapid growth in market demand under the environment of enterprises with strong expansion impulse.However, the demand for reverse change and under the conditions of excess capacity, the objective needs of sales compensation huge cost sharing, will lead to reduced production enterprises facing special difficulties,makes an ordinary enterprise may have to accept the price is far below the average cost, the formation of the iron and steel industry seems to be more willing to price competition and regardless of the loss of the phenomenon.

At present, the entire industry is under the background of the capacity to understand the difficulties behind the steel enterprises are more conducive to the promotion of structural adjustment.Huge amortization cost constraints, in addition to the mentioned steel blast furnace if stewing furnace boiler stop need extra pay huge cost, which further increased the steel mills production scale down the economic difficulties.In addition, the government protection measures from the Angle of system distortion may prevent enterprises from the number and scale down.

Requires industry to face the question is: in 2009, 460 million tons of crude steel production in China, in 2015 the actual production capacity of more than 1.25 billion tons of crude steel in our country, production of 804 million tons.By profit nature of the enterprise, industry concentration degree increase, corporate profitability increased, the influx of capital, capacity expansion again, a single merger can not limit production capacity expansion.

Product navigation, production escort,Shinestar Steel Group has been very focused on product development and production, which owns the layout of Changsha, Xiangyin, Nanchang, Tianjin four production bases,combined shinestar steel R & D and production of the powerful platform, R & D and production of carbon steel pipe, welded steel pipe, line pipe, galvanized pipe and other excellent products, praised by customers.The future, Shinestar will continue to increase investment, the introduction of advanced technology and equipment, the more the production of more and better quality products, in order to adapt to the development of the globalization strategy.

Advantages of welded pipe

Advantages of welded pipe

Structural welded pipe (tubing) can be used for a wide variety of mechanical applications. It may be used either statically or dynamically. Its close tolerances, good finish, and dense structure make it ideal for parts such as structural support and parts, frames, racks, trailer beds and trailer components, structural components and supports for buildings, bridges, and highways, conveyors, machine parts, ornamental usages and a wide range of applications in industrial, construction, automotive, appliance and agricultural industries.

Welded pipes are generally more cost effective than the equivalent seamless alternative. They are significantly more available both from distributor and mill stocks and from a mill production lead time perspective. With longer lead times seamless tubes can be exposed to unknown alloying price extras that can fluctuate substantially, hence it can be difficult to plan and predict the true costs for the material. Therefore in addition to faster delivery times for Erw tubes, there is the added advantage of lower economical risk. Erw welded steel tubes generally have better surface quality as compared with manufacturing seamless tubes. Seamless tubes are generally made in multiple steps starting with hot extrusion to form the tube hollows from billets.
