China to curb fast growing steel prices

The Chinese government is encouraging steel companies to sign long-term contracts with coal and downstream steel consuming companies while improving their product quality.The measure, set out in a document issued by five ministry-level bodies, is aimed at stabilizing recently fast growing steel prices and further cutting the industry’s overcapacity.The document, jointly released by National Development and Reform Commission and other four ministries, said that although progress had already been made to cut overcapacity in the steel industry in recent months, the elimination of outdated capacity remains a major challenge.Despite the rapid rise of spot and future prices for steel in the short term and the recent recovery in output and sales performance of steel companies, companies should carry out further efforts to reduce capacity to support economic growth, as the country’s oversupplied steel sector has experienced years of plunging prices and factory shutdowns due to a sluggish economy, it said.Analysts said despite the surge in steel price since the beginning of this year, the API line pipe factory supply-demand situation has not changed and the government document aims to stabilize the market and prevent steel price from overheating and disproportionately rising.According to Wang Guoqing, director of the Lange Steel Information Center, despite the surging steel prices, steel inventories remain high.Figures from the center released that the total inventory of steel in 29 major cities in China exceeded 12.39 million metric tons as of Feb 10, a 35 percent increase compared with three weeks ago, surpassing the peak of 2016.The construction steel saw the biggest growth, more than 8.31 million tons as of Feb 10, 50.8 percent higher than three weeks ago, it said.The government needs to ensure that cutting overcapacity proceeds as planned, he said.According to Huatai Futures, considering the current stable increase in steel output and off-season demand, the inventory for steel in 2017 is believed to exceed 18 million tons, the highest of the past three years.China’s crude steel output rose slightly last year, with crude steel production increased 1.2 percent year on year to 808.37 million tons in 2016, compared with a 2.3 percent decrease in 2015, according to the National Development and Reform CommissionChina plans to reduce steel output by an additional 100 million tons to 150 million tons by 2020. Its 2016 target to cut 45 million tons was achieved ahead of schedule.China will enact stricter rules for trimming steel overcapacity in 2017 after making significant progress in 2016, according to experts.

2017 Has a Long Way to Reduce Capacity

2017 Has a Long Way to Reduce Capacity

The state council information office will held a press conference reference of leading  the economic development of the new normal and deepening the reform of the supply side ,  director of the national development and reform commission, said in 2017 the requirements  of reducing the production capacity will be higher, the pressure will be greater. As a  LSAW steel pipe, DSAW steel pipe, 3 PE anticorrosive coating pipe and other products  production services vendors, Shinestar group has been very attention to reducing  capacity. Shinestar steel research institute believes that have a long way to go to the  process of reducing production capacity, have pressure to just have power.

In 2016, during the process of reducing production capacity ,we encounter many new  problems and new situations, such as the contradiction between supply and demand, price  fluctuations,etc. Price is an important indicator of the baton role is very important for  the supply and demand.

At the beginning of 2016 ,steel price index is only about 60, in the second half of  2016,the price index rose to 100, the price also have a substantial rise. Line, rebar,  cold rolled sheet, plate steel, at the beginning of the year the price also is little  more than 2200 yuan per ton, 3800 yuan by the?end of the year. At the beginning of bohai  sea power coal prices index, 370 yuan per ton, in the second half once topped 680 yuan,  fluctuates up and down at the end of this year or in 600 yuan per ton.

Shinestar steel institute think about it, one is the inventory of the cover, because the  economic operation is smooth, enterprises need to cover the inventory; Second, active  reduce production, steel and coal enterprise according to the demand of production  capacity to compress the output; Third is the ultra falls, is the economic slowdown when  price down; Forth is policy expectations, everyone think efforts in increasing capacity,  may reduce the supply, prices are likely to pick up. But overall, the supply and demand  fundamentals have no fundamental change, price fluctuation is a comprehensive result of  short-term factors, it also can meet the demand of economic stability good, increasing  trend.

There are some more complex factors affecting price fluctuation, such as electricity,  road, rail capacity, etc. For this kind of situation, the national development and reform  commission together with relevant departments, trade associations, etc adopted measures:  the first is the orderly release efficient advanced capacity, increase production. The  second is to guide coal with coal enterprises signed a long-term agreement or contract,  change its way to trade, it also play a positive role. The third is the specification of  coal price index of compiling and publishing. The fourth is a specification of coal  distribution activity, strengthen the security of railway transportation.

Relevant departments are making 2017 plan of steel coal reducing production capacity,  sciencely making mission objectives. To further strengthen the safety standards and  backward production capacity standards, "zombie" companies must as a "key", speed up from  the closure.

China's steel industry should have deep understanding to the importance of capacity,  change thinking methods, deepen the reform of the supply side. As steel whole service in  the field of enterprise, Shinestar group will do a good job in the lead, to speed up the  transformation and upgrading, strive to produce high quality LSAW steel pipe, 3 PE  anticorrosive coating steel pipe, large diameter DSAW steel pipe, and API line pipe factory, for  the healthy and stable development of iron and steel industry efforts.

What is the cause of China's steel exports fell 20%?

Continuation of the end of 2016 China's steel exports decline momentum, China's steel exports in January 2017, continues to decline.Shinestar Steel Research Institute  believes that in recent years, the important factors influencing the Chinese steel exports mainly trade litigation.As a main force in the international steel market,  Shinestar Group production of galvanized pipe, piling pipe, SSAW steel pipe, seamless steel pipe, seamless stainless tube, welded pipe and other products are exported  to Europe, Australia, Africa, North America and other more than and 100 countries and regions, so Shinestar Group has been paying close attention to China's steel  exports.

According to statistics, 2016 1-12 months.China's steel exports suffered from 20 countries and regions of 48 trade remedy investigation,the anti-dumping case 32 cases,  anti-subsidy case 9 cases, safeguards case 7 cases;Compared with 2015, the national increase in the number 6;Caseload rose by 29.7%.

When the start of 2017, a new round of trade disputes are approaching Chinese steel exporters.In addition,  the U.S. Department of Commerce announced on Thursday   finally decided that Chinese imports of stainless steel plate and stainless steel belt get subsidies, and being dumped at below reasonable prices in the us market.Which  are a step closer to impose tariffs on these products.Obviously, there is a widespread of foreign steel products to China anti-dumping and countervailing investigation  and punitive tariff restricts the space of China's steel exports.

However, Shinestar Steel Research Institute believes that the January 2017 decline in steel exports also have a large part of the reason is because the domestic steel  consumption is better than expected, so the foreign trade price upside down caused by steel.At present, the domestic spot sales profit is high, during the Spring  Festival, billet prices locking in 2810 yuan/ton.Look from the current cost line, steel billet manufacturers remained certain profit space, most of the big difference of billet  and the finished product, the overall profit is considerable.In contrast, the international market price is competitive.

Then another major factor in the decline in export volume from the previous year optimistic about the market outlook, which led to an increase in social stocks.According  to the latest research data, the beginning of the new year chicken, the country's five major varieties of steel mills and social inventory reached a total value of 21 million  105 thousand tons, an increase of 23.9%, compared with the previous growth of 30.7%.Therefore, the holiday effect in the same steel exports decline in January plays  an important role.Before and after the Spring Festival, the exporter to price prospects feel uncertain, orders will drop, buyer also want to such as prices, so the wait- and-see mood is strong in the market.

As a service based on Chinese, global steel production enterprises, shinestar group will seize opportunities, meet challenges, and strive to produce more high-quality  galvanized pipe, piling pipe, SSAW steel pipe, seamless steel pipe, seamless stainless tube, welded pipe and API line pipe factory, discrimination against the behavior of the China steel products say "no".

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.

Classifications of Welded Steel Pipe

Classifications of Welded Steel Pipe

Welded steel pipe is shaped up by crimping steel plate or steel belt and then it was made after welding. Welded steel pipe can be classified into longitudinally-welded pipe and spiral welded steel pipe according to the ways of welding. The common forming technique of longitudinally-welded pipe is UOE forming process and JCOE steel pipe forming process. According to the application, welded steel pipe is classified into general welded pipe, galvanized welded pipe, oxygen blast welded pipe, electric wire conduit, metric welded pipe, roller tube, deep well pump pipe, automobile tube, transformer tube, electric welding thin walled pipe, electric soldering special pipe and spiral welded pipe.

General welded steel pipe fabricated by Steel Q195A, Q215A, and Q235A is used for conveying low-pressure fluid. It also can be manufactured by other mild rolled steel for easier welding. Steel pipe should be conducted some experiments such as hydraulic pressure, bending, battering and so on and so forth. Production manufacturers can do a more advanced detection for steel pipe in terms of their own conditions. Welded steel pipe usually has certain requirements for surface quality. The delivery length is usually four to ten meters. Moreover, manufacturers can deliver the goods by sizing or ruler-multiplying according to actual production requirements. The specification of welded pipe in nominal diameter express nominal diameter is different from the actual nominal diameter. According to the regulations of the length of wall thickness, welded pipe has two kinds: thin-wall steel tube and thick-wall steel tube. Steel pipe also has two kinds: thread steel pipe and steel pipe without thread according to pipe ends.

For the price of welded steel pipe is lower than that of south seamless pipe which has the same specifications, welded steel pipe is widely used in low-pressure fluid transmission engineering, steel structure engineering, etc.

API line pipe factory

API line pipe factory

API 5L line pipe according to the production process is divided into the submerged arc welding steel pipe, etc. 8. But the main use of Seamless steel tube (Seamless), high frequency straight seam Resistance Welding steel pipe (Electric - to hold the Arc Welding, shorthand for ERW), straight seam Submerged Arc Welding pipe (Longigudinally Submerged Arc Welding, shorthand for LSAW), spiral seam Submerged Arc Welding pipe, Spirally Submerged Arc Welding, shorthand for SSAW), etc.

Straight seam submerged arc welding pipe press forming method is divided into UO (UOE), RB (RBE), JCO (JCOE), etc. The steel plate in forming mould pressing U first, then pressed into an o-ring, and then evaluated for submerged arc welding, after welding are usually at the end or span range (Expanding) called the UOE welded pipe, hole diameter is not called UO of hole diameter welded pipe. The steel plate roller bend forming (Roll Bending), and then evaluated for submerged arc welding, after welding for RBE hole diameter welded pipe or not for hole enlargement RB welded pipe. Will the steel plate according to the order of type J - C - O forming, hole enlargement of JCOE welded pipe after welding or not for hole enlargement JCO welded pipe. Of the LSAW welded pipe is a widespread use of UOE. High frequency electric resistance welded pipe ERW mainly by high frequency current skin effect and proximity effect melted the tube embryo edge, then under the action of squeezing roller pressure welding, its characteristic is no foreign filler metal, heat affected zone is small, high production efficiency. Spiral welded pipe used in long distance line SSAW pipe has a long history, is our country at present mainly adopts the line pipe.
