Pipe Application: Oil Pipeline

The main type of pipe that used in Oil pipeline is carbon steel pipe, including seamless steel pipe and welded steel pipe.

Seamless steel pipe is applicable to transport strong corrosive oil or transport in the high temperature conditions as it has the characteristics of high strength, specifications and more features. The technology of seamless steel pipe includes hot rolling and cold drawn.

Welded steel pipe includes LSAW steel pipe and SSAW steel pipe. The process characteristics of carbon steel pipe leads the steel pipe to tend to become brittle at low temperatures, so it is mainly applied to the normal temperature pipeline, the use of pipe temperature should not exceed 300 degrees Celsius. In general, the temperature of ordinary carbon steel pipe is between 0 to 300 degrees Celsius. If using the high-quality carbon steel pipe, the temperature range can be broadened from -40 to 450 degrees Celsius. The experimental pressure of the steel pipe is generally 1.5 times of the nominal pressure. When the temperature of the material delivered does not exceed 200 degrees Celsius, the working pressure is the nominal pressure. When the temperature exceeds 200 degrees Celsius, the working pressure should be correspondingly lower than the nominal pressure.

Prime Steel Pipe as an excellent manufacturer, has complete production lines to produce SSAW steel pipe. No matter what requirements you have, Prime Steel Pipe will surely make you satisfied.

Heat the iron and steel industry will continue in 2017?

In 2017, China's steel industry will still in a critical period of transformation and upgrading, the situation is still grim. As the welding steel pipe, seamless steel pipe, galvanized pipe, straight seam submerged arc welding pipe, carbon steel pipe manufacturer, scaffolding, and other products production services vendors, Shinestar group thinks, although in 2016 iron and steel enterprise profitability, a successful counter attack, but it is not optimistic.

Industry fundamentals, the situation of oversupply of steel market is not a fundamental change, iron and steel enterprise's profit foundation is still not strong enough. On the one hand, the high volatility in the prices of raw materials, such as coke, ore, iron and steel enterprise profit control to bring greater pressure. Since this year social inventory exploded on the other hand, the first week of Spring Festival domestic steel inventories rose to 50%, high inventory needs certain time, may be longer than expected time before industry. And monetary policy fine-tuning since this year, before the Spring Festival, the central bank raised lending facilities (MLF) interest rates after the mid, and after the central bank raised its multiple deadline reverse repurchase and stock lending facilities (SLF) interest rates, interest rates from the long side interest rates to short end, up market interest rate curve, liquidity tightening signs for a more cautious attitude to the futures market operation, greatly influenced by phase current linkage. There are some unclear steel spot market direction.

The ministry released earlier this month the first announcement to cancel the specification of 35 list of iron and steel enterprise, this is the 2012 years since its steel industry standard management, start list by "addition" change "subtraction" for the first time. Means that dissolve the iron and steel industry in 2017 will further strengthening its excess capacity.

Recently, the five ministries jointly issued by the "about further implement pressure balance policy promotes the steel market has kept running notice. "Notice" pointed out that before the recovery period of steel prices, show that the serious problem of excess steel production capacity in our country have a certain degree of improvement. Recently appeared steel prices of spot and futures markets and rapid rise in the short term, but China's steel industry oversupply problem has not been fundamentally solved. Also notice again, to crack down on illegal production and sales "groud of steel" behavior, before the end of June 2017 in accordance with the law to ban the production of construction steel power frequency furnace, intermediate frequency furnace capacity, manifests the country determined to clean up behind the capacity determination.

Clean up 2017 "groud of steel" as an important content to work capacity. Provinces such as guangdong, jiangsu, hebei, sichuan also have issued relevant documents, determined to crack down on illegal production "groud of steel" production and sales. Iron and steel industry in China has developed from incremental into the stage of development, reducing the overall production capacity surplus part of the advanced capacity are resolve, "groud of steel" must clean up all.

As a based in China, service global steel production enterprises, Shinestar group will work hard to realize the transformation and upgrading, combined with their own situation to make strategic plan, produce the high quality of welded steel pipe, seamless steel pipe, galvanized pipe, straight seam submerged arc welding pipe, carbon steel pipe, scaffolding, and other products, promote the competitiveness of the enterprise.

Low Carbon Steel Pipe Manufacturer

Low Carbon Steel Pipe Manufacturer

Low carbon steel pipe manufacturer is one type of carbon steel pipe with the carbon content less than 0.25%. It is also known as mild steel pipe due to its low strength and low hardness. Low carbon steel pipe includes most of the ordinary carbon structural steel pipe and part of the high quality cabron structural steel pipe. Most of low carbon steel pipe without heat treatment is applied for structural engineering, and some of low carbon steel pipe with heat treatment and carburizing is applied for wear-resistant mechnical parts.

Since low carbon steel pipe has a very low carbon content and poor machinability, normalizing treatment can improves its machinability. 

The annealing organizations for low carbon steel pipe is the ferrite and a small amount of pearlite which creates low strength, low hardness, good plasticity and toughness. Therefore, low carbon steel pipe has good cold formability, it can be cold formed by curling, bending, stamping and other methods. Besides, it also has good weldability. The carbon content is from 0.10% to .030% which is easy to accept a variety of processing such as forging, welding and cutting. Commonly it is used in the manufacturer of chains, rivets, bolts, shaft and so on.

How to Choose the SSAW Carbon Steel Pipe Manufacturer

How to Choose the SSAW Carbon Steel Pipe Manufacturer

Usage of SSAW carbon steel pipe is relatively high, the application is very wide, it should be how to choose before in the selection to pay attention to quality.

The first method is a more professional detection method, that is, by the strength of the pressure vessel to be detected. Commonly, we use atmospheric pressure and water pressure to detect, in this way can detect the working conditions of the SSAW carbon steel pipe in the pressure working environment, but also to detect the tightness of the spiral steel pipe, generally take the atmospheric pressure detection, because such security Relatively high, and if the water vapor pressure through the test, then the need to remove the spiral pipe after the water, too much trouble.

The second method is also relatively simple, that is, through the surface of observation. With the naked eye found in the spiral steel pipe in the welding and size of the problem, if necessary, you can also use the standard sample and the products to be compared to find the problem. In general, formal steel pipe company in the production is relatively perfect, on the other hand to beat the metal pipe, if the sound is very crisp and the echo is not very dirty, then the name is the latest selection of steel pipe, rather than scrap steel recycling.

These two methods are commonly used, we can choose a way to test, more secure way is the best to the regular manufacturers, can reduce the use of the process of abuse.

carbon steel pipe manufacturing

carbon steel pipe manufacturing

The raw material of carbon steel pipe is round pipe billet. The round pipe billet is cut by the cutting machine and processed into the billet with the length of 1 meter. And then sent to th furnace tobe heated by the conveyer belt. The billet is fed into a furnace and heated at a temperature of about 1200 degrees Celsius. The fuel is hydrogen or acetylene. Furnace temperature control is a key issue. After the round tube billet to go through the pressure piercing machine to wear empty. Generally more common punching machine is conical roller piercing machine, this punching machine production efficiency is high, product quality is good, perforation expansion diameter large, can wear a variety of steel. After piercing, the round tube blank has been three-roll cross-rolling, rolling or extrusion. Squeeze after the tube diameter. Sizing machine through the high-speed rotation of the cone drill bit into the steel embryo drilling, the formation of steel pipe. The inner diameter of the pipe is determined by the outside diameter of the sizing bit. Steel pipe after sizing, into the cooling tower, through the water cooling, the cooling pipe, it is necessary to be straightened. After straightening by the steel pipe sent to the metal detector (or water pressure test) for internal testing. If the pipe has cracks, bubbles and other problems, will be detected. After the quality of steel pipe but also through rigorous manual selection. After the quality inspection of steel pipe, spray paint with the number, size, production lot number. And suspended by the crane into the warehouse.

Carbon Steel Pipe Production

Carbon steel pipe can be divided into seamless steel pipe, straight seam steel pipe, spiral steel pipe, high-frequency welded steel pipe. Rolled seamless carbon steel pipe is the raw material of round tube, tube embryo to be cut through the cutting machine into a length of about 1 m of blank, and the conveyor belt to the furnace heating. The billet is fed into a furnace and heated at a temperature of about 1200 degrees Celsius. The fuel is hydrogen or acetylene. Furnace temperature control is a key issue. After the round tube billet to go through the pressure piercing machine to wear empty. Generally more common punching machine is conical roller piercing machine, this punching machine production efficiency is high, product quality is good, perforation expansion diameter large, can wear a variety of steel.

Cold drawn (rolled) carbon steel seamless steel pipe: round tube → heating → punching → start → annealing → pickling → oiling (copper) → multi-pass cold drawing (cold rolling) → tube → heat treatment → straightening → water pressure test (testing) → marking → storage

Carbon steel seamless steel pipe because of its manufacturing process is different, is divided into hot-rolled (extrusion) seamless steel tubes and cold drawn (rolled) seamless steel pipe two. Cold drawn (rolled) tube is divided into two kinds of round tube and special-shaped tube.

In addition, GB / T17396-1998 (hot-rolled seamless steel pipe for hydraulic support), GB3093-1986 (diesel engine high-pressure seamless steel pipe), GB / T3639-1983 (cold drawn or cold-rolled precision seamless steel pipe), GB / T3094-1986 (cold drawn seamless steel pipe shaped steel pipe), GB / T8713-1988 (hydraulic and pneumatic cylinder with precision diameter seamless steel pipe), GB13296-1991 (boiler, heat exchanger with stainless steel seamless pipe), GB / T14975 (Seamless Steel Tube for Automotive Axle Bushings), API SPEC5CT-1999 (Casing and Tubing), GB / T14976-1994 (Seamless Steel Pipe for Fluid Conveying) Specification) and so on.

Price Adjustment for Q345 Welded Carbon Steel Pipe

Price Adjustment for Q345 Welded Carbon Steel Pipe

The focus of the current market or gathered in the social stock of Q345B longitudinal welded pipe, the five statistics on Friday the total inventory of the five Q345B longitudinal welded pipe stock total 8.44 million tons, 0.4% WoW, down 9.2%; five Q345B straight seam Weld pipe plant inventory total of 4.899 million tons, an increase of 4.9% WoW, down 16.3% year on year. If you look at the current social stock of Q345B longitudinal welded pipe absolute quantity, there is no doubt that the current market inventory pressure is small, but the steel plant inventory began to rise is worth noting. Because the five major varieties of social stock as a result of the decline in the sample caliber representative, in fact, outside the caliber of the amount of resources or trends in the trend of the sample is not the same, so the process of resource dispersion trend is often the core regional stock transfer to non-core areas .
In addition, as the "car limit set" strictly enforced, in fact, the increase in the amount of in-transit resources have been ignored, taking into account the limited capacity of vehicles in southern China, for example, motor transport cycle basically from the past 1-2 days to 2-5 days , That is, the amount of vehicles in transit than in the past to look through; the same token, in the original fuel materials also exist such a situation. If the vehicle capacity does not improve, this resource does not constitute a pressure on the market, but this year, truck sales rose significantly, from January to October 2016 more than 40 tons of semi-tractor sales rose 98.5%; 25-40 tons between the semi-traction Car sales rose 16.6%; 25 tons and below semi-tractor sales rose 119% year on year.
But in October, more than 40 tons, 25-45 tons and 25 tons the following semi-tractor sales were up 45.9%, 68.4% and 117.8%. In general, the truck sales to the road takes 50 days or so, once the capacity to enhance, ask who is willing to increase the transport cycle to extend and bear the burden of resources and risk of funds in transit, then the latter is not there will be a lot of transit resources into social stock To be tested!
Raw materials, the domestic coal mine production safety requirements more stringent, the major domestic coal mines to ensure safe production, production than the previous period have different degrees of decline, making most of the coking plant inventory of refined coal declined support coking coal prices continue to be strong . Affected by this, high-grade iron ore spot prices are also supported, the current futures and spot basis also reflects this trend. So hope that the original fuel material spot fell may not be desirable, but rather need to pay attention to the price difference between the repair. Of course, this premise is the production of steel production enterprises will not substantially

cut.
