  • Stainless Steel Pipe, Pros & Cons

    Stainless steel traces its roots back to the early 1800’s in France. Carbon steel is alloyed with chromium to produce a corrosion resistant metal. During this process, other elements are included to develop the various alloys that are used today. Stainless steel pipe and stainless steel tubing is often used in construction for its appearance as well as its strength and corrosion resistance. During a process called passivation, a thin layer of chromium oxide forms on the outer surface of the stainless components. It is this barrier that protects the base metal from the elements.
  • What Is ERW Steel Pipe?

    What is ERW? ERW is an abbreviation of electric resistance welded pipe. It is plate rolled to turn out to be a pipe and welded by making use of the process of electric resistance welding.
  • Supply SAE1527 seamless steel pipe

    As one of the biggest SAE1527 Seamless steel pipe supplier in China, we are qualified to supply you SAE1527 seamless steel tubes/steel pipes. This SAE1527 applies to the mechanical structure and general engineering structure for steel tubes. Tube/Pipe is mostly used in the annealed or hardened condition. However, it can also be heat treated, quenched and tempered. We also can arrange inspection from the third party like SGS,BV,DNV,PMI and so on, the goods we supplied will be of high quality and with required standard. We have been export steel for many years , if you have any question about SAE1527 pipe , please inform me ,thanks .
  • 16Mo3 seamless steel pipe

    Equivalent Material: 15Mo3 under DIN standard A204Gr.A under ASTM standard Delivery Conditions: Normalizing; Normalizing+Tempering, Quenching+Tempering
  • 15NiCuMoNb5-6-4 seamless pipe features

    Feature: The influence of merchantmen on property of 15NiCuMoNb5-6-4 pipe is researched. It is found that hardness descend and then raise, and strength gradually descend when tempering temperature ascend. Hardness descend and toughness raise when tempering time add. The best tempering technical of this steel is that tempering temperature is 630-660℃.
  • Sell 100Cr6 seamless steel pipe China

    100Cr6 seamless steel pipe China is supplied with large stock.
  • Baosteel cuts main steel products prices

    China's biggest listed steelmaker Baoshan Iron & Steel Co Ltd will slash the prices of its mainproducts for September bookings by up to 3.4 percent, the third reduction in a row since June,indicating a lack of market confidence in the short run.The Shanghai-based manufacturer will cut hot-rolled coil prices by 100 yuan ($15.7) per tonand cold-rolled coil prices by 150 yuan per ton.
  • Straight seam steel pipe manufacturing process

    The main processing method of steel pipe is forged by forging hammer, the reciprocating impact or pressure of press the blank into the desired shape and size. Then you need to extrusion, rolling and pulling steel process. Extrusion: steel metal on the closed extrusion Jane, end pressure, the metal from the die hole of the provisions of the extrusion processing methods are the same shape and size of the finished product;
  • The advantage of Stainless Steel Pipe

    Stainless steel pipe can be ordered in 20-foot and 40-foot lengths and even 60-foot lengths for pipe diameters up to 16-inches. Ductile iron is only available up to 20 feet in length. The number of joints, and therefore cost, is reduced for long stainless steel pipe strings.
  • Devaluation of RMB is expected to continue to weaken in the second half of the year

    In the first half of 2017, the market's benchmark forecast is a far cry from the beginning of the year.The most dramatic change in expectations is the renminbi's exchange rate and the fed's tightening pace. At the beginning of the year it was widely believed that the yuan would break seven times against the dollar, and yellen would continue to raise the doves to the end. However, the renminbi has held steady against the dollar in mid-year and expectations of a weaker renminbi have weakened sharply, while the fed has raised its expectations for a hawkish rate hike in two successive hikes in March and June.
  • The Classification of Carbon Steel Pipe

    Classified by Production Methods 1. Seamless Steel Pipe - hot rolled seamless steel pipe, cold rolled seamless steel pipe, cold drawn seamless steel pipe2. Welded Steel Pipe - longitudinal welded pipe, spiral welded pipe, electric resistance welded pipeClassified by Cross-sectional Shape1. Simple section steel pipe - round carbon steel pipe, square carbon steel pipe, rectangular carbon steel pipe, oval carbon steel pipe ect. 2. Complex section steel pipe - hexagonal carbon steel pipe with unequal edge, five plum shaped carbon steel pipe, double convex carbon stee pipe, double concave carbon steel pipe ect.
  • Difficulties in Wall Thickness Control for Straight Seamless Steel Pipe Process

    Straight seamless steel pipe wall thickness control is a difficult production. At present, the straight seam steel pipe manufacturers to improve the wall thickness in the production of precision uses the methods generally including:1, Tube heating Heating to the average to prevent rapid up and down temperature. Each take-off and landing temperature is to maintain a smooth slow, the maximum rise and fall temperature does not exceed 30 ℃.2, Rolling mill mandrel Average wall thickness of thick wall tube and solid billet make the probability of mandrel bending deformation significantly reduced, can effectively improve the wall thickness of the precision.
