Preferably, after heating the steel pipe to temperatures of not lower than Ac1, the steel pipe being produced by seam-welding strip … Read more
A fuel-filler tube is made of a welded pipe or ferritic stainless steel. One is a corrosion-resistant austenitic and another has a fuel-supply opening with high accuracy in dimension. The austenitic stainless steel has hardness of 180 HV or less with a work-hardening coefficient of 0.49 or less. Moreover, the ferritic stainless steel has Lankford … Read more
There are a large number of reasons for people using stainless steel pipes: to resist corrosion and oxidation, to resist high temperatures and high pressure, for cleanliness and low maintenance costs, and to maintain the purity of materials. The characteristics of stainless steel allow the design of thin wall piping systems without fear of the … Read more
When we produce multi-wound stainless steel pipe, plastic-deform a hoop material made of a stainless steel sheet applied with a Cu-brazing material on the surface to a multi-wound pipe. After the brazing material melts between the walls of the multi-wound pipe, we should cool the molten brazing material, wherein the Cu-brazing material between the walls … Read more
Duplex stainless steel includes mixed microstructure with about equal proportions of ferrite and austenite. After its first generation, duplex Stainless steel pipe has become more and more popular. Nowadays, high-strength and corrosion resistant super-duplex coil has been produced to apply in the marine and chemical industries, architecture, wire lines, lifting and pulley equipment and so … Read more
A stainless steel pipe elbow has a seamless inner liner with an upstream beveled end, which makes a direction for fluid flow away from the interior surface of the pipe elbow. So it can protect the interior surface of the pipe elbow from abrasive particles included in the fluid. And a downstream beveled end help … Read more
