Processing technology of duplex stainless steel pipe

Processing technology of duplex stainless steel pipe

The riser of offshore oil platform is washed by waves for a long time, so it must have high strength and excellent resistance to pitting corrosion. Among them, dual-phase steel stainless steel pipe has both austenite and ferrite structure, has the advantages of high pitting corrosion resistance coefficient, good mechanical properties and chloride ion corrosion resistance, and is an ideal material for offshore oil platform risers. Then, let's learn about the processing technology of dual-phase steel stainless steel pipe together!

Key points of welding process for duplex steel and stainless steel pipe

Key points of welding process for duplex steel and stainless steel pipe

Dual-phase stainless steel pipe is restricted by its own metallurgical characteristics, which limits the choice of welding methods. Too high welding line energy and too low welding line energy are not ideal. When the energy of the welding line is too high, the cooling speed of the welded joint is reduced, which is conducive to the transition of ferrite to austenite in the heat affected zone and the weld metal to obtain a sufficient amount of austenite, but it is easy to lead to the growth of ferrite grains, produce harmful intermetallic phases and reduce toughness. Then, let's learn what are the main points of the welding process of dual-phase stainless steel pipes!

How much do you know about stainless steel rectangular tubes

How much do you know about stainless steel rectangular tubes

Stainless steel rectangular tube is hollow long steel, because the section is square, so called square tube. Stainless steel rectangular pipes are used as a large number of pipelines for transporting fluids, such as oil, natural gas, water, natural gas, steam, etc. They are light in weight when the bending pipe and torsional strength are the same. Therefore, stainless steel rectangular pipes are also widely used in the manufacture of mechanical parts and engineering structures.
