Performance damage and possible solutions for stainless steel pipes after cold processing

In order to enhance the performance of the stainless steel pipe, usually use some cold processing technology, such as cold drawing, cold rolling, cold rolling, cold, cold, cold expansion distortion, but finally achieve effect, also will inevitably suffer some damage, these cold working process and welding processing, will damage the performance of the stainless steel pipe, […]

Problems encountered in welding thin wall stainless steel tubes

When welding thin wall stainless steel, the technical level requirements are very high, because in the welding of this kind of material, will face many problems, such as construction site problems, heat treatment problems, thermal expansion and cold contraction problems, the following to tell the solution to these problems. First of all, the construction capacity, […]

Effect of molybdenum element in stainless steel welded pipe

Molybdenum is mainly used in iron and steel industry, generally more than 80% is added to the molybdenum in steel, only about 20% to produce metal molybdenum, molybdenum alloy, super alloy and special chemical products, they are mainly used in petroleum chemical industry, light industry, electronics and other high-tech fields. Molybdenum in stainless steel welded pipe may […]

Comparison of performance between duplex stainless steel pipes and other stainless steel pipes

Duplex stainless steel pipe is in the solution structure of ferrite in the microstructure and the austenite microstructure about each accounted for 50%, the less content usually have reached 30%, so the duplex stainless steel pipe with ferrite stainless steel and austenitic stainless steel pipe properties. Among them, compared with austenitic stainless steel pipe, duplex stainless […]

Introduction of surface treatment methods for stainless steel pipe

With the rapid development of the domestic energy industry, application of stainless steel tube is rapidly increasing, the corrosion in oil and gas pipeline construction process, surface treatment of stainless steel tube is one of the key factors determining the service life of the pipeline corrosion, but also an important prerequisite for the anticorrosion layer and stainless […]
