What is a Seamless Pipe?

Stainless steel seamless steel pipe is a long strip of steel with hollow section and no joints around it. Stainless steel seamless pipe

Features of stainless steel seamless pipe:

First, the thicker the wall thickness of the product is, the more economical and practical it is. The thinner the wall thickness is, the higher the processing cost will be; Secondly, the process of the product determines its limited performance. Generally, the accuracy of seamless steel pipe is low: uneven wall thickness, low brightness on the inner and outer surface of the pipe, high sizing cost, and there are pockmarks and black spots on the inner and outer surface, which are not easy to remove; Third, its detection and shaping must be processed offline. Therefore, it embodies its advantages in high pressure, high strength and mechanical structure materials

eamless pipes are derived from solid steel that is in sheet or bar form and is formed into                                                                            UNS

Material characteristics

The alloy has the ability to resist chloride environment and sulfide stress corrosion, and its strength is about twice that of standard austenitic stainless steel. When higher mechanical strength / lighter weight is required, the alloy can be successfully used as a substitute for 300 series austenitic stainless steel. It is easy to use many standard arc welding equipment for welding, but it is not recommended for oxyethylene block welding, because carburization of welding metal may occur.
