Stainless steel pipe types and specifications

Stainless steel pipe

Stainless steel pipe is a kind of hollow long round steel, in the industrial field is mainly used for conveying all kinds of fluid media, such as water, oil, gas and so on. According to the different media, stainless steel pipe can be divided into water pipe, oil pipe and gas pipe. In the construction field is mainly used for indoor and outdoor water supply, drainage and HVAC systems. According to the different uses, stainless steel pipes can be divided into water pipes, drainage pipes and HVAC pipes, etc.

Classification according to manufacturing process

1、Welded stainless steel pipe

Welded stainless steel pipe is a stainless steel plate or strip through the welding process to connect the pipe. According to the different welding methods, welded stainless steel pipe can be divided into long welded seam pipe and spiral welded pipe, etc.

2、Seamless stainless steel pipe

Seamless stainless steel pipe is a pipe made by cold drawing or cold rolling process, with high strength and corrosion resistance. According to the different manufacturing process, seamless stainless steel pipe can be divided into cold drawn seamless pipe and hot rolled seamless pipe.

Classification by material
