Heavy Wall Stainless Steel Mechanical Tube Specification:
Heavy Wall stainless steel pipes refer to stainless steel pipes with a ratio of wall thickness to outer diameter greater than 6%. Thick-walled stainless steel pipes are divided into square pipes, round pipes and rectangular pipes according to their shapes.
According to the diameter: small-diameter Heavy Wall stainless steel pipe and large-diameter heavy wall stainless steel pipe. According to the use, it is divided into: heavy wall stainless steel seamless pipe and heavy wall stainless steel welded pipe. Among them, the production methods of heavy wall stainless steel seamless pipes are divided into drawn pipes, rolled pipes and extruded pipes. Generally, drawn pipes are used for medium and low pressure pipes.
