Purpose classification. According to different application scenarios, stainless steel pipes can be divided into stainless steel pipes for mechanical structures, stainless steel pipes for fluid transmission, stainless steel heat exchange pipes, stainless steel pipes for pneumatic components, etc.
Manufacturing process classification. The manufacturing process of stainless steel pipes includes cold drawing method, cold rolling method, cold working method, hot rolling method, etc. Among them, the pipes made by cold drawing method have smooth surface, high dimensional accuracy and good mechanical properties, and are widely used in high-precision occasions; cold rolling method The pipes manufactured have the characteristics of smooth surface, high dimensional accuracy, and high strength, and are mostly used in high-pressure transmission fields; pipes manufactured by the hot rolling method have good toughness and high tensile strength, and are usually used in situations where low-viscosity liquids are transported.
Classified by pipe end shape. Stainless steel pipes can be divided into plain pipes and threaded pipes (threaded steel pipes) according to the condition of the pipe ends. Threaded pipes can be divided into ordinary threaded pipes (pipes for low-pressure transportation such as water and gas, which are connected by ordinary cylindrical or conical pipe threads). ) and special threaded pipes (pipes for petroleum and geological drilling, for important threaded pipes, special threaded connections are used).
