Stainless steel tube: from the tube (plate, belt) directly into the shape of welded pipe, the main process for the strip forming, welding, sizing. Features: less consumption processes, engineering process is simple, product consumption cycle is short, slightly lower product accuracy.

  Second stainless steel tube production methods: from the tube (plate, with) the first direct welding forming a certain size of pipe, and then after cold-drawn or cold rolled into waste pipe, known as DOM welded steel pipe. The main process is forming, welding, sizing, cold or cold drawing (with mandrel or without mandrel), or continuous drawing (ie, welding - cold drawn with the consumption line). Features: the consumption process dispersion, process and consumption cycle is long, accounting for the air product size, product precision, surface brightness, mechanical properties and microstructure state.

  The third type of stainless steel production methods: from the tube (plate, with) the first direct welding forming a certain size pipe, into the continuous reducer to reduce the diameter of the tube into a waste tube. The main process for forming, welding, continuous cold reducing diameter. Features: Compact consumption process, simple process, high efficiency unit consumption, the scope of change quickly, for consumption of small diameter and thin-walled welded steel pipe
