Stainless steel tube is a kind of hollow long round steel.Stainless steeltubes are mainly used in piping systems for transporting liquids or gases.We manufacture steel pipes from alloy steel containing nickel and chromium, which makes stainless steel corrosion-resistant.Stainless steel tubing is oxidation resistant and a low maintenance solution for high temperature and chemical applications. Because stainless steel tubing is easy to clean and sterilize, it is also required for use in food, beverage and pharmaceutical applications.
Stainless steel tubes have good corrosion resistance, which is extended from stainless steel itself in contact with water or in a humid environment for a long time without rusting. Some stainless steel pipes developed by modern technology can be washed by chemical liquids for a long time without rusting. damage occurs;
Stainless steel tube has good ductility, which is its second major advantage, because the structure of stainless steel material can withstand a certain external force, although it will deform to some extent, but generally there will be no brittle failure like cast iron pipe. .
The stainless steel tube has a long service life, which is why the stainless steel will not easily undergo physical and chemical reactions whether it is buried in the ground or exposed to the air.

Stainless steel tubes mainly go through 14 production processes: a. Round steel preparation; b. heating; c. Hot rolling perforation; d. Cut the head; e. Pickling; f. Grinding; g. Lubrication; h. Cold-rolled processing; i. Degreasing; j. Solution heat treatment; k. Straightening; l. Cut pipe; m. Pickling; n. Product testing.
