Description:
Stainless steel seamless pipes are also called stainless acid-resistant steel pipes. They are steel pipes that are resistant to corrosion by weak corrosive media such as air, steam, and water, and chemically corrosive media such as acids, alkalis, and salts. .
The corrosion resistance of stainless steel seamless pipes depends on the alloying elements contained in the steel. Chromium is the basic element that makes stainless steel corrosion-resistant. When the chromium content in steel reaches about 12%, chromium reacts with oxygen in the corrosive medium to form a very thin oxide film on the steel surface, which can prevent further corrosion of the steel matrix.

Manufacturing process of stainless steel seamless pipe:
Hot rolling (extruded seamless steel pipe):
round tube billet → heating → perforation → three-roller oblique rolling, continuous rolling or extrusion → tube removal → sizing (or reducing diameter) → cooling → straightening → water pressure test (or flaw detection) → marking → storage
Cold drawn (rolled) seamless steel pipe:
round tube billet → heating → perforation → heading → annealing → pickling → oiling (copper plating) → multiple cold drawing (cold rolling) → billet tube → heat treatment → straightening → water pressure test (flaw detection) → marking → storage.
What is the difference between hot rolling and cold rolling?
The rolling method of cold drawn (rolled) seamless steel pipe is more complicated than that of hot rolling (extruded seamless steel pipe). The first three steps of their production process are basically the same. The difference starts from the fourth step. After the round tube billet is hollowed out, it needs to be headed and annealed. After annealing, it needs to be pickled with a special acidic liquid. After pickling, oil is applied. Then it is followed by multiple cold drawing (cold rolling) and then billet tube, special heat treatment. After heat treatment, the cooling process is the same as that of steel pipe.
