Stainless steel alloy steel pipe is a high alloy steel that can resist corrosion in air or chemical corrosive medium.
Stainless steel is a kind of steel with beautiful surface and good corrosion resistance. It does not need to undergo surface treatment such as color plating, but gives play to the inherent surface properties of stainless steel.
Alloy pipes have hollow sections and are widely used as pipelines for conveying fluids, such as oil, natural gas, gas, water and some solid materials.

Production process

Hot rolling (extrusion of seamless steel pipe): round tube blank → heating → piercing → three-roll cross rolling, continuous rolling or extrusion → tube stripping → sizing (or reducing) → cooling → tube blank → straightening → hydraulic test (or flaw detection) → marking → warehousing.
Cold drawn (rolled) seamless steel pipe: round tube blank → heating → piercing → heading → annealing → pickling → oiling (copper plating) → multi-pass cold drawing (cold rolling) → blank tube → heat treatment → straightening → hydraulic test (flaw detection) → marking → warehousing
