Stainless steel seamless steel pipe is a kind of long steel with hollow section and no seams around. It is a steel pipe that is resistant to corrosion by weak corrosive media such as air, steam, water and chemical-impregnating media such as acid, alkali and salt. It is also known as stainless acid-resistant steel pipe.
Stainless steel seamless pipe is resistant to air, steam, water and other weak corrosive media and acid, alkali, salt and other chemical corrosive media corrosion of the steel pipe. Also known as stainless acid-resistant steel pipe.
The corrosion resistance of stainless steel seamless pipe depends on the alloying elements contained in the steel. Chromium is the basic element that enables stainless steel to obtain corrosion resistance, when the chromium content of the steel reaches about 12%, chromium and oxygen in the corrosive medium, the role of the steel surface to form a very thin layer of oxidative film (self-passivation film), which prevents further corrosion of the steel matrix. In addition to chromium, stainless steel seamless tube commonly used alloying elements are nickel, molybdenum, titanium, niobium, copper, nitrogen and so on, in order to meet the requirements of a variety of uses on the organisation and properties of stainless steel.

Standard:
GB/T 14976 -- Chinese National Standard
EN10216-5 -- European Union standard
ASME SA312 -- American Society of Mechanical Engineers (ASME) standards


Main production steel pipe grades:
TP304H,TP316L,TP347H,TP321H,TP310S,SAF2507,SAF2205,SAF2304

Usage:
Stainless steel seamless pipe is widely used in petroleum, chemical, medical, food, light industry, machinery and instrumentation and other industrial pipelines and mechanical structural components. In addition, it is lighter in weight when the bending and torsion strength are the same, so it is also widely used in the manufacture of mechanical parts and engineering structures. It is also commonly used for the production of various conventional weapons, gun barrels, artillery shells and so on.
