What is Seamless steel pipe?

Stainless steel seamless pipe is a steel pipe that is resistant to weak corrosive media such as air, steam and water and chemical corrosive media such as acid, alkali and salt. Also known as stainless acid resistant steel pipe.
The corrosion resistance of stainless steel seamless pipe depends on the alloy elements contained in the steel. Chromium is the basic element that makes stainless steel obtain corrosion resistance. When the content of chromium in the steel reaches about 12%, chromium reacts with oxygen in the corrosive medium to form a thin oxide film (self-passivation film) on the steel surface, which can prevent the further corrosion of the steel substrate. In addition to chromium, the common alloy elements of stainless steel seamless pipe include nickel, molybdenum, titanium, niobium, copper, nitrogen, etc., to meet the requirements of various applications on the structure and properties of stainless steel.
Stainless steel seamless pipe is a kind of hollow long round steel, widely used in oil, chemical, medical, food, light industry, mechanical instruments and other industrial transmission pipes and mechanical structural components. In addition, when the bending and torsional strength are the same, the weight is relatively light, so it is also widely used to manufacture mechanical parts and engineering structures. It is also commonly used to produce various conventional weapons, barrels, shells, etc.
