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.
Features Introduction:
Firstly, the thicker the wall thickness of the product, the more economic and practical it is, the thinner the wall thickness, the processing cost of it will rise dramatically; Secondly, the process of the product determines its limitation performance, the general seamless steel pipe precision is low: wall thickness is not uniform, the tube inside the appearance of the brightness is low, the cost of fixing the size of the pipe is high, and there is a pockmarked inside the appearance of the black spots are not easy to remove; Thirdly, it must be processed offline for its detection and shaping. Therefore, it reflects its superiority in high pressure, high strength, mechanical structure materials.
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.
For 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.
