stainless pipe is a steel pipe that is resistant to weak corrosive media such as air, steam, and water, and chemically corrosive media such as acid, alkali, and salt. Also known as stainless acid-resistant steel pipe.

The corrosion resistance of seamless stainless steel depends on the alloying elements contained in the steel. Chromium is the basic element for stainless steel to obtain corrosion resistance. When the content of chromium in steel reaches about 12%, chromium and oxygen in corrosive medium act to form a thin oxide film (self-passivation film) on the surface of steel. , which can prevent further corrosion of the steel matrix. In addition to chromium, the commonly used alloying elements for stainless steel seamless pipes are nickel, molybdenum, titanium, niobium, copper, nitrogen, etc., to meet the requirements of various uses for the structure and properties of stainless steel.

pipe stainless is a kind of hollow long round steel, which is widely used in petroleum, chemical, medical, food, light industry, mechanical instrumentation and other industrial transportation pipelines and mechanical structural components. In addition, when the bending and torsional strength are the same, the weight is lighter, so it is also widely used in the manufacture of mechanical parts and engineering structures. It is also commonly used to produce various conventional weapons, barrels, shells, etc.

First, the thicker the wall thickness of the stainless steel seamless pipe, the more economical and practical it is, and the thinner the wall thickness, the higher its processing cost;

Secondly, the process of stainless steel seamless pipe determines its limited performance. Generally, the precision of seamless steel pipe is low: uneven wall thickness, low brightness on the inside and outside of the pipe, high cost of sizing, and there are pits and black spots on the inside and outside that are not easy to remove;

Third, the detection and shaping of stainless steel seamless pipes must be processed offline. Therefore, it reflects its superiority in terms of high pressure, high strength, and mechanical structural materials.
