Stainless steel seamless pipe is a steel pipe resistant to corrosion by weakly 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 stainless steel seamless pipes depends on the alloying elements contained in the steel. Chromium is the basic element for obtaining corrosion resistance of stainless steel. When the chromium content in steel reaches about 12%, chromium interacts with oxygen in the corrosive medium to form a thin oxide film (self-passivation film) on the surface of the steel, Can prevent the steel matrix from further corrosion. In addition to chromium, nickel, molybdenum, titanium, niobium, copper, nitrogen, etc. are commonly used as alloying elements for stainless steel seamless pipes to meet the requirements of various applications on the structure and performance of stainless steel.
The thicker the thickness of the stainless steel seamless pipe, the more economical and practical it is. The thinner the wall thickness, the higher its processing cost. Secondly, the product's process determines its limited performance. The accuracy of the seam steel pipe is low: uneven wall thickness, low brightness on the inside and outside of the pipe, high scale cost, and pits and black spots on the inside and outside, which are not easy to remove. Third, its detection and shaping must be processed offline. Therefore, it shows its superiority in terms of high pressure, high strength, and mechanical structural materials.
Stainless steel seamless pipe is widely used in petroleum, chemical, medical, food, light industry, mechanical instrumentation and other industrial pipelines and mechanical structural components. In addition, when the bending and torsional strength is the same, the weight is light, so it is also widely used in manufacturing mechanical parts and engineering structures. It is also often used in the production of various conventional weapons, barrels, and shells.
