Characteristics
First, the thicker the wall thickness of the product, the more economical and practical, the thinner the wall thickness, its processing cost will increase greatly; secondly, the process of the product determines its limited performance, generally seamless steel pipe accuracy is low: uneven wall thickness, low brightness inside and outside the tube, high sizing cost, and inside and outside the surface also pockmarks, black spots are not easy to remove; third, its detection and shaping must be offline treatment. Therefore, it shows its superiority in high pressure, high strength and mechanical structure.
Stainless steel seamless pipe is resistant to air, steam, water and other weak corrosion medium and acid, alkali, salt and other chemical corrosion medium corrosion steel pipe. Also known as stainless acid-resistant steel pipe.
The corrosion resistance of stainless steel seamless tubes depends on the alloying elements contained in the steel. Chromium is the basic element to obtain corrosion resistance of stainless steel. When the chromium content in steel reaches about 12%, chromium acts with oxygen in corrosive medium and forms a thin oxide film (self-passivation film) on the steel surface, which can prevent the steel matrix from further corrosion. In addition to chromium, nickel, molybdenum, titanium, niobium, copper and nitrogen are commonly used in stainless steel seamless pipes to meet the requirements of stainless steel structure and properties for various uses.
Stainless steel seamless pipe is a hollow long circular steel, widely used in petroleum, chemical, medical, food, light industry, mechanical instruments and other industrial transport pipelines and mechanical structure components. In addition, when bending and torsion strength is the same, the weight is lighter, so it is also widely used in the manufacture of mechanical parts and engineering structures. Also often used for the production of a variety of conventional weapons, barrel, shells and so on.
