Stainless steel seamless tube

Stainless steel seamless pipe is a kind of hollow section, no joints around the strip steel.
The characteristics of stainless steel seamless tube: first, the thicker the wall thickness of the product, it is more economical and practical, the thinner the wall thickness, its processing cost will rise significantly; Second, the process of the product determines its limited performance, general seamless steel pipe accuracy is low: uneven wall thickness, low brightness inside the outer surface, high cost of sizing, and the inner surface and pitting, black spots are not easy to remove; Third, its detection and shaping must be handled offline. Therefore, it has its advantages in high pressure, high strength and material for mechanical structure.

The composition of stainless steel seamless tubes, according to the chemical composition and mechanical properties of domestic seamless tubes, such as 10, 15, 20, 25, 30, 35, 40, 45 and 50 steel should comply with the provisions of GB/T699-88. Imported seamless pipes shall be inspected according to relevant standards stipulated in the contract. The chemical composition of 09MnV, 16Mn, 15MnV steel should comply with the provisions of GB1591-79. Mainly used in fluid conveying pipe, boiler plant, engineering, machinery processing plant.
