Seamless stainless steel pipe manufacturers  

Seamless stainless steel pipe is a hollow section with no seams. The thicker the wall thickness of the product, the more economic and practical, the wall thickness is thinner, its’ processing cost will be substantially increased; the product process determines its performance limitations.

The low accuracy of the general seamless stainless steel pipe: non-uniform wall thickness, low brightness of the inner surface, the high cost of fixed length, and it is not easy to remove the black spots on the inner and outer surface, its detection must be processed offline. Therefore, it shows its superiority in high pressure, high strength and mechanical structure materials.

Types of seamless stainless steel pipes:

1)According to the rolling method:
Hot rolled seamless stainless steel pipe, hot extrusion seamless stainless steel pipe and cold draw seamless stainless steel pipe.
2) According to the microstructure of stainless steel:
Martensitic seamless stainless steel pipe, austenitic seamless stainless steel pipe

The common standards of seamless stainless steel pipes:

GB3090-82, GB5310-95, GB3087-82, GB3089-92, GB9948-88, ASTM A213, ASTM A269, ASTM A312, ASTM A450, ASTM A530, ASTM A789, JIS G3456-8, JIS G3448-88, JIS G3459-88, JIS G3463-88 

The common material grades of the seamless stainless steel pipes:

201(1Cr17Mn6Ni5N), 202(1Cr18Mn8Ni5N), 301(1Cr17Ni7), 302(1Cr18Ni),304(0Cr18Ni9), SS304, TP304, 304L(00Cr19Ni10)、SS304L、TP304L, 321(1Cr18Ni9Ti)、SS321、TP321
