Stainless Steel Seamless Pipe is a long steel which has hollow section and no seams. It is produced by boring holes on solid steel billets or solid pipe billets, and do Hot-rolling, cold-rolling or cold-drawing later. It is Widely used for the pipings for fluid transfer, such as petrol, natural gas, water, coal gas, steam, etc. In addition, as the weight is light when in the same bending and tensile strength, it's also widely used for manufacturing machinery and construction structural components. Usually etc.
 
Stainless Steel Seamless Pipes, in accordance with the usage, there are structure use seamless pipe, fluid transfer use seamless pipe, boiler use seamless pipe, boiler use high-pressure seamless pipe, Fertilizer equipment use high pressure seamless pipe, Cold-rolling & Cold-drawing precision seamless pipe.
