Xining by stainless steel pipe have high quality products and good service, and market reputation, praised by users. Users are welcome to co-operate. We will be happy to serve you, Qinghai stainless steel pipe used in all the most advanced molding methods, reasonable structure, advanced technology. Xining stainless steel pipe widely in national production and construction applications, straight seam steel pipes and spiral due to the different production processes and therefore has many differences, Qinghai stainless steel pipe production process is relatively simple, the main production process is high-frequency straight seam welded steel pipe and submerged straight seam steel pipe, straight seam pipe high efficiency, low cost, rapid development. Xining stainless steel pipe industry production during a large-caliber straight seam steel pipe welding technology uses T, is about a short straight section of pipe joints butt again, then a chance of compliance with engineering required length, straight seam welded steel pipe defect T has greatly improved, T welds and weld residual stress is large, the weld metal are often in three-dimensional stress state, increases the likelihood of cracks, product performance fully meet the standard requirements, guarantee to provide customers with products and services.
