In the process of production, machining, welding, testing and heat treatment of seamless steel pipes, the surface area of seamless steel pipes (carbon copper pipes, stainless steel pipes) will accumulate iron oxide, welding slag, grease and other dirt, making the seamless steel pipe resistant to Corrosion performance becomes stronger.
Read morePrecision steel pipe is a product that has appeared in recent years. The main feature is that the inner hole and outer wall dimensions have strict tolerances and roughness.
Read moreStraight seam welded steel pipe is mainly used in water supply engineering, petrochemical industry, chemical industry, electric power industry, agricultural irrigation and urban construction.
Read moreProduction process of spiral seam submerged arc welded steel pipe
Read moremost of the smaller diameter welded pipes adopt straight seam welding, and the large diameter welded pipes mostly adopt spiral welding.
Read moreThe purpose of anti-corrosion of seamless steel pipes for low and medium pressure boilers is to prolong the service life of the steel pipes themselves. Especially when it is used in underground industrial pipelines, oil and gas transportation, high-quality water pipelines and other projects, anti-corrosion treatment is required.
