Seamless Pipe
The product adopts high-quality coiled plate ,after re-examination cut vertically or strip coil to shaping automatically and melting .Getting rid of burrs inside and outside the pipe , while the computer control the best melting temperature . The qualified steel pipe after the non-destructive inspection in the seldom oxidize environment , wholly hot to 850℃ then take out of the furnace . Get rid of the phosphorus, through tension reduce machine hot-rolling several times, which make metallographic organization grain state size of geometry and mechanical performance average. Our products carry out API Spec 5L, API Spec 5CT, GB/T8163-1999 standard. Our products are widely used in flammable and non-flammable fluid transferring pipe and boiler and steel construction. It has filled the domestic gaps.
