Oil pipe production process

　　API 5L X42 Oil Carbon Seamless Steel Pipe is a steel pipe with longitudinal seam parallel to steel pipe. Usually divided into metric welded pipe, welded thin-walled tube, transformer cooling tubing and so on. Longitudinal welded pipe production technology is simple, high production efficiency, low cost, to production faster. Spiral steel pipe is strip coil as raw material, regular temperature kneading molding, active double wire double-sided submerged arc welding technology made of spiral seam pipe.
