Description


API 5L GRb Lsaw Steel Pipe: It is a spiral seam steel pipe welded by the double-wire double-side submerged arc welding process, which takes the strip coil as the raw material and is often warm extruded. Submerged arc welded pipe features: straight seam welded pipe production process is simple, high production efficiency, low cost, rapid development. Spiral welded pipe strength is generally higher than the straight seam welded pipe can be used to produce a larger blank diameter pipe larger pipe can also use the same width of the diameter of the pipe production of different pipe.
