Welded Large Diameter Pipe
Wall thickness: 219.1mm~3020mm
Shape: Round
Technology: Hot Rolled
Large diameter welded pipe generally use double-sided submerged arc welding process, is the nominal diameter of DN200 (8-inch pipe) - DN600 (24-inch pipe) large caliber specifications of the welded pipe, large diameter spiral welded pipe production cost is high, low production efficiency, but the spiral of the weld seam has a higher compressive strength, to ensure that the large diameter of the welded pipe compressive capacity. If your project requires a large diameter pipe with strong pressure resistance, you can choose large diameter spiral welded pipe.
