Large Diameter Spiral Welded Pipes Author Gautam Vinzoda, V.V.Patel, Kishan Maheshwari Publish Year Welded steel pipe distributor in China for international Large diameter erw spiral welded steel pipe Weld Steel Pipes

As a senior steel pipe manufacturer in China, we may produce and supply welded steel pipes of different specifications according to the requirements of different foreign steel purchasers. We offer metric and British standards. Often, following size range is, Wall thickness of pipe 0.7 to 5/5 Straight seam steel pipe vs spiral steel pipeHowever, compared with the straight seam pipe of the same length, the length of the welded pipe is increased by 30-100%. Because of the above reas, the production speed of the spiral steel pipe is very slow. Therefore, straight seam welding is mainly used for small diameter welded pipes . The spiral welding is mainly used for large diameter Large diameter erw spiral welded steel pipe Weld Steel Pipes

However, compared with the straight seam pipe of the same length, the weld length increases by 30% to 100%, and the production speed is low. Therefore, most of the small-diameter welded pipes are straight seam welding and most of the large -diameter welded pipes are spiral welding . Products-Galvanized ERW Steel PipeGalvanized ERW Steel Pipe Advantage. Galvanized steel pipe features a protective zinc coating that helps prevent corrosion, rust, and the buildup of mineral deposits, thereby extending the pipe s lifespan. Galvanized steel pipe is most commonly used in plumbing and other water-supply applications. Pipe Manufacturing Process

final shape of large diameter welded tubes. Large welded tubes are primarily used in oil pipelines and offshore platforms. They are actually produced by the steelmaker industry ILVA -Laminati Piani, Taranto (Italy). The production process is characterized by three phases (1) forming; (2) welding and (3) calibration.
