Large Diameter Welded Pipe Size And Manufacturing Process

Large diameter welded pipe typically refers to steel pipes with a diameter of 24 inches or greater. These pipes are typically used for oil and gas transmission, water supply, and other industrial applications.

The manufacturing process for large diameter welded pipes involves several steps. First, the steel coil is unwound and flattened to form a flat sheet. The edges of the sheet are then heated and pressed together to form a longitudinal seam. This seam is then welded using various welding techniques such as electric resistance welding (ERW) or submerged arc welding (SAW).

After welding, the pipe is then passed through a series of rollers to shape it into the desired diameter. The pipe is then cut to the required length and undergoes various quality control tests before being coated and prepared for shipment.

Overall, the manufacturing process for large diameter welded pipes is a complex and precise operation that requires advanced equipment and skilled labor to produce high-quality pipes that meet industry standards.
