The difference between straight seam welded pipe unit and coiled pipe
The straight seam welded pipe unit is roll-formed with strip steel through the high-frequency welded pipe unit to gradually form the steel tube billet, and then welded into a steel pipe by high-frequency heating, scraped off the outer burr with a scraper, and then produced by shaping, sizing, straightening and sawing. Straight seam welded pipe of the required size. This is the production method of the straight seam welded pipe that everyone usually refers to now. Literally, the welded seam is a straight line. The difference between the welded steel pipe and the spiral welded pipe is that the welding seam of the spiral welded pipe is a spiral curve, but they are all welded Steel Pipe. Coiled tube is a steel plate formed into a steel tube billet by a roller machine, and then welded into a steel tube by submerged arc welding or electric welding, and then sized and shaped on other shaping equipment. Instability, low dimensional accuracy, but simple equipment and low investment. The straight seam welded pipe equipment has high efficiency, high pipe quality, high precision and good uniformity, and is the first choice for large-scale production of steel pipes.
