The difference between coiled tubing and welded tubing

　　Straight seam welded pipe is formed by strip forming of high-frequency welded pipe by strip steel, gradually forming steel pipe billet, then welding into steel pipe by high-frequency heating, scraping the outer burr by scraper, and finally producing the required shape by straightening and straightening sawing The size of the straight seam welded pipe. This is what we usually call the production of straight seam welded pipe. It is literally explained that the weld is a straight line. The difference between a welded steel pipe and a spiral welded pipe is that the weld of the spiral welded pipe is a spiral curve, but they are all welded. Steel Pipe.

　　The coiled tube is a steel sheet formed by a steel plate through a roller machine, and then welded into a steel pipe by submerged arc welding or electric welding, and then sizing to other shaping equipment. This tube is low in efficiency and the quality of the tube is small. Unstable, low dimensional accuracy, but less investment in equipment. The straight seam welded pipe equipment has high efficiency, high pipe quality, high precision and good uniformity.
