Production process welding square tube narrow the billet production of large diameter pipe, you can use the same width of the billet production of different diameters of pipe. However, compared with the same length of straight seam side tube, weld length of 30 to 100%, and lower production rate. Large diameter or thick welded square tube, general steel billets made directly, and small welded thin-walled pipe only need to strip soldered directly to it. And then after a simple polishing, drawing on it. Therefore, most of the smaller diameter pipe straight seam welded pipe of large diameter are mostly spiral welded.
