| The welded steel pipe also calls the welded pipe, is with the steel plate or the steel belt after the curl formation welds steel pipe which makes. The welded steel pipe technique of production is simple, the production efficiency is high, the variety specification are many, the equipment capital are few, but the general intensity is lower than the seamless steel pipe. Since the 1930s, along with the high quality hoop tandem rolling production's rapidly expand as well as the welding and the examination technology's progress, the welded joint quality has enhanced unceasingly, welded steel pipe's variety specification increases day by day, and has replaced the seamless steel pipe in more and more domains. The welded steel pipe divides into the straight seam welded pipe and the spiral welded pipe according to welded joint's form. The straight seam welded pipe technique of production is simple, the production efficiency is high, the cost is low, the development is quick. Spiral welded pipe's intensity is generally higher than the straight seam welded pipe, can use the narrow semifinished materials production caliber big welded pipe, but may also use the similar width the semifinished materials to produce the caliber different welded pipe. But compares with the same length's straight slit-tube, the weld length increases 30~100%, moreover the output velocity is low. Therefore, compares small caliber the welded pipe to use the straight seam to weld mostly, the heavy-caliber welded pipe mostly uses the screw to weld. |
