1. Welding process From the welding process, the welding method of galvanized spiral welded pipe and galvanized straight seam steel pipe are the same, but the straight seam welded pipe inevitably has many T-shaped welds, so the occurrence of welding defects is also greatly improved. Moreover, the welding residual stress at the defect is large, which increases the possibility of cracks.Difference between helical welded pipes and longitudinal Compari of straight seam welded steel pipe and spiral As the name shows, longitudinal pipe has a straight welding seam on the pipe surface. Different from the longitudinal pipe, the welding seam of which is vertical to the axial line of the pipe, helical welded pipe is rolled and welded according to certain helical angles.Differences Between SAW and ERW Pipe Winsteel GroupLSAW pipe weld seam. And the weld seam of the SAW pipe is not flat. You will see the weld seam of the LSAW pipe and SSAW pipe is higher than the steel plate. And the tolerance of weld seam height specified in specifications. If compare ERW pipes with SAW pipes, ERW pipes surface quality is better. ERW pipes are smooth and have a better finish.

In the SAW welding process, external filler metal (wire electrodes) are used to join the formed plates. SAW pipes can have a single longitudinal seam of double longitudinal seam depend on the size of the pipe. SAW pipes are also available in the spiral seam, which is continually rolled from the single plate coil.erw steel pipeerw pipe sizeserw pipe millerw pipe standard sizeserw pipe weighterw pipe size chartLSAW, SSAW, and ERW Pipes Description and CompariMay 06, 2020LSAW Pipes has two types Longitudinal (Single or Double Straight-seam Weld, DSAW) and Spiral (also called SSAW, HSAW, or SAWL). What makes DSAW pipes differ from other LSAW pipes is that DSAW have a seam weld in the inside and outside of the pipe, while the latter have a single seam weld on the outer surface, longitudinal or cross sectional.

Sep 19, 2019Welded steel pipes need to be welded after rolling, and generally have spiral welding and straight welding. Performance seamless pipe is better, of course, the price is also high - some.

Jun 03, 2018Spiral submerged arc welded pipe spiral weld distribution, long weld, especially in the dynamic conditions of welding, the weld is too late to leave the molding point of cooling, easy to produce welding hot cracks. The direction of the crack is parallel to the weld and is at a certain angle to the axis of the steel tube, typically between 30-70°.The strength of the spiral welded pipe is generally higherthan straight seam welded pipe,and can adopt a narrow billet to produce larger diameter welded pipes,and it can also use the billet with the same width to produce the different pipe diameter welded pipe.The Difference Between the Straight Seam Welded Pipe anWas this helpful?People also askWhat kind of pipe is straight seam welded?What kind of pipe is straight seam welded?Straight seam welded pipe. Straight seam welded pipe is made of steel plate or steel strip after bending forming, and then through welding. Divided into the form of the weld seam welded pipe and spiral welded pipe by the welding forming method.The Difference Between the Straight Seam Welded Pipe and the GeneraTypes of Oil & Gas Pipes Seamless, ERW, LSAW Compari of straight seam welded steel pipe and spiral The two main types of LSAW pipes are the longitudinal (with a single or double straight seam weld, DSAW) and the spiral type (called, HSAW, SSAW or SAWL pipe). Therefore, the difference between DSAW vs. LSAW is that DSAW pipes have a seam weld in the inside and outside of the pipe, whereas LSAW pipes have a single seam weld on the outer surface.
