Aug 22, 2018 · The welded steel pipes are mainly divided into three processes:straight seam electric resistance welding (ERW), spiral submerged arc welding (SSAW) and straight seam submerged arc welding (LSAW). . The welded pipes produced by these three processes have their own positioning in the application field due to their different raw materials, molding process, caliber size and quality, and Comparison of Characteristics between ERW Steel Pipe and Straight seam electric resistance welded steel pipe and spiral submerged arc welded steel pipe can better meet the requirements of oil and natural gas transmission pipelines.For steel pipes of medium caliber (630mm), ERW steel pipes are mostly used abroad. Spiral submerged arc welded pipes are generally only used for low-pressure fluid transmission, civil buildings, structures and pile
Steel pipe for pipe technology, can be divided into (SML), mainly as the Oilfield internal transportation pipeline and small-diameter high-pressure natural gas pipeline, used for a small number of long-distance gas pipeline, the vast majority of long-distance pipeline with Direct seam high frequency (ERW), spiral submerged arc (SSAW), LSAW three (LSAW).

SAW- Submerged Arc Welding (Long seam & Spiral Seam) ERW Steel Pipe Manufacturing Process In the ERW / EFW / HFW pipe process, the first plate is formed in a cylindrical shape and the longitudinal edges of the cylinder formed are welded by flash-welding, low-frequency resistance-welding, high-frequency induction welding, or high-frequency Products, ERW DSAW SMLS pipe Weiler Pipe llc.DSAW Pipe is distinguishable by the spiral DSAW seam that runs the length of the pipe up to 155 feet. Advantages:The submerged welding process protects the steel from the contamination of air impurities. The welds also penetrate 100% of the pipe wall, producing a very strong bond. SSAW Steel Pipe - Threeway SteelDescription & Specification. Spiral Submerged- Arc Welded Steel Pipe. Brief overview:SSAW steel pipeSpiral Submerged- Arc Welded Steel Pipe is also known as the SAWH Steel pipe (Submerged-arc Welded Helical pipe. Generally used:welded pipes convey fluid, metal structures, pile and so on.
Threeway steel has overwhelming advantages over cometiotors in manufacturing this SAWH steel pipe.We have 10 traditional one-step production lines and 1 two-step production line that enabels to produce finely pre-welded SAWH steel pipe of 360000 tons per year,and we have become the leading enterprise in this industry in virtue of large productivity and advanced technical equipment. Spiral Welded Pipe - Nucor SkylineSpiralweld pipe is manufactured from steel coil and typically utilizes a helical double submerged arc weld (DSAW). The mill setup offers avarying degree of flexibility, allowing for production of a wide range of pipe diameters and wall thicknesses. Spirally Welded Steel Pipes - Production - HatboruSpirally Welded Steel Pipes Step 1 Hot rolled steel sheets are subjected to required measurement control as well as mechanical and chemical testing to ensure compliance with the applicable standards followed by sheet number and sheet acceptance labeling before being transferred to the stockyard.
Both the seams are welded from inside and outside of the pipe. In the case of high thickness pipe, multiple pass welding is done. In a spiral saw pipe, steel plate from the de-coiler is formed in a spiral loop. This spiral loop is then welded from inside and outside of the pipe. The Difference Between Straight Seam Steel Pipe and Spiral Compared with straight seam steel pipes, spiral steel pipes have certain advantages in strength. The main process of producing spiral steel pipe is submerged arc welding. Spiral steel pipes can be used to produce welded pipes of different pipe diameters from blanks of the same width. The Difference Between the Straight Seam - East Steel PipeSpiral pipe is used in industry, also known as spiral steel pipe or spiral welded pipe, and it is to roll the low carbon structural steel and low alloy steel strip to tube according to certain helix angle, and then welded pipe joints. Let me introduce you the characteristics and the usage of the spiral pipe.
