API 5L Welded (ERW, LSAW, SSAW) Steel Line Pipe

Spiral Welded Line Pipe (SSAW Pipe) API 5L X60 Octal is located in China recognized as a leading supplier, distributor, and manufacturer union in providing piping solutions for oil and gas company. Product ranges in Steel Pipe, Casing and Tubing, Steel Plate, Sucker Rod, Steel Pipe Fittings, Valves, and Equipment for pipelines. China Longitudinal Weld ERW, Saw, Dsaw, Efw Steel Pipes Longitudinal Weld ERW, Saw, Dsaw, Efw Steel Pipes. Spiral welded steel pipe refers to the steel belt or steel plate bending deformation into the shape of round, square, and then welded into the surface of the joint steel pipe.According to different welding methods can be divided into arc welding pipe, high frequency or low frequency resistance

Difference between ERW, HFW, SAW and EFW pipe www

Jun 03, 2021 · Electric Fusion Welding (EFW) steel pipe refers to an electron beam welding, the use of the high-speed movement of the electron beam directed impact kinetic energy is converted to heat the workpiece so that the workpiece leaving the melt, the formation of the weld. It is mainly used for welding dissimilar steel welding sheets or which high power density, metal weldment can rapidly heat to high EFW pipe vs SSAW pipe - Sunny SteelEFW pipe vs SSAW pipe ERW - Electric Resistance Welded. For pipes or tubes size 4 inch (10.2mm) OD and below, strip is fed into a set of forming rolls which consists of horizontal and vertical rollers so placed as to gradually from the flat strip in to a tube which is then allowed to pass the welding electrodes.

LSAW, SSAW, and ERW Pipes Description and

May 06, 2020 · May 06, 2020 · SSAW pipe takes form by rolling and welding a steel strip in a way that the pivotal direction is oblique to the axis or pipe center, making the weld seam in a spiral line. LSAW pipes are produced by molding steel sheets to a cylinder and joining the ends together by welding in a straight line. LSAW Pipe Forming. The Difference and Use of ERW, LSAW and SSAW Steel PipeJul 01, 2020 · Jul 01, 2020 · Spiral submerged arc (SSAW steel pipe) is when the tube is rolled, its advance direction has a forming angle (adjustable) with the center line of the forming tube, and it is welded while forming, and its welding seam is formed into a spiral line. The advantage is that the same specification can produce a variety of diameter specifications Steel pipe, the raw material adapts to a larger range, the weld

What is The Differences Between LSAW Pipe and SSAW

Differently SSAW pipe is spiral welded where the LSAW is longitudinally welded. Manufacturing process is rolling the steel strip, to make the rolling direction have an angle with the direction of the pipe center, forming and welding, so the welding seam is in a spiral line. SSAW pipe (HSAW Pipe) Size range and Features Difference between ERW, SSAW, LSAW - Sunny SteelSpiral submerged arc (SSAW) is its forward direction and forming tube centerline hose reel molding angle (adjustable), side molding edge welding and weld them into a spiral, the advantage of the same specification to produce a variety of diameter sizes steel pipe, raw materials to adapt to a wider range, the weld can avoid the main stress force better, the disadvantage is the poor geometry of the weld length compared to the long straight seam pipe, prone to cracking, porosity, slag, welding
