Spiral Submerged Arc Welded Pipe - Spiral Welded Pipe

Aug 17, 2019 · Spiral submerged arc welded pipe is also called spiral welded steel pipe or spiral welded pipe which is formed by spiral bending of hot-rolled strip steel. Spiral submerged arc welded pipe manufacturing process is taking steel strip coil as raw material, through normal temperature extrusion molding, welded by automatic double wire double-sided submerged arc welding machine. Spiral Submerged Arc Welding Services - Spiral Arc Welding Spiral Arc Welding Services. We offer spiral arc welding, also known as spiral submerged arc welding. In this welding process, the material is submerged under a bed of fusible flex, which becomes conductive when heated. The resulting weld is sound, uniform and corrosion resistant, with a spiral submerged arc welding steel pipe For heavy Duty spiral submerged arc welding steel pipe that come in distant varieties, sizes, material quality Development of High Speed Submerged Arc Welding in The high speed welding in the spiral welding proc-ess was realized by the studies as follows; 1) studies of welding conditions such as current, arc voltage, electrode position and spacing 2) development of flux for high speed welding.

Introduction of our company 2. Introduction of Product 1) Image 2) Product's description in detail Process:Spiral Submerged- Arc Welded Steel Pipe Usage:Used for low pressure pquid transportation, such as water, gas, and oil; construction and pipng Standard:API 5L, ASTM A252, EN10217-1,2,5, EN10219-1, BS, JIS, IS SSAW Steel Pipe - Threeway SteelThe SAWH steel pipe is the spiral submerged arc welding steel pipe for short. It is made adopting sumberged arc welding technique and comes with a welding seam. 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 Spiral Steel Pipe - East Steel PipeDescription. Spiral steel pipes are made by steel coil, extrusion forming under the normal temperature, then taken the technology of double wire and double-faced submerged-arc welded. During molding process of spiral welded steel pipe, steel plate has uniform deformation and light residual stress, thus the surface has no scratches. The difference between ERW, SSAW and LSAW - United SteelJan 10, 2018 · Spiral submerged arc (SSAW) is the direction of rolling and forming tube center line forming angle (adjustable), side molding and welding, the welding seam of the spiral line, has the advantages of steel pipe of the same specifications can produce a variety of diameter specifications, raw materials to a large range, the weld can avoid stress Spiral submerged arc welding (SSAW) steel pipes ASTM As we know,seamless steel pipe always is small dimension,longitudinal submerge arc weld steel pipe is large dimension,but for larger dimension,we should use the method of spiral submerge arc welding instead of longitudinal submerge arc welding.With this method,we can use narrow width steel plates to produce large dimension pipes.The outside diameter is determined by the angle of the de-coiled Submerged Arc Welding - an overview ScienceDirect TopicsJan 09, 1993 · For this welding process, Hashemi et al. (20) studied the hardness and the microstructure of the fusion zone, the base metal, and the HAZ of double submerged arc welded (SAW welding) in a line pipe steel of grade API X65 manufactured and welded by spiral forming. The hardness of the FZ was slightly higher than the hardness of the base metal and Definition and advantages of hsaw pipe - Welded Steel Pipe Dec 15, 2017 · Helical submerged arc welding (spiral) steel pipe is the full name of hsaw pipe, to the strip into the welded pipe unit, the multi-roll rolling, the strip gradually rolled up to form a circular tube with an open gap, adjust the reduction of squeezing roller so that the weld gap control in 1 ~ 3mm, and make both ends of the weld flush.Spiral welded pipe is formed by forming the material strip SSAW Steel Pipe - SHINESTAR STEEL GROUP CO., LTD.SY/T5037 Spiral submerged arc-welded steel pipe for pipelines for low pressure field fluid service.
