What is a SSAW steel pipe?_news_Alloy steel pipe,Carbon

SSAW steel pipe (spiral submerged arc welded steel pipe) is formed by spiral bending of hot-rolled strip steel,and spiral seam steel pipe (also called spiral welded pipe,spiral pipe spiral steel pipe) is formed by automatic welding of submerged arc for inner and outer joints.It can be widely used in the production of large diameter steel pipes for the following reasons:Welding of pipes - SpesmetWelding during pipe production is mainly by submerged arc welding for larger diameter pipe and by electrical resistance welding (high frequency) for smaller Electric resistance welded (ERW) pipe is manufactured by forming steel plate or Pipe are produced with outer diameterThe difference between ERW,SSAW,LSAW(UOE) Steel pipe LSAW (Large-Surface Submerged-Arc Welded Pipe) is produced by using a single medium-thickness plate as a raw material,and pressing (rolling) the steel plate into a tube blank in a mold or a molding machine,adopting a double-sided submerged arc welding method and expanding the diameter.Its product specification range is wide,the toughness,plasticity,uniformity and compactness of the weld

The difference between ERW,SSAW and LSAW

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 The difference between ERW,SSAW and LSAWSpiral 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 The difference between ERW steel pipe and spiral steel Jun 03,2018 large outer diameter erw submerged arc welding pipe#0183;Spiral steel pipe is a coiled steel pipe made from strip coils as the raw material,which is often warm extruded and welded by an automatic double wire double-sided submerged arc welding process.The strength of the spiral welded pipe is generally higher than that of the ERW welded pipe.

The difference between ERW steel pipe and spiral steel

Jun 03,2018 large outer diameter erw submerged arc welding pipe#0183;Spiral steel pipe is a coiled steel pipe made from strip coils as the raw material,which is often warm extruded and welded by an automatic double wire double-sided submerged arc welding process.The strength of the spiral welded pipe is generally higher than that of the ERW welded pipe.The Difference and Use of ERW,LSAW and SSAW Steel PipeERW is-high-frequency resistance welding-straight seam welded pipe; LSAW is-submerged arc welding-straight seam welded pipe; both belong to straight seam welded pipe,but the two have different welding processes and different uses,so they cannot represent straight seam welded pipe alone.SSAW-spiral welding-spiral welded pipe is more common.Some results are removed in response to a notice of local law requirement.For more information,please see here.Previous123456NextThe difference between ERW,SSAW,LSAW(UOE) Steel pipe

Electric resistance welded (ERW) pipe is made from steel coil and the weld seam runs parallel to the pipe.The width of the coil is the same as the circumference of the pipe so diameters are limited to 24 inches.However,because the manufacturing process is fast,it is ideal for large production runs of small ( large outer diameter erw submerged arc welding pipelt;= 24 in.) diameter sections.SSAW Steel Pipe,Spirally Submerged Arc Welded SAW (Submerged Arc Welding) Steel Pipe,Sunny Steel Submerged arc weld has high quality,high production efficiency,arc and smoke a few characteristics,submerged arcwelded pipe is widely used in pressure vessels,pipe manufacturing,beams,low pressure fluid,steel works.Size of saw steel pipe Outer Diamter 219.1mm - 4064mm (8 - 160)

Pipe Manufacturing Process Seamless and Welded Pipe

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 People also askHow are electrodes used in pipe welding?How are electrodes used in pipe welding?When the ERW steel pipe welding process,two electrodes,usually made from copper,are used to apply pressure and current.The electrodes are disc-shaped and rotate as the material passes between them.This allows the electrodes to stay in constant contact with the material to make long continuous welds.Differences Between SAW and ERW Pipe Winsteel GroupLongitudinal Submerged Arc Welding (LSAW) Processes When operational conditions require high wall thickness due to high internal or external pressures,LSAW (Longitudinal Submerged Arc Welding) pipes are commonly the most economical solution.The LSAW pipe diameter range is larger than ERW (Electric resistance welding),normally from 16 inch (406 mm) to 60 inch (1500 mm).
