results for this questionFeedbackDifference between erw and saw steel pipe,Sunny Steel

Difference between erw and saw steel pipe is also known as soft steel,the carbon content is from 0.10 to .30% and easily accepted by various processing such as forging,welding and cutting,commonly used in the manufacturing chain,rivets,bolts,shafts,etc. results for this questionWhat is ERW pipe welding?What is ERW pipe welding?ERW steel pipe is manufactured through low or high frequency resistances Electric Resistance.Welding seam is in longitudinal.During the ERW pipe welding processes,the electric current will make the heat when flow through the contact surface of the welding area.It will heat the 2 edges of the steel to a point that the edges can form a bond.Petrosadid Electric Resistance/ Fusion Welded (ERW and EFW) results for this questionWhat is the difference between longitudinal and helical welding?What is the difference between longitudinal and helical welding?Therefore,compared to longitudinal welded pipes,the helical pipe,with lower sustained stress,can guarantee more safety and longer service of life.As for longitudinal welding,the width of the steel plate should be strictly stuck to the diameter of the pipe.Difference between helical welded pipes and longitudinal welded pipes

Welded Carbon Steel Pipe - ERW DSAW Carbon Steel Pipes

Welded Carbon Pipe.Worldwide Pipe Supply stocks and supplies a complete inventory of welded carbon steel pipe including ERW (Electric Resistance Welded) and DSAW (Double-Submerged Arc Welded) steel pipes,ranging in size from 1/8 inch to 60 inch OD.Along with commodity grades and sizes,we can supply many odd-ball hard-to-find sizes.What is EFW steel pipe - pipelinedubaiWhat is EFW steel pipe? EFW steel pipe (Electric Fusion Welding steel pipe) refers to an electron beam welding,the use of 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.EFW steel pipe is formed by rolling plate and welding the seam.What is The Differences Between LSAW Pipe and SSAW PipeLSAW Pipe (Longitudinal Submerged Arc-Welding Pipe),also called SAWL pipe.It is taking the steel plate as raw material,mold it by the molding machine,then do double-sided submerged arc welding.Through this process the LSAW steel pipe will get excellent ductility,weld toughness,uniformity,plasticity and great sealing.

What is The Differences Between LSAW Pipe and SSAW Pipe

The SSAW pipe diameter range is from 20 inch to 100 inch,406 mm to 2540 mm.The advantage part is we can get the different diameter of SSAW pipes with the same size of the steel strip,there is a wide application for the raw material steel strip,and welding seam should avoid the primary stress,good performances to bear the stress.What is a Welded Steel Pipe? About Welded or ERW Steel Welded pipe (pipe manufactured with a weld) is a tubular product made out of flat plates,known as skelp that are formed,bent and prepared for welding.The most popular process for large diameter pipe uses a longitudinal seam weld.Spiral welded pipe is an alternative process,spiral weld construction allows large diameter pipe to be produced from narrower plates or skelp.
