ERW pipe means electric resistance welded pipe,and it is a resistance welding by 10-500 kHz of high-frequency current.The raw material of the ERW steel pipe is hot rolled steel coil made of steel billet,and the usual material is Q195,Q215,Q235,Q355 in China ERW pipe grade,which are same material with S195,S235,S355 in Europe,and SS400 in Japan.ERW Steel Pipe,China Electrical Resistance Welded Pipe ERW steel pipe is a straight seam electric resistance welded pipe,a steel pipe whose weld is parallel to the longitudinal direction of the steel pipe.It has sturdy frame which is strong enough to make sure the stable operation.And it is resistant to water,oxygen and corrosion,which is endurable with long life span.
Electric resistance welding (ERW Welded Pipe) is used to transport oil,natural gas and other vapor and liquid objects,which can meet various requirements of high and low pressure,and currently occupies a pivotal position in the field of transportation pipes in the world.The electric resistance welding pipe is manufactured by cold forming a piece of steel plate into a cylindrical shape,and
Electric Resistance Welded (ERW) Pipes.Electric Resistance Welded (ERW) Pipes are welded longitudinally manufactured from Strip / Coil and can be manufactured upto 25 OD.ERW pipe cold formed from a ribbon of steel pulled through a series of rollers and formed into a tube which is fused through a electric charge.Electric Resistance Welded (1) welded pipe from steel plate welding into the round pipe,divided into high frequency resistance welded pipe (ERW welded pipe),straight seam arc welding pipe (LSAW),spiral welded pipe.Electrical engineering with SC,can be used as water gas pipe can also be used as threading pipe,relatively thick.
Electric resistance welding at a glance.This article provides an overview of electric resistance welding (ERW).It dicusses high-frequency ERW (contact and induction) and rotary wheel contact welding (AC,DC,and square wave).It describes the differences among the processes,as well as the power supplies and weld rolls.Galvanized Steel Pipe - SHINESTAR STEEL GROUP CO.,LTD.Cold-plated seamless pipe.Cold galvanized,electric-galvanized,galvanized the amount of small,only 10-50g/m2 of its own resistance to corrosion than hot dip galvanized pipe a lot of difference.Regular galvanized pipe manufacturers,in order to ensure the quality,most do not use electric-galvanized
