High pressure large diameter line steel erw welded pipeTypes and process of welding pipe-ERW,LW,CW,SAW pipes ERW including high frequency welded steel pipe (HFW) and low frequency welded steel pipe (LFW).Over time,the welds of low frequency ERW pipe was found to be susceptible to selective seam corrosion,hook cracks,and inadequate bonding of the seams,so low frequency ERW is no longer used to manufacture pipe.The high frequency process is still being used to manufacture pipe for use in new pipeline
The LSAW steel pipe is a longitudinally submerged arc welding steel pipe whose weld seam is parallel to the longitudinal direction of the steel pipe,used for oil,gas,water transmission,engineering,offshore projects.As a responsible LSAW steel pipe manufacturer in China,TOPPER provides longitudinally submerged arc welding steel pipe with simple production process,high production efficiency,low cost and highWelded steel pipes-ERW,SSAW,LASW Hebei Haihao High Welded steel pipe is formed by rolling plate and welding the seam.It is cost-effective pipe with tighter Dimensional tolerances and less weight.It is intended for conveying gas,vapor,water or other liquid in low and medium pressure ambient,such as water mains system,sewerage system,Oil and gas pipeline,fire protection service,etc.Welded vs.seamless steel pipe American Piping ProductsWhile many pipe manufacturing methods exist,the most prominent discussion in the industry compares electric resistance welded (ERW) vs.seamless (SMLS) steel pipe.Both ERW and seamless steel pipe manufacturing methods have been in use for decades; over time,the methods used to produce each have advanced.So which is better? Manufacturing welded pipe.Welded pipe starts out as a long,coiled ribbon of steel
As a result of these early problems,ERW welded pipe was generally regarded as a second-grade pipe suitable only for low pressure applications.However,prompted by a shortage of seamless pipe and the lower cost of ERW pipe,suppliers and end users directed a major effort toward improving the pipe mill quality in the 1980s.
