LSAW steel pipe ,also know as Longitudinal Submerged-Arc Welded Steel Pipe ,is made under the requirements of american petroleum institute standard (api).LSAW pipes could be used for large pipeline project ,water gas project ,city pipeline and so on .

 

 

ERW steel pipe is the most cost-efficient pipe :

1, cheaper than seamless steel pipe ,but nearly strong .

2, no filler metal ,the seam is the same as parental metal ,better than LSAW .

3, the seam is shorter than SSAW .
