LSAW Steel Pipe,DSAW Steel Pipe,Welded Steel Pipe

Straight seam welded steel pipe (lsaw steel pipe),Double-sided submerged arc welding steel pipe (dsaw steel pipe),longitudinal submerged arc welded steel pipe,high frequency straight seam welded pipe.Grades of LSAW Steel Pipe For pipeline API 5L GR.B,X42,X45,X50,X60,X60,X65,X70,X80.For piles ASTM A252.Sizes of LSAW Steel Pipe:Pipe SSAW pipe full name is Spiral Submerged arc welding pipe.The pipe is formed by spiral submerged arc welding technology which is called SSAW pipe.Generally speaking,when it comes to the same standard and steel grade,the price of SSAW pipe is cheaper or lower than ERW pipe and LSAW pipe.The strength is higher than the straight seam welded pipe.Some results are removed in response to a notice of local law requirement.For more information,please see here.12345Next
