Welding of Large Diameter Pipelines Design,Processes

Weld After Backfill is a sequence used to improve overall installation rate for steel pipe. Pipe is laid and welded outside (if required). Joint coating is applied,usually a shrink sleeve or mortar diaper. Pipe is backfilled. The inside weld is made later.Tianjin Youfa large diameter spiral steel pipe SSAW Steel 4.Hydropower station pipe (Hydraulic Pipe); 6.YouFa SSAW spiral welded steel pipes,which with Large diameter and strong supply ability are widely used in construction and fluid transportation.Note 1.Free sampling; 2.Large diameter; 3.API 5L,ISO certified; 4.100% after-sales quality assurance.5.Spiral Welded Steel Pipe Philippines SSAW/HSAW Pipe Spiral welded steel pipe is a low carbon carbon structural steel or a low alloy structural steel strip rolled into a tube blank with a certain helix angle (also called forming angle),and then welded and made into a pipe joint,which can use a narrow strip steel production of large diameter steel pipes..Spiral welded pipes are single-sided welded and double-sided welded.

Sale Production process of large diameter welded pipe

Large-diameter welded pipe is a spiral seam steel pipe,which is made of strip steel coil as raw material,often formed by warm extrusion,and welded by automatic double-wire and double-sided submerged arc welding process.The spiral steel pipe sends the strip steel into the welding pipe unit.SSAW Steel Pipe,Spirally Submerged Arc Welded - LandeeWelded Steel Pipe (39) LSAW Pipe (18) SSAW Pipe (7) ERW Pipe (10) Seamless Steel Pipe (112) Cold Drawn Seamless Pipe (13) Hot Rolled Seamless Pipe (16) Hot Expanded Seamless Pipe (6) Precision Seamless Pipe (16) Large Diameter Thick-Walled (6) OCTG Pipe (34) OCTG Tubing (4) OCTG Casing (8) OCTG Drilled Pipe (15) OCTG Sucker Rod (7) Surface SSAW Steel Pipe vs.LSAW Steel Pipe - ESC GroupThe difference is SSAW pipes are welded in the helix or spiral position while LSAW pipes are welded in the longitudinal direction.Manufacturing process of SSAW pipe is by rolling and welding a steel strip in a way that the pivotal direction is oblique to the axis or pipe center,making the weld seam in a spiral line.
