SMLS pipe is formed by drawing a solid billet over a piercing rod to create the hollow shell. Seamless pipe provides the most reliable pressure retaining characteristics, and is often more easily available than welded pipe.
Welded (also Electric Resistance Welded (ERW) and Electric Fusion Welded (EFW)) pipe is formed by rolling plate and welding the seam. The weld flash can be removed from the outside or inside surfaces using a scarfing blade. The weld zone can also be heat treated, so the seam is less visible. Welded pipe often has tighter dimensional tolerances than seamless, and can be cheaper if manufactured in the same quantities. Large diameter pipe (about 10 inches or greater) may be ERW, EFW or Submerged Arc Welded (SAW) pipe.
Electrical Resistance Welded Pipe(ERW)
Electrical Resistance Welded(ERW) pipe is formed into a shape by cold forming method and joined under electrodes carrying high frequency resistance welder or high frequency or medium frequency induction heating welder. The hot rolled coil edges reaching melting temperature through the resistance shown by steel to applied high electrical current, are welded together without using any filler material. ERW pipes are widely preferred especially in Oil and Gas transportation lines.
Spiral Welded Pipe(SSAW)
Spiral Welded Pipe, hot coil produced on a powerful, precision rolling hot strip mill is uncoiled, and its leading end is joined to the trailing end of preceding strip by tandem electrode submerged arc welder to form an endless strip. The forming case shapes the strip into a cylindrical shell with a spiral seam, which is welded by tandem SAW equipment first inside, and the outside.
