Large-diameter pipe may be ERW, EFW or Submerged Arc Welded ("SAW") pipe. The two types of pipes produced through ERW technologies are Longitudinal submerged arc welded (LSAW) and Spiral submerged arc welded (SSAW) pipes. LSAW are made by bending and welding wide steel plates and most commonly used in oil and gas industry applications.

LSAW and SSAW both in submerged arc welding, LSAW pipe usually refer to pipe diameter from 16” to 56” (406.4 mm to 1422 mm), SSAW pipe OD is from 16” to 100 ”. (406.4 mm to 2540 mm) Product specification level of Grade B pipe. Same with API 5L Gr. B seamless pipe, the welded type also have PSL 1 and PSL 2 two product specification level.
Difference between saw and erw pipe. First, difference between the production process. ERW pipe is the hot-rolled coil through the continuous roll forming, the use of high-frequency current skin effect and proximity effects, so that the plate edge of the hot melt, squeezing the roller pressure to the role of pressure welding achieve production.
Difference between erw and saw steel pipe is also known as soft steel, the carbon content is from 0.10 to .30% and easily accepted by various processing such as forging, welding and cutting, commonly used in the manufacturing chain, rivets, bolts, shafts, etc.

Welded pipes are cheaper with compared to the seamless pipe and also Weak due to the weld. There are different welding methods used to weld the pipe. ERW- Electric Resistance Welding; EFW- Electric Fusion Welding; HFW- High-frequency welding; SAW- Submerged Arc Welding (Long seam & Spiral Seam) ERW Steel Pipe Manufacturing Process
Difference between ERW, SSAW, LSAW. Steel pipe for pipe technology, can be divided into (SML), mainly as the Oilfield internal transportation pipeline and small-diameter high-pressure natural gas pipeline, used for a small number of long-distance gas pipeline, the vast majority of long-distance pipeline with Direct seam high frequency (ERW), spiral submerged arc (SSAW), LSAW three (LSAW).
