ERW Longitudinal advanced product performance in the field of oil and gas storage and transportation, quality leadership, more economical steel pipe. SAW steel pipes is short of Submerged Arc Welding Steel Pipe, which it is a use of submerged arc soldering process to manufacture steel, the process produces a very high current density, the flux layer to prevent the rapid loss of heat, and concentrated in the welding
Differences between High Frequency Resistance Welded Pipe Using hot-rolled wide strip steel coils as raw materials, through pre-bending, continuous forming, welding, heat treatment, sizing, straightening, cutting and other processes, compared with spiral welded pipes, it has shorter weld seams, high dimensional accuracy, uniform wall thickness and surface quality good, with the advantages of high pressure, but the disadvantage is that only small and medium-caliber thin-walled pipes
Longitudinal Submerged Arc Welding (LSAW) Processes In LSAW pipe mills, processing is carried out by cold forming heavy carbon steel plates, the pipe prematerial on which many of the pipe properties depend. The material of LSAW steel pipe is unit middle or heavy thickness sheet, coiled in the molding or forming machine, welded by double submerged arc welding and expand the diameter.
In a Spiral SAW pipe, steel plate from the de-coiler is formed in a spiral loop. This spiral loop is then welded from inside and outside of the pipe. Because of the method of manufacture, a wide variety of diameters can be produced. Spiral saw pipes are used for low-pressure services.

Types and process of welding pipe-ERW,LW,CW,SAW pipes Spiral submerged arc welding (SSAW) steel pipe,also called HSAW pipe,welding line shape like a helix.It is using the same welding technology of Submerged Arc-Welding with LSAW pipe.Differently SSAW pipe is spiral welded where the LSAW is longitudinally welded.Manufacturing process is rolling the steel strip,to make the rolling direction have an angle with the direction of the pipe center,forming and welding, so the welding seam is in a spiral line.The SSAW pipe
