The most common variations of submerged arc welding pipes are:LSAW (longitudinal welding), DSAW (double submerged arc welding, the weld is applied on both the inner and outer surface) and SSAW or HSAW (spiral welded pipe, generally used for water transmission and distribution but not for oil & gas API 5L Welded (ERW, LSAW, SSAW) Steel Line PipeOctal supply API 5L welded (ERW, EFW, LSAW, SSAW) steel line pipe in Gr B, X42, X46, X52, X56, X60, X65, X70, X80 PSL1, PSL2 and for sour service (NACE pipe).Line pipe brief introduction. API 5L steel line pipe is for oil and gas industries pipelines, developed for different working environments.

Click More Professional China Sawl Spiral Welded Steel Tube - SSAW Spiral steel pipe was made by steel ciol, extrusion forming under the normal temperature, take the technology of double wire and double-faced submerged-arc welded. Spiral steel pipe was mainly used in public waterworks, petrochemical industry, chemical industry, electric power industry, agricultural irrigation and urban construction etc. SSAW Steel Pipe - Threeway SteelThreeway steel has overwhelming advantages over cometiotors in manufacturing this SAWH steel pipe.We have 10 traditional one-step production lines and 1 two-step production line that enabels to produce finely pre-welded SAWH steel pipe of 360000 tons per year,and we have become the leading enterprise in this industry in virtue of large productivity and advanced technical equipment.
The 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 SSAW Steel Pipe, SAWH Steel Pipes Supplier In ChinaSSAW steel pipe can be produced in longer length (maximum length up to 50 meters) compared to LSAW steel pipes. Due to its spiral seam SSAW pipe has an accurate diameter accuracy and strength. The sizes are adjustable & can be tailored to end-users requirement . Uses of SSAW spiral welded steel pipes.

Spiral submerged arc (SSAW steel pipe) is when the tube is rolled, its advance direction has a forming angle (adjustable) with the center line of the forming tube, and it is welded while forming, and its welding seam is formed into a spiral line. The advantage is that the same specification can produce a variety of diameter specifications Steel The Difference and Use of ERW, LSAW and SSAW Steel PipeSpiral submerged arc (SSAW steel pipe) is when the tube is rolled, its advance direction has a forming angle (adjustable) with the center line of the forming tube, and it is welded while forming, and its welding seam is formed into a spiral line. The advantage is that the same specification can produce a variety of diameter specifications Steel lsaw steel pipes vs ssaw steel pipes lsaw steel pipe millDifferently, the SSAW pipe is spiral welded where the LSAW is longitudinally welded. 5) Different Application:LSAW steel pipes have been widely applied in the oil and gas pipelines, especially required large diameter and thick wall pipe with high strength and long-distance.
Spiral submerged arc (SSAW) is its forward direction and forming tube centerline hose reel molding angle (adjustable), side molding edge welding and weld them into a spiral, the advantage of the same specification to produce a variety of diameter sizes steel pipe, raw materials to adapt to a wider range, the weld can avoid the main stress force better, the disadvantage is the poor geometry of the weld length
