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 Comparison Of ERW Steel Pipe And LSAW Steel Pipe Aug 22, 2018 · The reason for this is to take care of the spiral welded pipe manufacturers in the petroleum system. In the later stage, these spiral welded pipe manufacturers all used ERW straight seam electric resistance welded steel pipe and LSAW production line, and the amount of spiral welded pipe was smaller and smaller under the same caliber.

Definition & Means of LSAW pipe Winsteel Group

Outside weld is the tandem multi-wire submerged arc welding on the outer part of the LSAW steel pipe welding. 8. Ultrasonic Testing. This test is checking outside and inside a straight seam of welded LSAW steel pipe. And also check both sides of the base material. 100% of pipes are taking ultrasonic inspection. 9. X-ray inspection. ERW, SSAW, LSAW Welded Steel PipeERW steel pipe:high-frequency straight seam resistance welded pipe, using hot-rolled wide coil as the material, through pre-bending, continuous forming, welding, heat treatment, sizing, straightening, blocking and other processes, it has a shorter weld seam than the spiral, standard High precision, uniform wall thickness, good surface quality, and high-end benefits under pressure, but the ERW, SSAW, LSAW Welded Steel PipeERW steel pipe:high-frequency straight seam resistance welded pipe, using hot-rolled wide coil as the material, through pre-bending, continuous forming, welding, heat treatment, sizing, straightening, blocking and other processes, it has a shorter weld seam than the spiral, standard High precision, uniform wall thickness, good surface quality, and high-end benefits under pressure, but the

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 Lsaw Steel Pipe (longitudinally Submerged Arc Welding Pipe LSAW Pipe (Longitudinal Submerged Arc-Welding Pipe), also called SAWL pipe. It is taking the steel plate as raw material, mold it by the molding machine, then do double-sided submerged arc welding. Through this process the LSAW steel pipe will get excellent ductility, weld toughness, uniformity, plasticity and great sealing. SSAW Steel Pipe, Spiral Submerged Arc Pipe, SAWL Steel PipeLine Pipe:API 5L PSL1/2 Line pipe Casing API 5CT/ ISO 11960 PSL1 Steel pipe for use as casing or tubing for wells of petroleum and natural gas industries Steel Pipe for Fluid Service:ASTM A53:Black and hot-hipped galvanized welded and seamless steel pipe:BS EN10217-2

Spiral Welded Pipe SAW - Incledon

Spiral pipe is welded using the submerged arc welding process with 2 internal and 2 external welding heads in a tandem configuration. Seam Tracking and Weld Control An automatic seam tracking system ensures real-time consistent weld bead positioning for both internal and outer welds. 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. Spiral pipe welding automation drives productivityA pipe mill with this design separates pipe forming from final welding, which allows the pipe to be formed and tack welded at very high speeds. As the demand for spiral pipe for the petroleum industry has increased, so has the desire for fabrication systems that can provide shorter weld cycle times, higher throughput, and reduced material

The difference between ERW steel pipe and spiral steel

Jun 03, 2018 · Spiral steel pipe is a coiled steel pipe made from strip coils as the raw material, which is often warm extruded and welded by an automatic double wire double-sided submerged arc welding process. The strength of the spiral welded pipe is generally higher than that of the ERW welded pipe. 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 Types of Oil & Gas Pipes:Seamless, ERW, LSAW Dec 20, 2018 · The two main types of LSAW pipes are the longitudinal (with a single or double straight seam weld, DSAW) and the spiral type (called, HSAW, SSAW or SAWL pipe). Therefore, the difference between DSAW vs. LSAW is that DSAW pipes have a seam weld in the inside and outside of the pipe, whereas LSAW pipes have a single seam weld on the outer surface.

API 5L Welded (ERW, LSAW, SSAW) Steel Line Pipe

Both LSAW pipe and SSAW pipe are SAW pipe (Submerged Arc Welding Steel Pipe), is manufactured by making use of a submerged arc soldering process for preparing the steel and it results in high density pipe. Owing to the flux layer, there is no
