lsaw steel pipe longitudinal seam submerged arc welded pipe
·SAW pipe means Submerged Arc Welded pipe.And from different weld seam,there are two saw pipes,including LSAW and SSAW.As the name suggests,SSAW has a spiral weld seam.And LSAW has a longitudinal weld seam.ERW pipe means Electric Resistance Welded pipe.Second,Different Weld Seam Between SAW and ERW PipeLSAW Steel Pipe
1.The LASW steel pipe has one longitudinal welding seam.The inner and outer welding seams are completed through one-time submerged arc welding.2.Processed with overall mechanical diameter expanding,the internal stress of the product is small and distributes evenly,which can effectively prevent stress corrosion cracking.LSAW Steel Pipe,DSAW Steel Pipe,Welded Steel Pipelongitudinal submerged arc welded steel pipe,high frequency straight seam welded pipe.Grades of LSAW Steel Pipe For pipeline API 5L GR.B,X42,X45,X50,X60,X60,X65,X70,X80.For piles ASTM A252.Sizes of LSAW Steel Pipe OD 16-72.LSAW Welded Steel Pipe Features and Manufacturing Process6.Inside weld This is done with a tandem multi-wire submerged arc welding (about four wire) on the inner part of the straight seam welded steel pipe.7.Outside Weld Outside weld is the tandem multi-wire submerged arc welding on the outer part of the LSAW steel pipe welding.8.
LSAW pipe,DSAW pipe,longitudinal welded pipe,LSAW(longitudinal Submerged Arc Welding) pipe is fromed by JCOE with one straight welded seam,the outer diameters usually from 323mm to 1420mm.When the outer diameter is 914.4mm above,it's allowed two straight welded seams.Longitudinal Submerged Arc Welding LSAW Steel PipesLSAW Steel Pipe s (longitudinal submerged arc welding) are usually the most economical solution when high wall thickness is required due to high internal or external pressure.LSAW Steel Pipe s are larger in diameter than ERW (resistance welding),typically from 16 inches (406 mm) to 60 inches (1500 mm).Longitudinally Submerged Arc Welded Steel pipes,LSAW PipesMainly as a field gathering pipe and internal high-pressure natural gas pipeline of small-caliber,long-distance pipelines for oil and gas a small number,the vast majority of long-distance pipeline is the use of high-frequency straight seam welded pipe (ERW),spiral submerged arc welded pipe (SSAW),LSAW steel pipe (LSAW) three.

The longitudinal submerged arc welding pipe you can find on the site are generally built using hot-dipped technology to prevent rusting and weakening of the structural elements.With seamless welding quality,these longitudinal submerged arc welding pipe are annealed with nitrogen protection and are polished with utter professionalism.These products are made of robust materials such as carbon steel,
The vast majority of oil and gas pipelines in the world require the use of longitudinal submerged arc welded pipes (LSAW).Canada and other western developed countries have improved the technology of spiral welded pipe (SSAW),such as pre-welding,precision welding,multi-wire welding,mechanical expansion,etc.,which are designed with reference to the LSAW steel pipe process,which shows longitudinal seam submerged arc welded steel pipe - These solid structural longitudinal seam submerged arc welded steel pipe are used for bending,de-coiling,punching,cutting,framework construction,automotive uses and many more.You can select from customized longitudinal seam submerged arc welded steel
