LSAW (Large-Surface Submerged-Arc Welded Pipe) is produced by using a single medium-thickness plate as a raw material,and pressing (rolling) the steel plate into a tube blank in a mold or a molding machine,adopting a double-sided submerged arc welding method and expanding the diameter.Its product specification range is wide,the toughness,plasticity,uniformity and compactness of the weld results for this questionWhat is SSAW pipe?What is SSAW pipe?SSAW Pipe (Spiral Submerged Arc-Welding 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.What is The Differences Between LSAW Pipe and SSAW Pipe results for this questionWhat kind of steel is used for LSAW?What kind of steel is used for LSAW?LSAW (Longitudinally Submerged Arc Welded Steel pipes) in leaflets plate as raw material,the steel plate in the mold or molding machine pressure (volume) into using double-sided submerged arc welding and flaring from production.Low-temperature resistance can only use one HS code to declare the pipe fitting.Longitudinally Submerged Arc Welded Steel pipes,LSAW
At present,it is widely used in the field of urban gas,crude oil,finished oil transportation,etc..SSAW steel pipe,spiral submerged arc welded pipe is coiled its forward direction and shaping of the center line of the pipe forming angle (adjustable),side shaping welding edge,the weld into spiral line,the advantage of the same specifications can produce a variety of diameter specifications of steel,rawLSAW Steel Pipe ASTM 53API 5L - Threeway Steel Co.,LtdLSAW Steel Pipe Pipe Type Welded steel pipeDSAW steel pipeSAW steel pipeSAWL steel pipe Application used for low pressure liquid delivery,such as water,gas,and oil Specification OD:323.9mm -1820mm(12''-72'')
May 06,2020·The welding line of LSAW pipe is around 60% lesser than of SSAW pipes.Using steel plates,quality of LSAW pipe can be tested by non-destructive procedures.While SSAW pipes using hot-rolled coils should be tested with destructive methods such as x-ray.LSAW pipes adopt welding after molding process where various checks can take place.Lsaw Steel Pipe With Coating,Lsaw Steel Pipe With Coating offers 2,138 lsaw steel pipe with coating products.About 99% of these are steel pipes,1% are stainless steel pipes.A wide variety of lsaw steel pipe with coating options are available to you,such as 10#,a53(a,b),and 16mn.Piling Pipe,Big Size LSAW Steel Pipe,Low Carbon SSAW As a professional piling pipe supplier,we can supply high quality big size LSAW steel pipe and low carbon SSAW spiral pipe.Our products are efficient,cost effective and deliver more benefits.Welcome to

·The most common welding technique used for oil and gas pipes is the so-called high-frequency induction technology (ERW-HFI),consisting in the application of an induction current on the outer surface of the pipe able to generate a robust seam weld and join the two sides of the steelWelded steel pipes-ERW,SSAW,LASW Hebei Haihao High Welded steel pipe is formed by rolling plate and welding the seam.It is cost-effective pipe with tighter Dimensional tolerances and less weight.It is intended for conveying gas,vapor,water or other liquid in low and medium pressure ambient,such as water mains system,sewerage system,Oil and gas pipeline,fire protection service,etc.What is The Differences Between LSAW Pipe and SSAW PipeLSAW 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.
