LSAW Steel Pipe (Longitudinally Submerged Arc Welding Pipe) Straight Seam Submerged Arc Welded Steel Pipe. UOE SAWL PIPES. Outside Diameter508mm- 1118mm (20"- 44") , straight seam welded pipe The interior longitudinal seam of the pipe is welded from the inside by fixing 4 welding heads while moving pipe and using submerged-arc welding process.
In this video, you will learn about Welded Pipe Manufacturing Process such as SAW, ERW, EFW & HFW.. Welded Pipes are manufactured from Plate or from continues Coil or strips. To manufactured welded pipe, first, Plate or coil is rolled in the circular section with the help of plate bending machine or by a roller in the case of continues process.

Straight seam steel pipe definition: Refers to the longitudinal and parallel steel pipe of the weld. It is also commonly referred to as a straight seam welded pipe or a straight seam steel pipe. The straight seam steel pipe is made by winding a long strip of certain specifications through a high frequency welding unit
LSAW Steel Pipe, DSAW Steel Pipe, Straight Seam Welded Steel Pipe, Welded Steel Pipe
The steel pipe is mainly divided into a seamless steel pipe and a welded steel pipe, and the welded pipe is formed by bending a steel plate or a steel strip and then welded.. According to the weld form, it is divided into straight welded pipe and spiral welded pipe. According to the purpose, it is divided into general welded pipe, galvanized welded pipe, blown oxygen welded pipe, wire casing , straight seam welded pipe
Alibaba, straight seam welded pipe offers 3,465 straight seam welded pipe products. About 35% of these are Steel Pipes, 1% are Stainless Steel Pipes. A wide variety of straight seam welded pipe options are available to you, such as technique, grade, and application.
However, the straight seam welded pipe may have a T-weld weld during welding, which is a major welding defect, and the straight seam welded pipe of the T-weld is more likely to crack. At this point, because of the different welding directions, the spiral welded pipe is very good to avoid this situation.
Difference between ERW, SSAW, LSAW. Steel pipe for pipe technology, can be divided into (SML), mainly as the Oilfield internal transportation pipeline and small-diameter high-pressure natural gas pipeline, used for a small number of long-distance gas pipeline, the vast majority of long-distance pipeline with Direct seam high frequency (ERW), spiral submerged arc (SSAW), LSAW three (LSAW).
Welded pipe can be manufactured in large size without any upper restriction. Welded pipe with filler material can be used in the manufacturing of long radius bends and elbow. Welded pipes are cheaper with compared to the seamless pipe and also Weak due to the weld. There are different welding methods used to weld the pipe.
Straight-weld pipes are created by bending and forming metal, which is then welded together down the length of the pipe to create a straight, longitudinal seam. Spiral-weld pipes, on the other hand, are rolled and welded according to a preferred helical angle.
Straight seam welded perforated pipe is manufactured by perforated metal sheet which is cut to desired size and then rolled and welded into a tube. It is mainly used in high pressure applications where spiral tubes can't reach the working pressure. Straight seam welded tube can be made of carbon mild steel, stainless steel and aluminum alloy. The tubes are fabricated with diverse patterns of , straight seam welded pipe
So basically stainess steel pipes are of two types seamless and welded. In the welded pipe type we have another two sub types which you call EFW and ERW. ERW i.e Electric resistance welding ERW pipe and submerged arc welding pipe significantly dif, straight seam welded pipe
Helical Welded Pipes and Longitudinal Welded Pipes. Welded line pipes enjoy a wide acceptance in oil and gas transporting market for its selection variety and relatively low cost. According to the different welding seams, welded line pipes can be further categorized into two types, the helical welded pipes and longitudinal welded pipes.
Longitudinal and spiral welded pipe is the main difference between the two different production processes, first of all, the formation of straight seam welded pipe is the first through the molding machine to form hot rolled coil, making it into a cylindrical cylindrical outer surface, and then Welding, welding using the proximity effect or under the flux layer of the arc and skin effect , straight seam welded pipe
The differences between the ERW steel pipe( straight seam resistance welding steel pipe) and LSAW steel pipe(UOE):Straight seam welded steel pipe, according to the welding process,has two kinds: high frequency electric resistance welding and submerged arc welding. UOE is short for straight seam submerged arc welding, and ERW is short for high frequency straight seam resistance welding.
The steel pipe is divided into seamless steel pipe and welded steel pipe. Among them, the commonly used welded steel pipe can be divided into three types according to the type of weld, such as high-frequency welded pipe( ERW ), straight seam submerged arc welded pipe( LSAW ) and spiral submerged arc welded pipe( SSAW).
The ERW steel pipe is also known as straight seam pipe. It is manufactured by using electric resistance welding. The weld lies inside the tube and is not visible from the outside. The tube is commonly used in low pressure fluid conveyance applications, such as the transfer of water, coal gas, air, oil, and steam.
Alibaba, straight seam welded pipe offers 1,563 straight seam welded steel pipe mill products. About 10% of these are steel pipes, 1% are stainless steel pipes. A wide variety of straight seam welded steel pipe mill options are available to you, such as 10#, q235, and a53(a,b).
These specifications cover straight-seam welded pipe intended for high temperature and / or corrosive services. Specifications A/SA312 include the requirements for manufacture of heavily cold worked pipe.. Optional supplementary requirements are provided for pipe in these specifications for inclusion in the order.

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.
Lock Seam Pipe Value-Added Services. Lock seam pipe can be welded or bolted end to end with angle rings provided by Chicago Metal. A Van Stone flange can be made by slipping an angle ring over the pipe, cutting back the seam, say, a half inch, and then flaring the ends of the pipe. The resultant seal is excellent.
Straight Seamless or Welded Pipe. The calculated bursting strength of a straight seamless or welded pipe is at least as great as the proof test pressure calculated in Section 4.3. And it shall be welded to each end of the fitting to be tested. The nominal wall of the pipe section may be larger than the thickness indicated by the assembly marking.
Steel casing pipe is a versatile product that can be used to protect a variety of types of utility and carrier pipes. At Crestwood Tubulars, we sell a variety of types and styles of pipe that can be used as steel casing including new and used straight seam steel pipe, spiral weld pipe, seamless steel pipe, and rolled and welded pipe.
Straight seam welded pipe chamfering machine is used to flat the pipe end of longitudinal welded pipes or seamless steel pipes and finish the edges. This pipe end beveling machine consists of feeding equipment, pipe clamps, knife chassis, gear, chassis and other parts.
Although the SAWL pipe performance better than other steel tube, but its high price, make capital tension to the user and step back. One, raw material and production capacity difference ERW steel is the raw material of hot rolled steel coils, SAWL pipe material is hot rolled steel plate.
Berg also produces 180,000 tons of Spiral pipe each year in its Mobile facility. Their Spiral pipe is produced using helical seams with double submerged arc welded pipes. Dura-Bond Pipe produces API straight seam DSAW pipe in diameters ranging from 24 to 42. Their large diameter pipe comes in grades up to X-80, in lengths of up to 80.
Difference between seamless and seam pipe. Seamless pipe is formed at one time during rolling. Welded steel pipes need to be welded after rolling, generally with spiral welding and straight welding. The performance seamless tube is better, and of course the price is higher.
