Applications of SSAW Pipe:Second, we should know the application of SSAW Steel Pipe. Spirally Submerged Arc Welding pipes use in oil, natural gas, water and other flammable & nonflammable liquid conveying and distribution pipelines. At the same time, it can use in structures for construction and other general purposes due to the wide size range. A/SA333 pipe welding procedure - American Welding SocietyOct 12, 2005 · The first one, we used 6" sch 40s pipe (.280" nom.) A/SA333 Grade 6 using GTAW with a maximum heat input of 38Kj per inch (Seemed very high to me but) in the 6G position. My HAZ impacts were between a low of 128 and a high of 143 foot pounds at -50 degrees F. My weld metal imacts were between a low of 89 and a high of 143 foot pounds impact.
Metline is a specialized manufacturer and factory supplier of Spiral Welded Pipes, also known as Spiral Submerged Arc Welded Steel Pipes (SSAW Pipes), widely used in the Oil and Gas, Petrochemical, Agricultural and Construction Industries. We can supply high quality SSAW pipes with various standards, including but not limited to API 5L GR A, GR B, X42, Difference between ERW, SSAW, LSAW - Sunny SteelSpiral 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 Difference between erw and saw steel pipe, Sunny Steel Saw steel pipe with solvent deposited, more types of defects, in addition to volume defects, there are wire-line trap. ERW steel pipe weld defects only wire-line and straight welds, the inspection process easy to follow, and the defects in the maximum reflection at, once the lack of implicit, ultrasonic reflecting the strong, easy to detect. (3) ERW steel pipe related to saw steel pipe in residual stress ratio is low.
Longitudinally Submerged Arc Welded Steel pipes . 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. SSAW Interlocked Pipe Piles with Extra Long Size - Buy Product Description. SSAW Pipe Pile. Spiral welded pipe is made by rolling a low-carbon carbon structural steel or a low-alloy structural steel strip into a tube blank at a certain spiral angle, then welding the pipe seam. SSAW Steel Pipe, Spiral Submerged Arc Pipe, SAWL Steel PipeLine 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
The annual yield of SSAW pipe with outside diameter 219mm-3620mm, wall thickness 5-25.4mm and steel grade B-X80 is 1,000,000 tons. its two steel pipe production lines, one for spiral submerged arc welded (SAW) steel pipe and one for longitudinal submerged arc welded (SAW) steel pipe, are respectively comprised of two sets of main machines and 1 SSAW Steel PipeThreeway 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.

ERW steel pipe related to saw steel pipe in residual stress ratio is low. Since ERW pipe deformation in the deformation process more fully, coupled subsequent sizing flat oval, elliptical vertical changes and necking, making ERW pipe residual stress becomes smaller. 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 Weld pipes ERW LSAW SSAW welded pipesSSAW Pipe,Spirally Submerged Arc Welding Pipe, Sprial Steel Pipe :Application:Oil / Gas / Water transmission, Construction & Structure Parts:Size:OD:219mm-4064mm WT:3.2-40mm LSAW pipe,Longitudinally Submerged Arc Welding Pipe :Application:Oil / gas / water Transmission, Engineering / Offshore projects:Size:OD:219mm-1625mm
Welding Carobn Steel Plate and Pipe by SMAW Process 1. Scope. 1.1 This article is about the requirements for welding carbon steel between 1 mm and 19 mm (1/16 in and 3/4 in) thick plate and pipe in all positions by Shielded Metal Arc Welding (SMAW) process using F No. 1, 2, 3, and 4 electrodes with either open butt or backing rings, to assure Welding Pressure Pipeliners and Piping SystemsWelding (SMAW) and double ending pipe using automatic welding. Lincoln Electric supplies electrodes, power sources, automatic and semiautomatic wire feeders, submerged arc wire and flux, which are the industry standards for pipeline construction around the world. Semiautomatic, self-shielded flux-cored Innershield® Process is being used around What are differences between SAW pipes and ERW pipes Haihao Group could provide many kinds of pipes made by carbon steel,stainless steel and alloy steel like weld steel pipe and seamless steel pipe.And at first in welded steel pipe,you will find different methods of forming process, such as ERW,LSAW,SSAW.So lets talk about the differences between SAW pipes and ERW pipe.
SSAW Steel Pipe. SSAW Steel Pipe:It is a spiral submerged arc welded pipe. It has a forming angle (adjustable) with the centerline of the forming pipe when the pipe is rolled. It is welded while forming. The weld seam is a spiral. The advantage is that it can produce more than the same specification. SSAW Pipe Meaning - Permanent SteelSSAW pipe meaning:It is made by winding a low carbon carbon structural steel or low alloy structural steel strip into a blank according to a certain helix angle (called forming angle), and then welding it together.It can be used in a narrower way. Strip production of large diameter steel pipes. Its specifications are eed in terms of outer diameter and wall thickness.
