ASME B31.3 - Longitudinal Seam weld - Pipelines, Piping

Would like to clarify if there are any provision within ASME B31.3 that allows welded pipe to have two longitudinal seam? We have ordered pipe base on ASTM A358 EFW TYP304 CLASS 1,30" NPS 1" thick. The manufacturer (from India) produces the pipe with 2 plates, resulting in 2 longitudinal seam. Hardness Testing of Welded Steel Pipe - FREE UK Press Nov 16, 2020 · Straight seam electric welded pipe (YB242-63) is a steel pipe whose weld seam is parallel to the longitudinal direction of the steel pipe. Usually divided into metric electric welded pipe, electric welded thin-walled pipe, transformer cooling oil pipe and so on. 4. Spiral seam submerged arc welded pipe (SY5036-83) for pressure-bearing fluid

LSAW Steel Pipes Manufacturers, Factory Suppliers,Buy API

Metline is a specialized manufacturer and factory supplier of Longitudinal Submerged-Arc Welded (LSAW) carbon steel pipes for the Oil and Gas, Petrochemical, Agricultural and Construction Industries.

If you have any Longitudinal Seam Welder Manufacturer In China - HUAFEI The longitudinal seam welder is a kind of high-quality, high-efficiency, non-deformation complete universal welding equipment for welding longitudinal seam of 0.5mm-6mm thin-walled cylinder body and conical cylinder. Longitudinal Seam Welders - SEMAC - Quality has futureLongitudinal seam welding of pipes with large diameters is a job that frequently occurs in tank and boiler construction. A vertical welding position is ideal in such cases since, during and after welding, the boiler section already has the right orientation for subsequent work.

Petrosadid:Electric Resistance/ Fusion Welded (ERW and

ERW steel pipe is manufactured through low or high frequency resistances Electric Resistance. Welding seam is in longitudinal. During the ERW pipe welding processes, the electric current will make the heat when flow through the contact surface of the welding area. It will heat the 2 edges of the steel to a point that the edges can form a bond. Petrosadid:Longitudinally Welded and Double SAWWelded pipe (pipe manufactured with a weld) is a tubular product made out of flat plates, known as skelp, that are formed, bent and prepared for welding. The most popular process for large diameter pipe uses a longitudinal seam weld or Longitudinally Submerged Arc Welded Steel pipes (LSAW). Pipe Manufacturing Process / Methods for Seamless & SAW- Submerged Arc Welding (Long seam & Spiral Seam) ERW Steel Pipe Manufacturing Process In the ERW / EFW / HFW pipe process, the first plate is formed in a cylindrical shape and the longitudinal edges of the cylinder formed are welded by flash-welding, low-frequency resistance-welding, high-frequency induction welding, or high-frequency

AP-Tela Oy pipe plant manufactures thick-walled pipes, cylinders and cones by bending a plate and welding the longitudinal seam. Diameter, wall thickness and length can be custom-made. This enables cost-effective optimizing of the pieces. The materials used:Constructional steel, as S235 and S355; Hardened boron steel, as B13S Seam Joint Efficiency Factors for Factory Pipeline Bendsto apply to pipe containing longitudinal seams. This concern extends to wrought factory-made bends that contain one or two seams, manufactured in various eras. C. ONCLUSIONS. Factory-made bends manufactured from plate where the edges are joined at one or two welded seams, from 1940 and later, should be considered to be of equivalent strength

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. Types of Welds & Joints - Weld GuruSep 23, 2020 · Seam Weld. A weld made by arc seam or resistance seam welding where the welding process is not specified. This term infers resistance seam welding. Refer to figure 6-29 below for an example of a seam weld. Spot Weld. A spot weld is a weld made by arc spot or resistance spot welding where the welding process is not specified.

Which Industries are Straight Seam Steel Pipes Widely Used

Sep 22, 2020 · Submerged arc longitudinal seam welded pipe is produced by using a single steel plate as raw material, through JCO or UOE forming, submerged arc welding or submerged arc welding combined with other welding processes. Common ones are X70, X80, X120, etc. The diameter of LSAW pipe is 400-1422mm and the wall thickness is 8-44.5mm.
