Joint coating is applied, usually a shrink sleeve or mortar diaper. Pipe is backfilled. The inside weld is made later. Large Diameter Spiral Pipe Mill Machine, Spiral Welded A spiral pipe mill is used to roll the low carbon steel/ low alloy steel strip into a tube by a certain forming angle and further weld it into a steel pipe by submerged arc welder. With the assistance of our spiral tube forming machines, large diameter pipes can be produced with a narrow steel strip.

Large diameter welded steel pipe production process

May 28, 2021 · Large diameter welded steel pipe production process. Large diameter welded steel pipe production process mainly adopts cold forming process (JCOE), which is a gradual forming method of steel plate, so that the steel plate is formed into the required bending degree under the standard die of the upper punch and the lower die, so as to achieve the required diameter size. Petrosadid:Longitudinally Welded and Double SAWLongitudinally Welded and Double SAW. Welded 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).

Shear molding:the steel plate production line along the outer edge of the spiral curl into a tube. D. Butt cut:double-sided submerged arc welding using advanced technology to pre-welding, internal welding, outside welding. The welded steel pipe using a plasma-foot cut to specification length.

SSAW Steel Pipe, Spiral Submerged Arc Pipe, SAWL Steel Pipe

The spiral steel pipe feeds the strip steel into the welded pipe unit. After rolling by multiple rollers, the strip steel is gradually rolled up to form a round tube blank with an open gap. The reduction of the squeeze roller is adjusted to control the weld gap at 1~ 3mm, and make both ends of the welding joint flush. Machine of manufacturing SSAW steel pipe. Edge planing machine, edge milling machine, pipe Spiral Steel Pipe Manufacturers and Suppliers - Made in The spiral steel pipe is a spiral seam steel pipe which is made of steel coiled coil as raw material, which is often heated and extruded, and welded by automatic double wire double-sided submerged arc welding process. The spiral steel pipe feeds the strip steel into the welded pipe unit.
