API 5L Spiral Steel Pipe Liquid Gas Transportation Welded Steel Pipe For Sale Spiral steel pipes are made by steel coil, extrusion forming under the normal temperature, then taken the technology of double wire and double-faced submerged-arc welded. Spiral steel pipes are made by steel coil, extrusion forming under the normal temperature, then taken the technology of double wire and double-faced submerged-arc welded. During molding process of spiral welded steel pipe, steel plate has uniform deformation and light residual stress, thus the surface has no scratches. Spiral steel pipe has more flexible thicknesses and diameters, especially in making high-grade thick pipes with small or medium aperture, these techniques has incomparable advantages in satisfying your needs.
