The Myths and the Facts about Spiral Pipe – from IMEC

The wall thickness tolerances of spiral pipe made from continuously rolled coil are obviously smaller than those of straight seam pipe made from reversely rolled plate Spiral pipe is harder to weld The weldability is determined by the type of steel used.

Northwest Pipe Company Water Transmission Group

Spiral weld pipe is manufactured from steel coils formed helically into cylinders. The cylinders are welded as they are formed, using the double submerged arc weld process. This process achieves 100% penetration welds and forms a flawless seam that becomes an integral part of the pipe. We manufacture pipe in lengths up to 130 feet.

Naylor Catalog Page 1 Naylor Pipe Company

Naylor Spiral Buttweld Pipe features two welds along the spiral seam. This creates a pipe structure in which the weld is as strong or stronger than the parent metal. UNIFORM WALL Because thickness tolerances of steel strip are governed by the standards established by the American Iron and Steel Institute, uniform wall thicknesses are assured.

Welded vs. seamless steel pipe American Piping Products

An advantage of ERW pipe is that no fusion metals are used and the weld seam cannot be seen or felt. That’s opposed to double submerged arc welding (DSAW), which leaves behind an obvious weld bead that must then be eliminated depending on the application. Welded pipe manufacturing techniques have improved over the years.
