Spiral rib pipe combines the strength of metal with the hydraulic characteristics of today’s most efficient pipes. Available in diameters up to 120" (steel) and 72" (aluminum). The core material for aluminum alloy pipe is specially formulated to resist the effects of corrosion and abrasion.

Spiral pipe is formed from a coil of prime metal into rigid steel tubing with a 4-ply spiral lockseam. Smooth interior pipe for low friction loss with the grooved seam entirely on the outside. Crushing resistance approximately 2 ½ times that of longitudinal lockseam or welded pipe.

Spiralweld pipe is more flexible and customizable, allowing for larger diameters and longer lengths with varying levels. Another benefit of spiralweld pipe is that it is efficient and cost-effective, creating greater possibilities for less. Upon receipt of the coil, it is placed on a horizontal uncoiler mandrel and fed into the straightener.
