Cost Efficient & Lightweight Fully Welded Pipe
Rolaweld is helically formed to produce a consistently cylindrical spiral welded pipe which exhibits exceptional strength with the added bonus of being lightweight and cost effective.
The continuous weld bead acts like a reinforcing rib and gives 10-15 percent additional radial stiffness in comparison to longitudinal welded pipe.
Rolaweld’s construction method and welding characteristics conform to AS4041 (1992) and AS1579 (1993). Our products are widely used throughout Australia and have also been used extensively in international projects.
