Roll-a-Pipe is exhibiting large-diameter, cross-linked polyethylene pipes known as PEXGOL™ that are highly damage tolerant and abuse resistant and can handle dragging, scoring, crushing, repeated squeeze-off and high temperatures up to 120oC. “PEXGOL™ pipes are perfect for demanding mining applications such as slurry pipes, pipes for tailings transport, paste backfill and for high-temperature brines and ore processing solutions,” the company says. PEXGOL pipes have been used by Dead Sea Works in Israel in desert conditions to carry hot potassium salt slurries for 20 years without pipe replacement while steel pipes had to replaced every year. PEXGOL pipes can also be used at service temperatures double those of conventional polyethylene pipes as shown in the picture.
The far superior wear resistance of PEXGOL pipe compared to conventional polyethylene should significantly increase the time between pipe replacements and/or rotations resulting in large savings in the way of reduced maintenance costs and time.
The pipes can handle severe duty applications such as boiling process solutions used in nickel and copper ore processing. They are also mechanical very tough and are intended for extreme transport applications such as hot brine and hot slurries.
The very smooth and self-lubricating surface of PEXGOL pipes also gives them superior anti-scaling properties and offer significant cost savings through lower friction losses and increased pumping efficiency in slurry transport.
Roll-a-Pipe based in Melbourne is the exclusive Australian distributor of PEXGOL pipes, which are made by Golan Plastic Products in Israel.
