The Challenge

Tizapa Mine formerly installed an HDPE line were they used to transport slurry. This pipe suffered several failures on the joints, so did the thermo-fusions and the stub-ends as well.

They determinate that the failures were caused by small water hammers on the line.

Pexgol Solution

Supplied in long lengths coils: Of 100 meters each, reducing possible failures in the joints.
It high resistance to water hammers.
Burst pressure: 3 times higher than nominal pressure.
Safe joints: They don’t deform neither detach caused by a pressure surge.
Quick installation: Coils were uncoiled in 1.5 work hours, without any complex equipment.
