No creep, no slow crack growth
Highly Resistant Dewatering Pipe. No Creep. No Slow Crack Growth.
Mine dewatering is an essential part of resource extraction, as it lowers the water table around the mine or quarry.
Mine dewatering is usually undertaken for several reasons:
- Ensure stability of mine walls during and after excavation
- Prevent Flooding In underground mines
Pexgol’s excellent mechanical properties offer mine operators a best in class solutions. Made of a unique formulation of Crossed Linked Polyethylene, it is resistant to creep, Slow Crack Growth (SCG), corrosion, low and high temperatures and impact, flexible and high strain resistance which makes it resistant to failure due to water hammer.
Pexgol pipes can be supplied in long length coils (up to Ø12″) or sticks (up to Ø24″) tare a good solution for dewatering lines. Pipes are offered in several standard pressure rating, and tailor made pipes can also be provided.
- Exceptional creep resistance
- Remarkable corrosion resistance
- Excellent environmental stress cracking resistance (ESCR)
- Sedimentation-free pipes
- Impervious to scratches and stone impingement (SCG)
- Features a continuous self-supporting pipe section with no need to anchor the vertical pipe section to the peer wall
- Needs very few pipe connections; sometimes, no connections necessary
- Able to transport pipe from one location in the mine to be reinserted in another location without fear of damaging the pipe
- Can be lifted and moved to second location
- Can be dragged to second location
- Corrosion resistant – horizontal section of the PEXGOL™ mine dewatering pipe can be placed directly on the ground without special precautions to protect from corrosion
- Resistant to UV radiation – even if exposed to sunlight for the duration of pipe usage
- Operating temperatures from -50ºc to +110ºc
