Pipe systems for mines
In addition to the external impact on pipes and pipe systems, the mine’s level differences also mean that high pressures are required to pump media from low to high points. Mining environments therefore require durable pipes that can withstand high pressure both inside and outside. Extena develops and manufactures PE pipes for applications that require higher pressure ratings. In environments where large level differences are a critical factor, Extena high pressure pipes can be the solution. These pipes have a greater thickness and a higher ring stiffness than traditional pipes, which means they can withstand high internal pressures as well as high external loads. We offer both homogeneous high pressure pipes and multiple layer high pressure pipes (HexelOne®) for extra resistance to high pressures.
Drill cuttings and slurry
The transportation of e.g. drill cuttings and slurry (tailings and mine water) requires extra strong pipelines that can withstand both high pressures and excessive wear on the inside. Drill cuttings consisting of crushed rock with a grain size of up to 6 mm place great stress on the inside of pipes. Our durable, homogeneous multilayer pipe egeSlurry® with a protective inner layer is perfect for these types of demanding conditions.
In mines, static electricity is also generated when pumping dry and flammable media, for example. For these applications, we have developed egeStatic®, a co-extruded homogeneous pipe made of PE-EL that reduces the risk of static electricity generation.
We can also offer prefabricated pipes with pre-assembled flange joints, which facilitates the jointing and installation of pipe systems in the mine. These pipes are joined on site and are available in dimensions up to 1600 mm.
In addition, we offer several other types of pipes and pipe fittings that meet all the requirements of the mining industry.
• Tough environment with external impact on pipes and pipe systems
• High and low points increase pump pressure significantly
• Abrasive media wears the inside of pipes
• Static electricity
• Flammable media
