Pipe systems for high pressure

In mountain environments, mines and structures with large level differences, pipes are required to withstand high pressures. For this type of environment, we offer pipes that can withstand high internal pressures and which also have a high ring stiffness to withstand high external loads.

The traditional method of handling high pressures in pipe systems is to increase the thickness of a standard pipe. However, Extena and egeplast can offer the unique and innovative multilayer pipe HexelOne^®.

HexelOne^® consists of a main pipe made of PE100 RC, two reinforcement layers of PE100 and a protective sheath of 100% high strength PEplus. The result is a pipe system with a normal wall thickness that can withstand up to twice the pressure of traditional pipes (30 bar for water and sewage and 16 bar for gas). HexelOne^® is therefore easier to handle and the high strength sheath also protects the pipe from external impact.

Extena offers two high pressure pipe systems:

Homogeneous standard pipes with increased thickness for high pressures
Standard pipes for high pressures are available in dimensions 16–630 mm for 20, 25 or 30 bar.
