GWE - Model RC -Water Distribution Control
When planning and implementing piping construction projects, the economy of the laying method used is becoming increasingly important. Manufacturing a complex sand bed, disposing of the excavated earth and compacting the pipeline zone can bind significant human and financial resources. The latest PE100RC materials do not require a sand bed. If installed without a sand bed, point and linear tensions (e.g. due to stones or fragments) can affect the pipe. Combined with the operating loads, this can cause tension cracks in pipes made of conventional materials.
The tension cracks would form inside the pipe walls, gradually spreading outwards (crack propagation) and cause the pipeline to collapse. This tension crack formation due to point loads can be avoided by using pipes made from state-of-the-art material PE100RC, which have lateral concatenations in the amorphous components at a molecular level. Cracks cannot propagate outwards through the pipe walls, or do not form in the first place.
GWE RC-Control pipes are built using co-extrusion processes. They are 100% PE100RC, and have an indicator layer color-coded for the respective use: drinking water = black, blue outer layer
GWE RC-Control pipes are designed specifically for sand bed-free laying. They are suitable for laying in plowing and/or milling processes as well as relining measures. They can be connected homogeneously using butt welding methods or with electro-welding joints, and have a service life of > 100 years.
GWE RC-Control pipes bear the DIN Certco and DVGW quality marks and are externally monitored by accredited test laboratories
