PIPES PE100 PRESSURE PIPES
On-site Installation Guide
Anchoring is required, only when fitting with a rubber sealing ring are used or, at the points where valves are installed. Anchoring is not necessary, when heat-welded fittings are used.
HDPE pipes can, at ambient temperature, can be bent to a radius of R=12-20 times above their outside diameter (DIN 16933 specification ).

When a Polyethylene pipeline is sealed under a pressure test there will be a reduction in pressure ( pressure decay ), even in a leak free system, due to the visco elastic ( creep ) response of the material. This pressure decay is non-linear in an unconstrained pipe.
