Natural Bend Radius

Natural Bend Radius in Pexgol Pipes:

To create turns with Pexgol pipes laid inside trenches, above the ground or over pipe bridges, the pipe can be bent according to the natural bending table.
The values in table below are relevant for installations at all •ambient temperatures from low subzero temperatures and up to 40°c
For pipe diameters lower than 110 mm use the values of the 110 mm pipes at all pressure classes.
Field bending involves excavating the trench to the appropriate bend radius, then sweeping or pulling the pipe string into the required bend and placing it in the trench.
This kind of pipeline design, which takes advantage of the natural flexibility of the pipe, reduces the number of connections and lowers head losses.

Observe appropriate safety precautions during field bending. Considerable force might be required to field bend the pipe, and the pipe could spring back forcibly if the restraints slip or are inadvertently released while bending.
