INSTRUCTIONS FOR UNDERGROUND INSTALLATIONS
For all Pexgol pipe classes, the minimum recommended depth of the trench is 60 cm, to prevent mechanical damage to the pipe. If the pipe is to be covered only to prevent solar heating, the designer may reduce this depth.
In cold areas the installation depth may be increased by the designer to prevent freezing of the transported fluids.
For the maximum allowed installation depth for each pipe class, please contact the application engineer.
If required, the width can be increased to allow more comfortable work in the trench. The minimum recommendation depth of the trench is 60 cm, to prevent mechanical damage of the pipe.
For a route change, for example a 90° angle, it is recommended to dig the trench with a suitable radius.
The following table shows the minimum required trench width for Pexgol pipes:
