2.1 Distribution pipes
Installation methods depend on the pipe material used. Installation is easier in RFU than in RCU, due to less expansion caused by temperature variations.
Conventional installation methods can cause axial stresses on steel tubes due to frictional forces between the liner and the surrounding soil.
To control these friction forces and ensure that they remain at an acceptable level, the tubes should be surrounded by a layer...
