Corrugated pipes
The corrugated plastic pipes are produced by high density polyethylene (HDPE) and their role is to provide mechanical protection, from stresses and abuses, to the inner aquifer pipe . At the same time, they are offered as a guide for the replacement of the inner (aquifer) pipe, in case of problem, without causing damage and leftovers.
These pipes provide thermal insulation, waterproofing and also soundproofing although it is not required, because the flow in the plastic pipes is noiseless. They are available in three colors (blue, red and black) in coils of 50m.
In case of ultraviolet radiation, black colored corrugated pipes with carbon black must be used for UV protection.
