COES PP Drainage

Coesprene® is the insert joint drainage system made of copolymer polypropylene + reinforcing charges which is, in terms of strength, exceptionally strong and resistant to mechanical stress.

The programme consists of the multilayer pipe with single socket and with double socket in diam. of 32 to 160 mm. In the fitting sockets, made of PP, there is a “double lip” gasket with stabilising ring to guarantee an improved hydraulic seal even in backflow conditions.

Copolymer PP is made up of molecular chain of polypropylene and ethylene, the combination of which conveys increased elasticity.

Laboratory tests demonstrate resistance to aging of over 50 years.

Coesprene® pipes and fittings are compliant with UNI EN 1451-1.
