Coestilen® is adrainage system made of polyethylene welding that is exceptionally elastic and resistant to mechanical stress and vibrations. The program consists of pipes and fittings with diam. from 32 to 315 mm and includes a wide range of connection fittings and service connections to sanitary and sewage systems. The high molecular weight PE is a guarantee against cracking due to prolonged use. Moreover, it is particularly suited to absorbing mechanical stress of significant intensity and therefore specific for installations in seismic areas. It also has high resistance to operating temperatures between -40° and + 70°C, with the ability to manage peak loads at 95°C. Coestilen® pipes and fittings are compliant with standard UNI EN 1519.

Coesprene® is a push-fit drainage system made of copolymer polypropylene + reinforcing charges that has exceptional strength and is resistant to mechanical stress. The programme consists of a multilayer pipe with mono and dual sockets and fittings in PP ranging from a diameter of 32 mm up to 160 mm.The pipes and fittings have a "mono-lip" seal to ensure a greater hydraulic seal even during backflow. The PP copolymer is composed of a molecular chain of polypropylene and ethylene, the combination of which gives greater elasticity. Laboratory tests demonstrate resistance to aging of over 50 years. Coesprene® pipes and fittings are compliant with standard UNI EN 1451-1.
