PP pipes and fittings for internal sewers

PP pipes and fittings have a high resistance to both high temperatures (60°C run up to 95°C for short periods of time) and low temperatures (up to -15°C).

Both the PP pipes and fittings have a high chemical resistance to most aqueous solutions, to the aggressive action of caustic substances or of aqueous acid solutions. Thus, PP pipes and fittings can be used to transport basic or acid aqueous solutions, mineral salts, etc. that have the pH between 2 and 12. Therefore, PP pipes and fittings are resistant to the detergents in the water from the washing or dishwashing machines.

The gaskets used for pipes and fittings are made from elastomeric material that guarantees a long-lasting resistance even in harsh conditions.

Given that water in suspension may contain different types of particles, abrasion resistance needs to be taken into consideration for pipes and fittings. The PP system ensure a high resistance to abrasion even in harsh conditions due to the interior walls that are extremely smooth.

This is an important feature especially for buildings that are subject to vibrations or that are located in areas with high seismic risk. This feature is due mainly to the socket and gasket joining that also works as an expansion compensator.

Shock resistance is optimal at normal temperatures. This resistance is valid even at low temperatures.

The low weight of the components that are part of the PP pipes and fittings systems ensures an extremely high manoeuvrability in terms of transport, storage and components handling as well as its installation. Likewise, the gaskets ensure an easy and tight joining of the components, that allows a fast installation. For a fast installation is recommended to lubricate the gasket and the end of the pipe that will be provided with a socket.
