Plastic pressure pipe systems

Plastic pressure pipe systems are used for the conveyance of drinking water, waste water, chemicals, heating and cooling fluids, foodstuffs, ultra-pure liquids, slurries, gases, compressed air and vacuum system applications, both for above and below ground applications. Plastic pressure pipe systems have been in use since the 1950s
The most common pipe systems are named after the materials they are made from. The type of pipe in use is dependent on the material passed through the pipe, the operating pressure, and the operating temperature. To ensure pipes from different vendors work together, the ISO set standards for manufacturers to follow.
Polypropylene is suitable for use with foodstuffs, potable and ultra pure waters, as well as within the pharmaceutical and chemical industries.[citation needed] Polypropylene is adversely affected by UV radiation and requires insulation or a protective coating if installed outside.
