Pressure Pipe Systems
National Plastic produces a wide range of UPVC Pressure Pipes to most of the major international standards and dimensions of Metric and Imperial. The pipes are made from 100% virgin UPVC resin and have a minimum required strength MRS=25 mpa so that the pipes meet or exceed the rigorous hydrostatic requirements of the standards. The pipes are produced in a range of colours such as grey, white, blue, purple and carry full printing and identification at 1m intervals according to the standard requirements.
Pipes can be supplied with integral solvent weld joints along with Weldon 717 cement or rubber ring joints using high performance EPDM seals to EN681. The joints exceed the pressure rating of the pipe and can therefore cover all the applications where the pipes are installed.
All pipes produced fall under an ISO 9001:2008 Quality Assurance system and several ranges carry third party verification such as the BSI Kitemark or WRAS certification so customers are assured the pipes are of the highest quality. For export requirements pipes can be supplied in 5.8m (19ft) lengths so they can be loaded into containers without damaging sockets. National Plastic pressure pipes have been operating in demanding conditions for almost 40 years now (See the Worldwide Projects List) and is proof of their outstanding quality and serviceablility.
