Integral pH1


Integral pH1

The INTEGRAL® pH1 range offers the advantages of an INTEGRAL® pipe with high mechanical strength and a passive anti-corrosion coating, the range is suitable for highly aggressive effluents (with <pH4 & >p). The high thickness (1.5 mm for DN 80 and 2.5 mm for DN 2000) of polyurethane applied to the inside of the pipe enables the INTEGRAL® pH1 system to transport virtually all liquids encountered in industry. The seal of the polyurethane film is checked using a Holiday detector test. A complete range of fittings suitable for these networks, permitted on all outes; in order to offer a complete system, Saint-Gobain PAM UK offers shut-off valves, gate valves and slide gate valves, as well as “waste water” air valves.
