Water supply pipes

PP-R, PP-RCT and multilayer pressure pipes for hot, cold and drinking water, including UV-resistant lines for exposed runs. The brands are Polymelt (POLO-POLYMUTAN, POLO-ECOSAN, POLO-UV, POLO-POLYMUTAN ML5, Polymutan and Polymelt UV), Georg Fischer Aquasystem, Aquapa, Bänninger, Polo Egypt and KAS.

PP-R (polypropylene random copolymer) pipe carries hot and cold water, including drinking water, inside buildings. Pipes and fittings are joined by heat fusion welding into one leak-free piece, and the material does not corrode.

PP-RCT is a polypropylene with a modified crystal structure that keeps more of its strength at high temperatures than standard PP-R. It suits hot water and higher pressures, and can allow thinner walls for the same rating. AtlasPlast supplies both, from Polymelt and Bänninger.

For exposed runs on roofs, outdoors and in irrigation, use a UV-resistant system: POLO-UV ML5 fibre pipes with PP-R fittings, or Polymelt UV, which has a black UV-resistant outer layer and is rated 25 bar at 20 °C and 11 bar at 70 °C.

Most PP-R lines run from Ø 20 to 110 mm, and Georg Fischer Aquasystem goes up to Ø 200 mm. Pipes come in 4 m lengths (some brands 4 to 6 m) and in pressure classes PN 10, PN 16, PN 20 and PN 25.

The PP-R and PP-RCT lines are made to DIN 8077 and DIN 8078 and to EN ISO 15874. Polymelt Polymutan and Polymelt UV also meet EN ISO 21003 for multilayer pipes.

POLO-POLYMUTAN ML5 from Polymelt is a five-layer pipe that combines PP-R 80, an HPCE compound and PP-RCT for added strength in hot and cold water installations.

The PP-R and PP-RCT water supply range is made for hot, cold and drinking water. POLO-ECOSAN from Polymelt is a PP-R system designed for healthy, corrosion-free drinking water, and Pimtaş compression fittings serve drinking-water networks.

Aquasystem is Georg Fischer’s PP-R pipe system for hot and cold water in buildings, from Ø 20 to 200 mm in 4 m lengths, in PN 10 to PN 25, made to EN ISO 15874, DIN 8077 and DIN 8078.

AtlasPlast supplies KAS PPR pipes and fittings for hot and cold water. It does not supply the KAS PPR-C line. AtlasPlast also supplies KAS faucets.

PP-R pipes and fittings are joined by heat fusion: a welding machine heats the pipe end and the fitting socket, which are then pushed together and fuse into one piece. AtlasPlast supplies Candan welding machines for Ø 20 to 110 mm and runs training courses on correct installation.
