Asahitec™ PP-RCT Pipe

Asahitec Logo Green

PP-RCT is the latest advancement in polypropylene polymers and has a wide range of benefits for commercial plumbing and HVAC systems. It has a more complex crystalline structure that provides greater pressure capabilities at higher temperatures than conventional PP materials.

Both Climatec™ and Watertec™ pipes are manufactured with patented Fibercore™ technology. Fibercore™ PP-RCT pipes consist of three co-extruded layers that make one homogenous pipe. The middle layer consists of mixed short fiberglass strands and PP-RCT, which is isolated by solid layers of PP-RCT on the inside and outside of the pipe. The middle Fibercore™ layer reduces expansion and contraction by up to 75 percent which reduces the installation cost by minimizing expansion loops and quantity of supports required in above ground systems. While the fittings do not have Fibercore™, fittings weld directly to all of Asahi’s PP-RCT systems.
