Aquatherm’s Blue Pipe is a polypropylene-random piping system ideal for radiant applications as well as chilled-water, condensing-water and industrial applications. Sized from 1/2” to 24”, it can handle operating temperatures up to 180° F at 100 psi, is rustproof and scale resistant. The company’s newest addition, Blue Pipe SDR 9, provides several advantages over the line’s other SDRs, including: lower wall thickness and weight per ft.; 15% higher flow capacity; and 20-100% higher pressure capability depending on operational temperature. It utilizes the same multi-layer faser wall structure to reduce thermal expansion/contraction.
