Aquatherm North America (NA) has added a new SDR 9 product line to its family of Aquatherm Blue Pipe® options used in mechanical and industrial applications — Aquatherm Blue Pipe SDR 9 MF RP. SDR stands for standard dimension ratio, while 9 is the pipe thickness (or SDR). MF is multi-layer faser (Aquatherm’s proprietary thermal expansion-reducing fiberglass extruded layer). RP stands for raised pressure.

The company says the piping utilizes the latest advances in high-performance polypropylene-random (PP-R) resin technology for improved performance and capabilities in applications such as high-pressure risers, high-temperature heating and district heating, and industrial process systems where a high safety margin is required.

The Aquatherm Blue Pipe MF RP is classified as a polypropylene raised crystallinity temperature (PP-RCT) material in accordance with ASTM F2389 and ISO 15874, as well as a PP-R 125 in accordance with ISO 12162. This ensures that the Blue Pipe SDR 9 MF RP meets and exceeds the most stringent international and national standards for polypropylene pressure piping.
