Aquatherm's blue pipe (formerly Climatherm) is a polypropylene pressure piping system that is specially engineered for hydronic, geothermal, and industrial applications. Aquatherm Blue Pipe boasts all the unique advantages of Aquatherm Green Pipe such as the strengthening characteristics of the faser layer, but is engineered with thinner walls for higher flow rates, making it the product of choice for engineers and mechanical contractors.

Aquatherm Blue Pipe is high-heat stabilized, allowing it to be manufactured as SDR 11 instead of SDR 7.4. This reduces the weight of the pipe, improves its flow rate and keeps it competitive with comparable non-potable systems, all while delivering the superior performance that customers expect from Aquatherm products.

You may notice that many of the Aquatherm Blue Pipe systems pages are identical to the Aquatherm Green Pipe systems pages — this is not a mistake. The two systems are assembled identically and share the same material properties and advantages. When referencing tables and data, please make sure to identify the proper system you are using.
