PEX pipe and tubing freeze-break resistance and benefits addressed in new technical report
The Plastics Pipe Institute (PPI) published a new technical report related to the break resistance of PEX pipe and tubing when fluid inside becomes frozen. PPI is the major trade association representing the plastic pipe industry.
"PPI TR-52 Resistance of PEX Pipe and Tubing to Breakage When Frozen (Freeze-Break Resistance)" explains how proper installation and protection of piping can prevent freezing of fluids inside PEX, how the inherent material properties of PEX can delay freezing of water, and how PEX can resist breaking if the fluid inside does freeze.
