The nominal outer diameter dn of PPR water pipe fittings refers to the nominal outer diameter of the PPR water pipe connected to the water pipe. There is a requirement for the key wall thickness of PPR water pipes, which requires that it should not be less than the wall thickness of the same PPR water pipe series S pipe. In other words, the wall thickness of the pipe fitting must be greater than or equal to the wall thickness of the pipe.

High-density polyethylene (HDPE) is a plastic, known for its high-strength density ratio, flexibility and chemical stability, and is an ideal choice for pressure and non-pressure pipeline applications. HDPE pipe is usually made of PE100 resin, and its density ranges from 930 to 970 kg/m 3, which is about 7 times that of steel.
