PPR tubes and PERT tubes cannot be thermally fused together, mainly because the molecules of the two materials are different, and the melting temperature is also different.

First of all, the molecular structure of the material of PPR pipe and PERT pipe is completely different, and the hot melting must be safe and reliable. Essentially, the material of the hot melting pipe and pipe fittings is the same, and can be completely fused together.

PPR pipe and PERT pipe are two completely different plastic pipes. The scientific name of PPR pipe is three-type polypropylene pipe, which has excellent impact resistance, heat preservation and environmental protection. Heat-resistant polyethylene pipe, PERT has excellent toughness, heat dissipation and temperature resistance, and is mainly used for floor heating radiant heating pipes.

Secondly, the melting temperature of PPR pipe and PERT pipe is different. The melting temperature of PPR pipe is 260±10°C. Then the molecular structure of PERT pipe belongs to medium density polyethylene, which belongs to partial crystalline thermoplastic. The welding temperature is generally lower than 260°C. , at about 230±10°C, the difference in the welding temperature between the two also determines that the two cannot be welded together.

In the actual construction process, if it is necessary to connect the PPR pipe and the PERT pipe together, it is necessary to use metal pipe fittings for conversion connection, so that the hidden danger of leakage can be fundamentally eliminated.
