Can PE pipes be connected with PPR?

In the pipeline construction in Wuhan, Hubei and other places, PE pipes and PPR pipes are common pipes. PE pipes are widely used in water supply and drainage, gas transportation and other fields due to their good flexibility and corrosion resistance; PPR pipes are favored in indoor cold and hot water supply systems due to their excellent hygienic properties and hot melt connection convenience. Many people will be curious, can PE pipes be connected with PPR? The answer is no, there are many hidden dangers in directly using PPR pipe fittings to connect PE pipes.

PE pipes and PPR pipes are made of different materials, which is the fundamental reason why the two cannot be directly connected. PE pipes are made of polyethylene resin, while PPR pipes are random copolymer polypropylene materials. Different molecular structures determine the difference in their melting point and performance. The melting point of PE pipe is relatively low, generally around 130 ° C, while the melting point of PPR pipe is about 160-170 ° C. If the PE pipe and PPR pipe are forcibly connected by hot melt, during the heating process, due to the different melting points of the two, it is difficult to achieve uniform melting, which will lead to the failure of the connection part to fully integrate. Even if the temporary connection is successful, in the long-term use process, with the influence of temperature changes, water pressure fluctuations and other factors, the interface is prone to gaps, which will lead to leakage problems.

In addition, the mechanical properties and expansion coefficients of PE pipe and PPR pipe are also different. PE pipe has strong flexibility and impact resistance, while PPR pipe has high hardness and rigidity. When the piping system is subjected to external force or temperature changes, the degree of expansion and contraction deformation of the two pipes is different, which will generate additional stress on the connection part, making the already weak interface easier to loosen and break. Therefore, forcibly connecting PE pipes with PPR pipe fittings will not only fail to ensure the connection effect, but also pose a serious threat to the safe operation of the entire piping system.

In the process of pipeline connection, the correct approach is to use their corresponding connection methods and pipe fittings to connect similar pipes. PE pipes usually use hot melt connection or electrofusion connection. Through special hot melt equipment or electrofusion pipe fittings, the pipe and pipe, pipe and pipe fittings can be integrated at the molecular level to form a firm and sealed connection; PPR pipes are also suitable for hot melt connection. After heating the pipe and pipe fittings to a suitable temperature, they can be quickly connected, and a tight connection can be formed after cooling.
