Introduction of PPR Water Pipe

PPR Water Pipe

PPR pipe is a thermoplastic pipe. Made of polypropylene random copolymer (Random Copolymer Polypropylene) as the base material. It has excellent heat resistance, chemical stability, impact resistance and low density. Therefore, it is widely used in the fields of water supply and drainage, heating, air conditioning and chemical industry.


ppr pipe

The ppr plumbing pipe consists of three parts: outer layer, hollow layer and inner layer. The outer layer is rigid polypropylene to withstand pressure shocks. The hollow layer is foamed polypropylene, which improves the insulation performance of the pipe. The inner layer is smooth non-toxic PPR material. The flatness of the inner wall of the pipe is guaranteed. The accumulation of scale and the adhesion of dirt are reduced, and the service life is prolonged.


The diameter of PPR water pipe generally includes 16mm, 20mm, 25mm, 32mm, 40mm, 50mm, 63mm, 75mm, 90mm, 110mm and other specifications. Different pipe diameters can be selected for installation according to requirements.

Connection method:

The connection methods of PPR Plastic Pipe mainly include hot melt connection and mechanical connection. Hot melt connection is after heating pipes and fittings to a certain temperature. The two are brought into contact with each other by external force, so that they are thermally fused together. After cooling and solidification, a strong connection is formed. The mechanical connection is achieved through threads, snap rings, sockets, etc. More suitable for smaller pipe diameters and lower working pressures.


PPR water pipe has the advantages of corrosion resistance, high temperature resistance, impact resistance, good sealing, no water leakage, easy installation and light weight. It is suitable for water supply and drainage, heating, air conditioning and chemical piping systems in various occasions.


The installation process of PPR hot and cold water pipes needs to pay attention to the following aspects:

(1) The pipeline design should be reasonable and the layout should be reasonable. Avoid obtuse and dead angles;

(2) The bending radius of the pipe must meet the requirements. Avoid pressure loss caused by too small corners;

(3) Pipe joints require precision. When installing, it is necessary to ensure that the joints are firm and there is no water leakage;

(4) The heat insulation layer of the pipeline should be set reasonably to improve efficiency and prevent energy loss.
