This type of pipe has a framework of 5 layers: the internal as well as external layers are made from PP-R, which are firmly bound with PP-based glue to the mid-layer of light weight aluminum, which is weII joined with welding.

Greatly decreased linear expansion coefficient, just 1/4 of that of ordinary PP-R pipelines

Improved resistant to impulse under low temperature, immune to UV-ray

Can work under higher temperature and higher pressure.

KING PLASTIC PPR (polypropylene copolymer) pipes and fittings have the advantages of health, environmental protection, high strength, light weight, corrosion resistance, smooth inner wall, no scale, easy construction, easy maintenance, long service life, etc., and can be widely used in the domestic field of hot and cold water supply systems. PPR pipes and PPR fittings can be connected by socket welding.
