We are in the midst of prominent PPR Plastic Pipes Exporters, based in
Application and Features
Besides the general advantages of the normal plastic pipes like light weight, pressure resistance, long-life span, against rust and scale, PP-R pipes have following features.
Hygiene and Environment
PP-R is made of high molecular hydrocarbon. It doesn't dissolve in water and is stable for high temperature applications. Due to its high extraction resistance, it doesn't change the organoleptic properties of water and soil. During manufacturing, no harmful substances emerge.
Insulation and Heat Resistance
At high temperature of 70°c for a long time or at the instantaneous temperature up to 80°c , " Heropoly" PP-R hot water supply pipes can fully satisfy the requirements of hot water transporting in buildings. The thermal conductivity of PP-R is 0.23-0.24w/m. '°C, which is the lowest among various plastic pipes. Generally, no thermal insulation measures need to be taken. Therefore, PP-R is a kind of very good energy-saving pipe for your choice.
Easy Installation
In the "Heropoly" PP-R pipe system pipes and fittings are manufactured from same type of material and result in homogeneous joints. With respect to installation techniques, such as: solvent cement connecting, the socket welding made by heating the sockets and pipe ends by electrical heating elements is more reliable.
