Ⅰ. Pipe Introduction:
PP-R pipe, also called random copolymerized polypropylene pipe, is a new generation of environment-friendly construction material developed in the 1990s.

Ⅱ. Application:
1). The civil-use and industrial-use construction inner cold/warm water and water-giving systems;
2). Public sites,(such as schools, hospitals),gyms(such as swimming pools, playground);
3). Drinking water systems and food industry management system;
4). Garden and warm room’s irrigating systems;
5). Traditional heat-giving/heat-absorbing systems;
6). Central air-conditioner system;

Ⅲ. Advantage:
1). Sanitization & non-poison: green products can be used to pure clean drinking water system;
2). Super heat-proof: withstand temperature as high as 95°C;
3). Corrosion-proof & non-fouling;
4). Warmth-protecting & energy-saving: the heat-transferring coefficient is only 1/200of the metal pipe;
5). Light weight & high strength: proportion is only 1/8 of metal pipe;
6). Long service life up to 50 years;
7). Easy reliable installation and beautiful appearance.

Ⅴ. Installation Instruction:
The thermo fusion connection of plastic pipe is the welding of two parts of homogeneous materials.
PPR pipe and pipe fittings welding steps
Cut the pipe
Insert pipe and fitting in thermo heating heads simultaneously.
Insert the heated pipe into fitting without rotation, and the angle between the pipe and fitting shall not be greater than 5 degrees.
