Thermoplastic pipe;Aluminum-plastic pipe that is better

Thermoplastic pipe is a little better, but the heating pipe is recommended to use aluminum-plastic pipe.

PPR pipe used as hot water pipe is not good, the highest temperature is only 90 degrees, long time will be aging, cold water pipe is no problem. Aluminum-plastic pipe temperature 110 degrees, but the pressure is not as high as PPR only 10 kilograms, PPR has 16-20 kilograms of pressure.

Aluminum-plastic pipe is connected with all-copper fittings, so the linear expansion is not consistent, the scrap can not be recycled, while the PPR pipe is a hot-melt connection, the linear expansion of the same, the raw material of the PPR is a three-type polybutylene, can be recycled.

1, with the strength of the metal pipe, and easy to bend, eliminating the brittleness of the metal pipe, bending does not rebound;

2, with flame retardant properties, can be transported to flammable, explosive gases and oils;

3, thermal insulation and heat preservation performance is good, and its coefficient of thermal conductivity of 0.45W/m-K;

4, easy to cut, processing, can be used for special pipe fittings Connection without tapping buckle, small diameter pipe supply in rolls, any length, any bending, saving elbow, pipe fittings, installation and construction is convenient, compared with the metal pipe, can save 80% of the construction costs;

5, service life of up to 50 years;

6, lightweight, only one-tenth of the galvanized pipe; to save freight costs, reduce costs;

7, the aluminum alloy layer has a Electric shielding effect and magnetic shielding effect;
