The difference between aluminum plastic composite pipe and PPR aluminum plastic
Plastic pipe hot and cold water and hot water in different PPR differences and connections, plastic pipe is connected with the copper fittings, so linear expansion is not the same, the waste can not be recycled, while the PPR pipe is hot melt connection, linear expansion, the raw material is three PPR type polypropylene, can be recycled, so PPR tube gradually replace the plastic pipe
papAluminum plastic composite pipe is the earliest water supply pipe replacing cast iron pipe, and its basic composition should be five layers, namely, inside and outside are plastic, hot melt adhesive, aluminum alloy, hot melt adhesive, plastic.PPR plastic composite pipe is composed of five layers, the middle layer of thin aluminum layer, the outer layer is PP-R, the inner layer is PE-RT, between the layers of imported hot melt, extruded under high pressure and high temperature, five layers of organic compound, corrosion resistance, light weight, high mechanical strength, good heat resistance, no fouling and long service life long and other excellent characteristics.Steady state tubes are stable states by definition. Because the PPR pipeline is changeable and the hardness is not enough, it can only be used in the Ministry of construction. However, according to China's national conditions, some home improvement pipeline is not buried, so manufacturers in the PPR installed in the aluminum layer to stabilize its status. The aluminum layer of the stationary tube also acts as a barrier to oxygen and a low transmittance. Solve the problem of moss easily in PPR pipeline.
In the home improvement, the gas pipe is now using aluminum plastic pipe, our factory gas aluminum pipe has the following characteristics:1, with metal pipe of considerable intensity, and easy to bend, eliminate the brittleness of metal tube, bending does not rebound;2, flame retardant characteristics, can transport flammable, explosive gas and oil;3, heat insulation performance is good, the thermal conductivity of 0.45W/m = K;4, easy cutting, machining, special pipe connection without tapping buckle, small caliber pipe coil supply, arbitrary long, curved, save elbow, pipe fittings, convenient installation and construction, compared with metal pipe, can save the construction costs of 80%;5, the service life of up to 50 years;6, light weight, only 1/10 of galvanized pipe; save freight, reduce costs;7 、 the aluminum alloy layer has electrical shielding effect and magnetic shielding effect;8. It can be buried directly in the ground and inside the wall. The metal detector is used to detect the seat of the pipe.
