What is the difference between the PPR aluminium plastic composite pipe and the steady pipe?,
Aluminum plastic composite pipe has good insulation properties, both inside and outside the wall is not easy to corrosion, because the inner wall smooth, fluid resistance is small; and because can be bent, so to facilitate the installation of construction. As the water supply pipe, aluminum-plastic composite pipe has sufficient strength, but if too much lateral force, will affect the strength, so appropriate for tube or buried in the wall construction, but should not be buried underground. (aluminum-plastic composite pipe can also be buried in the ground, such as a pipe for one, aluminum-plastic composite pipe) aluminum-plastic composite pipe connection is card sleeve (also card type), so the construction is going through a stringent test pressure, test connection is solid. The two is to prevent the regular vibration, the card sets loose. The three is the length of the installation should be sufficient, so as not to pull off.
As the name suggests is a steady pipe steady state. Because the PPR pipe for variable hardness is not enough so the provisions of the Ministry of construction in the can only be used for buried laying. But according to the situation of Chinese buried pipeline is not part of the home improvement so manufacturers in the PPR installation of aluminum layer to the stable state. The other steady aluminum layer can also play a role in blocking oxygen and reduce the transmission rate. To solve the PPR problem. The pipe is easy to be lichened
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 and plasticPPR 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.
