With the development of people life, more people cline to use plastic aluminium muutilayer pipe for gas
Gas aluminum plastic pipe is a new type of pipe, which is composed of middle layer welded aluminum pipe, inner and outer layer polyethylene plastic, and hot melt adhesive between layers. Polyethylene is a nontoxic, odorless plastic with good impact resistance, corrosion resistance and weather resistance. Longitudinal welding of aluminum alloy in the middle layer makes the pipe processing the metal compressive strength, and the impact resistance makes the pipe easy to bend and not rebound. Gas aluminum plastic pipe has two major characteristics of metal pipe solid pressure resistance and plastic pipe acid and alkali corrosion resistance. It is a model of the new generation of pipes. The service life of gas aluminum plastic pipe is generally required to be long-term durability according to standards, and the temperature resistance and pressure resistance shall fully meet the requirements of national compulsory standards, under the conditions of working temperature of 60 ℃ and working pressure of 0.4MPa.
◎It has the similar degree as the metal pipe material， and is easy to bend, which eliminates the brittleness of the metal pipe and does not rebound after bending.
◎It has excellent corrosion resistance, high temperature resistance, high pressure, which can be used to transport cold, hot water and other fluids.
◎It has smooth inner wall, and the resistance loss is small when conveying water and other fluids, as well as the scale does not have dirty things.
◎It has low heat conductivity coefficient and excellent heat preservation and insulation，so as to save the thermal insulation materials outside the pipe，and ensure the liquid free of pollution，poison and harm.
◎It's easy to cut and can be connected through pipe fitting，and the small-diameter pipe material can be supplied in rolls and can be cut at any length and bent at will，so as to save the installation cost of pipe fitting
