PPR-AL-PPR труб

Aluminum-plastic ppr pipe MINGDA PPR Aluminum Plastic Composite Pipes are consisited of five layers. external layer is made of PP-R, the internal layer PE, and the middle layers aluminum. Under the effect of high temperature and high pressure, diffrrent kinds of thermosol compouds and sticks the layers together. Advanced technique of thermosol binding is adopted to produce this type of tubular prlduets. As a result, the intensity of the joints of layers is by no means decreased but increased to such an extent that the intensity of the joints is even greater than the tubular products themselves. Whats more, this type of aluminum tubular products is convenient to be installed and reliable in terms of its performance.Generally speaking,they integrat the advantagesof both PP-R tubular products and aluminummultiunit tubular products ,and thus constitute good substitute products for traditional galvanized tubes and pure plastic tubes
