PERT AL PERT multilayer composite pipe

PERT-AL-PERT PIPE

The multilayer pipes PERT/AL/PERT are composite pipes that are produced by the overlapping method .They are composed of an inner and outer layer of PERT, that are bonded by a special glue to the intermediate layer of aluminum. By that way, a perfect oxygen barrier is accomplished, that ensures their perfect connection.
