This line has two patent techniques, which can produce PE-AL and PPR-AL composite pipes. PPR-AL composite pipe with PPR in the inside and outside layers, which ensure that pipes and pipe pieces are welded by hot-melting and at the same time no leakage.
Advanced technics, co-extrude the argon ark welding or ultrasonic lap welding), inside and outside pipes and hot-melting glue by adopting co-extrusion and one-step manners. Firm cementing, narrow and glabrous welding line, high production speed, and excellent final products.
Co-extrusion die head, the inside and outside pipes, hot-melting glue and aluminum pipe are felted directly and hard in the high temperature. Aluminum pipe molding and calibration bushing adopt the nano diamond tectorial technics, which make the inside and outside surface of aluminum pipe glabrous and no friction imprints, and all ensure the welding quality and long lifetime, which can reach 10 thousand hours, and at the same time avoid the limitation of changing the calibration bushing regularly and then decrease the productivity because of the short lifetime of calibration bushing. Moreover all these advantages can reduce the production taches, shorten the production line length, and lessen the workshop investment and workers expenses.
Adopting PLC touching screen centralized controlling, it is easy in operation and stable in run.
