New PP-R/AL/PP-R composite pipe extrusion line is developed from PP-R pipe technology, which overcome disadvantages and limits in PPR pipe, such as high expansion parameter, bad creep resistance
and distortion etc. First, use PPR pipe extrusion line produce PPR pipe as inner layer, and wrapped aluminum foil as middle layer, then coat PPR layer again as outer layer.
It can produce normal PP-R pipe as well as PPR-Aluminum composite pipe extrusion line according to customer' requirement.
