New stable PP-R pipe extrusion line, is differ with ordinary PP-R
pipe which has expansion co efficiency ( only 1/3 of traditional
PP-R pipe), exposed distortion, UV resistance, low temperature
impact resistance and bad wriggle-resistance. It is composed by
three layers, i.e. inner PP-R pipe, Al foil and covered outer PP-R.
. Adhesive is existing in between layers. The line composed of following units: inner pipe forming, Al foil
wrapping, glue coating, outer layer covering. This line can also
produce normal PP-R pipe.
