PP-R,PP 3layer foam mut pipe line pipe machine plastic machinery

PP-R stable-state pipe is an extension of the traditional PP-R pipe, with is reinforced by short fiberglass in medium layer of the pipe. To overcome the rigidity disadvantage of the PP-R pipe, KONRUN has innovated a new sandwich structure, the inner and outer layer is normal PPR, short fiberglass is combined in the middle to be the strengthening layer; change formula also produce PP three-layer Foam Mute pipe.The pipe is made by a co-extrusion system composed of four extruders, three of them for pipe, one for marking line. The uniquely designed spiral co-extrusion die could allocate the fiberglass regularly in the reinforced layer and bond the three layers into an integer. Compared with the traditional PP-R pipe, such enhanced pipe characters higher rigidity ,lower expansion and higher pressure, and because of the medium fiberglass layer, the pipe can save more expensive material of PPR,.
Considering the convenience for our customers, we as well provide the granulating extrusion line for making the FRP short fiberglass.
