Characteristics of the equipment
A. Main characteristics of the production line:
(1)UPVC Double walls wave shaped pipe extruding production line has applied high speed double screws extruder.
(2)It has applied PE high efficient screw with channelled cylinder,materials of the inner layer & outer layer are independentlysupplied by two extruders, the inner layer & outer layer can usedifferent colors or materials, high efficient extruding can beguaranteed.

(3)Strong cooled wave shaping system can guarantee continuous highspeed production. Advanced programmable lubrication system makesabrasion of the shaping mould reduce to the minimum. It has long lifetime. It guarantees operation precision and stable quality of pipematerial.
(4)Advanced on-line opening enlarging function of the wave shapingmachine enlarges the opening. It can obviously reduce investment andincrease the production efficiency.

(5)Wave shaping mould made of special alloy material has rather highhardness and abrasion resistance. It has good heat disperse effect.
(6)Advanced mould rapid change system can greatly reduce time of changing mould.
(7)Special type of shaping mould can be designed according to user's requirements.

B. Applications:
Compared with non-profiled pipe of other structure, double wallswave shaped pipe of HDPE can guarantee lightest weight. This means costof the pipe material can be greatly reduced and competitiveness of pipemarket can be greatly improved. Because of the advantages of convenientconnection and reliability and there is no need for special complicatedpipe, double walls wave shaped pipes are widely used in foreigncountries. It can largely replace previous concrete pipe and cast ironpipe. In China, with construction and development of underground sewersystem, double walls wave shaped pipes have huge space for development.
