Product Description

HDPE Jacket pipe extrusion line for pre-insulated pipe is designed by Qingdao Huashida Machinery Co., LTD. It  absorbs and improves developed HDPE pipe extruding technology.
The production line is an integration design composed by extrusion, vacuum calibrating, cooling, pulling, cutting, stacker. Great performance in automatic operation, extrusion capacity, steady and service life etc. Especially compared with the line use internal pressure method, vacuum calibrating method is much better than it for stiffness, pressure resistance and surface smooth.Vacuum calibrating method pre-insulation pipe outside casing extruded line is the advanced and popular machinery in the world.



Advantages


1.High strength and toughness, smooth surface

2.Uniform wall thickness and excellent pressure resistance

3.Superior resistance to environmental stress cracking and impact at low temperatures

HDPE Jacket Process Flow: 
Vacuum feeding PE granule-->hot air dry material-->extrusion plasticizing-->mold shaping-->Vacuum sizing-->water cooling-->Pulling out-->cutting pipe-->carrier laying-off pipe
