HDPE Polyurethane Foam Jacket Pipe Production Line Equipment
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.
DETAILS
Product Parameters
HDPE Jacket pipe extrusion line for pre-insulated pipe is used for extruding thin wall shell to protect the Polyurethane foaming Prefabricated Directly Buried Insulating Pipe. China manufacturer Huashida company adopts vacuum calibration method. The line runs steady. It is easy to operate by Siemens PLC. High-speed and efficient production can save costs for customers. It is an environmental protection and energy-saving production line.
HDPE Jacket pipe: dia. 48-2000mm
Carrier pipes: steel/stainless steel/plastic/copper
Insulation layer: polyurethane rigid foam Material
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
PU Foaming Pre-insulated Pipe Production process Flow:
The production process of "pipe in pipe" (PU Foaming Pre-insulated Pipe) mainly includes three steps: surface pretreatment of steel pipe, production of HDPE outer protective pipe and production of insulation layer.
The production steps of insulation layer are as follows: firstly, the steel pipe is penetrated into the high-density polyethylene outer protection pipe to form a casing structure, and the supports are evenly arranged in the annular space between the steel pipe and the high-density polyethylene outer protection pipe, and the two ends are sealed by flanges; secondly, the casing is hoisted on the foaming platform, and the polyurethane foaming material is injected into the casing by high-pressure foaming machine; finally, the polyurethane material is foamed After curing, the sealing structure at both ends is removed to complete the production process of the insulation layer.
