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.

          

Main machine for HDPE Jacket pipe extrusion line     

  Main Extruder Efficient single screw extruder with water-cooling force feeding system, and barrel with grooving in the feeding zone are designed to save power of main motor; Long L/D ratio and mixing head are designed to get perfect jellification and high output.

Die head Die-head is mainly composed of mandril, neck mold, spiral body, cover, die-head body, bolts, and heating rings. The inside surface touching with plastic materials is polished and chrome plated to ensure plastic materials flow smoothly and to ensure no rusting. The uniformity of pipe wall thickness can be adjusted by bolts.

 Vacuum Calibration Tank It adopts bronze or stainless steel calibrators;The calibrating sleeve fixed in die-head is mainly used to cool down the fresh pipe and to calibrate the pipe outer diameter. High-efficiency water-spraying cooling to ensure quality of pipes. 

Hauling machine High qualified rubber block is with longer life, we dont accept blocks made by recycled materials. Hauling speed is synchronized with extruder. 

Chipless Planetary cutter      High qualified alloy steel blade; planetary cutting to get smooth edge without plastic scrap; High precision cutting; PLC control.
