PU Foam Pre-Insulated Pipe Production Line with HDPE Jacket for 110–2200mm Pipes Featuring Single-Screw Extruder and Vacuum Calibration System
This production line is specially designed for manufacturing PU foam pre-insulated pipes widely used in district cooling, district heating, oil & gas, and large-scale infrastructure projects across the Middle East.HDPE jacket pipe is out case of thermal insulating pipe, which is widely used in central heating, oil, nature gas and other industrial area.
HDPE jacket pipes are produced by vacuum calibration method, with smooth inner and outer walls, a long service life, good anti-corrosion and heat preservation performance, and excellent mechanical properties.
