Product Description
The vacuum calibration polyurethane insulation pipe is a highly
efficient pre - insulated pipe. It is constructed with a working
steel pipe at the innermost layer, which is responsible for
transporting media like hot water and steam. The middle PU
insulation layer offers excellent heat preservation, effectively
minimizing heat loss. The outermost plastic outer protective tube,
typically made of high - density PE, safeguards the insulation
layer from external environmental damage and gives the pipe a sleek
appearance.

Production Line Parameters
- Steel Pipe Range: 60mm - 2000mm
- Materials Used: ISO (isocyanate), POLY (premixed polyether polyols), PE
- Main Equipment: Extruding machine, extrusion die model, vacuum calibration tank,
Haul off machine, cooling equipment, cutting equipment,
polyurethane foaming system, pipe assembly platform, etc.
