PE-Coated PU Spray Foam Insulated Pipe Making Machine for Heating /Hot/cooling water
Pipe diameter range: 500-1600MM
Our company independently developed the spray winding insulation pipe production line, which consists of three parts: shot blasting and rust removal production line, polyurethane spraying production line, and PE winding production line.
This unit utilizes either continuous or intermittent spraying processes. This highly automated process offers high production efficiency, conserves raw materials, increases closed-cell foaming, reduces water absorption, and utilizes a three-in-one molding process for more reliable performance. This product is low-carbon, environmentally friendly, and offers significant economic and social benefits.
Production line parameters:
(1) Steel pipe coverage: 206mm-1820mm
(2) Processing capacity: ≤250m2/h
(3) Cleaning level: Sa2.5
(4) Materials used: Black material (isocyanate), white material (combined polyether), polyethylene
(5) Main equipment: Shot blasting and rust removal production line, polyurethane spraying production line, PE winding production line, consisting of three parts
