Product Description

Prefabricated Directly Buried Insulation Pipe Production Line with PU Spray & HDPE Winding Technology

Recognized as one of the first sets of major technical equipment in Shandong Province, this production line adopts continuous or intermittent spraying processes with high automation and fast production efficiency. It saves raw materials, improves foam closed-cell rate, reduces water absorption, and ensures more reliable product performance with integrated molding technology.

Our company independently develops Polyurethane Spraying Foam Preinsulated Steel Pipe Making Machine, which consists of three parts: Steel Pipe Shot Blasting Machine, polyurethane spray production line, and PE winding production line.

Production line parameter:
(1) Steel pipe range: 206mm-1820mm
(2) Processing capacity:≤250㎡/h
(3) Cleaning class: Sa2.5
(4) Used material: ISO (isocyanate), POLY (premixed polyether polyols), PE
(5) Main equipment: Shot blasting and rust removal production line, Polyurethane spray production line, PE winding production line.

The spraying and winding production process ensures the uniformity of the density of the insulation layer, improves product quality, and reduces production costs.

PUF spray PE winding preinsulated pipe production line consists of the following parts:

1) Steel pipe outwall shot blasting line

2) Polyurethane spray molding line
3) Polyethylene sheet extruding winding line
4) Water cooling line
5) End-cutting equipment

Rust Removal
First, the surface of the steel pipe is derusted, usually by shot blasting or sand blasting, to ensure that the surface is clean and free of rust, oil and other impurities. Preheating: The cleaned steel pipe is preheated so that the subsequent polyurethane foam can better adhere to the steel pipe surface.

Polyurethane spray molding line

The polyurethane raw materials (isocyanate and polyol) are mixed in a high-pressure foaming machine and evenly sprayed onto the surface of the preheated steel pipe. The polyurethane raw materials rapidly foam on the surface of the steel pipe, forming an insulating layer.

Polyethylene sheet extruding winding line

Polyethylene (PE) is wrapped around the polyurethane insulation layer to form an outer sheath. Cooling and shaping: The wrapped pipe is cooled and shaped to ensure that the outer sheath and insulation layer are tightly bonded to form a stable structure.
