Automated Polyurethane PU Spraying Foam Pre-Insulated Pipe Production Line with Rust Removal Equipment for Large-Diameter Insulation Pipes

Product Description

Polyurethane PU Spraying Foam Preinsulated Steel Pipe Making Machine with Rust Removal equipment

The polyurethane sprayed polyethylene thermal winding preinsulation pipe production line independently developed by Huashida, consists of three parts: External shot blasting and derusting collector production line, polyurethane spraying production line, and PE winding production line.
It is mainly used in pipeline engineering for oil, natural gas, and district heating. This production line uses an automated process to form a uniform insulation layer on the pipe surface, improving thermal efficiency and service life.It has significant economic and social benefits.

Key Processes:
Steel Pipe Pre-treatment and Rust Removal: The steel pipe surface is treated to remove rust, ensuring a clean surface.
Preheating: The cleaned steel pipes are preheated using medium-frequency heating.
Polyurethane Foam Spraying: Polyurethane raw materials (isocyanate and polyol) are mixed using a high-pressure foaming machine and evenly sprayed onto the preheated steel pipe surface.
External Protection: Polyethylene (PE) material is used for wrapping.
Cooling and Shaping: Water cooling system.
Cutting and Trimming: The insulated pipes are cut to the required length.
Trimming: The ends of the pipes are trimmed to ensure a flat end face, facilitating subsequent installation and connection.
Finished Product Output: Automatic unloading and packaging.

Technical Features:
1. Dust removal meets environmental standards(The three-level dust removal )
2. Suitable for the production of large-diameter insulation pipes
3. Automated operation of production lines
4. Spraying saves materials
5. Efficient extrusion of pipelines
6. Automated precision machining of pipeline interfaces

Advantage:
Awarded the first (set) technical equipment in Shandong Province
Evaluation Report on Standardization of Scientific and Technological Achievements in Qingdao City
Having multiple national patents
