Buy quality 3PE Steel Pipe Anti-corrosion Production Line from Comrise, a professional manufacturer in China. This highly efficient production line provides a reliable method of creating long-lasting, durable anti-corrosion coatings that are critical for industries like heating, cooling, petroleum, and chemicals.

What is 3PE Steel Pipe Anti-corrosion Production Line?

The 3PE Steel Pipe Anti-corrosion Production Line is a fully automated system designed to coat steel pipes with a three-layer protection structure: FBE (epoxy powder), adhesive, and polyethylene. These materials are carefully applied to create a robust, long-lasting anti-corrosion layer for steel pipes, which are widely used in oil, gas, heating, and chemical pipelines. This production line offers significant advantages such as high processing capacity, stable performance, and ease of maintenance.

Our company independently researches and develops Spray Coating & Winding Thermal Insulation Pipe Production Line, which consists of three parts:

Shot Blasting Rust Removal Line, Polyurethane Spray Coating Line and PE Winding Line.

It is a full automatic equipment for manufacturing thermal insulation pipes, mainly used to produce insulation pipelines for heating, cooling, petroleum, chemical and other industries.

Equipment

Production Process

Steel Pipe Pretreatment & Rust Removal

The surface of steel pipe is derusted by shot blasting or sandblasting to ensure clean surface without rust, oil and other impurities.

Then the cleaned steel pipe is preheated for better adhesion of polyurethane foam.

Polyurethane Foam Spraying

Polyurethane raw materials (isocyanate and polyol) are mixed by high-pressure foaming machine and evenly sprayed on the preheated steel pipe surface.

The materials foam quickly to form a stable insulation layer.

Outer Protective Layer Winding

Polyethylene (PE) material is wound outside the polyurethane insulation layer as outer protective casing.

Then the pipe is cooled and shaped to make the outer layer and insulation layer closely combined.

Cutting and Trimming

The insulation pipe is cut to the required length according to customer needs.

The pipe ends are trimmed to ensure flat end surface for convenient installation and connection.
