Polyurethane-lined pipes are composite pipes that use steel pipes as the base and high wear-resistant, high-elasticity, high-anti-corrosion polyurethane materials as the linings, and are processed through special processes. This kind of pipeline has excellent wear resistance, corrosion resistance, aging resistance and other properties, and can meet the use requirements under various complex working conditions.

The manufacturing process of polyurethane lined pipes usually includes the following steps:

1. Steel pipe preparation: Select a suitable steel pipe as the base body, and perform pretreatment such as cleaning and rust removal.

2. Polyurethane lining production: The polyurethane material with high wear resistance, high elasticity and high anti-corrosion is made into the lining through a special process.

3. Bonding of steel pipe and lining: Bond the prepared polyurethane lining to the steel pipe to form a composite pipe.

4. Processing and inspection: Process and inspect the composite pipe to ensure that it meets the design requirements and performance.

Polyurethane lined pipes offer the following advantages:

1. High wear resistance: Polyurethane lining has excellent wear resistance and can resist the wear and tear of materials on the pipeline.

2. Corrosion resistance: Polyurethane lining has good corrosion resistance and can resist the erosion of various chemical substances.

3. Aging resistance: The polyurethane lining has good aging resistance and can maintain stable performance during long-term use.

4. Environmental protection: The polyurethane lining material is recyclable and meets environmental protection requirements.
