First, the performance characteristics of mining plastic coated composite steel pipe

Mining plastic-coated composite steel pipe is a high-performance piping materials, through the heating and melting technology will be the inner and outer plastic coating and the middle layer of steel pipe tightly combined. This kind of pipe has the following significant performance characteristics:

1. corrosion resistance

The plastic coating of mining plastic coated composite steel pipe has excellent corrosion resistance, which can effectively resist the erosion of acids, alkalis, salts and other chemicals, and extend the service life of the pipe.

2. Abrasion resistance

The inner and outer layers are steel pipes with high hardness and strong abrasion resistance, which reduces the wear and tear in the conveying process and ensures the long-term stable operation of the pipeline.

3. Impact resistance

Filled with polyethylene rigid foam, it can effectively absorb the impact, prevent the pipe from rupturing and improve the impact resistance of the pipe.

4. Flame retardant

The inner coating is made of flame-retardant materials such as polypropylene or PVC, which has high flame-retardant performance and is suitable for environments with high fire resistance requirements such as mines.

5. Ageing resistance

The inner and outer plastic materials have good anti-aging properties, which can extend the service life of the pipeline and reduce maintenance costs.

Second, the application of mining plastic coated composite steel pipe in the wet environment

The corrosion resistance and anti-aging properties of mining plastic coated composite steel pipe make it suitable for wet environments. However, the humid environment may lead to water accumulation inside the pipe, affecting normal use. Therefore, the following points should be noted when using it:

1. Selection of suitable material

In humid environments, materials with high corrosion resistance and aging resistance should be selected to ensure the service life of the pipe.

2. Enhance maintenance

Regular inspection and maintenance of pipelines, timely removal of internal water and dirt, to keep the pipeline clean and unobstructed, to reduce the risk of corrosion.

3. Avoid prolonged immersion

Although the mining plastic-coated composite steel pipe has a certain degree of water resistance, but a long time immersed in a humid environment may still lead to internal damage. Avoid prolonged immersion to ensure the long-term stable operation of the pipeline.
