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

1. Selection of high-quality raw materials

Mining plastic-coated composite steel pipe raw materials are strictly screened and tested to ensure that their quality meets the standards. This step is to ensure the safety performance of the pipe is the basis.

2. Adopt advanced production technology

Mining plastic coated composite steel pipe adopts advanced production processes, such as internal and external coating, fusion winding, etc., to ensure that it has good pressure resistance and wear resistance. These processes not only improve the mechanical strength of the pipe, but also enhance its corrosion resistance.

3. Strict quality control

In the production process, each process is subject to strict quality control to ensure that the product meets the standards. This includes the uniformity of the coating, adhesion, corrosion resistance and other aspects of the test.

4. Through the testing of professional organizations

Mining plastic coated composite steel pipe is tested by professional organizations to ensure that its safety performance meets the standards. These tests include coating thickness, adhesion, corrosion resistance, flame retardant properties.

Second, mining plastic coated composite steel pipe introduction

Plastic coated composite steel pipe for mining is a kind of pipe which is composed of inner and outer plastic layer and intermediate steel layer, which has excellent corrosion resistance, abrasion resistance and pressure resistance. At the same time, due to the internal smoothness of the steel pipe, it is not easy to scale, so it can greatly reduce the resistance of the fluid in the pipe and improve the conveying efficiency.

Third, the flame retardant properties of mining plastic coated composite steel pipe

The flame retardant property of mining plastic coated composite steel pipe mainly depends on its coating material. At present, the common mining plastic coated composite steel pipe coating on the market is mainly epoxy resin coating, polyurethane coating and chlorinated polyethylene coating. These coatings have good flame retardant properties to a certain extent.

1. Epoxy resin coating

Epoxy resin coating has excellent mechanical properties and good chemical corrosion resistance, but also has a certain degree of flame retardant properties. When the fire source comes into contact with the coating, the epoxy resin will quickly foam to form a protective layer to prevent the fire from spreading, thus achieving the purpose of flame retardancy.

2. Polyurethane coating

Polyurethane coating also has good flame retardant properties, which can effectively prevent the spread of fire in case of fire and other emergencies, and reduce the hazards of fire on the surrounding environment and equipment.

3. chlorinated polyethylene coating

Chlorinated polyethylene coating also has good fire-retardant properties, can be maintained at high temperatures to maintain stability, effectively prevent the spread of fire.

Fourth, the connection of mining plastic-coated composite steel pipe

Mining plastic-coated composite steel pipe connection methods are diverse, including screw connection, groove connection, flange connection, welded, bimetallic connection, socket, pipe joints, sealing connection, etc. These connections are not only easy to operate, but also can be used to prevent the spread of fire. These connections are not only easy to operate, but also ensure the firmness and sealing of the connection.

1. Silk screw connection

Suitable for small pipe diameter (DN15-DN100), easy to operate, quick installation.

2. groove connection

Suitable for multiple pipe diameters (DN65-DN400), quick installation, without damaging the coating of the steel pipe.

3. Flange connection

Applicable to any caliber, reliable connection, good sealing, but the cost is higher.

4. Welding

Suitable for occasions requiring high-strength connections, but requires specialized welding equipment and skills.

5. Bimetallic connection

Suitable for pipe connection of different materials, with firm connection and good sealing.

6. socket, pipe section, sealed connection

Suitable for occasions requiring frequent disassembly and maintenance, convenient connection, simple maintenance.

Fifth, the use of mining plastic coated composite steel pipe precautions

1. Procurement precautions

When purchasing, you should choose products from regular manufacturers with production licenses and product quality inspection reports. This ensures reliable product quality and avoids the use of inferior materials.

2. Construction precautions

At the construction site, the operation should be carried out in strict accordance with the design requirements and construction specifications. Ensure that the coating thickness meets the standard requirements to avoid inadequate coating thickness due to improper construction, which will affect the anti-corrosion performance of the pipeline.

3. Maintenance precautions

In daily use, the mining plastic coated composite steel pipe should be inspected and maintained regularly. Timely detection and treatment of problems, such as coating damage or pipe leakage, can extend the service life of the pipe and ensure the normal operation of the system.
