With the deepening of coal mining, the requirements for underground pipeline materials are getting higher and higher. Due to the poor corrosion resistance and complex connection methods, the traditional steel pipe materials can no longer meet the needs of modern coal mines. At this time, plastic-coated steel pipe, as a new type of pipeline material, has gradually been widely used. Manufacturers of plastic-coated steel pipes inside and outside
Plastic-coated steel pipe is a combination of steel pipe and plastic coating to form a new type of composite pipe material. This material not only has the strength and pressure resistance of steel pipes, but also has the advantages of corrosion resistance, insulation, and non-toxicity of plastics. Therefore, in coal mines, plastic-coated steel pipes have the following advantages:
1.Strong corrosion resistance. The outer layer of the plastic-coated steel pipe is coated with polyethylene, epoxy resin and other anti-corrosion materials, which can effectively resist the erosion of various acid, alkali, salt and other corrosive substances in the underground, and greatly improve the service life of the pipeline.
2.The connection is simple. Plastic-coated steel pipes can be connected by welding, threaded connection, flange connection and other methods, which is simpler and more convenient than traditional steel pipe connection methods.
3.Lightweight. Plastic-coated steel pipes are lighter in weight than traditional steel pipes, making them easy to install and transport.
4.Good insulation. The plastic coating of plastic-coated steel pipe has good insulation properties, which can effectively prevent potential safety hazards caused by electric sparks.
5.Non-toxic and environmentally friendly. The plastic-coated steel pipe is made of environmentally friendly materials, which is non-toxic and tasteless, and harmless to the environment.
In the process of using plastic-coated steel pipes in coal mines, the following points need to be noted:
1.During the installation process, it is necessary to ensure the fixation and support of the pipeline to avoid excessive pressure or bending stress of the pipeline.
2.During transportation and installation, it is necessary to avoid strong impact or friction of the plastic-coated steel pipe to avoid damaging the coating.
3.In the process of use, it is necessary to regularly inspect and maintain the pipeline, find and deal with the existing problems in time, and ensure the normal use of the pipeline.
4.During installation and maintenance, it is necessary to comply with relevant regulations and operating procedures to ensure construction safety and quality.
In short, as a new type of pipeline material, the plastic-coated steel pipe used in underground coal mines has the advantages of excellent corrosion resistance, simple connection, light weight, good insulation, non-toxic and environmental protection, and is an ideal choice for modern coal mines. In the future development, with the continuous progress of technology and the expansion of application fields, plastic-coated steel pipes will be used in more fields, bringing more convenience and safety to human production and life.
