Diameter 219 internal and external epoxy plastic-coated steel pipe is a new type of pipeline material, which has excellent performance and wide application prospects. The following will be introduced in detail from its materials, manufacturing processes, performance characteristics and application fields. Plastic-coated composite pipes inside and outside
1. Materials. The main materials of epoxy plastic-coated steel pipes with a diameter of 219 are steel pipes and epoxy resins. Steel pipes are made of high-quality steel through hot rolling or cold drawing process, which has the advantages of high strength and good corrosion resistance. Epoxy resin is a high-performance resin material with excellent corrosion resistance, wear resistance and weather resistance, and can be tightly combined with steel pipes to form a high-performance composite material.
Second, the manufacturing process.
The manufacturing process of 219 diameter internal and external epoxy plastic-coated steel pipes mainly includes the following steps:
1.Steel pipe pretreatment: The steel pipe is pretreated with surface rust removal and cleaning to ensure the cleanliness and roughness of the steel pipe surface.
2.Epoxy resin coating: The pretreated steel pipe is put into the epoxy resin, and the epoxy resin is evenly coated on the surface of the steel pipe by impregnation or spraying.
3.Curing: The painted steel pipe is heated and cured to make the epoxy resin tightly combined with the steel pipe to form a high-performance composite material.
4.Testing: Carry out quality inspection on the cured steel pipe, including the inspection of appearance, size, strength, etc., to ensure that the product quality meets the standards.
3. Performance characteristics.
Diameter 219 internal and external epoxy plastic-coated steel pipe has the following performance characteristics:
1.High corrosion resistance: Epoxy resin is able to extend the service life of pipes due to its excellent corrosion resistance and ability to resist various chemicals.
2.Good abrasion resistance: Epoxy resin has high hardness and can resist abrasion and scratches, so it is suitable for various harsh working environments.
3.Good weather resistance: Epoxy resin has excellent weather resistance and can resist the erosion of natural factors such as ultraviolet rays, rain and snow, so it is suitable for use in various climatic conditions.
4.Environmentally friendly and non-toxic: the inner and outer epoxy plastic-coated steel pipes with a diameter of 219 will not produce harmful substances during production and use, and meet the requirements of environmental protection.
5.Easy installation: The inner and outer epoxy plastic-coated steel pipes with a diameter of 219 are connected in a variety of ways, and the appropriate connection methods can be selected according to different working environments and needs, and the installation is convenient and fast.
Fourth, the field of application.
Diameter 219 internal and external epoxy plastic-coated steel pipes are widely used in the following fields:
1.Petrochemical industry: used to transport oil, natural gas and other chemical substances, with the advantages of corrosion resistance, wear resistance, weather resistance and so on.
2.Municipal engineering: used in urban water supply, drainage and other pipeline systems, with the advantages of environmental protection, non-toxic, easy installation and so on.
3.Electric power industry: used to transport power cables and other lines, with the advantages of corrosion resistance, weather resistance and so on.
4.Metallurgical industry: used to transport metal solutions and other materials, with the advantages of corrosion resistance, wear resistance and so on.
In a word, the diameter 219 internal and external epoxy plastic-coated steel pipe is a high-performance pipe material with a wide range of application prospects. With the continuous progress of science and technology and the continuous growth of market demand, it is believed that it will have a broader space for development in the future.
