Inner epoxy outer polyethylene anticorrosive steel pipe is a new type of anticorrosive steel pipe, its inner wall is coated with epoxy resin powder, and the outer wall is coated with polyethylene, which has excellent anti-corrosion performance and mechanical properties. In recent years, this kind of anti-corrosion steel pipe has been widely used at home and abroad. Outer polyethylene inner epoxy plastic-coated steel pipe
The manufacture of inner epoxy outer polyethylene anticorrosive steel pipe needs to go through multiple steps. First of all, the surface treatment of the steel pipe should be carried out, including rust removal, degreasing, decontamination, etc., to ensure the adhesion and service life of the coating. Then, the epoxy resin powder coating is applied, and the thickness and uniformity of the coating should be controlled during the coating process to ensure the anti-corrosion effect. Finally, the thickness and uniformity of the polyethylene coating should also be controlled.
The performance characteristics of inner epoxy outer polyethylene anticorrosive steel pipe are mainly manifested in the following aspects. First of all, it has excellent anti-corrosion properties, which can effectively prevent the erosion of various chemicals and prolong the service life of pipelines. Secondly, it has high mechanical strength and wear resistance, and can withstand large pressure and friction to ensure the safe operation of the pipeline. In addition, its surface is smooth, not easy to accumulate dirt, easy to clean, and can ensure the cleanliness and hygiene of the inside of the pipe.
In terms of application, the inner epoxy outer polyethylene anticorrosive steel pipe is widely used in petroleum, natural gas, chemical industry, urban water supply and drainage and other fields. For example, in the field of oil and gas, due to the presence of corrosive gases such as hydrogen sulfide in natural gas, ordinary steel pipes are susceptible to corrosion, while the inner epoxy outer polyethylene anticorrosive steel pipe has excellent anti-corrosion performance, which can effectively prevent the occurrence of corrosion and ensure the safe operation of the pipeline. In the field of urban water supply and drainage, the inner epoxy outer polyethylene anticorrosive steel pipe also has a long service life and good durability, which can reduce the replacement frequency and maintenance cost of the pipeline.
In a word, the inner epoxy outer polyethylene anticorrosive steel pipe is a pipe material with excellent performance and wide application. Its emergence has provided strong support for the development of oil, natural gas, chemical industry, urban water supply and drainage and other fields. In the future, with the continuous progress of technology and the continuous expansion of application fields, the application prospect of inner epoxy outer polyethylene anticorrosive steel pipe will be broader.
