steel structure building materials are materials often used in the construction industry. there are many ways for steel structures to exist, such as steel plates, steel pipes, and so on. to make these pipe fittings play a better role, great scientists have been continuously developing new products, and plastic-coated steel pipes are the latest pipe fitting materials. to make the use of plastic-coated steel pipes last longer, they are treated with anti-corrosion during manufacture, which increases the anti-corrosion performance of plastic-coated steel pipes.
plastic coated steel pipes and equipment are non-toxic and harmless, and will not release any poisonous gas or pollution during production, processing, or use. it is a green and environmentally friendly building pipe fitting. moreover, plastic-coated steel pipes can effectively save energy during production, and there is no special demand for water, electricity, or other materials during the production process, and the production and processing process should be as simple as possible. to ensure the service life of plastic-coated steel pipes, corresponding anti-corrosion work will be done on plastic-coated steel pipes. corrosion of pipe fittings will have a certain impact on buildings, so some anti-corrosion treatment will be carried out when producing plastic-coated steel pipes. anti-corrosion agents or anti-corrosion paint can be applied on the inside and outside of the plastic-coated steel pipe.
the main purpose of applying anti-corrosion coatings on plastic-coated steel pipes is to better protect the cathodes. when the preservative is applied to the plastic-coated steel pipe, the loop resistance on the pipe fitting will be increased, which can reduce the flow of corrosion current. however, it is not possible to protect the steel structure from corrosion by simply applying anti-corrosion agents. when applying anti-corrosion agents, it is necessary to take necessary protection for the cathode. under the effect of two layers of protection, the plastic-coated steel pipe part can be easily corroded.
