I. Coating materials and characteristics

Internal and external wall coated steel pipe is corrosion resistant, mainly due to its special coating materials. The inner layer is usually made of plastic materials such as polyethylene (PE) or polypropylene (PP). These materials have excellent chemical inertness and do not react with chemicals in water, thus effectively protecting the inside of the pipe from corrosion. The outer layer is made of weather-resistant materials such as epoxy resin (EP) or polyvinyl chloride (PVC). These outer layer materials can resist the erosion of the external environment, such as ultraviolet rays, temperature changes and chemical attacks, to ensure that the pipeline can maintain good performance in a variety of environmental conditions.

II. corrosion resistance verification

The corrosion resistance of inner and outer wall plastic coated steel pipe is not only recognized in theory, but also fully verified in practical application. Through rigorous laboratory tests and long-term on-site monitoring, the coating of this pipe has been proven to effectively resist corrosive substances in water quality. Even in water containing high concentrations of minerals, acidic or alkaline substances, the internal and external wall coated steel pipe can keep its surface smooth and clean, preventing the accumulation of scale and corrosion products and ensuring the safe and efficient operation of the water supply system.

Studies have shown that the water supply system using internal and external wall coated steel pipe still maintains good corrosion resistance over many years of use. This not only reduces the maintenance cost of the pipeline, but also extends the service life of the pipeline, to avoid water leakage and water pollution caused by corrosion of the pipeline.

III. the actual application performance

In practical application, the corrosion resistance of internal and external wall coated steel pipe has been generally recognized by users. Many urban and industrial water supply systems have adopted this pipe as the main water pipeline. After years of actual operation, these systems in the internal and external wall coated steel pipe performance, there is no corrosion caused by water leakage or pipe damage. This pipe is not only corrosion-resistant, but also has good abrasion resistance and high pressure resistance, can withstand the impact of high-flow water and high water pressure, to ensure the long-term stable operation of the water supply system.

IV. a wide range of applications

Internal and external wall coated steel pipe for water supply is not only suitable for ordinary water distribution system, but also widely used in chemical industry, petrochemical industry and other fields that require high corrosion resistance. In these areas, the pipeline needs to withstand a variety of highly corrosive chemicals. With its excellent corrosion resistance, internal and external wall coated steel pipe provides reliable anti-corrosion solutions for these industrial facilities, ensuring the safety and stability of the production process.
