When conveying media containing chloride ions, H₂S, CO₂, or acids and alkalis, ordinary steel pipes will rapidly rust due to chemical and electrochemical corrosion. Their service life is typically limited to 3-5 years, requiring frequent replacement, which significantly impacts construction.Internal anti-corrosion steel pipeline can withstand the transportation of crude oil containing H₂S, extending their service life to 30-40 years. This corrosion protection principle isolates the media from direct contact with the steel substrate, preventing corrosion reactions at the source while also preventing perforation and leakage, significantly extending their service life.
With increasing awareness of the environment, pollution issues in some industrial plants have repeatedly drawn users' attention. This is particularly true for applications involving drinking water, food fluids, and high-purity chemical raw materials. Rust and microbial adhesion can lead to contamination of the media.Internal anti-corrosion steel pipeline ensure media cleanliness through an inert protective layer. The lining itself is non-toxic, non-exfoliating, and has a smooth surface that is not susceptible to bacterial growth. It also resists reactions with acids, bases, and organic solvents, ensuring the purity of the transported media meets standards.
After a period of use, ordinary steel pipes will develop rust and scale deposits, which can reduce the inner diameter and roughen the inner wall, increasing transport resistance. This means that transport speed decreases over time. Internal anti-corrosion steel pipeline reduce energy consumption through a smooth inner lining and anti-scaling properties. Their low surface roughness makes them less susceptible to adsorption of calcium and magnesium ions in water or impurities in crude oil. They also require less frequent cleaning for long-term use, improving work efficiency and reducing labor costs.
For ambient temperature media, we have a wide variety of pipes to choose from. However, for special operating conditions, we must select the appropriate pipe based on the intended use. These include special and harsh operating conditions, such as those involving strong corrosion, particles, and high temperatures and pressures.Internal anti-corrosion steel pipeline utilize various lining solutions to adapt to these complex environments. Ensuring operational safety, extending service life, and reducing maintenance costs are also key priorities when producing internally-corroded steel pipes. We hope that every user will benefit from our steel pipe products.
