Crude-Oil Storage Tanks

The working environment of petrochemicals is special, and high-temperature corrosive media can accelerate the corrosion of steel substrates, causing the leakage of toxic and harmful substances as well as flammable and explosive substances, resulting in economic losses and causing great impact on the production of the petrochemical enterprise.

Industry BackgroundRequirement Analysis

  • The working environment of the equipment is harsh, with high temperature, high pressure, humidity, acidic or alkaline environment, and petrochemical equipment requires a large amount of metal materials to be made, making corrosion problems difficult to avoid.

  • Anti corrosion requirements: weather resistance, water resistance, salt spray resistance, chemical atmosphere resistance, UV resistance, acid rain resistance.

  • Improve the service life of equipment, reduce maintenance and repair costs, and minimize environmental pollution to ensure the sustainable development of the petrochemical industry.

Product ApplicationCore Requirements

  • Ultra-high weather resistance, fluorine resin molecular structure contains fluorine - carbon (F-C) bond energy as high as 485.6KJ/mol, is the strongest known organic chemical bond, much larger than the ultraviolet radiation energy of 411KJ/mol, so the ultraviolet radiation energy is not able to break the connection of the F-C bond, to ensure that the film of ultra-high weather resistance.

  • Superb corrosion and chemical resistance, maximum structural integrity and tightness. Fluorocarbon resin molecular structure provides excellent adhesion, corrosion resistance, high self-cleaning, chemical resistance and stain resistance to the paint film.
