This product is suitable for salt spray erosion scenarios and can be installed in coastal areas with frequent salt spray. What additional protective measures should be taken?
For installation in coastal areas prone to salt spray, three additional protective measures need to be taken: first, anti-corrosion reinforcement, applying nano level anti salt spray anti-corrosion coating on the equipment shell, focusing on strengthening the sealing interface and connection parts, enhancing the anti salt spray erosion ability, and applying anti-corrosion coating every 12 months; The second is to install protection measures, such as building salt spray shelters to avoid direct exposure of equipment to salt spray environments. At the same time, optimize the installation location of equipment and keep it away from areas with high salt spray concentrations near the sea; The third is daily operation and maintenance. Clean the equipment shell and interface every month, remove salt spray residue, check the anti-corrosion coating and sealing performance every three months, replace aging seals, and detect the corrosion of internal components of the equipment to promptly deal with corrosion hazards; Every 6 months, the purity and pressure of SF6 gas are tested to avoid gas leakage and purity decrease caused by salt spray erosion, ensuring long-term stable operation of the equipment.
