Routine Inspection: Regularly inspect the flange's appearance for cracks, deformation, or other damage. Check the sealing surfaces for wear or scratches; minor damage can be repaired. Ensure all connecting bolts are tightened to prevent leaks due to loosening.
Cleaning and Maintenance: Clean the flange surface promptly to remove dirt and impurities and prevent corrosion. Use neutral detergents for cleaning; avoid using strong acids or alkalis to prevent damage to the flange surface. For flanges made of special materials (such as stainless steel flanges), it is recommended to use a specialized protective agent.
Seal Maintenance: Seals are crucial to the flange's sealing performance and should be regularly inspected for aging and wear. Replace any damaged or aged seals promptly. When installing new seals, ensure they are correctly positioned to avoid misalignment or twisting, ensuring a proper seal.
Environmental Control: Flanges should be stored in a dry, well-ventilated environment, avoiding prolonged exposure to moisture or corrosive gases. If this cannot be avoided, measures such as applying anti-corrosion paint or using protective covers can be taken to extend the flange's service life.
