Waste Oil Tank Sealing Technology
Comprehensive guidelines for effective sealing of waste oil storage tanks to prevent leaks and ensure environmental safety
1
Selection of Suitable Sealing Materials
- Select sealing materials according to the type of connection and the characteristics of the waste oil
- Prioritize high-quality materials that are corrosion-resistant, oil-resistant, and anti-aging
- Use dedicated rubber sealing rings, PTFE gaskets, and oil-resistant sealants
- Ensure that the material is chemically compatible with the stored waste oil
- Avoid swelling and cracking due to material incompatibility
- Ensure the material is suitable for the working temperature and pressure environment
- Guarantee long-term sealing stability and prevent leakage problems caused by material failure
2
Cleaning and Pre-treatment of Connection Structures
- Thoroughly clean the connection surface before sealing
- Remove oil, rust, impurities, and aged residual sealant
- Ensure that the connection contact surface is flat and smooth
- Eliminate scratches, dents, or burrs on the contact surface
- For flange interfaces, check the flatness of the sealing surface
- Grind the sealing surface if necessary to ensure proper contact
- For threaded interfaces, clean the threads to ensure a tight fit
- After pretreatment, keep the interface dry and clean
- Create favorable conditions for sealing material adhesion
3
Standardize Installation Procedures
- When installing seals, ensure accurate positioning
- Avoid misalignment or twisting of the contact surfaces
- Ensure the sealing ring is fully embedded in the sealing groove
- Prevent edge lifting of the sealing material
- When tightening flange interfaces, use a symmetrical and even tightening method
- Ensure even pressure distribution across the sealing surface
- Prevent localized loosening or overtightening that could lead to seal failure
- For threaded interfaces, wrap with special sealing tape
- Apply an appropriate amount of oil-resistant sealant to enhance the sealing effect
- After installation, check the interface closure to ensure no gaps or looseness
4
Regular Maintenance and Leakage Checks
- Establish a regular inspection system for all sealing points
- Focus on checking for signs of leakage at the interface sealing points
- Check whether the seals are aged, hardened, or damaged
- Replace aged sealing materials promptly based on usage
- Prevent material fatigue from affecting sealing performance
- After loading, unloading, or tank relocation, additionally check the sealing status
- If any potential leakage is found, immediately stop operations
- Address any identified issues promptly and thoroughly
- Ensure continuous and reliable sealing performance
