Sealing Performance Standards
Ensuring reliable sealing through proper material selection, design optimization, standardized procedures, and regular maintenance.
1
Selection of High-Quality Sealing Materials
- Quality of sealing material directly determines sealing effectiveness
- Select specialized materials suitable for gasoline media, aging-resistant, and corrosion-resistant
- Prefer materials with excellent oil resistance, such as fluororubber and polytetrafluoroethylene
- Ensure materials can withstand long-term gasoline immersion without swelling or cracking
- Verify materials meet industry standards and strictly control procurement quality
Prevents the use of inferior materials that could affect sealing reliability and long-term performance.
2
Optimize Sealing Structure Design
- Design scientifically sound sealing structure based on tank interface type and operating conditions
- For critical sealing areas (welds, flange connections, manholes, feed inlets), employ double or combined sealing structures
- Enhance sealing redundancy for improved reliability
- Consider factors such as temperature changes and pressure fluctuations in structural design
- Reserve reasonable expansion and contraction space to prevent structural deformation
Prevents structural deformation from compromising the sealing effect under varying operational conditions.
3
Standardize Construction and Installation Procedures
- Strictly adhere to sealing construction specifications during installation
- Ensure sealing surface is flat, clean, and free of impurities, scratches, and other defects
- Control compression of sealing components during installation - avoid excessive tightness or looseness
- Ensure full contact between sealing components and sealing surface
- For welded areas, employ professional welding techniques and conduct post-weld flaw detection
Eliminates potential weld leakage and ensures consistent, reliable sealing through standardized procedures.
4
Establish a Regular Inspection and Maintenance Mechanism
- Regularly conduct water pressure tests, air tightness tests to verify sealing performance
- Promptly identify potential leakage problems through systematic testing
- During routine inspections, focus on checking sealing areas for abnormalities (oil stains, odors)
- Replace aged or damaged seals immediately upon detection
- Maintain comprehensive maintenance records and implement full-cycle management
Ensures long-term stable sealing performance through proactive monitoring and maintenance practices.
