1. Select High-Quality Sealing Materials
The quality of the sealing material directly determines the sealing effect. Specialized materials suitable for gasoline media, resistant to aging, and corrosion-resistant must be selected. Prioritize materials with excellent oil resistance, such as fluororubber and polytetrafluoroethylene (PTFE), which can withstand long-term gasoline immersion and avoid problems such as swelling and cracking. Simultaneously, ensure that the materials meet industry standards, strictly control procurement quality, and eliminate the use of inferior materials that could affect sealing reliability.
2. Optimize Sealing Structure Design
Design a scientifically sound and reasonable sealing structure based on the tank's interface type and operating conditions. For critical sealing areas such as tank welds, flange connections, manholes, and feed inlets, adopt double or combined sealing structures to enhance sealing redundancy. The structural design must consider factors such as temperature changes and pressure fluctuations, reserving reasonable expansion and contraction space to prevent structural deformation from compromising the sealing effect.
3. Standardize Construction and Installation Procedures
Strictly follow sealing construction specifications during construction to ensure the sealing surface is flat, clean, and free of impurities, scratches, and other defects. Control the compression of the sealing element during installation, avoiding excessive tightness or looseness, and ensuring full contact between the sealing element and the sealing surface. For welded areas, professional welding techniques are employed, and flaw detection is performed after welding to eliminate potential leaks.
4. Establish a Regular Inspection and Maintenance Mechanism
Regularly conduct water pressure tests and airtightness tests to test the sealing performance of the storage tank and promptly identify potential leaks. During daily inspections, focus on checking the sealing areas for abnormalities such as oil stains and odors. Replace aged or damaged seals promptly, and maintain maintenance records to form a full-cycle management system, ensuring long-term stable sealing performance.
