Combined with the previously mentioned background that acidic water tanks contain H₂S, ammonia and other strong corrosive media and are inflammable and explosive high-risk working conditions, the clamp-injection pressure sealing method is the most suitable emergency repair method. The core advantages and adaptability are as follows: 1. Core adaptation advantage: no need to stop production and start fire: There is no fire or emptying of the medium during the entire process, which avoids the high risk of spontaneous combustion of ferrous sulfide in the acidic water tank and poisoning due to H₂S leakage, and will not cause downtime losses for upstream and downstream devices. Strong working condition compatibility: It can operate under normal working conditions under pressures within 5MPa, and is suitable for strong corrosive media such as acidic water and sulfur-containing oil and gas. The sealing validity period after repair can be several months to several years. High work efficiency: For common perforation locations such as tank walls and welds, sealing can be completed within a few hours, which is much faster than the construction period of traditional replacement repair welding. 2. Applicable Boundary Description This method is an emergency repair measure and is only suitable for scenarios with small and medium-sized perforations and non-structural large-area cracking. ； If a large area of the tank is corroded and unstable, the medium needs to be replaced first, and then polymer composite materials are used for permanent repair. 3. Compliance precautions Operators must hold qualifications for pressure sealing operations, prepare special safety plans in advance, detect the concentration of toxic and harmful gases on site throughout the operation, and establish a special ledger for regular tracking and testing after repairs.
