Combined with the previously mentioned mechanism of high-temperature H₂ corrosion in petrochemical industry and typical accident background, targeted protection can be implemented from the following dimensions: Compliance material selection strictly follows the Nelson curve selection of API RP 941 (5th edition), giving priority to chromium-molybdenum steel containing Cr and Mo elements to replace unstable iron carbides in carbon steel to suppress methane generation from the root and avoid hydrogen embrittlement failure. Process control controls the operating temperature and hydrogen partial pressure of the device within the safe range allowed by the material to avoid over-temperature and over-pressure operation. It also regulates the content of corrosive components such as H₂S in the medium to reduce the penetration rate of hydrogen into the metal. Manufacturing and Operations Optimization Perform standardized post-weld heat treatment (PWHT) on chromium-molybdenum steel equipment to eliminate residual stress and further improve the steel's resistance to high-temperature hydrogen corrosion. Carry out regular corrosion testing of hydrogen-facing equipment to identify potential micro-cracks and avoid failure risks similar to typical accidents. Coating protection: Apply a high-temperature anti-corrosion coating suitable for working conditions on the surface of the equipment to form a physical shielding layer, blocking hydrogen atoms from directly contacting the metal matrix, and adapting to high-temperature hydrogen exposure scenarios above 200°C.
