Combined with the previously mentioned strong corrosion scenarios on offshore oil platforms and splash zones, the core advantages of multi-layer petrolatum coating anti-corrosion technology are as follows: Adapted to extreme corrosive environments, it can achieve long-term protection in harsh areas such as the splash zone where the corrosion rate reaches 0.3~0.5mm/a, effectively blocking the intrusion of chloride ions, oxygen and seawater. The protection life span exceeds 30 years, which is far better than the protection period of conventional coatings. The construction threshold is low and there is no need to perform high-standard sandblasting treatment on the base material. It can be operated directly with water and adapted to complex special-shaped components, which solves the pain points of difficult construction in flanges, welds and other parts of the traditional process. The four-layer structure with excellent comprehensive performance works together. The inner layer of petrolatum material can replace the water film on the metal surface and transform the residual rust layer. The outer fiberglass shield has strong impact resistance and can effectively suppress the risk of hydrogen penetration of high-strength steel. Outstanding economy and compliance. Compared with solutions such as Monel alloy and titanium alloy sheath, the cost is lower and has been included * * Standard GB/T 32119-2023, accounting for 65% of the domestic marine special environment anti-corrosion market, and has high engineering application maturity.
