Abstract:

In order to solve the corrosion problem of wharf steel piles, the work aims to conduct corrosion investigation on Chinese similar receiving terminals and optimize the long-term corrosion protection technology of steel piles. According to the research and experimental results, the protective effect of petrolatum tape and covering system (PTC) was better than that of the other two anticorrosion technologies. PTC was the best solution for corrosion protection of wharf steel pile in splashing zone. Tianjin Nangang LNG receiving terminal breaks the tradition of corrosion protection design at Chinese wharfs and it is the first case in China that PTC technology is used for corrosion protection in the initial stage of design and construction. The relevant investigation and test results can provide reference for the corrosion protection design of wharf steel piles in China.
