This paper presents the prerequisites and main test parameters for conducting vertical gas-liquid combined tests on large towers,including test pressure,maximum liquid column height,minimum liquid column height,and design liquid column height values.Combining a design example of an ethylene tower in an ethylene plant,it demonstrates the superiority of using gas-liquid combined tests for large towers under on-site vertical conditions.Replacing traditional hydraulic tests with vertical gas-liquid combined tests can effectively reduce the weight of the tower and the load on the civil foundation.
