The Anti-earthquake Length for the Joint Revolution Bellows of Oil Tank and Pipeline

The weaker part of system for anti-earthquake, which is the joint between tank and pipeline, is studied in this paper. The static analysis method for the revolution bellows, the static analysis method for system of oil tank and pipeline and the dynamic analysis method are all used in this paper. Considering the liquid gravity, the sink of oil tank base, temperature change and the earth- quake, the determination method for the anti-earthquake length of revolution bellows are presented in this paper. It may be useful for the anti-earthquake design of the joint revolution bellows between oil tank and pipeline and may be the theoretical base for the revision of relevant standard in engineering.
