Stress Analysis of Suspended Gas Pipeline

Abstract:

Under the effect of geologic hazard, soil horizon under gas pipeline tends to subside or runoff, which may result in pipeline hanging in the air with uneven distribution of stress and consequently lead to pipe failure. In view of pipeline suspension resulted from geologic hazard and taking pipeline XX as example, software CAESAR II is used to analyze the stress of suspended pipelines with different length combined with practical and existing analysis calculation model. The critical length of suspended pipeline is obtained on the basis of the software analysis. The results with certain engineering value can provide reliable theoretical basis for practical engineering.
