To predict the effect of hydrogen gas tank explosion on a nearby pipeline, air pressure rise and velocity on a pipeline after a strong explosion is evaluated first. Then, bending of an initially straight pipe is calculated. This bending amplitude was further scrutinized at various exploded masses of hydrogen, distances measured from the explosion center to the pipeline, and thicknesses of steel pipeline walls. (R2) The proposed analytic approach provides a conservative estimate of the worst-case accident scenario of an instantaneous explosion of a large hydrogen mass leading to formation of a shock wave. It can be useful for plant engineers to evaluate risks associated with pipelines under the presumed explosion scenario of not only hydrogen, but also any other fuel types.
