The events following rupture of a pipeline containing gas at high pressure are very similar to those following rupture of the diaphragm in a simple shock tube. A description of the decompression wave resulting from such a rupture, and its rate of propagation in natural gases is the primary purpose of this paper. A computer program is written to calculate decompression wave velocities. The required thermodynamic properties are calculated using the Soave‐Redlich‐Kwong (SRK) equation of state and the results of computed wave velocities are presented and compared to values observed in the decompression zone of a shock tube.
