Narrative
Approximately .24 barrels of liquefied petroleum gas was released when the bellows on a relief valve failed. The failure of the bellows cannot be determined until it is analyzed by a metallurgical laboratory. A supplemental report will be submitted once the metallurgical analysis results are received. Supplemental narrative: based on metallurgical analysis, the failure of the bellows was a result of high cycle fatigue crack failure. It is suspected that cyclic cantilever bending loads on the bellows in service created the stress conditions necessary to initiate and propagate fatigue cracking. The source of cyclic stresses contributing to the fatigue crack may have been from vibrations in the attached piping or possibly from pressure fluctuations acting on the psv bellows disc. Supplemental narrative: to satify the revised PHMSA report part e question 5f. Has been updated. In addition, the estimated volume of intentional and/or controlled release/blowdown has been corrected to 0. The product was sent to a vapor combustion unit flare.
