Gas Regulator Failures

Metallurgical failure analysis was requested after a pressure regulator and valve on a helium tank was involved in an oilfield accident.  J.E.I. Metallurgical, Inc. was asked to determine if a design defect or any damage to the regulator played a part in the subject accident.  The necessity of warning labels for the regulator was also considered.  Visual and x-ray examinations were performed on the regulator. No obvious design or manufacturing defects were revealed.  The subject accident was determined to have occurred as a result of improper usage of the helium valve.
