Incident Date
Describe the incident, including corrective steps taken and their result.
During maintenance on a breakaway fitting, a review of the pressure rating of the adapter fitting connecting the pipe to the breakaway found the adapter to be under rated for the design pressure. While the male straight-thread side of the "standard" fitting was rated to 7700 psig, the female compression-tube end of the same fitting was rated to only 4900 psig. The adapter was replaced with a fitting of increased wall thickness meeting the design pressure rating.
Lessons Learned
Consider design review of all adapter fittings.
