STAMP provides training and multimedia production services, we specialise in training related to valves, actuators and associated activities. The video below was produced by STAMP as a training tool to help our trainees understand and appreciate what happens when a pressure release occurs due to the failure of a threaded plug, an ever-present hazard in our industry.

Thread failure in plugs can occur for a number of reasons such as damaged threads on the male or female side, mis-matching threads or over-use of PTFE thread tape. When the failure does occur the effects can be catastrophic, the plug becomes a high velocity missile accompanied by a pressure blast capable of causing severe injury and plant damage.

In the video below we see a simulation of the effect as a threaded plug fails on a vessel pressurised with gas at only 500psi.

This simulation lets anyone involved in pressure testing or working with pressurised equipment see first hand the effects of a threaded plug failure on a vessel pressurised with gas or with a trapped air pocket.
