There are times when failure of the smallest components can create the biggest problems. In fact, problems that are so significant that they can cause injury or even death. An example of this are zinc-plated steel compression springs used in release valves for liquid propane (LP) applications.
These valves have been engineered to release gas when the pressure of the LP tank gets beyond a certain point. But when the spring is not operating correctly, gas can be continuously released. This creates a highly flammable environment, which can turn rapidly into a fire or explosion.
This engineering report will discuss how to solve the hydrogen embrittlement phenomenon, how to avoid multimillion dollar lawsuits, how to do thorough analysis to minimize risk and the advantages of using stainless steel compression springs in LP valve applications.
