What does the term W.O.G. signify in relation to piping systems?

The term W.O.G. signifies "Water, Oil, Gas" in relation to piping systems. This designation is commonly used in the context of valves, fittings, and other components that are compatible with these three types of fluids. When products are labeled as W.O.G. rated, it means that they have been tested and certified for safe and reliable use with water, oil, and gas.

Understanding this terminology is essential for pipefitters, as it helps ensure that the appropriate materials and components are used for specific applications, minimizing the risk of leaks or failures in the system. Proper knowledge of W.O.G. ratings also informs decisions about the type of piping systems to install based on the particular fluids that will be transported.
