What is the code that require a Pipe Hydro Test Package?

The code that typically requires a Pipe Hydro Test Package is the ASME B31.3, which governs the design and construction of process piping. This code mandates hydrostatic testing as a means to verify the integrity and leak-tightness of piping systems. Additionally, other codes such as ASME B31.1 for power piping may also have similar requirements. Compliance with these codes ensures safety and reliability in piping systems under operational conditions.
