Piping components must withstand what level of hydrostatic test?

The correct option indicates that piping components must withstand a hydrostatic test of four times the rated working pressure without experiencing structural failure. This is a critical safety standard in the design and testing of gas piping systems.

Hydrostatic testing is performed to ensure the integrity and safety of piping systems, especially in applications involving high-pressure gases like compressed natural gas (CNG). By requiring the components to endure a pressure that is four times their rated working pressure, regulators aim to confirm that the materials can handle extreme conditions and operate safely under normal circumstances. This adds an essential margin of safety, accounting for potential fluctuations in pressure during operation and ensuring that even the worst-case scenarios do not lead to catastrophic failures.

This rigorous testing requirement helps to prevent leaks and failures that could pose serious safety risks, including potential explosions or the release of hazardous gas into the environment. Overall, the standard ensures compliance with rigorous safety protocols in the industry, protecting both personnel and the surrounding community.
