Describe the significance of pressure testing in pipefitting.

The significance of pressure testing in pipefitting lies in its critical role in ensuring the integrity and safety of piping systems before they are put into service. This testing process is essential as it verifies that the system can withstand the operational pressures it will encounter during its lifespan without failing. By subjecting the piping to controlled pressure, potential weaknesses, leaks, or failures can be identified and addressed prior to the system being fully operational. This preventative measure protects not only the infrastructure itself but also the safety of individuals who will interact with or be in proximity to the system.

Effective pressure testing fosters reliability and compliance with industry standards and regulations, which is critical for the safety of both commercial and residential installations. Overall, it serves as a foundational step in the commissioning process of any piping system, ensuring that it will perform safely and effectively under its designed conditions.
