What does pressure testing validate in a piping system?

Pressure testing is a critical procedure used to validate that a piping system can safely handle the pressures for which it is designed. The main goal of pressure testing is to ensure that the integrity of the piping system is intact and that it can withstand specified pressure levels without leaking or failing.

When a piping system is subjected to pressure testing, typically involving water, air, or another fluid, it simulates the operational conditions the system will face while in use. This process allows for the detection of any weaknesses, leaks, or defects in the material or connections within the system. By confirming that the system can handle the intended pressures, it ensures safe operation and compliance with applicable codes and standards.

Other aspects, like resistance to corrosion, insulation properties, and compatibility with different fluids, are important for the overall performance and longevity of a piping system but are not validated directly through pressure testing. Instead, those considerations are typically addressed through material selection, proper installation, and ongoing maintenance practices.
