What type of testing is usually performed to verify the integrity of pressure pipes?

Hydrostatic testing is the preferred method for verifying the integrity of pressure pipes because it involves filling the piping system with water, and then pressurizing it to a predetermined level above its normal operating pressure. This process enables the detection of any leaks or weaknesses present in the pipe material or joints. It is highly effective as water, being incompressible, allows for precise monitoring of the pressure levels over time to identify any drop in pressure that would indicate a leak.

In addition to revealing leaks, hydrostatic testing ensures that the pressure piping system can withstand the forces of the fluids it will transport under normal operation, thereby confirming its operational safety. This testing method is widely accepted and used in the industry for ensuring the performance and safety of pressurized systems.
