What is the test pressure for an air cooled NH3 system?

The test pressure for an air-cooled ammonia (NH3) system is designated at 300 psi. This pressure is crucial for ensuring that the system can safely handle operational pressures while providing an adequate margin for safety when testing for leaks and structural integrity of the piping.

Typically, the test pressure is set at a level that exceeds the normal operational pressure to allow for a thorough assessment of the system's strength and to identify any weaknesses that might be present in the material or joints. Setting the test pressure at 300 psi aligns with industry best practices, ensuring that any potential failures can be detected before the system is placed into operation. The choice of test pressure also reflects considerations regarding the materials used in the construction of the system and the safety regulations governing high-pressure piping systems.
