What is the testing pressure for the low side of an ammonia system?

In ammonia systems, the testing pressure on the low side is typically specified to ensure the safety and integrity of the piping. The low side of an ammonia system is subject to operational pressures that may vary, but a testing pressure of 150 psi is a standard requirement in many industry guidelines and regulations. This pressure is sufficient to ensure that the system can withstand operational stresses and safely contain ammonia during routine use.

Testing at this pressure allows for the identification of leaks or weaknesses in the system without exceeding the design limits, which is critical for safety as ammonia is a hazardous material. By establishing a testing pressure of 150 psi, technicians can verify that the system will operate reliably under the anticipated conditions.

Understanding the correct testing pressure for ammonia systems is important for compliance with local codes and industry best practices, as it minimizes risks related to leaks and ensures the system's effective operation. It also reflects the necessary emphasis on safety protocols that must be maintained when handling potentially dangerous substances like ammonia.
