What is the maximum safe pressure on the low-pressure side of a fuel gas regulator?

The maximum safe pressure on the low-pressure side of a fuel gas regulator is typically established to ensure that the gas distribution system operates effectively and to prevent any potential hazards. In many standard applications, a maximum safe pressure setting of 15 psig is commonly accepted. This threshold is important for maintaining the integrity of the piping system and ensuring safe operation of appliances that utilize the gas.

Setting a maximum pressure of 15 psig helps to prevent overpressure conditions that could lead to leaks or failures in the system. This standard is often based on industry guidelines and safety regulations designed to protect users and infrastructure. Choosing a value that aligns with commonly accepted practices ensures compliance with safety standards.

In contrast, values such as 10 psig, 25 psig, or 30 psig are generally considered outside standard practices for the low-pressure side of fuel gas regulators, as they either fall below the functioning range for effective operation or exceed the safety limits set to avoid risks associated with higher pressures.
