Gas Fitter Practice Test

For a low-pressure steam boiler, what would be the maximum steam pressure setting?

1. 30 psig

2. 25 psig

3. 10 psig

4. 15 psig

The correct answer is: 30 psig

In the context of low-pressure steam boilers, the maximum steam pressure setting is critical for ensuring safe operation and compliance with regulatory standards. A low-pressure steam boiler is typically defined as one that operates at pressures not exceeding 15 psig. However, there are specific applications and classifications where exceeding this standard may be permitted. The gas fitter's code recognizes that certain low-pressure applications can operate with a maximum steam pressure setting of up to 30 psig, which aligns with certain industrial and specialized applications. Setting the maximum steam pressure at this level allows for operational flexibility while still maintaining safety margins in the boiler design standards. It's essential to understand that while the common operating pressure for many low-pressure steam systems is often around 15 psig, the maximum allowable setting for specific low-pressure steam boilers can indeed be 30 psig, particularly in contexts where the equipment is designed to handle that pressure safely. Therefore, in the context of regulating a low-pressure steam boiler, recognizing that the maximum steam pressure setting can indeed be 30 psig is crucial for adhering to safety protocols in some specialized scenarios.
