What is the maximum working pressure for Type III Low Pressure Equipment?

The maximum working pressure for Type III Low Pressure Equipment is defined as being between 4 ounces of water column to 2 psi. This classification indicates the equipment is designed to safely operate below certain pressure thresholds, which helps ensure safety during its use and prevents accidents that could arise from operating at higher pressures.

In practice, this means that Type III Low Pressure Equipment is suitable for applications where very low pressure is used, which is critical for specific processes such as certain refrigeration or HVAC systems. The pressure range specified allows for safe operation while handling substances likely to be in low-pressure environments. Understanding this pressure threshold is essential for professionals working with low pressure equipment to maintain compliance with safety standards and ensure effective operation.
