What information must be on the data plate of an ASME tank?

The data plate of an ASME (American Society of Mechanical Engineers) tank is required to include specific critical information to ensure safe operation and compliance with regulations. The maximum allowable working pressure is a key factor because it indicates the highest pressure at which the tank can operate safely. This pressure limits the operational parameters and is essential for determining safe practices in the storage and handling of the materials contained within the tank.

This requirement is part of standard safety precautions to prevent potential hazards such as overpressure incidents, which could lead to catastrophic failures. Understanding this information is crucial for anyone working with or around ASME tanks, as it directly impacts safety measures and operational protocols.

The other information mentioned, such as the type of propane used, distance from the nearest water source, and temperature rating, may be relevant in certain contexts but are not mandated as part of the essential information on the data plate of an ASME tank. The focus on pressure ensures that operators prioritize the most significant safety factor when utilizing these tanks.
