What does the data plate on an ASME tank not specify?

1. Working pressure

2. Test date

3. Tare weight

4. Manufacturer details

The correct answer is: Tare weight

The data plate on an ASME (American Society of Mechanical Engineers) tank provides crucial information for safe operation and compliance with regulations. It typically includes important details such as the working pressure, which indicates the maximum pressure that the tank is designed to safely contain. It also specifies the test date, which is essential for determining when the tank was last inspected and certified for use, ensuring ongoing safety and performance. Moreover, the manufacturer details listed on the data plate identify the company responsible for producing the tank, which is important for accountability and maintenance purposes. Knowing the manufacturer can help in sourcing parts or service if needed. The tare weight, however, refers to the weight of the tank when it is empty. This detail, while relevant in some contexts, is typically not specified on the data plate. Instead, other documentation or markings on the tank may provide that information. Therefore, while the other elements on the data plate are critical for ensuring the tank’s operational safety and compliance, the tare weight is not generally included.
