Technical Data

Working pressure
The class rating and rated working pressure are the ways that ASME standards simplify the design process. The pressure rating is governed by the allowable stress of different material groups, class rating, and service temperature.

ASME Material Group TABLE 2-2.2 N/A TABLE 2-3.4
Material Name SS316 Brass Alloy 400
ASME CLASS Rating 2080 N/A 1500
