ASME B16.34: Valve Pressure-Temperature Ratings

ASME B16.34 specifies pressure and temperature ratings for valves in different classes, ranging from 150 to 4500, guiding their safe use across varying operational conditions. It categorizes valve materials into groups based on their properties, such as carbon steel, stainless steel, and various alloys, to ensure compatibility with specific pressure and temperature conditions. This system facilitates the selection of appropriate valve materials for safety and efficiency in applications, considering factors like corrosion resistance and strength under pressure.

ASME B16.34 For Valves

ASME B16.34 categorizes materials into several groups to standardize the application of valve materials across different temperature and pressure conditions. These groups **help in selecting the appropriate material **for valves based on operational requirements, ensuring compatibility with the fluid being handled and the environmental conditions of the application.

The material groups include various grades of carbon steel, stainless steel, alloy steel, and non-ferrous metals, each chosen for their specific properties like strength, corrosion resistance, and temperature tolerance.

ASME B16.34 mentions pipes, plates, and steel bars because it includes material specifications and grades for the manufacture of valve parts. These materials must meet specific standards to ensure that valves can safely operate under the pressure and temperature conditions for which they are rated. Including these materials helps ensure compatibility and safety across various applications in piping systems.
