Information regarding Cast Iron Pipe Flanges can be found in which standard?

• A. ASME B16.1
• B. ASME B16.5
• C. ASME B31.1
• D. ASME B16.3

Answer: (A)

The correct standard for information regarding Cast Iron Pipe Flanges is indeed ASME B16.1. This standard specifically focuses on the markings, dimensions, tolerances, and materials of cast iron flanges, which are crucial for ensuring proper fit and function in piping systems. ASME B16.1 covers flanges for gray iron and ductile iron, establishing guidelines that help engineers and manufacturers produce components that meet the necessary safety and performance requirements.

In contrast, ASME B16.5 deals with pipe flanges and flanged fittings made from materials such as carbon steel and stainless steel, which do not cover cast iron. ASME B31.1 is a code for power piping that outlines the requirements for the design and construction of piping systems but is not specifically focused on flanges. ASME B16.3 pertains to the dimensions and materials for malleable iron threaded fittings, which is also outside the realm of cast iron pipe flanges. Thus, ASME B16.1 is definitively the resource that provides the relevant information for cast iron pipe flanges.
