To design a safe and reliable piping system, it is critical to select the appropriate ASME/ANSI flange. Properly chosen flanges
The primary advantages of ASME/ANSI flanges lie in their rigorous standardization, ensuring seamless interchangeability and compatibility across global piping systems.
1. The simplest way to explain what a flange is A flange is a lip. Try to grab a smooth
ANSI/ASME flanges are a foundational component in industrial piping systems, as they provide standardized, pressure-rated connections between pipes, valves, equipment,
ANSI/ASME B16.5 and B16.47 standards define standardized pressure–temperature limits for flanged piping systems. Each pressure class corresponds to a specific
ANSI/ASME flanges are the primary connection components which are used in industrial piping systems across oil & gas, petrochemical, power
ANSI/ASME flanges are built specifically for high-pressure piping systems, as they can maintain a reliable seal under demanding conditions. They
