A giant flange (commercially referred to as a large diameter flange) is an oversized mechanical connecting ridge, lip, or rim designed to securely join, seal, and reinforce massive pipes, valves, and pressure vessels. Typically defined by industry standards like ASME B16.47, these specialized components are engineered for massive pipelines exceeding 24 inches (600 mm) and scaling up to 200 inches in outer diameter.
They provide a highly secure, non-permanent, and reversible connection that allows heavy industrial infrastructure to be easily disassembled for cleaning, inspection, or repairs. How a Giant Flange Works
A giant flange acts as a mechanical sealing interface that translates immense external mechanical force into uniform internal containment. It functions through three core steps:
