Component Specifications

Definition
A flange is a mechanical component designed to join sections of pipe or connect pipe to a pressure vessel, valve, or other equipment. It consists of a flat, circular ring with bolt holes around its perimeter. Flanges are paired with matching flanges on adjacent components and secured with bolts, compressing a gasket between them to create a leak-proof seal. They facilitate assembly, disassembly, and maintenance in industrial piping systems, allowing for easy access for inspection or modification. Common in outlet connections of machines, flanges ensure secure, standardized interfaces that withstand operational pressures and temperatures.
Working Principle
Flanges work by providing a mating surface for connection between two components. When bolted together, they compress a gasket placed between the flange faces, creating a tight seal that prevents leakage of fluids or gases. The bolt load distributes pressure evenly across the gasket, maintaining integrity under varying thermal and mechanical stresses. Flanges align components precisely, ensuring proper flow and structural support in the system.
Materials
Common materials include carbon steel (ASTM A105), stainless steel (ASTM A182 grades like 304, 316), alloy steel, ductile iron, or non-metallic options like PVC for specific applications. Material selection depends on factors such as corrosion resistance, temperature, pressure, and fluid compatibility.
