Characteristics of Bolted Flange Assemblies
Bolted flanges connections - Characteristics and components

Bolted flange assemblies must meet three main functional requirements:

• ensure the structural continuity of the equipment to enable efficient transmission of forces between the various components of a system;

• to facilitate the assembly and disassembly of the joint;

• guarantee the tightness of the joint, thereby ensuring the continuity of the pressure barrier.

To meet these three requirements, a bolted flange joint consists of flanges, a gasket, and bolts used to tighten the assembly (Figure 1 ).
