Girth Flanges. Girth flanges are used for mating two segments of a pressure vessel.
These parts are also widely used in shell and tube heat exchangers and other process equipment to mate various components.
There are two common kinds of girth flange such as welded hub joint, loose type (without hub).
Girth flanges are found in shell & tube exchangers for the shell and channel barrels.

From the standpoint of internal pressure and bolt loading, blind flanges, particularly in the larger sizes, are the most highly stressed of all flange types; however, since the maximum stresses in a blind flange are bending stresses at the center, they can safely be permitted to be higher than in other types of flanges.

Generally machined from a forging, these flanges are typically butt welded to a pipe. The rim has a series of drilled holes that permit the flange to be affixed to another flange with bolts.

The post Lap Joint appeared first on OTG.

]]> Lap Joint Flanges are primarily employed with lap joint stubs, the combined initial cost of the two items being approximately one-third higher than that of comparable welding neck flanges. Their pressure-holding ability is little, if any, better than that of slip-on flanges and the fatigue life of the assembly is only one-tenth that of welding neck flanges.

The post Orifice appeared first on OTG.

]]>

Orifice Flanges are widely used in conjunction with orifice meters for measuring the rate of flow of liquids and gases.

They are basically the same as standard welding neck, slip-on and screw flanges except for the provision of radial, tapped holes in the flange ring for meter connections and additional bolts to act as jack screws to facilitate separating the flanges for inspection or replacement of the orifice plate.
