Pipe Expansion Joint Flange Data

Flanges for Stainless Steel Expansion Joints
 

Stainless Steel Flanges on Single Pipe Metallic Expansion Joints

 

The summary of flange data listed below is offered as a guide to assist designers in selecting the most economical flanges for their piping system. When selecting a bellows from the catalog data pages that will have flanged connections, it is important that the system designer confirm that the flanges he has selected have an adequate pressure rating for the given system temperature. There may be instances where the bellows has a higher pressure rating than does the flange at the design temperature.

The service temperature ratings shown below have been taken from Taylor Forge Catalog #571. Where elevated temperature data was not available, the service pressure ratings were obtained by down rating the ambient pressure rating in accordance with ASME Code strength versus temperature correction factors.
