Anchor Flange

Anchor flanges are important elements in many thrust-control systems, especially those protecting pipeline pumping stations. Welded into the line and encased in concrete, they immobilize the pipe at predetermined locations and transfer built-up stresses to external structures. 

Anchor Flanges are used to anchor pipe - often when crossing streams or ravines. They are a double hub piece of steel that is put into a special holder that is part of a piling to supports the pipeline and resist loading. The anchor structure is welded to the pipe and usually embedded in concrete. 
Anchor flanges actually contain axial thermal expansion that is axial thrust in pipelines. The assumed design temperature change is 90 degrees Fahrenheit. The thrust is transferred to the anchor foundation in which the anchor is mounted. These flanges are used at crossings and points with changes in pipeline direction.
