An Anchor Flange is important in many thrust-control systems. It is essential when protecting pipeline pumping or gas stations. Anchor Flanges are most commonly welded into the line and covered in concrete, this immobilizes the pipe at predetermined locations and transfer built-up stresses to exterior structures. Anchor Flanges combat axial movement. They bear a resemblance to a collar, once it is attached to a pipe. They prevent the pipeline from moving by typically being placed onto a section of pipeline as it makes a turn or is at a bridge crossing.
A metal pipeline is known for its inherent movement caused by the flow of liquid, as well as contraction and expansion caused by temperature changes. By locking in an Anchor Flange and securing it’s position, the forces of flow pushing against the pipe are displaced on the earth.
