Rigid Hangers, Struts та Sway Braces

Constant spring supports allow vertical movements of the pipe due to thermal expansion or contraction and have a fixed load output throughout their travel range. They are used when vertical movement is high (from 50-75 mm upwards) and when stress at the pipe nozzles and equipment has to be very limited. There is a wide range of models, sizes and types in order to cover a very extensive range of loads, travels and installation configurations, being used as a hanger (above the pipe) or as a support (below the pipe).

Rigid Hangers

Rigid hangers are used to suspend pipelines from above while completely restricting vertical movement.
They are composed of rods, clamps, eye nuts, and beam attachments, ensuring stable support under tensile loads.
Rigid hangers are applied when a fixed vertical position of the pipe is required and no upward or downward movement is allowed.


Struts (Sway Struts)

Struts are rigid linear supports that restrict pipe displacement along its axis.
They can be installed vertically, horizontally, or diagonally and are capable of carrying both compression and tension loads.
Sway struts transfer these forces directly to the supporting structure, providing strong stabilization against movement.


Sway Braces

Sway braces are designed to control vibration, oscillation, and dynamic loads such as water hammer or seismic activity.
Unlike snubbers that instantly lock movement, sway braces absorb and dampen excessive displacement, reducing stress on the pipeline and equipment.
They are essential in high-risk installations where shock control and stability are required.
