Pendulum supports: flexible support for pipelines

Pendulum supports enable flexible yet secure support of pipelines. They reliably compensate for thermal expansion, vibrations, and structural settlement, thereby protecting both the pipeline and adjacent components from mechanical stress.
Thanks to their flexible support characteristics, swivel mounts are commonly used in industrial plants, power stations, and pipeline construction—anywhere dynamic influences must be managed without compromising safety and structural stability.

RATEC pendulum supports brace pipelines via two articulated struts while allowing freedom of movement. They are typically used on risers, where the pipe clamp sits on brackets on the steel structure via the struts and compensates for thermal expansion, vibration and settlement. We design each pendulum support individually for your pipeline, in all common materials and, on request, also in an ATEX-compliant version.

How pendulum supports work

A pipe clamp is mounted on the pipeline. From it, two struts run diagonally to brackets on the steel structure, on the wall or on the floor. Because the struts are articulated at both ends, they can swing: if the pipeline shifts, the struts follow the movement instead of blocking it. At the same time, they support the pipeline securely. The length of the struts allows the pipeline position to be precisely adjusted during installation.

When pendulum supports are the right choice

Pendulum supports are used wherever a pipeline needs to move but still must be securely supported. Typical cases are:

  • Risers: Vertical pipelines expand in height when temperatures change. The struts compensate for this.
  • Settlement: If a foundation or component settles, the support position shifts. Pendulum supports absorb this movement.
  • Vibration: Operational movements are absorbed without creating stresses in the pipeline and steel structure.

Pendulum supports have proven their worth in industrial plants, power stations and pipeline construction.

Part of a complete pipe support system

Pendulum supports work together with the other support points:

What matters during design

  • Pipeline: pipe type, diameter, insulation, weight.
  • Movements: thermal expansion, vibration, expected settlement.
  • Environment: corrosion, temperature, hazardous area.
  • Connection: steel structure, wall or floor, available space for the struts.

Customized by RATEC

RATEC is at home in the bulk materials sector and manufactures in its own plant in Carinthia, certified to ISO 9001, EN 1090-1 and ISO 3834-2. Each pendulum support is custom-made for your pipeline; the photos on this page show examples from customer projects. You can find an overview of all designs under Pipe supports.

Frequently asked questions

If a foundation settles or part of a building moves, a rigid support would put the line under stress or lift it. With a pendulum support, the jointed struts pivot with it and follow the movement, so no additional stresses occur in the pipe and flanges. RATEC designs strut length and joints to match the expected movements of your line.

Pendulum supports are available in all common materials, such as stainless steel, galvanized steel, or aluminum, with optional coating. The choice depends on the environment, corrosion, and the pipe material. RATEC selects the right material and can also supply ATEX-compliant or vibration-damping versions on request.

Common applications include riser pipes and multi-directional lines in industrial plants, power stations, and pipeline construction. They also compensate for movement in settling buildings or foundations. RATEC manufactures pendulum supports for connection to steel structures, walls, or floors.

A pendulum support is a movable pipe support where the pipe clamp is supported on brackets via two articulated struts. This allows the line to accommodate thermal expansion, vibrations, and settlement without creating stress. RATEC pendulum supports feature length-adjustable struts and are custom-engineered for each individual line.
