Anti-Vibration Clamps, incl. DamperX™ and ThermaGlide™

Field-proven designs to control vibration and allow thermal growth in piping systems

Using decades of experience in vibration design and troubleshooting, we have developed a range of anti-vibration clamps for piping systems in vibratory service. The clamps are suitable for systems subjected to demanding shaking forces typically encountered in the following applications:

  • Pulsating flow in:
    • Reciprocating compressor service
    • Reciprocating pump service
  • Two-phase flow systems
  • Piping with significant flow-induced turbulence
  • Slug flow
Overview

Our anti-vibration clamps provide unique features to balance different requirements for your piping system designs:

Vibration control

Piping systems that may experience vibration require robust supports that can withstand shaking forces and prevent fatigue failures.

All of our clamps provide the necessary stiffness to restrain vibratory movement while also resisting vibratory loosening of the support bolts, ensuring a safe and reliable operation.

Vibration damping

Our DamperX clamps provide a unique combination of stiffness and damping for applications with high vibration risk, resulting in a significant reduction of resonant piping vibration compared to other industry lining materials.

Thermal growth

Many piping systems also require flexibility to grow with thermal input, which often competes with the need for a stiff vibration design. To address these competing requirements, Wood has developed ThermaGlide™ anti-vibration clamps that allow for thermal piping movement while also providing exceptional vibration support.

Height adjustability, corrosion control and ease of inspection

Our anti-vibration wedge clamps offer superior pipe height adjustability at installation and provide ease of corrosion inspection over the life of your facility, in addition to excellent vibration control and the ability to accommodate thermal growth, when required.
