Victaulic Grooved Expansion Joints
Victaulic grooved expansion joints are mechanical expansion assemblies combining grooved couplings and precision-grooved nipples to absorb axial movement, vibration, and deflection in piping systems. They enable fast installation, reduced labor, and reliable performance in wet and dry piping applications.
Overview
Victaulic grooved expansion joints consist of grooved mechanical couplings assembled in tandem with short, precisely grooved pipe nipples. This configuration provides controlled axial movement and flexibility, allowing piping systems to safely absorb thermal expansion, contraction, vibration, and minor misalignment.
Design & Construction
- Combination of grooved couplings and short grooved nipples
- Precisely machined grooves to allow full linear expansion at each joint
- Mechanical coupling system originally developed by Victaulic in 1925
- Suitable for both wet and dry piping systems
Movement & Flexibility
- Absorbs axial expansion and contraction
- Allows controlled angular deflection
- Dampens vibration within the piping system
- Reduces stress on connected equipment and supports
Victaulic Coupling Options
