Expansion Joints
PDS Solutions, Inc. (PDS) provides complete design and fabrication services of expansion joints for power generation
and industrial applications. The durable design of PDS' expansion joints are used to accommodate thermal expansion and
contraction, while relieving thermally induced stress in ductwork systems and support structures. Additionally, these
expansion joints are also utilized to reduce the transmission of mechanical vibration from adjoining equipment.
PDS offers both Metallic and Non-Metallic expansion joints. The choice between metallic and non-metallic expansion
joints and their placement depends on several factors. These include:
- expected thermal temperatures
- type of motions (axial/shear)
- operating environment corrosive/abrasive
- system effects
PDS' engineering and design accounts for the overall system and the effect on supports and adjoining equipment. As
required, a complete stress analysis and system evaluation can be performed.
The Choice:
PDS' comprehensive approach includes complete engineering, design, and fabrication services to include:
- Engineering, design, and supply
- Molded and belted type expansion joints
- Supply to suit the duct/flue configuration
- Toggle section design
- Pin plate and center tie designs
