Thermal expansion occurs when piping materials expand or contract due to temperature changes. This can cause significant stress within the piping system, potentially leading to deformation, misalignment, or even failure if not properly managed through stress analysis and design techniques like expansion loops, joints, and anchors.
Common solutions include:
- Adding expansion loops, joints, or bends to absorb thermal expansion
- Optimizing support placement and design to reduce stress concentrations
- Adjusting the layout to minimize unnecessary loads
- Using flexible connectors to accommodate movement
- Reinforcing high-stress areas or adjusting wall thickness
Neglecting piping stress analysis can lead to:
- Pipe failures, such as leaks, ruptures, or breakages
- Equipment damage due to excessive loads or misalignment
