Pipe Expansion
Understanding and managing pipe expansion is critical for reliable long-term results.
PP-R pipe expands and contracts with temperature changes. Proper installation techniques account for this natural material behaviour.
Installation Guidelines
1. Fixed Point Support
Install fixed supports at strategic locations to control expansion.
2. Expansion Loops
Use natural pipe routing to accommodate thermal movement.
3. Sliding Supports
Allow controlled movement between fixed points while maintaining alignment.
4. Compensation Bends
Use directional changes in the pipe run to absorb expansion safely.
Pipe Expansion Guide
When supports are spaced too far apart, thermal expansion can cause visible pipe deflection. Recommended 500mm EasyBat spacing helps control movement and maintain a straighter, more stable installation in exposed or surface-mounted applications.
