PVC Expansion Joint Setting Table
PVC Expansion Joint Setting Table reference with assumptions and boundary notes.
Reference boundary
Expansion-joint planning reference only. Manufacturer instructions, joint travel, conduit type, supports, and field temperature govern actual settings.
Reference table
Estimate PVC expansion-joint travel and midpoint setting references from run length and temperature change examples.
| Run length (m) | Temperature change (C) | Estimated movement (mm) | Midpoint setting (mm) | Boundary |
|---|---|---|---|---|
| 10 | 20 | 10.4 | 5.2 | joint travel and field setting come from the manufacturer instructions and measured installation temperature |
| 10 | 40 | 20.8 | 10.4 | joint travel and field setting come from the manufacturer instructions and measured installation temperature |
| 30 | 20 | 31.2 | 15.6 | joint travel and field setting come from the manufacturer instructions and measured installation temperature |
| 30 | 40 | 62.4 | 31.2 | joint travel and field setting come from the manufacturer instructions and measured installation temperature |
| 50 | 40 | 104 | 52 | joint travel and field setting come from the manufacturer instructions and measured installation temperature |
| 50 | 60 | 156 | 78 | joint travel and field setting come from the manufacturer instructions and measured installation temperature |
Use notes
- Use this table for preliminary reference and arithmetic checks only.
- Confirm equipment ratings, product markings, installation conditions, utility requirements, and the local authority requirements before design or field use.
