Scope

Expansion-joint planning planning only. Manufacturer instructions, joint travel, conduit type, supports, and field temperature govern actual settings.

Lookup table

Estimate PVC expansion-joint travel and midpoint setting source links from run length and temperature change examples.

Scroll sideways to keep row labels aligned with hidden columns.

Lookup basis uses the same PVC thermal movement arithmetic with midpoint travel examples; manufacturer joint setting instructions govern field application.

Notes
  • Check table values for preliminary lookup and arithmetic checks only.
  • Confirm equipment ratings, product markings, installation conditions, utility requirements, and the local authority requirements before design or field use.
