Balancing Port Location And Plugs
Test ports need to be placed where TAB can actually read pressure or airflow, then plugged and sealed after use.
What This Helps With
Test ports need to be placed where TAB can actually read pressure or airflow, then plugged and sealed after use.
Apprentice words: test port, static pressure hole, pitot hole, TAB plug, pressure tap
Common problem: Holes are drilled in bad locations, left open, or covered by insulation without plugs.
Check First
What Not To Do
Do not randomly drill test holes. Do not leave open holes. Do not cover ports before TAB is done.
What can go wrong: Holes are drilled in bad locations, left open, or covered by insulation without plugs.
Better Foreman Question
Where does TAB want the test port, and what plug/label do we use after the reading?
Verify With
Source to verify: TAB contractor direction, project commissioning plan
Safe wording: Exact test locations depend on TAB procedure and system layout.
