Partial plugged tapping point creates error in PV measurement. Note Organe condition on scale.
Blocked tapping point = zero PV measurement. Note Red condition on scale.
Before drilling out tap, isolation valve is closed. Where is pressure behind isolation valve relieved and proof of isolation valve sealing confirmed?
Plug removed under pressure releases small toxic process material.
Manual drill tool attached. Isolation valve is open. How secure is manual drilling tool gland?
