Decayed tube skin thermocouples must be monitored for drift and replaced during scheduled unit turnarounds.

API RP 556 is specifically designed for that transfer heat to liquids or gases within tubular coils.

The BMS is the dedicated safety system responsible for executing the safe start-up, monitoring, and shutdown of burners. API RP 556 aligns closely with safety standards like ISA-84 / IEC 61511, outlining:

Safety instrumented functions (SIFs) within the BMS must be tested at regular intervals to uncover dangerous undetected failures. This includes testing flame scanners, emergency shutdown valves (ESDV), and pressure switches. api rp 556 pdf
