Asme Ptc 19.11 Pdf
If cooling water fails, sample temperatures spike instantly. Mechanical thermal shut-off valves automatically close the sample line if temperatures exceed 49°C (120°F), protecting personnel and expensive sensors.
ASME PTC 19.11-2008 (R2018) provides essential guidelines for sampling, conditioning, and analyzing steam and water in power cycles to ensure accurate chemical analysis and prevent boiler/turbine damage. It covers the full sampling process, including requirements for isokinetic sample probes, cooling systems, and analysis methods for parameters like pH and conductivity. You can purchase the official document on the ASME website.

Ensuring that oxygen scavengers and pH-control chemicals are at optimal levels. Asme Ptc 19.11 Pdf
Long runs increase lag time and encourage chemical deposition or reactions within the sample tubing.
For steam samples containing moisture or particulates, the code mandates isokinetic probes. This means the velocity of the fluid entering the probe nozzle must exactly match the velocity of the process stream.
