Ptc 192 — Asme
ASME PTC 19.2 (Performance Test Codes) is a "General" supplement document that provides essential standards for Pressure Measurement. It serves as a foundational guide for engineers to accurately determine pressure values during performance tests of mechanical equipment, particularly in power generation.
- Perform a "Line Walk": Physically trace every impulse line for the critical pressure points. Is the slope correct? Is the valve weeping? Is the seal pot filled?
- Calculate the Static Head: For differential pressure (DP) level or flow, measure the exact vertical distance between the taps and the transmitter. Do not guess the "center of pipe" distance. Use a laser level.
- Write a Pre-Test Procedure: PTC 19.2 requires that you blow down (purge) the impulse lines to ensure they are filled with the correct phase (liquid vs. vapor) immediately before the test.
: It provides uniform rules for the planning, execution, and reporting of pressure measurements to ensure results are consistent across different facilities. Instrument Guidance asme ptc 192
