The ASME PTC 19.11 performance test code is the global gold standard for sampling, conditioning, and analyzing steam and water in power generation facilities. Maintaining high purity levels in steam and water loops is critical for preventing catastrophic equipment failures. This comprehensive guide covers the purpose, core requirements, sampling principles, and practical application of ASME PTC 19.11. What is ASME PTC 19.11? Asme Ptc 19.11 Pdf
Before analysis, the sample must be conditioned to safe and stable parameters. This section details the critical components of a conditioning panel: sample coolers, pressure reducers, flow meters, filters, and temperature gauges. The standard includes specific performance requirements. For instance, the conditioning system should deliver samples to analyzers at a pressure of about 2 kg/cm² and a temperature of 25°C (or a preset temperature with a tolerance of ±1°C). The design of the sample coolers—which handle high-pressure and high-temperature steam and water—must meet the standard's safety requirements.
is the industry-standard "Instruments and Apparatus" supplement that specifies how to sample, condition, and analyze water and steam within a power cycle. Maintaining high purity levels in steam and water
If the sampling velocity is too high or too low, a disproportionate amount of liquid droplets or solid particles will enter the probe, skewing the analysis. 2. Sample Conditioning
