Standard Practice for Natural Gas Sample-Handling and Conditioning Systems for Pipeline Instrumentation
 N D5503

Annotation

This practice covers sample-handling and conditioning systems for typical pipeline monitoring instrumentation (gas chromatographs, moisture analyzers, and so forth). The selection of the sample-handling and conditioning system depends upon the operating conditions and stream composition.

This practice is intended for single-phase mixtures that vary in composition. A representative sample cannot be obtained from a two-phase stream.

The values stated in SI units are to regarded as standard. The values stated in English units are for information only.

This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

Общепринятая практика для систем обработки образца и создания условий природного газа для инструментовки трубопровода

Эта практика покрывает обрабатывающие выборку и системы кондиционирования для типичного конвейерного контрольного инструментария (газовые хроматографы, влажность анализаторы, и т.д). Выбор обрабатывающей выборку и системы кондиционирования зависит от потокового состава и условий эксплуатации.
