Scope
GB/T 37124-2018 is the English-translated version of 进入天然气长输管道的气体质量要求.
GB/T 37124-2018 sets the quality requirements, test methods and inspection rules for gas entering long-distance natural gas transmission pipelines. It applies to treated natural gas, coalbed methane, shale gas, tight sandstone gas and coal-based synthetic natural gas carried in those pipelines.
Its normative references show the methods it relies on: gas chromatographic composition analysis, the determination of hydrogen sulfide and total sulfur, water dew point measurement and conversion from water content, particulate matter by weighing, and the calculation of calorific value, density and Wobbe index, together with sampling guidelines and the interchangeability requirements of GB/Z 33440. It was issued on 28 December 2018 and has applied since 1 July 2019.
