コンプライアンス概要
この概要は現在英語のみで提供しています。
適用範囲
This standard specifies the quality requirements, testing methods, and inspection rules for commercial natural gas. It applies exclusively to treated natural gas transported through pipelines. Compliance with this standard is mandatory for all natural gas entering long-distance transmission pipelines. It does not apply to untreated wellhead gas or non-pipeline transported gas.
技術要求
The standard classifies natural gas into two categories based on specific quality parameters: Class 1 and Class 2. The core technical requirements regulate the limits for gross calorific value, total sulfur, hydrogen sulfide, and carbon dioxide content. Natural gas entering long-distance pipelines must strictly meet the Class 1 quality requirements. Additionally, the standard mandates that at the custody transfer point's pressure and temperature conditions, the gas must not contain liquid water or liquid hydrocarbons. For civil gas applications, the standard references interchangeability requirements as specified in GB/Z 33440.
試験方法
GB 17820-2018 outlines specific testing methodologies by referencing various national standards. The determination of sulfur compounds, including total sulfur and hydrogen sulfide, is conducted using methods from the GB/T 11060 series. The calculation of gross calorific value relies on compositional analysis performed according to GB/T 13610 or GB/T 27894. For arbitration purposes, specific primary testing methods are designated for each parameter. Sampling procedures must follow GB/T 13609 or GB/T 30490 at the agreed custody transfer point.
よくある質問
What products are regulated under GB 17820-2018?
This standard regulates treated commercial natural gas that is transported through pipelines. It is mandatory for gas entering long-distance transmission pipelines.
Is GB 17820-2018 a mandatory standard?
