本標準規定了法蘭連接的鋼制壓力釋放閥門的術語和定義、訂貨指南、技術要求、性能要求、試驗方法和檢驗規則、標志銘牌和包裝貯運。本標準適用于公稱壓力PN20~PN420,公稱尺寸DN25~DN200,整定壓力不小于0.1MPa的石化工業用法蘭連接鋼制彈簧直接載荷式壓力釋放閥和先導式壓力釋放閥。
GB/T 24921的本部分規定了石化工業用的氣體、蒸汽、不可壓縮性流體和兩相流介質的壓力釋放閥的術語和定義、類型特征和尺寸的確定等。本部分適用于石化工業用整定壓力不小于0.1 MPa的壓力釋放閥。
GB/T 24921的本部分規定了石化工業用壓力釋放閥的安裝一般要求、進口和排放管道、隔離閥安裝、通氣孔的安裝、不同整定壓力的多閥安裝、安裝前檢查。本部分適用于石化工業用整定壓力不小于0.1 MPa的壓力釋放閥。
本標準對在石油、石化和天然氣工業設施中,用于抽取真空或提高壓力或兩者都有的干螺桿和噴油螺桿回轉壓縮機規定了術語和定義、基本設計、輔助設備、檢驗、試驗和裝運準備及賣方資料等要求。是用作專門用途的工藝流程壓縮機。本標準不適用于一般的空氣壓縮機、液環式壓縮機和葉片式壓縮機。
This International Standard provides procedures for the laboratory testing of both drilling fluid materials and drilling fluid physical, chemical and performance properties. It is applicable to both water-based and oil-based drilling fluids, as well as the base or “make-up” fluid.

This International Standard provides procedures for the laboratory testing of both drilling fluid materials anddrilling fluid physical, chemical and performance properties. It is applicable to both water-based and oil-baseddrilling fluids, as well as the base or “make-up” fluid.It is not applicable as a detailed manual on drilling fluid control procedures. Recommendations regardingagitation and testing temperature are presented because the agitation history and temperature have aprofound effect on drilling fluid properties.
