本標準規(guī)定了法蘭連接的鋼制壓力釋放閥門的術(shù)語和定義、訂貨指南、技術(shù)要求、性能要求、試驗方法和檢驗規(guī)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(yè)用法蘭連接鋼制彈簧直接載荷式壓力釋放閥和先導(dǎo)式壓力釋放閥。
GB/T 24921的本部分規(guī)定了石化工業(yè)用的氣體、蒸汽、不可壓縮性流體和兩相流介質(zhì)的壓力釋放閥的術(shù)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(yè)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(guī)定了石化工業(yè)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(yè)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(yè)設(shè)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(zhuǎn)壓縮機規(guī)定了術(shù)語和定義、基本設(shè)計、輔助設(shè)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(huán)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.
