管道专业术语常用英语单词在引进装置、涉外及中外合资技术改造工程的技术资料中，经常要接触到英语单词。由于管道安装涉及多项工程技术，而不从属于任何一项工程技术分支，故其技术性质有一定特殊性，不少英语词汇是在实践中逐渐形成的，借助一般科技英汉词典有时也难以找到它们的确切含意。现将管道安装工程中出现较多的单词整理列出，如果能熟悉这些单词，对阅英文图纸能收到事半功倍的效果。一、专业名词术语设计图施工图平面图立面图轴测图、透视图详图、大样图、接点图修改图竣工图图名图号比例温度设计温度湿度流量流速摄氏温度华氏温度ayout；designfinalplanelevationisometricdrawing；detaildrawingrecorddrawingas-completeddrawing；as-builtdrawingtitledrawnNo.scaletemperaturedesigntemperaturehumidityflowflowvelocitycentigradescale(℃)Fahrenheitscale(°F)??毛重净重支座支架吊架间距跨距焊接焊缝石棉水泥接口青铅接口承口、大头插口、小头压力试验水压试验渗漏关闭grossweightnetweightsaddlesupportcradledistance；clearance；spacingspanweldingweld；weldingseam；beadasbestos-cementjointleadjointhub；bell；socketspigotpressuretesthydraulictestleakageclose公称直径外径内径一览表?nominaldiameter(DN)outsidediameter(OD)insidediameter(ID)list；breviate；catalogue?型号、类型尺寸、体积功率转速重量type；modelsize；volumepowerrotatingspeedweight二、材料设备镀锌钢管焊接钢管无缝钢管不锈钢管铸铁给水管铸铁排水管铜管聚氯乙烯塑料管硬聚氯乙烯塑料管陶土管、缸瓦管预应力混凝土管螺纹连接管道套管、保护管管道附件阀门手动阀气动阀电磁阀电动阀闸阀截止阀止回阀、单向阀球阀galvanizedsteelpipeweldedsteelpipeseamlesssteelpipestainlesssteelpipecastironpipeforwatercastironpipeforwastecopperpipePVCpipeUPVCpipevitrifiedpipeprestressedconcretepipescrewedpipe；threadpipecasingpipe；casingprotectedpipepipeauxiliariesvalvemanuallyoperatedvalvepneumaticallyoperatedvalveelectromagneticallyoperatedvalveelectricallyoperatedvalvegatevalvebreakvalvecheckvalve；back-pressurevalveglobevalve；ballcock??溢流管循环管放水管煤气管压缩空气管液化石油气管氧气管乙炔管真空管地下管道顶管埋深管沟管道工安装安装工程组装热水采暖蒸汽采暖自动消防系统喷水灭火系统埋设、暗敷总管overflowpipecirculationpipeajutagegaspipecompressedairpipeLPGpipeO2pipeC2H2pipevacuumpipeundergroundpipejackingplacingdepthtrenchplumberinstall；erect；fit；fixinstallationmake-up；assemblehotwaterheatingsteamheatingautomaticfiresystemsprinkersystembuilt-inmainpipe减压阀疏水阀安全阀浮球阀角阀蝶阀底阀、吸水阀过滤器水嘴、龙头冲洗阀旁通阀旋塞管件马铁配件弯头三通四通补芯、内外丝管接头活接头、由任异径管、大小头短接头、对丝锁母、纳子pressurereducingvalvesteamtrapsafetyvalvefloatvalveanglevalvebutterflyvalvefootvalvestrainer；filtertapflushvalveby-passvalvecock；plugcockpipefittingmitisironfittingselbowTeecrossbushingcoupler；socketunionreducernipplenut立管横管水平管支管向上去向下去坐标绝对标高相对标高坡度找中心安装误差绝对压力相对压力设计压力操作压力盲板、法兰盖垫片螺栓螺母盘根、密封填料软管接头U形螺丝、U形轧头stack；riserhorizontalhorizontalbranchpipetoabove(T/A)tobelow(T/B)coordinatesabsoluteelevation；absolutelevelrelativeelevation；relativelevelslopecentringinstallationdeviationabsolutepressurerelativepressuredesignpressureoperatingpressureblindgasketboltnutpackingconnectionstirrup管堵、塞头套筒、套袖弯管乙字管U形弯法兰设计校对专业负责人设计总负责人投标概算预算(表)决算规范、标准、准则底层二层三层锅炉房泵房楼上楼下夹层plugsleevebendoffsetclosereturnbendflangedesigncheckchiefprojectchieftender；bidbudgetestimatebudgetac...
