管道专业术语常用英语单词

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ayout；design毛重grossweight施工图final净重netweight平面图plan支座saddle立面图elevation支架support轴测图、透视图isometricdrawing；detaildrawing吊架cradle详图、大样图、接点图recorddrawing间距distance；clearance；spacing修改图竣工图as-completeddrawing；as-builtdrawing跨距span图名title焊接welding图号drawnNo.焊缝weld；weldingseam；bead比例scale石棉水泥接口asbestos-cementjoint温度temperature青铅接口leadjoint设计温度designtemperature承口、大头hub；bell；socket湿度humidity插口、小头spigot流量flow压力试验pressuretest流速flowvelocity水压试验hydraulictest摄氏温度centigradescale(℃)渗漏leakage华氏温度Fahrenheitscale(°F)关闭close公称直径nominaldiameter(DN)型号、类型type；model外径outsidediameter(OD)尺寸、体积size；volume内径insidediameter(ID)功率power一览表list；breviate；catalogue转速rotatingspeed重量weight二、材料设备镀锌钢管galvanizedsteelpipe溢流管overflowpipe焊接钢管weldedsteelpipe循环管circulationpipe无缝钢管seamlesssteelpipe放水管ajutage不锈钢管stainlesssteelpipe煤气管gaspipe铸铁给水管castironpipeforwater压缩空气管compressedairpipe铸铁排水管castironpipeforwaste液化石油气管LPGpipe铜管copperpipe氧气管O2pipe聚氯乙烯塑料管PVCpipe乙炔管C2H2pipe硬聚氯乙烯塑料管UPVCpipe真空管vacuumpipe陶土管、缸瓦管vitrifiedpipe地下管道undergroundpipe预应力混凝土管prestressedconcretepipe顶管jacking螺纹连接管道screwedpipe；threadpipe埋深placingdepth套管、保护管casingpipe；casingprotectedpipe管沟trench管道附件pipeauxiliaries管道工plumber阀门valve安装install；erect；fit；fix手动阀manuallyoperatedvalve安装工程installation气动阀pneumaticallyoperatedvalve组装make-up；assemble电磁阀electromagneticallyoperatedvalve热水采暖hotwaterheating电动阀electricallyoperatedvalve蒸汽采暖steamheating闸阀gatevalve自动消防系统automaticfiresystem截止阀breakvalve喷水灭火系统sprinkersystem止回阀、单向阀checkvalve；back-pressurevalve埋设、暗敷built-in球阀globevalve；ballcock总管mainpipe减压阀pressurereducingvalve立管stack；riser疏水阀steamtrap横管horizontal安全阀safetyvalve水平管horizontal浮球阀floatvalve支管branchpipe角阀anglevalve向上去toabove(T/A)蝶阀butterflyvalve向下去tobelow(T/B)底阀、吸水阀footvalve坐标coordinates过滤器strainer；filter绝对标高absoluteelevation；absolutelevel水嘴、龙头tap相对标高relativeelevation；relativelevel冲洗阀flushvalve坡度slope旁通阀by-passvalve找中心centring旋塞cock；plugcock安装误差installationdeviation管件pipefitting绝对压力absolutepressure马铁配件mitisironfittings相对压力relativepressure弯头elbow设计压力designpressure三通Tee操作压力operatingpressure四通cross盲板、法兰盖blind补芯、内外丝bushing垫片gasket管接头coupler；socket螺栓bolt活接头、由任union螺母nut异径管、大小头reducer盘根、密封填料packing短接头、对丝nipple软管接头connection锁母、纳子nutU形螺丝、U形轧头stirrup管堵、塞头plug洗脸盆、面盆washbasin；lavatory套筒、套袖sleeve大便器、马桶closet；watercloset；lavatorybowl弯管bend浴缸bathtub乙字管offset小便斗urinalU形弯closereturnbend莲蓬头、淋浴器shower；showernozzle法兰flange地漏floordrain设计design存水弯siphontrap；trap；runningtrap校对check卫生设备plumbingfixture；sanitaryfitting专业负责人chief水泵pump设计总负责人projectchief水塔watertower投标tender；bid水表discmeter；ratingmeter概算budgetestimate离心泵centrifugalpump预算(表)budget消火栓、消防龙头firehydrant；fireplug决算actualbudget室内消火栓indoorfirehydrant规范、标准、准则code；standard室外消火栓outdoorfirehydrant底层groundfloor(英)；firstfloor(美)地上消火栓postfirehydrant二层firstfloor(英)；secondfloor(美)地下消火栓flushfirehydrant三层secondfloor(英)；thirdfloor(美)消防箱firebox锅炉房boilerroom泡沫灭火器foamfireextinguisher泵房pumproom卤代烷灭火器halonfireextinguisher楼上upstairs二氧化碳灭火器CO2fireextinguisher楼下downstairs干粉灭火器powderfireextinguisher夹层mezzanine清水灭火器plainwaterfireextinguisher地下室basement；cellar消防器材fiveapparatus；fire-fightextinguisher顶层groof；ceiling；topfloor报警器warning卧室、起居室bedroom；livingroom水箱tank盥洗间lavatory锅炉boiler厕所toilet补偿器、膨胀节compensator；expander浴室bathroom散热器(片)radiator厨房kitchen加热器heater技术要求specification热交换器heatexchanger外观检查visualinspection人孔manhole；hatch验收、认可accept；acceptance空调器airconditioner现场site；jobsite,workingsite煤气表gasmeter工期completionperiod煤气灶gascooker扫地出门jobcleanup绝缘跨接导线bridlewire竣工complete冷凝器condenser进水管inletpipe油分离器oilseparator出水管outletpipe防锈漆rustprotectionpaint上水管waterpipe；feedwater；watersupply保温层insulation；insulator下水管drainpipe；wastepipe压力表pressuregauge废水管wastepipe温度计temperaturegauge；thermometer粪便污水管soilpipe,sewerpipe液位计levelgauge；levelindicator透气管ventpipe下水窨井drainwell雨水管stormdrainpipe；stormsewer污水窨井sewerman-hole冷水管coldwaterpipe化粪池septictank；anaerobictank热水管hotwaterpipe阀门井valvewell蒸气管steampipe冷冻水管freezingwaterpipe冷凝水管condensatepipe回水管returnwaterpipe冷却水管coolingwaterpipe
