Bevel qhov kawg ntawm cov yeeb nkab thiab mating nto ntawm lub caj dab flange kom yooj yim rau txoj kev vuam. Lub kaum sab xis thiab kev npaj ntawm qhov chaw yuav tsum ua raws li cov kev qhia tshwj xeeb thiab cov qauv kom ntseeg tau tias muaj zog thiab txhim khu kev qha weld sib koom ua ke.
Tack vuam
Siv tack welds kom ruaj khov ib ntus ntawm flange rau cov yeeb nkab hauv qhov xav tau. Tack welds pab kom muaj kev sib haum xeeb thiab tiv thaiv kev txav mus los thaum lub sijhawm vuam kawg.
Vuam
Ua qhov kawg welding mus tas li txuas lub flange rau cov yeeb nkab. Siv cov txheej txheem vuam xws li shielded hlau arc vuam (SMAW), roj tungsten arc vuam (GTAW), lossis roj hlau arc vuam (GMAW), nyob ntawm cov khoom thiab thickness ntawm flange thiab yeeb nkab.
Kev tshuaj xyuas tom qab vuam
Tom qab vuam, tshuaj xyuas qhov sib koom ua ke rau qhov tsis xws li cov kab nrib pleb, porosity, lossis kev nkag tsis tiav. Siv cov kev sim uas tsis yog kev puas tsuaj (NDT) xws li kev tshuaj xyuas qhov muag, kev tshuaj ntsuam xyuas qhov muag, lossis kev kuaj hluav taws xob los xyuas kom meej qhov zoo ntawm cov vuam.
Ntxuav thiab ua kom tiav
Tshem tawm cov welding slag, spatter, lossis lwm yam khoom seem ntawm qhov sib koom ua ke thiab ib puag ncig siv txoj kev tu kom tsim nyog. Smooth tej npoo npoo los yog imperfections kom huv si thiab flush nto.
Kev sim
Ua kev ntsuam xyuas siab los yog kev ntsuam xyuas ntawm cov kav dej los xyuas qhov tseeb thiab kev ua tau zoo ntawm qhov sib koom ua ke. Pressurize lub kaw lus maj mam thiab saib xyuas rau tej yam tshwm sim ntawm to lossis siab poob.
Kev tshuaj xyuas zaum kawg thiab kev pom zoo
Thaum lub installation tiav thiab qhov sib koom ua ke tau dhau los ntawm kev tshuaj xyuas thiab kev sim, tau txais kev pom zoo los ntawm cov tub ceev xwm lossis cov neeg muaj feem cuam tshuam ua ntej muab cov kav dej tso rau hauv kev pabcuam.
Dab tsi yog Cov Txheej Txheem Kev Ntsuas Feem ntau siv los xyuas kom meej qhov kev ncaj ncees ntawm Neck Flat Vuam Flanges
Muaj ntau txoj hauv kev sim siv los xyuas kom meej qhov kev ncaj ncees ntawm caj dab ca vuam flanges thiab qhov zoo ntawm cov pob qij txha. Cov txheej txheem no pab txheeb xyuas qhov teeb meem lossis qhov tsis zoo uas tuaj yeem cuam tshuam kev ua haujlwm lossis kev ntseeg siab ntawm flanges.
Kev kuaj pom pom yog qhov yooj yim tshaj plaws thiab feem ntau siv txoj hauv kev los ntsuas qhov zoo ntawm cov pob qij txha. Cov kws tshuaj ntsuam xyuas tau pom pom qhov chaw vuam rau qhov tsis sib xws, xws li tawg, porosity, tsis tiav fusion, los yog undercutting. Txoj kev no yuav tsum tau txais kev cob qhia cov neeg ua haujlwm thiab cov teeb pom kev zoo txaus rau kev kuaj xyuas kom raug.
Liquid penetrant testing yog ib qho kev sim uas tsis muaj kev puas tsuaj uas siv los txheeb xyuas qhov tsis xws luag hauv cov welds. Ib tug kua penetrant yog siv rau saum npoo ntawm lub weld, thiab tom qab ib tug teev nyob rau hauv lub sij hawm, ntau penetrant raug tshem tawm. Tom qab ntawd tus tsim tawm yog siv, uas rub lub penetrant tawm ntawm tej yam tsis xws luag, ua rau lawv pom nyob rau hauv ultraviolet los yog lub teeb dawb. Txoj kev no yog rhiab rau me me defects thiab feem ntau yog siv rau ferrous thiab non-ferrous cov ntaub ntawv.
Magnetic particle testing yog lwm txoj kev kuaj uas tsis muaj kev puas tsuaj uas siv los txheeb xyuas qhov chaw thiab qhov ze ntawm qhov chaw nyob hauv cov ntaub ntawv ferromagnetic. Ib qho chaw sib nqus yog siv rau thaj tsam weld, thiab cov khoom sib nqus tau siv rau saum npoo. Txhua qhov chaw tsis xws luag, xws li cov kab nrib pleb lossis laps, cuam tshuam cov hlau nplaum, ua rau cov khoom sib nqus ntawm qhov chaw tsis raug, ua rau cov neeg soj ntsuam pom. Txoj kev no muaj txiaj ntsig zoo rau kev kuaj xyuas qhov tsis xws luag hauv welds thiab thaj chaw muaj kev kub ntxhov.
Kev ntsuam xyuas hluav taws xob siv X-rays lossis gamma rays los tsim cov duab ntawm cov qauv sab hauv ntawm welds. Txoj kev no tuaj yeem txheeb xyuas cov teeb meem sab hauv xws li tsis muaj fusion, porosity, slag inclusions, thiab tawg. Kev ntsuam xyuas hluav taws xob feem ntau yog siv rau cov ntaub ntawv tuab lossis thaum nkag mus rau ob sab ntawm qhov sib txuas yog txwv. Nws xav tau cov cuab yeej tshwj xeeb thiab cov kws tshaj lij xov tooj cua los txhais cov duab hluav taws xob kom raug.
Ultrasonic kuaj siv lub suab tsis muaj suab nrov los kuaj xyuas qhov tsis xws luag sab hauv thiab saum npoo hauv welds. Lub transducer yog siv los xa cov nthwv dej ultrasonic los ntawm cov khoom siv, thiab txhua qhov tsis sib xws hauv cov vuam, xws li cov kab nrib pleb lossis tsis muaj fusion, muaj kev cuam tshuam cov suab nthwv dej, uas kuaj pom los ntawm cov transducer. Kev kuaj ultrasonic yog ntau yam thiab tuaj yeem siv rau ntau yam khoom thiab thicknesses. Nws yog feem ntau siv rau kev soj ntsuam vuam hauv cov ntawv thov tseem ceeb.
Kev ntsuas siab muaj xws li nias lub kav dej los yog sib koom ua ke nrog cov kua dej (xws li dej los yog cua) mus rau qhov ntsuas siab thiab saib xyuas cov cim qhia txog kev xau lossis kev poob siab. Txoj kev no yog siv los txheeb xyuas qhov kev ncaj ncees thiab xau-nruj ntawm cov pob qij txha thiab cov kav dej hauv kev ua haujlwm. Kev ntsuas siab tuaj yeem ua tau hydrostatically (nrog dej) lossis pneumatically (nrog huab cua lossis roj), nyob ntawm cov ntawv thov.
