Kev tshuaj xyuas flange kom tag nrho suav nrog kev saib xyuas qhov muag pom, kev ntsuas qhov ntev, kev ntsuas tsis puas tsuaj, thiab kev lees paub cov ntaub ntawv khoom yog qhov tseem ceeb los ua kom muaj kev nyab xeeb thiab ua raws li txoj cai rau kev ua haujlwm ntawm flange. Kev puas tsuaj ntawm flange tuaj yeem ua rau muaj kev xau, hluav taws kub, kev puas tsuaj rau ib puag ncig, thiab raug mob rau tib neeg. Phau ntawv qhia no npog tag nrho cov kev xav tau ntawm kev tshuaj xyuas thiab kev ntsuas qhov zoo rau flanges.
Vim Li Cas Kev Tshuaj Xyuas Ntawd Thiaj Li Tseem Ceeb
Kev puas tsuaj ntawm flange thaum ua haujlwm tuaj yeem muaj kev cuam tshuam loj heev, suav nrog cov kua dej txheej txheem xau, hluav taws kub, tawg, ua rau ib puag ncig tsis huv, thiab raug mob rau tib neeg. Kev tshuaj xyuas yog los xyuas kom tseeb tias flanges ua raws li cov ntaub ntawv khoom, qhov ntev, thiab cov cai ua ntej lawv yuav tso rau hauv kev pab. Kev ua kom zoo ntawm kev tshuaj xyuas yog los tiv thaiv kev puas tsuaj uas raug nqi thiab kev khiav tsis tau lub tshuab uas tsis tau npaj. Kev tshuaj xyuas kom raug yog ua kom ntseeg tau tias flange yuav ua haujlwm raws li tau tsim tseg raws li nws cov kev ua haujlwm teev tseg. Rau cov kev pab uas tseem ceeb heev, kev tshuaj xyuas tsis yog qhov xaiv tau, tab sis yog txoj cai uas yuav tsum ua raws li tus qauv tsim kho thiab cov kev xav tau ntawm tus tswv txog qhov zoo.
Kev Tshuaj Xyuas Nrog Qhov Muag Pom
Kev tshuaj xyuas nrog qhov muag pom yog thawj thiab qhov tseem ceeb tshaj plaws ntawm kev ntsuas qhov zoo. Tus neeg tshuaj xyuas saib xyuas lub flange rau qhov tsis zoo saum npoo suav nrog kab tawg, kab tiaj, kab sib tshuam, thiab qhov muaj khiav dej ceev saum npoo. Cov cim ntawm lub flange raug tshuaj xyuas raws li ASME B16.5 cov kev xav tau, suav nrog lub npe lossis lub logo ntawm tus tsim, daim ntawv qhia khoom, qib siab, thiab tus naj npawb cua sov. Qhov zoo ntawm qhov chaw ntsib tau raug tshuaj xyuas rau kev khawb, kev khob, corrosion, lossis kev puas tsuaj thaum thauj khoom uas yuav cuam tshuam rau kev kaw. Kev ua kom zoo ntawm qhov tuav ntsia hlau thiab tus naj npawb raug xyuas kom meej raws li tus qauv. Xeb, scale, thiab kev qias neeg raug tshuaj xyuas ntawm txhua qhov chaw kaw.
Kev Tshuaj Xyuas Qhov Ntev
Kev tshuaj xyuas qhov ntev yog los xyuas kom tseeb tias lub flange ua tau raws li cov kev tso cai uas tau teev tseg hauv tus qauv uas siv tau. Cov kev ntsuas tseem ceeb suav nrog txoj kab uas hla sab nraud ntawm lub flange, qhov tuab tag nrho, thiab txoj kab uas hla qhov hauv. Txoj kab uas hla ntawm lub voj voog tuav ntsia hlau thiab qhov loj ntawm qhov tuav ntsia hlau yuav tsum phim cov qhov ntev ntawm tus qauv rau cov qib thiab qhov loj uas tau hais. Qhov ntev ntawm lub hub ntawm weld neck thiab reducing flanges raug tshuaj xyuas kom raug rau qhov taper thiab qhov ntev. Qhov siab ntawm lub ntsej muag siab, txoj kab uas hla, thiab qhov zoo ntawm qhov chaw raug ntsuas. Rau RTJ flanges, qhov ntev ntawm lub khawm raug tshuaj xyuas siv cov cuab yeej ntsuas tshwj xeeb. Txhua qhov ntev yuav tsum ua tau raws li ASME B16.5 cov kev tso cai.

Cov Kev Ntsuas Tsis Puas Tsuaj
Muaj ntau txoj hauv kev NDT rau kev tshuaj xyuas flange, txhua qhov muaj peev xwm tshwj xeeb. Ultrasonic Testing (UT) siv cov suab nrov nrov nrov los nrhiav cov kab ntau sab hauv, qhov muaj khiav dej ceev, thiab cov khoom sib xyaw hauv cov flanges ua los ntawm kev ntaus hlau thiab phaj. Magnetic Particle Testing (MT) nrhiav cov kab tawg saum npoo thiab ze rau saum npoo hauv cov khoom ferromagnetic siv cov hlau nplaum thiab cov khoom hlau. Liquid Penetrant Testing (PT) siv cov xim pom tau lossis xim ci los nrhiav cov kab tawg saum npoo ntawm cov khoom tsis yog hlau nplaum xws li austenitic stainless steel. Radiographic Testing (RT) siv X-rays lossis gamma rays los nrhiav cov qhov khoob sab hauv thiab cov khoom sib xyaw, feem ntau siv rau castings thiab welded fabrications. Positive Material Identification (PMI) siv X-ray fluorescence lossis optical emission spectroscopy los xyuas kom tseeb tias cov tshuaj khoom phim raws li daim ntawv qhia.
Kev Ntsuas Siab
Kev ntsuas hydrostatic pressure yog txoj hauv kev qauv los xyuas kom tseeb tias lub flange pob qhov txuas muaj zog. Lub siab ntsuas feem ntau yog 1.5 npaug ntawm qhov siab tsim, tuav rau lub sijhawm txaus los xyuas kom tseeb tias tsis muaj kev poob siab. Rau cov tshuab uas tsis tuaj yeem zam dej, kev ntsuas pneumatic nrog cua lossis inert gas yuav siv tau nrog cov kev ceev faj ntxiv. Lub siab ntsuas tau tuav thaum lub pob qhov txuas raug tshuaj xyuas rau kev xau. Rau cov tshuab kub qis lossis cryogenic, kev ntsuas hydrostatic yuav ua tau ntawm qhov kub ib puag ncig nrog lub siab ntsuas kho raws li qhov muaj zog qis ntawm cov khoom ntawm qhov kub siab dua thaum ntsuas.
Kev Tshaj Tawm Ntaub Ntawv Khoom
Cov Ntaub Ntawv Ntsuas Mill (MTRs) muab pov thawj uas sau tseg txog cov tshuaj khoom thiab cov khoom txawv ntawm cov khoom siv flange. Kev taug qab tag nrho los ntawm lub tsev hlau mus rau lub flange tiav yog khaws cia los ntawm tus naj npawb cua sov uas luam rau ntawm txhua lub flange. Cov ntaub ntawv ntsuas qhov cuam tshuam yuav tsum muaj rau cov khoom siv kub qis. Cov ntaub ntawv ntsuas hardness yuav tsum muaj qhov uas NACE MR0175 cov kev cai sour service siv tau. Rau cov kev pab tseem ceeb, cov koom haum tshuaj xyuas neeg thib peb muab kev tshuaj xyuas ywj pheej ntawm cov khoom txawv thiab qhov zoo ntawm flange.
Kev Kos Cim thiab Kev Taug Qab
ASME B16.5 yuav kom txhua lub flange raug kos cim ruaj khov nrog lub npe lossis logo ntawm tus tsim, daim ntawv qhia khoom, thiab qib siab. Cov cim ntxiv suav nrog tus naj npawb cua sov, qhov loj nominal, thiab cov cim tshwj xeeb xws li "QT" rau quenched thiab tempered. Kev kos cim yog siv los ntawm cov kev luam uas muaj kev ntxhov siab tsawg kom tsis txhob tsim cov kev ntxhov siab uas tuaj yeem pib kab tawg. Cov ntaub ntawv taug qab yog khaws cia rau tag nrho cov txheej txheem tsim, los ntawm cov hlau tshaj thawj lub hav hlau mus txog rau kev ntaus hlau, kev kho cua sov, kev tshuab, thiab kev tshuaj xyuas kawg.
