Ukubambezeleka okuningi kokusebenza akuveli ekugijimeni kwamapayipi aqondile. Avela ezindaweni zokuhlangana-ezinzima{2}}ukulungisa, ukulungiswa kwe-weld okuphindaphindiwe, ukungahambi kahle kwebholithi{3}}imbobo, ukuvuza kwe-hydrotest, kanye namadokhumenti okwamukela angangeni. Ukuxhumana okuthembekile kwepayipi nomphumela wokuvala kuncike ezintweni ezimbili eziyisisekelo: ijometri ehlanganyelwe elawulekayo kanye nomthwalo wokuvala ophindaphindwayo.
Izindlela Zokuxhuma kanye Nezilawuli Ezibalulekile
1. Izixhumanisi zokushisela{1}}yini ngempela eqhuba uzinzo?
Ijoyinti elishiselwe ezinzile livela ekusebenzisaneni ekulungiseni ekugcineni,{0}}ukulingana, ukwenziwa kokushisela, nokuhlola. Emkhakheni, ukuhlukahluka kwejiyomethri kanye nokwehluka kokushisa{2}}yikhona okuthuthukiswayo.
- Qeda ukungaguquguquki kokulungiselela
Uma i-engeli ye-bevel, umhlaba, noma isiphetho-ikhwalithi yobuso ihluka, ukuvuleka kwezimpande kuvuleke bese iwindi lokushisela libe lincane. Uphawu oluvamile izinga lokuphasa elingahambisani emgqeni ofanayo.
- Ukulawula{0}}ukulinganisa nokuqondanisa
Ukuvuleka kwezimpande, ukungafani kwangaphakathi, kanye ne-ovality/concentricity kuthinta ngokuqondile ukuhlanganiswa kwezimpande kanye nemiphumela ye-NDE. Izindonga-ezincane, i-OD encane, kanye{2}}neziqephu ezimfishane zizwela kakhulu.
- Iwindi lokufaka{0}lokushisa{0}lokufaniswa nokokusebenza nokuqina
Okuphansi kakhulu kwandisa ukuntuleka kwengozi yokuhlanganisa/yokungena; ukuphakama kakhulu kukhulisa ukuhlanekezela futhi kungathinta{0}}isimo sobuso.
- Ukuhlola nokulungisa ukufinyeleleka
Uma amalunga egcwele eduze kwezisekelo, izindonga, amavalvu, noma izinto zokusebenza, i-NDE kanye nokufinyelela kokulungisa kuvame ukuba umshayeli wangempela wobungozi beshejuli.
Uma uxhumano olushiselwe luboshelwe ku-flange, ukuhlanekezela kwe-welding kungasusa inkinga isuke enkingeni yekhwalithi ye-weld ibe inkinga yokuvala{1}}ukuvuza kwendawo okubangelwa ukuminyaniswa kwe-gasket okungalingani.
2. I-Socket/fillet welding-kungani imithetho yokuhlanganisa ibaluleke ngaphezu kokubukeka
Amajoyinti esitayela-esokhethi ngokuvamile abukeka emahle ngokubukeka, kodwa ukuzinza kuncike kakhulu ekusebenzeni okuphindaphindwayo kokuhlanganisa.
- Ukujula kokufakwa okungaguquki kanye negebe lehlombe
- I-fillet weld geometry ephindaphindwayo, ikakhulukazi ezindaweni zokufinyelela eziqinile
- Ukuzwela okuphezulu ekukhathaleni ngaphansi kwesevisi yebhayisikili nokudlidliza
- I-Crevice{0}}ukuhlanzeka kwendawo kanye nokuziphatha kokugqwala okuhambisana nendawo yesevisi
3. Ukuxhumana okunemicu{1}}ukwethembeka kuyisiyalo sokuhlanganisa
Amajoyinti anemicu azinzile kuphela njengendinganiso yokuhlanganisa ngemuva kwawo.
- Ifomu lentambo elilungile kanye nokuzibandakanya okwanele
- Ukulawulwa kokulimala ezindaweni zochungechunge
- Uhlobo lwe-sealant olungaguquki kanye nendlela yokufaka isicelo
- Ukuqinisa okuchaziwe futhi{0}}uhlole futhi ukuzijwayeza
- Sula ukucabanga{0}}okukhululayo ngaphansi kokudlidliza nokuhamba ngebhayisikili okushisayo
Yini elawula ukusebenza kokubekwa uphawu kwe-Flange?
Amalungu e-Flange ahumusha ikhwalithi yokuhlanganisa ngokuqondile emiphumeleni yokuvala. Ukubekwa uphawu okuzinzile kudinga izinto ezintathu okufanele zilawulwe ndawonye: isimo sobuso be-flange, iwindi elisebenza nge-gasket, kanye nokulayishwa kuqala kwebhawodi okuphindaphindwayo.
1. Isimo sobuso be-flange
- Ukucaba/ukuphaphatheka kushayela ukufana kokuminyanisa
- Ukuqedwa kobuso kuthinta ukulunywa kwe-gasket nokululama
- Ama-nick, amazinyo, nokugqwala kuba yizindlela zokuvuza
- Ukuhlanekezela kwe-welding kungadala ukucindezelwa kwendawo ngaphezulu/ngaphansi-
Uphawu lwenkambu olujwayelekile ukuvuza okugxiliswe ohlangothini olulodwa noma eduze kwamabhawudi ambalwa, hhayi ngisho nokushona eduze kwesiyingi esigcwele.
2. Iwindi elisebenza nge-gasket
- Ngaphansi-ukucindezela kubangela ukuvuza kwangaphambi kwesikhathi
- Ukucindezela{0}ngaphezulu{0}kuchoboza i-gasket futhi kunciphisa ukululama, kuvame ukuba kubi kakhulu ngemva kwemijikelezo yokushisa
- Izinga lokushisa nemidiya kusheshisa ukukhasa/ukuphumula, kunciphisa ingcindezi ye-gasket esebenzayo ngokuhamba kwesikhathi
Ukuthuthukisa i-gasket kukodwa kunenani elilinganiselwe uma isimo sobuso noma ukungaguquguquki kokulayisha kuqala kuyisibopho sangempela.
3. Ukuvumelana kokulayisha kuqala kwebhowudi
- Ukulandelana kokuqinisa okuhlukile kudala ingcindezi ye-gasket engalingani
- Ukuqinisa{0}ngaphezulu kungasonta ubuso futhi kunciphise ukuzinza kokuvala
- Ukugcotshwa nokuhlukahlukana kwe-friction kwenza i-torque-ukuba{1}}ilayishe kuqala ingahambisani
- Imijikelezo yokushisa nokudlidliza kunciphisa ukulayisha kuqala, ngokuvamile okuholela-ekuvuzeni kwempilo kwangaphambi kwesikhathi

I-oda elisebenzayo-lokuqinisekisa isayithi lama-Flange Joints
Isinyathelo 1: Hlola ubuso be-flange kuqala
- Umonakalo obonakalayo: ama-nicks, imihuzuko, izifaca, izindawo zokugqwala
- Izimpawu zokuxhumana okungalingani noma ukuhlanekezela, ikakhulukazi ngemva kokushisela
- Amaphethini endawo avuzayo ahambisana nezinkinga zobuso bendawo
Isinyathelo sesi-2: Qinisekisa ukufaneleka kwe-gasket nokuziphatha kokuminyanisa
- Ifanelana nemidiya/izinga lokushisa/isimiso sokuhlanza
- I-imprint engalingani, ukuchotshozwa kwendawo, noma ukuwohloka okungavamile
- "Qinisa kakhulu kodwa kusavuza" amaphethini abonisa ukuminyanisa okungalingani noma ukulayisha kuqala okungazinzile
Isinyathelo sesi-3: Qinisekisa ukuphindaphinda kokulayisha
- Ukulandelana kokuqinisa okungaguquki nokuqinisa okufakwe esiteji
- Ukuthambisa okungaguquki nesimo sokungqubuzana
- Ukuqwashisa ngezingozi zokulahlekelwa kokulayisha kuqala ngaphansi kokuhamba ngebhayisikili okushisayo nokudlidliza
Lapho Umsebenzi Kabusha Uqala Khona
- Ukulungiselela ukuphela akuhambelani nenqubo yokushisela → i-geometry drift → ukulungiswa kuyanda
- Linganisa-ukuqondanisa phezulu/ukuqondanisa akulawuliwe → ukungafani kwangaphakathi kanye nempande engazinzile → ukwehluleka kwe-NDE
- Isitaki sokubekezelela i-spool-phezulu → ibhawodi{1}}ukungahambi kahle kwembobo → ukucindezelwa kokufaka okuphoqelelwe
- Ukuhlanekezela ukushisela kuthinta ubuso be-flange → ingcindezi engalingani ye-gasket → ukuvuza kwe-hydrotest okwenziwe kwasendaweni
- Ukuzijwayeza ukuqinisa kuyahlukahluka ngezisebenzi → ukuhlakazeka kokulayisha kuqala → ngaphambi kwesikhathi-ukuvuza kwempilo
Ukusabela okuvamile kweketango kuwukuqondanisa okuphoqelekile ukwenza izimbobo zibe umugqa → ukuminyanisa kwe-gasket okungalingani → ukuvuza phakathi nokuhlolwa → ukuqinisa okwengeziwe → ukuhlanekezela kobuso → ukuvuza okuphindelelayo.
Ikuphi ukwamukela okugxile kukho
Ukuze uthole ukuxhunywa kwamapayipi nokwamukelwa kokuvalwa, ababuyekezi ngokuvamile babheka izinto ezilandelekayo, ezilinganisekayo, neziqinisekayo:
- Ukulandeleka: ukuhlonza ukushisa/inqwaba nezitifiketi
- Isixhumi esibonakalayo-ijiyomethri ebalulekile: isimo sokuphela, ukuqondanisa, i-flange-isimo sobuso, ibhawodi{2}}ukuqondanisa kwembobo
- Ukuhlolwa okudingekayo namarekhodi okuhlola iphrojekthi ngayinye
- Iphakethe lamadokhumenti lifakwe kumephu ngokuqhubekayo kuhlu lwesixhumi esibonakalayo
Ekulethweni kwephrojekthi ye-Octal Pipe, izingxenye namadokhumenti kuvame ukuhlelwa ngokumelene nohlu olulodwa lwesixhumi esibonakalayo ukuze ingqondo yokuxhumana, indlela yokubeka uphawu, namarekhodi okwamukela ahlale ehambisana futhi kulula ukuwahlola.
