Lapho izinga lokushisa lokusebenza le-carbon steel lingaphansi kuka -2 ℃, futhi lapho izinga lokushisa le-carbon steel lingaphansi kuka-0 ℃, akufanelekile ukusebenzisa imishini yokubhoboza nokugunda. Amapuleti ensimbi aminyene adala imifantu ngemva kokusikwa kocingo kufanele aphathwe ngokushisa ngokushesha ngemva kokushisela, ngaphandle kwalokho ukwelashwa kokushisa kufanele kwenziwe. Ukwelashwa kokushisa kwe-weld post of flanged rubber expansion joint kuyokwenziwa ngokuhambisana nezidingo ze-DL/T752, kodwa ekwelashweni okukhulu kokushisa kwe-weld, izinga lokushisa lokulawula izinga lokushisa lizoba ngu-2 ℃ ~ 3 ℃ ngaphansi kunaphakathi nendawo futhi liphansi. izinga lokushisa lezinto zokuqala nhlangothi zombili kanye ne-welding deposition.
Ijoyinti yokwandisa irabha yohlobo lwe-Flange izofakwa ngokulandela izinyathelo ezilandelayo:
1. Ukulungiselela: Hlanza i-flange nezindawo zokuvala kuzo zombili izinhlangothi zepayipi, futhi uhlole ukuthi ama-flange, amabhawodi, nama-gaskets aphelele futhi akonakele.
2. Ukufakwa kwe-Flange: qondanisa i-flange yejoyinti lokunweba lenjoloba ne-flange ezinhlangothini zombili zepayipi, dlulisa ibhawodi phakathii-flangeemgodini, bese usebenzisa okokugcoba okufanele kunati le-flange.
3. Lungisa i-joint yokwandisa: ngemva kokulungisa i-flange, lungisa isiqondiso kanye nesimo sejoyinti yokwandisa irabha ukuze uyigcine esimweni semvelo futhi ugweme ukucindezeleka ngokweqile noma ukucindezela.
4. Intambo okusetshenzwa kulengwa kuyo engaguquki: Uma kudingeka i-flange yehange, induku yesikhonkwane idinga ukuxhunywa kwi-flange futhi ifakwe ihange phansi noma ubakaki ngokusebenzisa izinto ezingashintshiwe njengezingcwecwe zehange.
5. Ama-bolts aqinile: qinisa ama-bolts ngokushintshana kusuka kuzo zombili iziphetho kuze kube yilapho wonke ama-bolts eqiniswa ngokulinganayo nangokulinganisela ukuze kuqinisekiswe ukuvala nokuxhuma ukusebenza phakathi kwe-flange nokuhlanganiswa kwenjoloba yokwandisa.
6. Ukuhlola: ekugcineni, hlola ukuthi yonke inqubo yokufaka iyahlangabezana yini nezidingo, futhi uqinisekise ukuthi iukunweba ukujoyinaifakwe kahle
Impahla nokufakwa kwejoyinti lokunwetshwa kwenjoloba ene-flanged kukhombisa ukuchezuka okuthile, ngakho-ke ingalungiswa ngokuya ngemininingwane yangempela yokufaka phakathi nokufakwa nokulungiswa, futhi amandla okushayela nge-radial angadluliselwa kuwo wonke ama-software wesistimu yamapayipi ngesikhathi sokusebenza. Lokhu akugcini nje ngokuthuthukisa ukusebenza kahle komsebenzi, kodwa futhi kunomphumela othile wokuvikela emishinini yemishini yamapayipi njengamaphampu nama-valve.
Imiyalo yokufaka yeinhlanganisela yenjoloba ye-flange. Lapho izinga lokushisa lishintsha, ipayipi linganwetshwa ngokukhululekile futhi linciphe phakathi nendawo esibonakalayo. Lapho isisekelo sicwila, ipayipi lingatsheka futhi liqinisekise ukuthi akukho ukuvuza ekuvaleni, bese libe nenjongo yesinxephezelo esizenzakalelayo.
Ijoyinti lenjoloba elinomkhawulo we-flange elilodwa lifanele ukuxhunywa nge-flange kanye nokushisela ngepayipi. Ngesikhathi sokufakwa, lungisa ubude benhlangano phakathi kwezinhlangothi ezimbili zempahla kanye nepayipi noma i-flange, qinisa amabhawodi okusetshenzwa kulengwa ekhava yevalvu ngokulinganayo e-engeli ephezulu, bese ulungisa amantongomane ukuze ipayipi likwazi ukwanda futhi linciphe ngokukhululekile ngaphakathi kwe-engeli ephezulu. ububanzi bokuhoxisa nokuhlehla, ukukhiya inani lokunwetshwa nokufinyezwa, futhi ipayipi lingasebenza ngokwethembeka. Ijoyinti lokunwetshwa kwenjoloba elikhawulela i-Flange lifanele ukuxhuma izinhlangothi zombili ze-flange. Ngesikhathi sokufakwa, lungisa ubude bokuxhumana bezinhlangothi zombili zempahla, qinisa amabhawudo ebhonethi ngokulinganayo engeli eliphezulu, bese ulungisa nati lokuma, ukuze ipayipi linwetshwe futhi linwetshwe ngokuthanda kwakho, nobude bazo zombili iziphetho. idivayisi yokwandisa ingalungiswa. Ijoyinti lokunwetshwa kwenjoloba lifanele ukuxhuma izinhlangothi zombili ngepayipi ngaphandle kokushisela ugesi, elinesakhiwo esinengqondo, ukusebenza kahle kokuvala, nokufakwa okusheshayo nokulula.
Ijoyinti yokunwetshwa kwerabha enomkhawulo owodwa we-flange inomphumela othile we-offset ezinhlangothini eziningi ekusebenzeni kwepayipi, futhi idlala indima ebalulekile esinxephezelweni sokunwetshwa kokudangala okungaphezulu kanye nesikhathi sokugoba ngenxa yokwanda okushisayo emsebenzini wepayipi. Ngakho-ke, ijoyinti yokwandisa irabha inganciphisa amandla okucindezelaipuleti eliyimpumputheekusebenzeni kwepayipi, futhi inokugcinwa okuthile kwepayipi, ikakhulukazi ukufakwa nokugcinwa kwepayipi. Ijoyinti elilodwa le-flange elikhawulela irabha lokunwetshwa lizohlonywa okokusebenza kokumisa ngesisekelo sezici zangempela zejoyinti lokunweba lerabha, futhi lizokhiywa ngamantongomane endaweni ngenani elikhulu lokunwetshwa. Ipayipi linganwetshwa ngaphandle kwesizathu phakathi kwebanga lokunwetshwa elivunyelwe, futhi uma selidlule isandiso salo esikhulu, lingaqinisekisa ukusebenza okuthembekile kwepayipi, ikakhulukazi kumapayipi anokudlidliza noma ukuthambekela okuthile nama-engeli aphendukayo.
