Iiflange zizinto ezibalulekileyo kwiinkqubo zemibhobho, ukusebenza njengendlela yokudibanisa imibhobho, iivalve, kunye nezinye izixhobo. Zenzelwe ukubonelela ngoqhagamshelwano olukhuselekileyo kunye nobungqina bokuvuza, ukuqinisekisa imfezeko yenkqubo. Iiflange ziza ngokwemilo kunye nobukhulu obahlukeneyo, ngezona ntlobo zixhaphakileyo yiweld neck, ukutyibilika, socket weld, kunye neeflange ezinemisonto. Uhlobo ngalunye luneempawu zalo ezizodwa kunye nezicelo, ukwenza ukuba kubaluleke ukukhetha uhlobo olululo lweflange lwenkqubo ethile yemibhobho.
Iiflange zenziwe ngezinto ezinje ngentsimbi yekhabhoni, yenziwe ngentsimbi eshayinayo, kunye nentsimbi ye-alloy, ngemathiriyeli nganye enika amanqanaba ahlukeneyo amandla kunye nokumelana nomhlwa. Ukukhethwa kwezinto zeflange kubalulekile ekuqinisekiseni ixesha elide kunye nokusebenza kwenkqubo yemibhobho.. Ukuqonda iintlobo ezahlukeneyo zeeflange kunye nezinto zazo ziyimfuneko ekufakeni ngempumelelo kunye nokugcinwa kweenkqubo zombhobho.
Izixhobo kunye nezixhobo ezifunekayo kuFakelo lweFlange
Ngaphambi kokuqala ukufakwa kweflange, kubalulekile ukuqokelela zonke izixhobo eziyimfuneko kunye nezixhobo. Izixhobo ezifunekayo ukufakela i-flange ziquka i-torque wrench, isitshixo sombhobho, inqanaba, iteyiphu yokulinganisa, kunye nesethi yezitshixo. Ukongeza, kubalulekile ukuba nezixhobo ezifanelekileyo zokhuseleko ezifana neeglavu, iiglasi zokhuseleko, kunye nokukhuselwa kweendlebe ukuqinisekisa ukhuseleko lomfakeli.
Ngokumalunga nezixhobo, awona macandelo abalulekileyo ofakelo lweflange ziiflange ngokwazo, kunye neegaskets, iibholiti, kunye namandongomane. Igasket licandelo elibalulekileyo elibonelela ngokutywina phakathi kobuso beflange, ukuthintela ukuvuza kwimibhobho. Kubalulekile ukukhetha uhlobo oluchanekileyo lwe-gasket esekelwe kwiimeko zokusebenza kunye nokuhanjiswa kwamanzi ngenkqubo yokubhobhoza. Iibholiti kunye namantongomane zisetyenziselwa ukukhusela iiflange kunye, kwaye kubalulekile ukukhetha ibakala elifanelekileyo kunye nobukhulu beebholiti kunye namantongomane ngokusekwe kuxinzelelo kunye neemfuno zobushushu benkqubo yemibhobho..
Ukulungiselela iFlange kunye nePipe yokuFakela
Ngaphambi kokufaka i-flange, kubalulekile ukulungiselela zombini i-flange kunye nombhobho ukuqinisekisa uxhulumaniso olufanelekileyo nolukhuselekileyo. Isinyathelo sokuqala ekulungiseleleni i-flange kukuyihlola naziphi na iziphene okanye umonakalo. Nakuphi na ukungafezeki kwi-flange surface kunokukhokelela ekuvuzeni okanye ukungaphumeleli kwindlela yokubhobhoza, ngoko ke kubalulekile ukuhlolisisa ngenyameko i-flange ngaphambi kokufakwa.
Emva kokuba i-flange ihlolwe kwaye ibonwa ifanelekile ukufakwa, isinyathelo esilandelayo kukulungiselela umbhobho. Oku kubandakanya ukucoca isiphelo sombhobho ukususa naluphi na ukungcola, inkunkuma, okanye ukubola okunokuchaphazela imfezeko yoqhagamshelo. Kubalulekile ukuqinisekisa ukuba isiphelo sombhobho sicocekile kwaye sigudile ukubonelela ngomphezulu ofanelekileyo ukuze iflange ivaleke ngokuchasene nayo.
Emva kokuba zombini i-flange kunye nombhobho zilungiswe, kubalulekile ukukhetha i-gasket efanelekileyo kwisicelo esithile. Igasket kufuneka ihambelane nolwelo oluthuthwa ngenkqubo yemibhobho kwaye kufuneka ikwazi ukumelana nobushushu kunye neemeko zoxinzelelo lwenkqubo.. Emva kokuba i-gasket ikhethiwe, kufuneka ibekwe ngononophelo ebusweni bomnye weeflange ukuqinisekisa isitywina esifanelekileyo.
ISikhokelo seNyathelo ngeNyathelo soFakelo lweFlange
Isinyathelo sokuqala sokufakela i-flange kukulungelelanisa iiflange kunye neziphelo zepayipi. Oku kubandakanya ukuqinisekisa ukuba imingxuma yebholithi kwiiflanges ihambelana enye kwenye kunye nemingxuma yebholi kumbhobho.. Ulungelelwaniso olululo lubalulekile ekuqinisekiseni uqhagamshelo olukhuselekileyo nolungenakuvuza.
Emva kokuba iiflange zilungelelanisiwe, inyathelo elilandelayo kukufaka iibholiti kwimingxuma yebholiti kwenye yeeflange. Kubalulekile ukusebenzisa ibakala elifanelekileyo kunye nobukhulu beebholiti ngokusekelwe kuxinzelelo kunye neemfuno zokushisa kwenkqubo yokubhobhoza. Iibholiti kufuneka zifakwe kwi-flange kunye nemingxuma yombhobho, ngamandongomane abekwe kwelinye icala ukuze akhuseleke endaweni.
Emva kokufaka zonke iibholiti kunye namantongomane, kubalulekile ukuwaqinisa ngokulandelelana okuthe ngqo ukuqinisekisa ukusabalalisa ngokulinganayo koxinzelelo kwi-gasket. Oku kubandakanya ukuqiniswa kwebholithi nganye kancinane ngexesha kwipateni yecrisscross de zonke zithobe.. Nje ukuba zonke iibholithi zilungile, kufuneka ziqiniswe ngakumbi kusetyenziswa isitshixo setorque ukufikelela kwixabiso elikhankanyiweyo letorque yeflange ethile kunye nendibaniselwano yegasket..
Ukuxazulula iingxaki kwiMiba yoFakelo lweFlange eqhelekileyo
Nangona ukulungiswa ngononophelo kunye nokufakwa, imiba isenokuthi ivele ngexesha lofakelo lweflange. Umba omnye oqhelekileyo kukuvuza kunxibelelwano lweflange, enokubangelwa kukulungelelaniswa okungafanelekanga, itorque yebholithi eyaneleyo, okanye i-gasket eyonakeleyo. Ukucombulula lo mba, kubalulekile ukuhlola ngokucophelela uxhulumaniso lwe-flange nayiphi na imiqondiso yokungahambi kakuhle okanye umonakalo, kunye nokuqinisekisa ukuba zonke iibholithi zitotshi ngokufanelekileyo.
Omnye umba oqhelekileyo ngexesha lofakelo lwe-flange kukuqhekeka kwe-bolt okanye ukuhluthwa. Oku kunokwenzeka ukuba iibholiti zigqithisekile okanye azihambelani kakuhle nemingxuma yebholithi kwiiflange.. Ukuthintela lo mba, kubalulekile ukulandela ngononophelo amaxabiso e-torque achaziweyo kwi-flange ethile kunye ne-gasket indibaniselwano, kunye nokuqinisekisa ukuba zonke iibholithi zilungelelaniswe ngokufanelekileyo phambi kokuqiniswa.
Iingcebiso zokugcina iFlange Ingqibelelo
Nje ukuba iflange ifakwe ngempumelelo, kubalulekile ukuthatha amanyathelo ukugcina ingqibelelo yayo ekuhambeni kwexesha. Enye inkalo ebalulekileyo yokugcina ingqibelelo yeflange kukuhlolwa rhoqo kunye nokugcinwa. Oku kubandakanya ukujonga ngokubonakalayo umdibaniso weflange naziphi na iimpawu zokuvuza okanye umonakalo, ngokunjalo nokujonga amaxabiso etorque yebholithi ukuqinisekisa ukuba ahlala ngaphakathi kwemida ethile.
Elinye icebiso lokugcina ingqibelelo yeflange kukubeka esweni iimeko zokusebenza ezifana nobushushu kunye noxinzelelo lokuqinisekisa ukuba zihlala ngaphakathi kwemida yoyilo.. Iiflange zenzelwe ukumelana neemeko ezithile zokusebenza, ngoko ke kubalulekile ukubeka esweni ezi meko ukuthintela umonakalo okanye ukungaphumeleli.
Ubuchule boBugcisa boFakelo lweFlange
Ukufakwa kweFlange kuyinkalo ebalulekileyo yokwakhiwa kwenkqubo yemibhobho kunye nokugcinwa. Ukuqonda iintlobo ezahlukeneyo zeeflange, ukukhetha izixhobo ezifanelekileyo kunye nezixhobo, ukulungiselela zombini i-flange kunye nombhobho wofakelo, ilandela inyathelo ngenyathelo isikhokelo sofakelo, ukulungisa iingxaki eziqhelekileyo, kunye nokugcina ingqibelelo yeflange zizinto zonke eziyimfuneko zokulawula ubugcisa bofakelo lweflange. Ngokulandela ezi zikhokelo kunye nokuthatha amanyathelo asebenzayo ukuqinisekisa ukufakela nokugcinwa okufanelekileyo, abantu ngabanye banokuqinisekisa ukuba iinkqubo zabo zemibhobho zisebenza ngokukhuselekileyo nangempumelelo kwiminyaka ezayo.
