I-flange enkulu yobubanzi njenge-flange evamile, ngoba ingasetshenziswa ezikhathini ezahlukene kanye nezinzuzo zomphumela omuhle embonini ethandwayo, umkhiqizo usetshenziswa kabanzi embonini yemishini namakhemikhali nakwezinye izimboni, ake abakhiqizi be-DHDZ flange bethule. izidingo zesimiso somhlangano kanye nokwakhiwa kwe-anti-corrosion.

I. Umgomo wokuhlanganisa kanye nezidingo zama-flange amakhulu
1. Uma uhlanganisa i-pair of flanges, izimbobo ze-bolt ze-flanges ezikhuphukayo kufanele zihambisane nezimbobo ze-bolt ezihambisana nama-flanges ahleliwe futhi zihambisane nama-flanges ahleliwe. Ukuchezuka akufanele kube kukhulu kuno-1.5 no-2mm we-diameter yangaphandle yama-flange.
2. Hlola futhi ulungise ukuma kwe-flange ukusuka ohlangothini lwesobunxele nakwesokudla ngamafidi-skwele angu-90, bese uqedela ukushisela indawo futhi ulungise ububanzi be-flange ngephuzu lesithathu nelesine ngemva kokushisela indawo.
3. Lapho kukhethwa ama-flange afanayo emishini noma ukuhlanganiswa kwama-valve, kufanele kuqashelwe ukuthi ama-flange empahla yokuqala noma ukuhlanganiswa kwama-valve afana nalawo asetshenziswa epayipini.
4. Uma uhlanganisa ama-flange ane-welded flat, ukuphela kwepayipi kufanele kufakwe u-2/3 wobukhulu bobubanzi obungaphakathi be-flange, bese ubona ukushisela i-flange kwipayipi. Epayipini elivundlile, beka i-weld kusuka phezulu, bese uhlola ukuma kwe-flange ukusuka ezinkomba ezahlukene ngamafidi-skwele angama-90 ukuze indawo yokuvala ihambisane nomugqa omaphakathi wepayipi, bese ubeka ukushisela ngezansi kwendawo.
5. Ngaphambi kokuhlanganisa i-flange, hlanza indawo ye-flange, ikakhulukazi indawo yokuvala.

Okwesibili, inqubo yokusebenza kanye nezici zokwakhiwa okukhulu kwe-flange anti-corrosion
Ukuvala i-corrosion inhibitor yokugcwalisa i-flange clearance yobubanzi obukhulu. Namathisela itheyiphu yephepha (esobala) onqenqemeni lwe-flange ukuvimbela i-flange ukuthi ingangcoli lapho ujova i-corrosion inhibitor; Vala futhi ugcwalise imvume ye-flange nge-corrosion inhibitor ukuze uqinisekise ukuthi imvume ye-flange igcwele i-sealing corrosion inhibitor.
Ngemva kokugcwalisa igebe le-flange nge-corrosion inhibitor, sebenzisa i-putty scraper ukuze upholise ubuso bushelelezi ngokuhambisana nesiqondiso se-circumferential, ukuze igebe kanye nomphetho we-flange endizeni efanayo. Susa izinhlangothi zombili ze-tape.
Uma usebenzisa i-flange anticorrosion cream, udinga ukusebenzisa ummese ukusika ukhilimu we-anticorrosion we-flange ube yimichilo emincane, bese ngokusho kobubanzi begebe le-flange, ugcwalise ngokuqondile igebe le-flange ngesandla. Cindezela phansi uma ugcwalisa.
Ukususwa kanye nokwelashwa kwendawo ye-flange enkulu yobubanzi. Susa ukugqwala ku-flange clearance kanye nezikulufa ngebhulashi; Hlanza imvume ye-flange ngomoya ocindezelwe; Uma kusetshenziswa isikhiphi samakhemikhali, hlola ukuthi isikhiphi samakhemikhali sizothinta uphawu lwe-flange.
Uma ungabaza, kunconywa ukuthi ungasebenzisi izindlela zamakhemikhali; Sula indawo ye-flange nge-sandpaper noma intambo kakotini ukuze uhlangabezane nezinga le-ST2.
