Large m'mimba mwake flange monga flange wamba, chifukwa chitha kugwiritsidwa ntchito zosiyanasiyana zochitika ndi ubwino wa zotsatira zabwino ndi makampani okondedwa, mankhwala chimagwiritsidwa ntchito makina ndi mafakitale mankhwala ndi mafakitale ena, tiyeni opanga DHDZ flange kuyambitsa zofunikira za msonkhano ndi zomangamanga zotsutsana ndi dzimbiri.

I. Msonkhano mfundo ndi zofunika za flanges lalikulu awiri
1. Posonkhanitsa ma flanges, mabowo a bolt a flanges okwera ayenera kugwirizanitsidwa ndi mabowo a bolt omwe amafanana ndi ma flanges okhazikika komanso ofanana ndi ma flanges okhazikika. Kupatuka sikuyenera kukhala kwakukulu kuposa 1.5 ndi 2mm yakunja kwa ma flanges.
2. Yang'anani ndi kukonza momwe flange ilili kuchokera kumanzere ndi kumanja ndi mapazi 90, ndipo malizitsani kuwotcherera kwa malo ndikukonza m'mimba mwake wa flange kupyola nsonga yachitatu ndi yachinayi mukawotcherera malo.
3. Posankha ma flanges ofananira a zida kapena ma valve, chisamaliro chiyenera kutengedwa kuti muwone ngati ma flanges a zida zoyambira kapena ma valve ndi ofanana ndi omwe amagwiritsidwa ntchito papaipi.
4. Posonkhanitsa ma flanges opangidwa ndi lathyathyathya, mapeto a chitoliro ayenera kuikidwa 2/3 ya makulidwe a mkati mwa flange, ndiyeno sungani chowotcherera ku chitoliro. Pa chitoliro chopingasa, ikani chowotcherera kuchokera pamwamba, kenako yang'anani mawonekedwe a flange kuchokera mbali zosiyanasiyana ndi masikweya mita 90 kuti malo osindikizira azikhala molunjika ku mzere wapakati wa chitoliro, kenako ikani weld pansi pa malo.
5. Musanasonkhanitse flange, yeretsani pamwamba pa flange, makamaka malo osindikizira.

Awiri, ntchito ndondomeko ndi makhalidwe a lalikulu awiri flange odana dzimbiri zomangamanga
Kusindikiza corrosion inhibitor kwa flange chilolezo chodzaza ndi mainchesi akulu. Matani pepala (transparent) tepi m'mphepete mwa flange kuteteza flange kukhala zauve pamene jekeseni dzimbiri inhibitor; Tsekani ndi kudzaza chilolezo cha flange ndi corrosion inhibitor kuti muwonetsetse kuti chilolezo cha flange chadzaza ndi kusindikiza corrosion inhibitor.
Mukadzaza phokoso la flange ndi corrosion inhibitor, gwiritsani ntchito putty scraper kuti mupukutire pamtunda wosalala motsatira njira yozungulira, kuti kusiyana ndi m'mphepete mwa flange mu ndege yomweyo. Dulani mbali zonse za tepi.
Ngati mugwiritsa ntchito flange anticorrosion zonona, muyenera kugwiritsa ntchito mpeni kudula flange anticorrosion kirimu mu n'kupanga yopapatiza, ndiyeno malinga ndi m'lifupi mwa flange kusiyana, mwachindunji mudzaze flange kusiyana ndi dzanja. Dinani pansi pamene mukudzaza.
Clearance ndi pamwamba mankhwala lalikulu awiri flange. Chotsani dzimbiri pa chilolezo cha flange ndi zomangira ndi burashi; Chotsani chilolezo cha flange ndi mpweya wothinikizidwa; Ngati chochotsa mankhwala chikugwiritsidwa ntchito, yesani ngati chochotsa mankhwala chidzakhudza chisindikizo cha flange.
Ngati mukukayika, ndi bwino kuti musagwiritse ntchito njira za mankhwala; Pukutani pamwamba ndi sandpaper kapena thonje kuti mukwaniritse muyezo wa ST2.
