Ni ubuhe bwoko bwa flanges buhari

Intangiriro yibanze ya flange
Umuyoboro wa flanges hamwe na gasketi zabo hamwe nugufatisha hamwe hamwe byitwa guhuza flange.
Gusaba:
Flange ihuriweho nubwoko bwibikoresho bikoreshwa mugushushanya.Nigice cyingenzi cyibishushanyo mbonera, ibyuma bifata imiyoboro hamwe na valve, kandi nigice cyingenzi cyibikoresho nibikoresho (nka manhole, igipimo cyikirahure cyerekana, nibindi).Byongeye kandi, ingingo ya flange ikoreshwa kenshi mubindi bice, nk'itanura ryinganda, ubwubatsi bwumuriro, gutanga amazi namazi, gushyushya no guhumeka, kugenzura byikora, nibindi.
Imiterere y'ibikoresho:
Ibyuma byahimbwe, WCB ibyuma bya karubone, ibyuma bidafite ingese, 316L, 316, 304L, 304, 321, ibyuma bya chrome-molybdenum, ibyuma bya chrome-molybdenum-vanadium, icyuma cya molybdenum titanium, umurongo wa reberi, ibikoresho bya fluor.
Ibyiciro:
Flat welding flange, flange flange, butt welding flange, impeta ihuza flange, sock flange, hamwe nisahani ihumye, nibindi.
Ubuyobozi bukuru:
Hariho urutonde rwa GB (urwego rwigihugu), urukurikirane rwa JB (ishami ryubukanishi), urukurikirane rwa HG (ishami ryimiti), ASME B16.5 (igipimo cyabanyamerika), BS4504 (igipimo cyu Bwongereza), DIN (igipimo cy’Ubudage), JIS (igipimo cy’Ubuyapani).
Sisitemu mpuzamahanga ya flange flange:
Hariho amahame abiri yingenzi mpuzamahanga ya pipe flange, aribyo sisitemu yu Burayi ya flange ihagarariwe na DIN yo mu Budage (harimo n'icyahoze ari Leta Zunze Ubumwe z'Abasoviyeti) hamwe na sisitemu yo muri Amerika imiyoboro ihagarariwe na ANSI y'Abanyamerika.

1. Ubwoko bw'isahani iringaniye
akarusho:
Nibyiza kubona ibikoresho, byoroshye gukora, bidahenze kandi bikoreshwa cyane.
Ibibi:
Bitewe no gukomera kwayo, ntigomba gukoreshwa muri sisitemu yo gutunganya imiyoboro ya chimique hamwe nibisabwa kubitangwa nibisabwa, gutwikwa, guturika no kurwego rwinshi rwa vacuum, no mubihe bibi cyane.
Ubwoko bwa kashe ifite ubuso buringaniye.
2. Flat welding flange hamwe nijosi
Kunyerera-gusudira flange hamwe nijosi ni ibya sisitemu isanzwe yigihugu.Nuburyo bumwe bwa flange isanzwe yigihugu (izwi kandi nka GB flange) nimwe muribisanzwe bikoreshwa mubikoresho cyangwa umuyoboro.
akarusho:
Kwishyiriraho kurubuga biroroshye, kandi inzira yo gusudira ikariso irashobora kuvaho
Ibibi:
Uburebure bw'ijosi bwa slip-on welding flange hamwe nijosi ni buke, bitezimbere ubukana nubushobozi bwa flange.Ugereranije na butt welding flange, akazi ko gusudira ni nini, gukoresha inkoni yo gusudira ni byinshi, kandi ntibishobora kwihanganira ubushyuhe bwinshi n’umuvuduko mwinshi, kunama inshuro nyinshi no guhindagurika.
3. Ijosi rya butt welding flange
Ubuso bwo gufunga ijosi buto yo gusudira flange harimo:
RF, FM, M, T, G, FF.
akarusho:
Ihuza ntabwo ryoroshye guhindura, ingaruka zo gufunga ni nziza, kandi irakoreshwa cyane.Irakwiriye imiyoboro ifite ihindagurika ryinshi ryubushyuhe cyangwa umuvuduko, ubushyuhe bwinshi, umuvuduko mwinshi nubushyuhe buke, ndetse no kumiyoboro itwara itangazamakuru rihenze, ibitangazamakuru byaka kandi biturika, hamwe na gaze yuburozi.
Ibibi:
Ijosi butt-welding flange nini, nini, ihenze, kandi biragoye kuyishiraho no kuyishakisha.Kubwibyo, biroroshye guhita mugihe cyo gutwara.
4. Socket welding flange
Socket welding flangeni flange yasuditswe numuyoboro wicyuma kuruhande rumwe hanyuma ugahinduka kurundi ruhande.
Ubwoko bwa kashe:
Isura yazamuye (RF), isura yuzuye na convex (MFM), tenon na groove face (TG), impeta ihuriweho (RJ)
Igipimo cyo gusaba:
Ubwato hamwe nigitutu, peteroli, imiti, kubaka ubwato, imiti, metallurgie, imashini, gushyira kashe ibiryo byinkokora nizindi nganda.
Bikunze gukoreshwa mumiyoboro hamwe na PN ≤ 10.0MPa na DN ≤ 40.
5. Urupapuro rudodo
Urupapuro rudodo ni urudodo rudasudwe, rutunganya umwobo w'imbere wa flange mumurongo wumuyoboro kandi ugahuza numuyoboro.
akarusho:
Ugereranije no gusudira neza cyangwa gusudira,urudodoifite ibiranga uburyo bworoshye bwo kuyishyiraho no kuyitaho, kandi irashobora gukoreshwa kumiyoboro imwe itemewe gusudira kurubuga.Amavuta ya flay flange afite imbaraga zihagije, ariko ntabwo byoroshye gusudira, cyangwa imikorere yo gusudira ntabwo ari nziza, flange yomutwe nayo irashobora gutoranywa.
Ibibi:
Iyo ubushyuhe bwumuyoboro buhindutse cyane cyangwa ubushyuhe buri hejuru ya 260 ℃ no munsi ya - 45 ℃, birasabwa kudakoresha flange yomutwe kugirango wirinde kumeneka.
6. Impumyi
Bizwi kandi nka flange igifuniko hamwe nisahani ihumye.Ni flange idafite umwobo hagati yo gufunga imiyoboro.
Igikorwa ni kimwe n'icy'umutwe wasuditswe hamwe n'umutwe wa pipe ya pipe, usibye koimpumyin'umuyoboro w'udodo twa podiyumu urashobora gukurwaho umwanya uwariwo wose, mugihe umutwe wasuditswe udashobora.
Igipfukisho cya flange hejuru yikimenyetso:
Flat (FF), isura yazamuye (RF), isura ya convex na convex (MFM), tenon na groove face (TG), impeta ihuriweho (RJ)
