Kuyini Ukuxhumana Kwe-Flange

Ukuxhumeka kwe-Flange, njengoba igama lisho, liyisihlanganisi esixhuma ngokuqinile ama-flanges amabili emikhawulweni yomibili yepayipi.Lokhu okuhlanganisiwe kulula ukunqamula futhi kunokusebenza okuhle kokubekwa uphawu.

1 Kuyini ukuxhumana kwe-flange
Ukuxhumeka kwe-Flange empeleni kuyindlela yokuhlanganisa exhuma amapayipi komunye nomunye, futhi futhi kuyindlela yokuxhuma, ikakhulukazi ngokulungisa ukufakwa kwamapayipi noma amapayipi amabili ngokulandelana, bese phakathi kwamaphaphu amabili ngokulandelana, bese kuthi phakathi kwamaphaneli amabili.Gcoba iwasha ye-flange, futhi ekugcineni uqinise ama-flange ngamabhawodi ukuze ahlangane aqine.Lolu hlobo lokuxhuma phakathi kwamapayipi lusetshenziswa kakhulu kumapayipi ensimbi asakazwayo namapayipi anerabha.

2 Ukuxhumana kwe-flange
Izindlela zokuxhumeka ze-Flange zivame ukwahlukaniswa ngezinhlobo ezinhlanu: Ukushiswa kwe-Flat, Butt Welding, iSocket Welding, umkhono oxegayo nentambo.
Okwesine kokuqala kuchazwe ngokuningiliziwe ngezansi:
I-Flat Welding: Ungqimba lwangaphandle kuphela olushintshiwe, futhi ungqimba lwangaphakathi aludingeki;Ngokuvamile isetshenziswa kumapayipi aphakathi nendawo futhi aphansi, futhi ingcindezi yokuqothuka yepayipi kufanele ibe ngaphansi kwama-2.5mpa.Kunezinhlobo ezintathu zezindawo zokubekwa uphawu kwama-flat welding flanges, okungukuthi uhlobo olubushelelezi, uhlobo lwe-concave-convex kanye nohlobo lwe-yotie-and-grove.Phakathi kwazo, uhlobo olubushelelezi luyasetshenziswa kabanzi, futhi lungabizi futhi luyabiza kakhulu.
Ukushisela izinqe: izingqimba zangaphakathi nezingaphandle ze-flange kufanele zishiselwe, ngokuvamile zisetshenziswe kumapayipi anomfutho ophakathi nendawo nophezulu, futhi ukucindezela okulinganiselwe kwepayipi kuphakathi kuka-0.25 no-2.5MPa.Indawo yokuvala yendlela yokuxhumana ye-butt welding flange i-concave futhi i-convex, futhi ukufakwa kuyinkimbinkimbi kakhulu, ngakho-ke izindleko zabasebenzi, indlela yokufaka kanye nezindleko zezinto ezisizayo ziphezulu uma kuqhathaniswa.
I-Socket Welding: Ngokuvamile isetshenziswa emapayipi ngengcindezi yokuqothuka engaphansi noma ilingana ne-10.0MPA kanye nobubanzi bendawo engaphansi noma elingana ne-40mm.
I-Sleeve Exegayo: Ngokuvamile isetshenziswa kumapayipi anengcindezi ephansi kepha i-complocinative medium, ngakho-ke lolu hlobo lwe-flange lunokuphikiswa okuqinile kokugqwala, futhi impahla yensimbi engenasici.

3 Inqubo yokuxhuma i-Flange
Inqubo yokuxhumana ye-Flange imi ngalendlela elandelayo:
Okokuqala, ukuxhumana phakathi kwe-flange nepayipi kufanele kuhlangabezane nezidingo ezilandelayo:
1. Isikhungo sepayipi futhi i-flange kufanele ibe kulayini ofanayo ovundlile.
2. Isikhungo sepayipi kanye nendawo yokuvala ye-flange yakha umumo oqondile we-90-degree.
3. Ukuma kwamabhawodi e-flange epayipini kufanele kufane.

Okwesibili, i-padding flange gasket, izidingo zimi kanje:
1.Ephayiphini elifanayo, ama-gaskets akhethiwe ama-flange anengcindezi efanayo kufanele afane, ukuze kube lula ukushintshaniswa kwesikhathi esizayo.
2. Ngamapayipi asebenzisa amashidi enjoloba, kungcono ukukhetha ama-gaskets enjoloba, njengemigqa yamanzi.
3. Isimiso sokukhethwa kwe-gasket yilena: Khetha eduze ngangokunokwenzeka ububanzi obuncane, okuyisimiso okufanele silandelwe esibonelweni sokuthi i-gasket ngeke ichotshozwa.

1. Bheka ukuthi ukucaciswa kwama-flanges, ama-bolts kanye nama-gaskets ahlangabezana nezidingo.
2. Ingaphezulu lokubekwa uphawu kufanele ligcinwe libushelelezi futhi licocekile ngaphandle kwemingcele.
3. Intambo ye-bolt kufanele iphelele, akufanele kube namaphutha, futhi ukufakwa kufanele kube ngokwemvelo.
4. Ukuthungwa kwe-gasket kufanele kube nezimo, kungabi lula ukuya eminyakeni yobudala, futhi ingaphezulu akufanele lilimele, imibimbi, ukuklwebheka nezinye iziphambeko.
5. Ngaphambi kokuqopha i-flange, i-flange kufanele ihlanzwe ukuze isuse uwoyela, uthuli, ukugqwala kanye nezinye izisulu, futhi umugqa wokubekwa uphawu kufanele asuswe.

1. Indawo evuthayo ye-flange ingukuthi i-perpendicular enkabeni yepayipi.
2. Ama-bolts we-specifition efanayo anendlela efanayo yokufaka.
3. Isikhundla sokufakwa kwe-flange efakwe kwipayipi yegatsha kufanele ibe ngaphezu kuka-100 mm ukusuka odongeni lwangaphandle lwe-riseer, futhi ibanga ukusuka odongeni lwesakhiwo kufanele libe ngu-200 mm noma ngaphezulu.
4. Ungangcwabi i-flange ngokuqondile ngaphansi komhlaba, kulula ukugqwala.Uma kufanele kungcwatshwe ngaphansi komhlaba, kuyadingeka ukwenza ukwelashwa kwe-anti-corrosion.
