Amafulethi akhiwebasungulwa ngesisekelo se-castamalangabi ensimbi, futhi amandla awo aphakeme kakhulu kunokuphonsaamalangabi ensimbi, ukuze izingxenye ezixhumene namapayipi zixhumeke ekugcineni kwepayipi.I-Butt Welding FlangeUhlobo lokufaneleka kwepayipi, olusho i-flange ngentamo kanye nokuguqulwa kwepayipi okujikelezayo kanye nokuxhumeka kwe-butt welding ngepayipi. Akulula ekuguqukeni, ukubekwa uphawu okuhle, okusetshenziswa kabanzi, kufanelekile ekuguqukeni kwengcindezi noma okushisa okuphezulu, ingcindezi yokushisa eshibhile, inzuzo ingcindezi eshibhile ye-accound ayidluli nge-2.5mpa; Iphinde isetshenziselwe ukudlulisela imithombo yezindaba ebizayo, evuthayo kanye nokuqhuma epayipini, futhi ingcindezi yokuphakama imayelana ne-PN16MPA.
Le khasiowakhelwayoAma-Flanges agcwele, futhi ama-bolts (aqukethe ikhanda nesikulufa) abamba ama-flanges amabili ndawonye. Amafulethi akhiwe avalwe ngama-gaskets.Sakhiwe sakhiweUkufakwa kwamapayipi kubhekisele kulabo abanayoamafulethi akhiwe (ama-flangesnoma amalunga). Kungaphonswa, kuthathwe noma kufakwe insimbi. Ukuxhumeka kwe-Flange kuqukethe ama-flanges abhangqa, i-gasket kanye nama-bolts namantongomane amaningi. I-gasket ibekwa phakathi kwezindawo zokubopha ama-flating ezimbili, futhi ngemuva kokuqinisa isikulufa, ingcindezi ethile ebusweni be-gasket igcwele ngemuva kokuthola inani elithile, futhi indawo engalingani endaweni yokubopha igcwalisiwe, ukuze ukuxhumana kungavuthiwe.

Kunezinhlobo ezintathu zokwakha i-Flange Vula ingaphezulu: indawo yokubekwa endizeni, efanelekile ingcindezi ayikho phezulu, okuphakathi (okunqumayo (izinto ezinqumayo) izikhathi ezingezona ezinobuthi; Indawo yokubekwa uphawu ye-concave ne-convex, ilungele izikhathi eziphakeme zokucindezela; I-Sealing Surface of Tenon (S ǔ n) i-Groove, ilungele ukuguquguquka okuvuthayo, okuqhumayo, okunobuthi okuphakathi nendawo okucindezelayo kwezikhathi eziphakeme. I-Gasket iyindandatho eyenziwe ngezinto ezibonakalayo ezingakhiqiza i-deformation yepulasitiki futhi inamandla athile.
Ama-gaskets amaningi ancishiswa amapuleti angewona ama-metallic, noma enziwe ngamafekthri abuchwepheshe ngokuya ngosayizi obekiwe (i-asbestos ibhodi yensimbi, njll. Kukhona nohlobo lwe-gasket evumayo eyenziwe ngebhande lensimbi elincanyana nebhande le-asbestos ndawonye. I-Flange ibizwa nangokuthi i-Flange Flange. Ingxenye exhuma ipayipi kupayipi lixhumeke ekugcineni kwepayipi. Kukhona izimbobo eziseFlange naseBolts zibamba amafulethi amabili ndawonye. Izimpawu ze-gasket phakathi kwama-flanges. I-Flange iyingxenye eyenziwe nge-disk, evame kakhulu ebunjiniyela bePipeline. Ama-Flanges asetshenziswa ngababili.

E-Pipeline Engineering, i-Flange isetshenziselwa ukuxhumana kwepayipi. Ekupheleni lapho amapayipi amabili adinga ukuxhunywa, faka i-flange ngayinye. I-Fire Flange ingasetshenziselwa amapayipi okucindezela okuphansi, futhi i-welded flange ingasetshenziselwa ingcindezi ye-4 kg. Beka i-gasket phakathi kwalezi zinto ezimbili bese uyibolula phansi. Abakhiqizi be-Flange bavame ukusebenzisa ama-bolts ukuxhuma izindiza ezimbili ku-perifery ngezingxenye ezifanayo ezivaliwe, ezivame ukwaziwa ngokuthi "i-flange", lolu hlobo lwezingxenye, lolu hlobo lwezingxenye lungabizwa ngokuthi "izingxenye ze-flange". I-gasket ejwayelekile yenjoloba ilungele umcimbi lapho izinga lokushisa liphansi kune-120 ℃; I-Asbestos rubber gasket ilungele umphunga wamanzi (okukhulunywa ngawo njengokushisa kwamanzi) kungaphansi kwama-450 ℃, izinga lokushisa likawoyela lingaphansi kwezikhathi ezingama-550. Emishini yengcindezi ephezulu (SHEBei) kanye namapayipi, ama-gaskets ensimbi wethusi, i-aluminium (al), cha. Insimbi eyi-10, insimbi engenasici Ububanzi bokuxhumana buka-gasket wengcindezi ephezulu kanye nokubekwa uphawu okuphansi kuncane kakhulu (ukuxhumana okuqondile), kanye nokuqedwa kokusebenza kokubekwa uphawu kwe-saingbuso kanye ne-gasket kuphezulu.
