I-Flange (bheka i-flange JBZQ 4187-97) ibizwa nangokuthi i-flange noma i-flange.Izingxenye ezixhuma ipayipi nepayipi komunye nomunye, zixhunywe ekugcineni kwepayipi.Kunezimbobo ku-flange, futhi amabhawodi axhuma ngokuqinile ama-flange amabili.Ama-flanges avaliwe ngama-gaskets.Ukufakwa kwamapayipi e-Flange kubhekisela ekufakweni kwamapayipi ngama-flanges (ama-flanges noma amazwe).Ingaphonswa, igoqwe noma ishiselwe.
Ukuxhumeka kwe-Flange (i-flange, i-joint) iqukethe ama-flanges, i-gasket nama-bolts amaningana namantongomane.I-gasket ibekwe phakathi kwezindawo zokuvala zama-flange amabili.Ngemuva kokuthi i-nut iqinisiwe, ingcindezi ethile ebusweni be-gasket ifinyelela inani elithile bese ikhubaza, futhi igcwalisa ukungalingani endaweni yokuvala ukuze wenze uxhumano luqine.Ukuxhumeka kwe-Flange kuwukuxhumana okungalahleka.Ngokusho kwezingxenye ezixhunyiwe, ingahlukaniswa ibe yi-container flange kanye ne-pipe flange.Ngokusho kohlobo lwesakhiwo, kukhona i-flange ehlanganisiwe, i-loop flange kanye ne-threaded flange.Ama-flange ajwayelekile ahlanganisa ama-flange welding flat kanye nama-flange welding we-butt.Ama-flat welding flange anokuqina okubuthakathaka futhi afanele izikhathi lapho i-pressure p≤4MPa.I-butt welding flanges, eyaziwa nangokuthi i-high neck flanges, inokuqina okuphezulu futhi ifanele izikhathi ezinengcindezi ephakeme kanye nezinga lokushisa.
Kunezinhlobo ezintathu zezindawo zokuvalwa kwe-flange: indawo eyisicaba yokuvala, elungele izikhathi ezinomfutho ophansi kanye nendawo engenabuthi.i-concave-convex sealing surface, ilungele izikhathi ezinengcindezi ephakeme kancane, imidiya enobuthi kanye nezikhathi zokucindezela okukhulu.I-gasket iyindandatho eyenziwe ngezinto ezingakhiqiza ukuguqulwa kwepulasitiki futhi inamandla athile.Iningi lama-gaskets lisikwa kumapuleti angewona awensimbi, noma enziwe amafektri ochwepheshe ngokuya ngosayizi oshiwo.Izinto zokwakha amapuleti enjoloba ye-asbestos, amapuleti e-asbestos, amapuleti e-polyethylene, njll.Kukhona futhi i-gasket efakwe ngensimbi eyenziwe ngezinto ezigoqwe ezingezona ezensimbi.kukhona futhi i-gasket yesilonda eyenziwe ngemicu yensimbi emincane nemicu ye-asbestos.Ama-gasket enjoloba ajwayelekile afanele izikhathi lapho izinga lokushisa lingaphansi kuka-120°C.ama-gasket enjoloba ye-asbestos afanele izikhathi lapho izinga lokushisa lomhwamuko lingaphansi kuka-450°C, izinga lokushisa likawoyela lingaphansi kuka-350°C, futhi umfutho ungaphansi kuka-5MPa.Okumaphakathi, okuvame ukusetshenziswa kakhulu yibhodi le-asbestos elimelana ne-asidi.Emishinini yokucindezela okukhulu nasemapayipini, kusetshenziswa ama-gaskets ensimbi amise okwelensi noma okunye okwenziwe ngethusi, i-aluminium, insimbi enguNo. 10, nensimbi engagqwali.Ububanzi bokuxhumana phakathi kwe-gasket ephezulu yokucindezela kanye nendawo yokuvala incane kakhulu (ukuxhumana komugqa), futhi ukuphela kokucubungula kwendawo yokuvala kanye ne-gasket kuphakeme kakhulu.
Ukuhlukaniswa kwe-Flange: Ama-Flange ahlukaniswe ama-flange anentambo (anezintambo) nama-flange welding.I-diameter encane enengcindezi ephansi ine-wire flange, futhi i-high-pressure ne-low-pressure diameters enkulu isebenzisa ama-welding flange.Ubukhulu bepuleti ye-flange yezingcindezi ezahlukene kanye nobubanzi kanye nenani lama-bolts okuxhuma kuhlukile.Ngokwamazinga ahlukene okucindezela, amaphedi e-flange nawo anezinto ezihlukene, kusukela kumaphedi e-asbestos anengcindezi ephansi, amaphedi e-asbestos anengcindezi ephezulu kuya kumaphedi ensimbi.
1. Ihlukaniswe ngezinto ezibonakalayo zibe yi-carbon steel, cast steel, alloy steel, insimbi engagqwali, ithusi, i-aluminium alloy, ipulasitiki, i-argon, i-ppc, njll.
2. Ngokwendlela yokukhiqiza, ingahlukaniswa ibe yi-flange engumgunyathi, i-cast flange, i-welding flange, i-flange egoqiwe (imodeli enkulu kakhulu) 3. Ngokwezinga lokukhiqiza, ingahlukaniswa ngokwezinga likazwelonke (okujwayelekile koMnyango Wezamakhemikhali Imboni, izinga likaphethiloli, izinga lamandla kagesi) , American Standard, German Standard, Japanese Standard, Russian Standard, njll.
Amasistimu amaningana wamazinga we-international pipe flange:
1. Ukuxhumeka kwe-Flange noma i-flange joint ibhekisela ekuxhumekeni okugoqekayo okuhlanganisa ama-flange, ama-gaskets nama-bolt axhunywe komunye nomunye njengesakhiwo sokuvala esihlanganisiwe.Ama-flange amapayipi abhekisela kuma-flange asetshenziselwa ukufaka amapayipi ekufakweni kwamapayipi.Emishinini, kubhekiselwa kuma-flange wokungena nokuphuma kwempahla.
