I-RF - Ubuso Obuphakanyisiwe

I-face flange ephakanyisiwe iwuhlobo oluvame kakhulu olusetshenziswa ekusetshenzisweni kwezitshalo, futhi kulula ukuyibona. Kubizwa ngokuthi ubuso obuphakanyisiwe ngenxa yokuthi izindawo ze-gasket ziphakanyiswe ngaphezu kobuso bendilinga ebophayo. Lolu hlobo lobuso luvumela ukusetshenziswa kwenhlanganisela ebanzi yemiklamo ye-gasket, okuhlanganisa izinhlobo zeshidi lendandatho eyisicaba kanye nezinhlanganisela zensimbi ezifana nesilonda esivunguzayo kanye nezinhlobo eziboshwe kabili.

Inhloso ye-RF flange ukugxilisa ingcindezi eyengeziwe endaweni encane ye-gasket bese ngaleyo ndlela kukhuphule amandla okubamba ingcindezi yelunga. Ububanzi nobude kuku-ASME B16.5 okuchazwe, ngesigaba sokucindezela nobubanzi. Isilinganiso sokucindezela kwe-flange sinquma ubude bobuso obuphakanyisiwe.

Ukuqedwa kobuso be-flange okujwayelekile kwe-ASME B16.5 RF flanges kungu-125 kuya ku-250 µin Ra (3 kuya ku-6 µm Ra).

M - Ubuso Bendoda

FM- Ubuso Bowesifazane

Ngalolu hlobo ama-flange nawo kufanele afaniswe. Ubuso obunye be-flange bunendawo edlulela ngale kobuso obujwayelekile be-flange (Owesilisa). Enye i-flange noma i-flange yokukhwelana inokucindezeleka okufanayo (Owesifazane) okufakwe ebusweni bayo.
Ubuso besifazane buyi-3/16-intshi ukushona, ubuso bowesilisa buyi-1/4-intshi ukuphakama, futhi kokubili kuqediwe ngokushelela. Ububanzi obungaphandle bobuso besifazane busebenza ukuthola nokugcina i-gasket. Ngokomthetho izinguqulo 2 ziyatholakala; i-M&F Flanges Encane kanye ne-M&F Flanges Enkulu. Ukubhekana kwangokwezifiso kowesilisa nowesifazane kuvame ukutholakala kugobolondo le-Heat Exchanger ukuze kushaneli futhi kukhave ama-flange.

T - Ubuso Bolimi

Ubuso be-G-Groove

Ubuso be-Tongue kanye ne-Groove balawa ma-flange kufanele bufaniswe. Ubuso obunye be-flange bunendandatho ephakanyisiwe (Ulimi) efakwe ebusweni be-flange kuyilapho i-flange yokukhwelana inokucindezeleka okufanayo (I-Groove) efakwe ebusweni bayo.

Ukubhekana kolimi-ne-groove kulinganiselwe kuzo zombili izinhlobo ezinkulu nezincane. Zihluke kowesilisa nowesifazane ngokuthi ama-diameters angaphakathi olimi-ne-groove awadluli kusisekelo se-flange, ngaleyo ndlela agcine i-gasket kububanzi bayo bangaphakathi nangaphandle. Lezi zivame ukutholakala kumakhava epompo kanye namabhonethi eValve.

Amajoyinti olimi-ne-groove nawo anenzuzo ngokuthi ayaziqondanisa futhi asebenze njengendawo yokugcina izinto ezinamathelayo. Ijoyinti yesikhafu igcina i-axis yokulayisha ihambisana nejoyinti futhi ayidingi ukusebenza kwemishini enkulu.

Ubuso obujwayelekile be-flange obufana ne-RTJ, i-TandG ne-FandM angeke buhlanganiswe ndawonye. Isizathu salokhu ukuthi izindawo zokuxhumana azifani futhi akukho gasket enohlobo olulodwa ngakolunye uhlangothi nolunye uhlobo ngakolunye uhlangothi.

I-RTJ(RJ) -Ubuso Obuhlangene Bendandatho

Ama-Flange Okuhlanganiswa Kohlobo Lwendandatho ngokuvamile asetshenziswa kungcindezi ephezulu (Ikilasi 600 nesilinganiso esiphezulu) kanye/noma amasevisi okushisa aphezulu angaphezu kuka-800°F (427°C). Banemifantu esike ebusweni babo okuyinto steel ring gaskets. Ama-flanges ayavala lapho amabhawodi aqinisiwe acindezela i-gasket phakathi kwama-flanges angene emiseleni, elimaza (noma i-Coining) i-gasket ukuze yenze ukuthintana okuseduze ngaphakathi kwemigodi, okwenza insimbi ibe uphawu lwensimbi.

I-RTJ flange ingaba nobuso obuphakanyisiwe obunomugqa oyindandatho ofakwe kuwo. Lobu buso obuphakanyisiwe abusebenzi njengengxenye yezindlela zokuvala uphawu. Kumaflange e-RTJ avala ngama-ring gaskets, ubuso obuphakanyisiwe bama-flange axhunyiwe futhi aqinisiwe bungase buthintane. Kulokhu i-gasket ecindezelwe ngeke ithwale umthwalo owengeziwe ngaphezu kwe-bolt tension, ukudlidliza nokunyakaza akukwazi ukuqhubeka nokuchoboza i-gasket futhi kunciphise ukungezwani kokuxhuma.
