Ubuso be-Flange

Buyini ubuso be-Flange?

Izinhlobo ezahlukene zobuso be-flange zisetshenziswa njengendawo yokuxhumana ukuze kuhlaliswe impahla ye-gasket yokuvala. I-ASME B16.5 kanye ne-B16.47 ichaza izinhlobo ezahlukene zokubhekelwa kwe-flange, okuhlanganisa ubuso obuphakanyisiwe, ubuso obukhulu beduna nensikazi obunobukhulu obufanayo ukuze bunikeze indawo yokuxhumana enkulu uma kuqhathaniswa.

Amanye ama-flange faces ambozwe yilawa mazinga ahlanganisa ama-faces amakhulu namancane amancane ne-groove, kanye nelunga eliyindandatho elibheke ngqo ohlotsheni lwensimbi oluhlangene lwe-gaskets.

Ubuso Obuphakanyisiwe (RF)

I-Raised Face flange iwuhlobo oluvame kakhulu olusetshenziswa ekucubunguleni izinhlelo zezitshalo, 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).

Ubude bobuso obuphakanyisiwe

Ezilinganisweni zobude H no-B zazo zonke izilinganiso ezichaziwe zama-flange kule webhusayithi, ngaphandle kwe-Lap Joint flange, kubalulekile ukuqonda nokukhumbula okulandelayo:

Kumakilasi okucindezela okungu-150 no-300, ukuphakama kobuso obuphakanyisiwe cishe ku-1.6 mm (1/16 intshi). Kulezi zigaba ezimbili zengcindezi, cishe bonke abahlinzeki bama-flanges, babonisa kukhathalogi yabo noma incwajana, ubukhulu H no-B kuhlanganisa nobude bobuso obuphakanyisiwe. ((Umdwebo 1))

Emakilasini okucindezela 400, 600, 900, 1500 kanye no-2500, ukuphakama kobuso obuphakanyisiwe cishe ku-6.4 mm (1/4 intshi). Kulezi zigaba zengcindezi, abahlinzeki abaningi babonisa ubukhulu H no-B ngaphandle kobude bobuso obuphakanyisiwe. (Umdwebo 2)

Ubuso Obucaba (FF)

I-Flat Face flange ine-gasket surface endizeni efanayo nobuso bendilinga ebophayo. Izinhlelo zokusebenza ezisebenzisa ama-flange obuso obuyisicaba ngokuvamile yilawo lapho i-flange yokukhwelana noma i-flanged fitting yenziwe ngokusakazwa.

Ama-flange obuso obuyisicaba akumele abhawushwe ku-flange yobuso obuphakanyisiwe. I-ASME B31.1 ithi uma uxhuma amaflange ensimbi obuso obuyisicaba namaflange ensimbi ye-carbon, ubuso obuphakanyisiwe ku-carbon steel flange kufanele bukhishwe, futhi kudingeka i-gasket yobuso obugcwele. Lokhu okokugcina i-flange yensimbi ezacile, encanyana ukuthi ingaphumi esikhaleni esibangelwa ubuso obuphakanyisiwe be-carbon steel flange.

I-Ring-Type Joint (RTJ)

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.

Uhlobo lwe-Ring Joint gaskets

I-Ring Type Joint gaskets ayizindandatho zokuvala zensimbi, ezifanele ukusetshenziswa kwengcindezi ephezulu kanye nezinga lokushisa eliphezulu. Zihlala zisetshenziselwa ama-flange akhethekile, ahambisanayo aqinisekisa ukubekwa uphawu okuhle, okuthembekile ngokukhetha okulungile kwamaphrofayili nezinto ezibonakalayo.

I-Ring Type Joint gaskets iklanyelwe ukuvala "ngokuxhumana komugqa wokuqala" noma isenzo sokuhlanganisa phakathi kwe-flange yokukhwelana ne-gasket. Ngokufaka ingcindezi kusixhumi esibonakalayo sophawu ngokusebenzisa amandla ebhawodi, insimbi “ethambile” ye-gasket igelezela esakhiweni se-microfine sezinto eziqinile ze-flange, futhi idale uphawu oluqinile futhi olusebenza kahle.

Uhlobo olusetshenziswa kakhulu yisitayelaRiringi ekhiqizwa ngokuhambisana ne-ASME B16.20 esetshenziswa namaflange e-ASME B16.5, isigaba 150 kuya ku-2500. Amalunga ohlobo lwendandatho 'R' esitayela akhiqizwa kukho kokubili ukumiswa okusaqanda kanye ne-octagonal.

II-Octagonaliringi inamandla okuvalwa okuphezulu kune-oval futhi ingaba i-gasket ethandwayo. Kodwa-ke, i-oval cross section kuphela engasetshenziswa ohlotsheni oludala lwe-groove engezansi. Idizayini entsha yegroove ephansi eyisicaba izokwamukela ingxenye eyisiyingi noma eyi-octagonal cross.

Amajoyinti ohlobo lwendandatho yesitayela sika-R aklanyelwe ukuvala ingcindezi efika ku-6,250 psi ngokuvumelana nezilinganiso zokucindezela ze-ASME B16.5 futhi kufika ku-5,000 psi.

IRXuhlobo lufanele izingcindezi ezifika ku-700 bar. Le RTJ iyakwazi ukuzivala yona. Izindawo zokuvala zangaphandle zenza ukuthintana kokuqala nama-flange. Ukucindezela kwesistimu ephezulu kubangela ukucindezela okuphezulu kwendawo. Uhlobo lwe-RX luyakwazi ukushintshaniswa namamodeli we-R ajwayelekile.

IBXuhlobo lufanele izingcindezi eziphezulu kakhulu ezifika ku-1500 bar. Lokhu kuhlanganiswa kweringi akushintsheki nezinye izinhlobo, futhi ifanelekela kuphela uhlobo lwe-API BX flanges nemisele.

Indawo yokuvala emigedeni ehlangene eyindandatho kufanele iqedwe kahle ibe ngama-Microinches angu-63 futhi ingabi nama-ridges angafaneleki, amathuluzi noma izimpawu zokuxoxa. Bavala ngokuthintana nomugqa wokuqala noma isenzo sokushada njengoba kusetshenziswa amandla okucindezela. Ukuqina kwendandatho kufanele kuhlale kungaphansi kokuqina kwama-flanges.

Ukukhetha impahla

Ithebula elingezansi libonisa izinto ezisetshenziswa kakhulu amajoyinti ohlobo lwendandatho.

I-Tongue-and-Groove (T&G)

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 komshini omkhulu.

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.

Owesilisa nowesifazane (M&F)

Ngalolu hlobo ama-flanges 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.

Ubuhle nokubi kobuso be-T&G ne-M&F flange

Izinzuzo
Izakhiwo zokuvala ezingcono, indawo enembe kakhudlwana kanye nokucindezelwa okunembile kwempahla yokuvala, ukusetshenziswa kokunye, ukuvala okulungele kakhudlwana kanye nezinto zokuvala ezenziwe nge-spezialized (O-rings).

Ukubi
Ukutholakala kwezentengiso nezindleko. Ubuso obujwayelekile obuphakanyisiwe buvame kakhulu futhi bulungele ukutholakala kokubili mayelana nama-Valves, ama-flange kanye nezinto zokuvala. Okunye okuyinkimbinkimbi ukuthi eminye imithetho eqinile kufanele isetshenziswe ekwakhiweni kwamapayipi. Ingabe uyala ama-Valves ukuthi abe ngowesifazane aphethe izinhlangothi zombili, noma ohlangothini olulodwa mhlawumbe, lapho ukhomba zonke iziphetho zesilisa endleleni yokugeleza, noma yini. Okufanayo kusebenza kunoma yikuphi ukuxhumana okuhlangene / komkhumbi okune-flanged Yebo.
