Ama-Fasteners e-Duplex

Njengoba izilinganiso eziphakeme zengcindezelo zidinga kuphela lolu hlobo lokuxhumeka lwe-flange, ama-flange we-butt weld ajwayele ukwenziwa ngobuso obuhlangene bendandatho (eyaziwa nangobuso be-RTJ. Le ndawo ebopha uphawu ivumela ukuthi i-gasket yensimbi ichotshozwe phakathi kwama-grooves ama-flanges amabili okuxhumanisa ukudala uxhumano oluhle kakhulu lwe-beldel assert emhlanganweni wepayipi ocindezelwe. Izintamo ze-RTJ Weld ezinokuxhunyaniswa kwensimbi yensimbi kungukukhetha okuyisisekelo kwezicelo ezibucayi.

Izinhlobo zama-flanges zifaka amaflethi akhiwa amaflethi, ama-SS 304 ama-flange afakiwe kanye nama-flate amafulethi. Lezi zinhlobo ezahlukahlukene zisetshenziswa ezinhlotsheni ezahlukahlukene zezicelo ezinjengamafutha negesi, i-petrochemical, uphethiloli, ukumba uwoyela osogwini, imigqa yamanzi yasekhaya, amaphepha kanye nezimboni ze-pulp, nokuningi.

Ama-Flanges amade we-butt weld, owaziwa nangokuthi ama-nozzle flanges noma "amafulegi ande" amafulegi, enzelwe izimboni zokudonswa kwethangi. Zivame ukwenziwa esiqeshini esisodwa futhi zenzelwe ukufaka esikhundleni senhlamvu evamile ye-weld nepayipi. Ukuntuleka kokuxhumeka kwe-welded okudingekayo kuyinto echazayo yalesi sitayela se-flange.

Azikho izikhala noma ama-grooves ezingaholela ekugcekeni kwe-crevice. Izintamo ezi-conical zaziwa nangokuthi "izintambo ze-nozzle" noma ezivame kakhulu "ama-hubs aphezulu". Yize ama-flanges abizayo, ama-weld we-butt ama-flanges aklanyelwe amahle kakhulu we-butt weld ngoba i-tapered tapered hub ihlinzeka ngamandla amahle nokuphikiswa kwezinhlanzi.

I-Duplex Steel Material of Ex S31803 nayo iyasebenza. Ngaphezu kwensimbi engagqwali, ama-flange ama-weld wezempi atholakala kwezinye izinto ezifana ne-carbon alloys ne-nickel. Ama-flanges we-nickel alloy butt atholakala nge-contel 600 no-625, i-hastelloy C22, C276 nezinye izinto ezinjalo.

Ngokusho kuka-Asme B16.5, i-HUB ye-Butt Welding Flange ingahlukaniswa ngengxenye ye-tapered kanye nengxenye eqondile. Ubude obuqondile bungama-6mm, okuyinto efaniswe kahle namapayipi aseduze, okulungele ukufudumala. Ama-Flanges we-Butt Weld adilizwa ukufanisa ububanzi obungaphakathi kwepayipi eliseduze. I-Thinner udonga lwepayipi, likhudlwana umgodi nge-flange. Omkhulu udonga, omncane umgodi. Ngenxa yalokhu kuhlangana okufanayo, akunamikhawulo kwithrafikhi. Isiyaluyalu nokuguguleka kukhonjwe.

Uma kukhulunywa ngezinto zokwakha, ama-alsoy e-carbon ayizinto ezivamile zokwenza lawa mafuvu ngoba nawo ayamelana namazinga okushisa athe xaxa. Kuyatholakala e-ASTM A 181 ne-ASTM izinto eziyi-105. Ama-Flango atholakala kumabanga ahlukahlukene afana ne-ASME B16 47 'A' Shungechunge uchungechunge lokuhlangabezana nezidingo zamakhasimende nezimboni.

Ngaphezu kwentambo evamile ye-weld entanyeni, iTexas Flange inikezela ngokuxhumeka okuhlukahlukene kwe-nozzle ngobukhulu obuhlukahlukene odongeni. Lapho umkhumbi wakho wengcindezi ufuna ukuxhumana okuqinile kokuphuma futhi unganikeza ubukhulu bakho be-barrel oyifunayo, i-barrel eqinisiwe ye-flange ngesimo se-nozzle inketho. Sicela uxhumane nathi ngesicelo sakho esithile njengoba singakwazi ukuhambisa ama-nozzle Flangese kuwo wonke amabanga atholakalayo okutholakala kwezentengiso kufaka phakathi ikhabhoni, insimbi engenasici kanye ne-nickel alloys.

Ama-flanges we-RFWn (aphakanyisiwe ebusweni bentamo yamathambo) angenye yezindawo ezisetshenziswa kakhulu embonini yamapayipi. I-Hub yabo ende ye-tapered ifana nobukhulu bodonga (umgodi) wepayipi futhi kulula ukubona.

Isisekelo sentamo esixhuma esisekelweni se-flange siyindilinga kancane ukuze sinciphise ukuxhumana okuthe mpo phakathi kwezingxenye ezimbili ze-flange futhi ziqinisa umbono wokuqinisa isakhiwo esisodwa.

Ama-Flanges we-Butt Weld ayatholakala kuwo womabili akhulisiwe kanye nokucushwa kwefulethi. Ama-Flanges ajwayelekile kakhulu we-butt welld anezimbobo ezijwayelekile noma izimbobo ezisindayo ezengeziwe. I-SCH 120 noma i-SCH 160 HOLE FLICES, izinsimbi ezisindayo ezifana ne-600 # kuya ku-1500 #, nazo zivame kakhulu emafulethini e-butt weld. I-HT Pike ithengisa ububanzi be-butt weld flanges ku-a105, a105n, insimbi engagqwali, i-duplex kanye ne-super duplex steel kanye ne-nickel alloys.

Izimbobo ze-Weld Flange zidwetshwe ukufanisa i-ID yepayipi noma kufanelekile. Lokhu kudala ukuguqulwa okubushelelezi phakathi kwamafulethi entamo we-weld futhi kuvimbela isiphithiphithi entanyeni ye-weld. Ngakho-ke, kubalulekile ukucacisa uhlelo lwamapayipi lapho uthenga amaflethi we-butt weld. Ama-FLD we-Butt Weld afakwe ku-pipe ngepayipi eline-penette ephelele futhi anikeze ukusatshalaliswa kwengcindezi okuhle kakhulu ngentamo. Kuhlelo lokusebenza olubucayi, ama-welds nawo avame ukuhlolelwa.

Lezi zitayela ze-flange zaziwa ngokuthi "i-Hub Hub Weld Flanges" ngokusho kwesigatshana se-ASME B16.5 futhi zinikezwa imininingwane emincane kwiKhodi Ebusayo. Lokhu kungenxa yokuthi izintambo ezinde ze-weld zikhethwe ngesisekelo ngasinye sohlelo lokusebenza ngokuya ngezidingo ezithile zobunjiniyela bobunjiniyela bethangi noma umphangi wengcindezi. Ingcindezi yokusebenza, izinga lokushisa kanye ne-medium of the vessel zonke izinto ezisemqoka ekunqumeni ukuthi uluphi uhlobo lokuxhumeka kwe-flange ye-butt ye-butt

I-Stainless Steel 304 Ama-Flango asetshenziselwa ukujoyina amapayipi ndawonye. Ziyahlukahluka kusuka ekuqondeni kulokho wonke ama-flanges anokuvela kwangaphandle okunikeza isikhala esingeziwe sokuxhunywa njengokufudumeza noma ukubopha.

Ama-flanges amade abukeka njengamandla ajwayelekile we-butt weld kodwa abhekwa njengenwetshiwe. Imvamisa isetshenziswa njenge-nozzle yekholamu noma umgqomo. Ungase futhi ukhethe phakathi kweBalm Barrel Elinganayo kanye ne-LWN esindayo umphongolo, onezindonga eziwugqinsi nokwakhe.
