Uma uthi 'i-stainless steel flange', abantu abaningi abathengayo bacabanga ngento ethengiswayo. Hlola izinga le-ASTM A182, fanisa isilinganiso sokucindezela, beka i-oda. Kwenziwe. Kodwa yilapho ukunqanyulwa kokuqala kwenzeka khona. Ishidi elicacisiwe likutshela ukuthi kufanele libe yini, hhayi ukuthi libe yini ngemva komshini, noma okubi nakakhulu, ngemva kokuba lisebenze izinyanga eziyisithupha endaweni egcwele i-chloride. Ukuqonda kwangempela kuqala lapho usubone i-316L flange, okucatshangwa ukuthi iphelele ephepheni, ithuthukisa ukugqwala kwengcindezi emigodini yebhawudo ngoba isitolo somshini sisebenzisa amathuluzi afanayo esiwasebenzisele i-carbon steel, sethula ukungcola. Leso igebe okungekho PDF elingasivala.
Inganekwane Ebalulekile kanye Neqiniso Lomshini
Asikhulume amamaki. 304, 316, 316L, 904L, Duplex 2205. Wonke umuntu uphonsa lezi zinombolo nxazonke. Umgodi ojwayelekile uthatha ukuthi 316 'ingcono' nje kune-304. Imelana nokugqwala, yebo, kodwa futhi iwubuqili kakhulu emshinini. Isebenza-iqina njengohlanya. Ngike ngabona omashini abangenalwazi becekela phansi inqwaba yama-forged insimbi engagqwali flange izikhala ngoba basebenzise izinga lokuphakela elingalungile, bakha ungqimba olungaphezulu olwenze ukuba ubuso obulandelayo bezihlalo be-gasket bungenzeki. Ingxenye yayiphelele, kodwa ingasebenzi kahle.
Kulapho ukusebenzisana ne-Foundry ephinde iphathe imishini yasendlini, njenge-QSY over at tsngtaocnc.com, kwenza umehluko obonakalayo. Sekuphele amashumi amathathu eminyaka bekulokhu, ngakho-ke inqubo yabo ayifakwanga. Umfana ophethe i-CNC uyazi ukwakheka kokusanhlamvu okuvela ekutshalweni kwezimali kwakhe noma inqubo yokubumba igobolondo. Uyazi ukuthi ku-flange yokucindezela okuphezulu okubalulekile, ungase udinge ukulungisa ukulandelana kwemishini ye-Duplex alloy ngokumelene ne-316L evamile ukuze ugcine ibhalansi yesigaba kanye nezakhiwo zokugqwala. Lolo ulwazi oluyimfihlo ongalutholi esitolo semisebenzi esivele sithenge isitoko sebha eluhlaza.
Ngikhumbula iphrojekthi yolayini wokupholisa amanzi olwandle. Ukucaciswa kwakuyi-ASTM A182 F316L. Sithole ama-flange kumhlinzeki wejenerikhi. Baphumelele wonke amasheke e-MTR. Nokho, kungakapheli unyaka, saba nokubhoboza ubuso obuphakanyisiwe. Ukuhlaziywa kokwehluleka kukhomba ekufakweni okuncane kakhulu—imikhondo yensimbi yamahhala—okungenzeka ishumekwe phakathi nokupholisha kokugcina. Inqubo yomphakeli ayizange ilawulwe ukungcoliswa okuphambene. Kwakuyisifundo esibuhlungu ukuthi uhlu lozalo lwezinto ezibonakalayo luhle kuphela njengenqubo yokugcina eyadlula kuyo.
Ubuqotho Bokuxhuma: KuMininingwane
Ubuso be-flange buphelile. RF, FF, RTJ. Izinga le-ASME B16.5 likunikeza ububanzi buka-Ra (isilinganiso sobunzima) ebusweni obuphakanyisiwe, ngokuvamile obungu-125 kuya ku-250 μin Ra. Kodwa ukushaya inombolo akuwona umgomo. Umgomo ukwakha indawo evalekayo enganyongo ngaphansi kwetorque yebhawudi futhi ivumela i-gasket ukuthi igeleze kahle. Ubushelelezi kakhulu, futhi usengozini yokushelela; rough kakhulu, futhi uhlafuna ama-gaskets athambile. Kuye kwadingeka ngisebenzise i-profilometer ephathekayo esizeni ukuze ngibonise iklayenti ukuthi inkinga yalo yokuvuza isukela ebusweni bokuqedela isibuko obungaphandle kokucaciswa, hhayi ku-gasket yethu.
Ukuqondanisa kwembobo ye-bolt. Kuzwakala kuyinto engasho lutho, akunjalo? Kodwa ngobubanzi obukhulu, yithi i-Class 150 yamayintshi angu-24 insimbi engagqwali flange, ukunwetshwa okushisayo nokubekezelela umshini wokupakisha kungakuluma. Uma izimbobo zebhawodi zibhojwa nge-flange elele phansi, kodwa ishiselwe ekugijimeni kwepayipi eliqondile, isisindo singabangela ukuhlanekezela kancane. Ugcina usunamabhawudi angeke angene ngokukhululeka. Ukulungisa? Kwesinye isikhathi icacisa ukuthi izimbobo zamabholithi ziphelile ngemuva kokuthi iphedi yokushisela isinamathiselwe, noma okungenani kuqinisekiswe ukuthi umenzi we-fagathi usebenzisa ijigi elingisa umumo ofakiwe. Yilezi zilawuli zenqubo encane ezihlukanisa ukufakwa okushelelayo nephupho elibi lokusebenza kabusha kwenkambu.
Bese kuba nenkulumo-mpikiswano ye-weld neck ne-slip-on. Ngemithwalo eguqukayo noma amazinga okushisa aphezulu, i-weld neck iyinkosi. I-tapered hub transition isabalalisa ingcindezi. Kodwa ngibone ama-slip-on flange acaciswe ukonga izindleko kumugqa we-steam, kuphela ukushiselwa kwe-fillet ku-crack yehabhu-to-pipe junction ukusuka ekushicileleni okushisayo. Ukongiwa kwezindleko kwaqedwa izikhathi eziyishumi ngokuvala nokulungiswa. Ukukhetha akukhona nje ukukala ingcindezi; imayelana nobuntu besistimu—indlela eshisa ngayo, iphola, idlidliza.
Ukusakaza vs. Forging: Ukukhetha Kokuqukethwe
Okuzenzakalelayo kwemboni yesevisi ebalulekile kungama-flange omgunyathi. Ukugeleza okusanhlamvu okungcono, amandla aphakeme, ubuthakathaka obungase bube buncane. Kuyisinqumo esiphephile. Kodwa ekucushweni okuyinkimbinkimbi, kwevolumu ephansi, noma usayizi omkhulu, ukusakaza kwekhwalithi ephezulu kuyindlela esebenzayo futhi evame ukonga kakhulu. Ukhiye 'yikhwalithi ephezulu'. Ukubunjwa kwegobolondo okuvela kuchwepheshe onjengaye I-Qingdao Qiangsenyuan Technology Co., Ltd.(QSY) ingafinyelela ukuminyana kanye nezakhiwo zemishini ezihlangabezana namazinga omgunyathi wezinhlelo zokusebenza eziningi, ikakhulukazi uma ubhekene nama-alloys asuselwa ku-nickel angaphandle okuyiphupho elibi ukuzenzela ngamanani amancane.
Sisebenzise ama-flange angenasici e-investment-cast 310S ekusetshenzisweni kwesithando sokushisa okuphezulu esikhathini eside. Ijiyomethri yayinodebe oluyisivikelo sokushisa olubalulekile obekungaba lubiza kakhulu umshini osuka kufogi. Ukulingisa, okulandelwa umshini we-CNC onembile wezindawo zokuvala nezimbobo zamabhawodi, bekulungile. Isifundo lapha akukona ukulahla ukusakaza ngokuqondile. Kumayelana nokwazi ikhono le-Foundry. Umlando wabo weminyaka engama-30 ekubunjweni kwamagobolondo kanye nokutshala imali, njengoba kuphawulwe esizeni sabo, uphakamisa ukuthi baxazulule izinkinga zokuncipha kanye ne-porosity enikeza ukulingwa igama elibi.
Lapho ngisazogcizelela khona ukuthi ngifoge ngokulayisha umjikelezo onzima. Cabanga ngezigubhu ezikhipha i-compressor noma izihloko zephampu eziphindaphinda ingcindezi. I-isotropy yengxenye engumgunyathi inikeza umkhawulo wokuphepha okunzima ukuphikisana nawo. Kodwa noma kunjalo, i-forging idinga ukwelashwa okufanele kokushisa. I-F51 Duplex flange engafakiwe isixazululo futhi yacishwa ngendlela efanele izoba nokumelana nokugqwala, kungakhathaliseki ukuthi yakhiwe kanjani.
I-Pragmatism ye-Supply Chain
Izikhathi zokuhola. Wonke umuntu ufuna yonke into izolo. I-flange engenasici eyakhiwe emshinini omkhulu ingaba nesikhathi sokuhola samaviki angu-20. Kulapho umkhiqizi oguquguqukayo onezinqubo ezihlanganisiwe anganqamulela khona. Uma benekhono lokukhiqiza umzimba we-flange ngokusakaza bese uwumshini wonke ngaphansi kophahla olulodwa, njengoba kwenza i-QSY, kwesinye isikhathi ungashefa amasonto ngaphandle kweshejuli. Akukhona ukusika amakhona; imayelana nokuhlanganiswa kwenqubo okuqeda izikhathi zomugqa phakathi kwabathengisi abahlukene.
Ukulandeleka akuxoxiswana ngakho. Izinombolo zokushisa, imibiko ye-PMI (Positive Material Identification), izitifiketi zokuhlola. Kodwa ngaphandle kwamaphepha, kukhona ukulandeleka ngokomzimba. Ngiyabazisa abahlinzeki abathi, empeleni, bacime kancane ibanga lezinto ezibonakalayo nenombolo yokushisa kuhabhu ye-flange. Kuyinto encane, kodwa uma wenza ucwaningo lwamabhuku eminyakeni eyishumi kamuva, lelo phawu elihlala njalo libiza ngaphezu kwe-PDF egcwalisiwe. Kubonisa isimo sengqondo esiqonda umjikelezo wokuphila womkhiqizo.
Ekugcineni, 'ukulingana' nomenzi. Ithumela umshini ophelele, onembayo insimbi engagqwali flange kumkhiqizi we-pipe spool oyiqinisa ku-vise yensimbi ye-carbon noma osebenzisa isondo eliqhumayo ebusweni iresiphi yobuhlungu benhliziyo. Ngezinye izikhathi, isevisi ebaluleke kakhulu umphakeli we-flange ayinikezayo imfundo eyisisekelo—izingxenye zokuthumela ezinezingubo zokuzivikela ebusweni, kuhlanganise neziyalezo zokuphatha, ngisho nokunikeza ukuqeqeshwa endaweni. Iguqula okwenziwayo kube ubambiswano oluqinisekisa ukuthi ingxenye isebenza ngendlela edizayinwe ngayo.
Ukusonga: Izinto Ezingabonakali
Ngakho, uthengani ngempela? Awuthengi i-hunk yensimbi engagqwali emile. Uthenga ubuqotho bohlangothi, ukungaguquguquki kwe-metallurgical, isimo esingaphezulu, futhi ekugcineni, isiqinisekiso sobuqotho bokuxhumeka ngaphansi kwezimo ezithile zesevisi. Umehluko wentengo phakathi kwabathengisi uvame ukubilisa ukuthi singakanani isiqiniseko esibhakwe kuleyo ntengo. Inketho eshibhile ayikaze inciphise izinto; kungenzeka banqamule izilawuli zenqubo, izinyathelo zokuhlola, noma ukuphatha.
Uma sibheka emuva ekuhlulekeni, akuvamile ukuba kube ngenxa yokubalwa kabi kwengcindezi. Kungenxa yokunqwabelana kokuchezuka okuncane: ukwakheka kancane kwekhemikhali okwehlisa ukumelana ne-CREP, i-machining burr esika i-gasket, indawo engcolile eqala ukugoba. Ukulawula lokhu kuchezuka yilokho okukhokhelayo.
Kungibuyisela kubakhiqizi abadidiyelwe. Lapho ibhizinisi elifanayo lilawula inqubo kusukela ekubumbeni noma ekusakazeni kuye ekudluleni kokugcina kwe-CNC, kunomugqa oqondile wokuziphendulela. Iluphu yempendulo ifushane. Uma inkinga yomshini ilandelelwa emuva kokudidayo, leso sifundo sibuyela ngqo ku-Foundry. Lolo uhlobo lwesistimu yekhwalithi evaliwe, okuthi, ngaphezu kweminyaka engama-30, yakhe ubungcweti bokwenza uhlelo olulula. insimbi engagqwali flange ngokwethembekile uneventful. Futhi kuleli bhizinisi, ukungalingani kuwukuncoma okuphezulu kakhulu.
