Insimbi engenasici iyinsimbi esetshenziswa kakhulu yensimbi engenasici kanye nensimbi engasho lutho. Kusebenza kwimishini yokukhiqiza ukudla, imishini yamakhemikhali ye-Xitong, amandla enuzi, njll.

I-Flange yizingxenye ezixhumanise amaphayipha amabili, ukuxhumana kwe-flange kuchazwa yi-flange, i-gasket kanye ne-bolt ezintathu zixhumeke njengeqembu lesakhiwo esihlanganisiwe sokwenza uphawu okuhlangene. I-gasket yengezwa phakathi kwama-flanges amabili bese iboshwe ngama-bolts. I-Flange ye-Flange ehlukile, ubukhulu bahlukile, futhi ama-bolts abawahlukile ahlukile, lapho i-pump ne-valve xhuma ngepayipi le-flange, lolu hlobo lwezinto ezivuthiwe nalo lungenziwa nge-flange ne-flange pay, njengokuxhumana phakathi kwe-flange nephampu yamanzi, akunjalo I-Inapposite ukubiza ipompo yamanzi njengezingxenye zohlobo lwe-flange, kepha isihlobo esincane esincane, ingabizwa njengezingxenye zohlobo lwe-flange.

Amapayipi Flangele axhumeka amapayipi nezinto ohlelweni lwamapayipi ngokusebenzisa ukuxhumana okubilisiwe kanye nama-gaskets. Ama-flanges asetshenziswa kakhulu yi-butt welding flanges, ama-flanges ashelelayo, ama-flanges ayimpumputhe, ama-flanges we-welding we-socker, ama-flange ahlanganisiwe kanye nama-flanges ahlanganisiwe (ama-flanges e-LTJ). Lolu hlobo lokuxhumeka kumaphayili we-Piales lusiza ukungafani nokunqanyulwa kwensiza kanye nokulungiswa njalo. Ukucaciswa okuvame kakhulu ngensimbi ye-carbon kanye nama-flanges ensimbi angenasici yi-ANSI B16.5 \ ASME B16.5.

I-Flange eyimpumputhe iyi-flange eqinile ngaphandle kwezimbobo noma izimbobo ezihlanganisiwe ezisetshenziselwa ukuvala ukuphela kwepayipi, efanelekile, i-valve noma imishini. Ama-flanges ayimpumputhe nawo asetshenziswa emishini yokuhlola ingcindezi. Ama-Flanges ayimpumputhe ayatholakala ngezinhlobo ezimbili: i-convex nefulethi.

Nge-dectility ephezulu kanye namandla omthelela, i-SMO 254 iyindlela eshibhile enye indlela ephezulu ye-nickel kanye nama-tanium alloys kwezinye izinhlelo.

I-flange iyindandatho yensimbi (eyakhiwe, enqunywe kusuka epuletini, noma i-rolled) yakhelwe ukuxhuma izingxenye zepayipi, noma ukujoyina ipayipi kumhlangano wengcindezi, i-valve, iphampu noma omunye umhlangano ovusiwe ovusiwe. Ama-Flanges ahlanganiswe komunye nomunye ngama-bolts, futhi ohlelweni lwamapayipi ngokushiswa noma ngomcucu (noma okuxekethile lapho kusetshenziswa izimbumbulu). I-Finanless yensimbi filange eyenziwe lula njenge-SS Flange, isho ama-flanges enza ngensimbi engenacala. Amazinga ajwayelekile wezinto ezibonakalayo namamaki yi-ASTM A182 Ibanga F304 \ l ne-F316 \ l, libe ngu-2500 njll.

I-254 SMO iyinsimbi ephakeme ye-auntenitic auntenitic adlenled ukuze isetshenziswe ku-chloride-bearing media noma izinhlelo zasolwandle. I-254 SMO ibonakala ngokuqukethwe kwayo okuphezulu kwe-chromium, lokhu kuqhutshwa futhi okuqukethwe kwayo kwe-molybdenum kanye ne-nitrogen okunikeza ukumelana okuhle kakhulu kwe-smo Njengoba la mathangi okugcina kawoyela atholakala kwi-Arabian Gulf (izimo zesawoti) ukusetshenziswa kwalokhu kusetshenziswa kwakuyikhambi elifanele lemvelo. Ngaphezu kwalokhu, ukuhlanganiswa kwama-flanges nakho kukhethwe ngokukhethekile ngenxa yezimpawu zayo zokuvikela.

I-Slip on Flange empeleni indandatho ebekwe ngokuphela kwepayipi, ngobuso obuhle busuka ekugcineni kwepayipi ngebanga elanele ukufaka i-waad engaphakathi. I-od yokushelela ku-flange nayo ifakwe ohlangothini lwangemuva lwe-flange.

Ama-Flango ensimbi ahlinzeka ngokufinyelela okulula kokuhlanza, ukuhlola noma ukuguqulwa. Imvamisa ziza ngezimo eziyindilinga kepha nazo zingafika ngezindlela zesikwele nezinxantathu. Ama-flanges ahlanganiswe komunye nomunye ngokubopha futhi ajoyine ohlelweni lwamapayipi ngokushiswa noma ethangothini futhi aklanyelwe izilinganiso ezithile zengcindezelo; I-150LB, 300LB, 400LB, 600LB, 900LB, 1500LB no-2500lb.

Ama-flanges enziwe ngensimbi engama-310s acrenless, okuyinto evimbela i-autenitant anloy engenacala. I-310s i-filange engagqwali inamazinga aphezulu we-chromium (24-26%) kanye ne-nickel (19-22%) ukuhlinzeka ngokumelana nokuqina okuphezulu kanye namandla okushisa aphezulu.

Ifaka insimbi engama-304 engenasici ukuze imelana nokugqwala okuhle kakhulu, le llainger evunyiwe ye-weldi tek flange ingafakwa ohlelweni nge-clurceferance ye-wald entanyeni. Indawo ye-welded ingahlolwa kalula yi-radiography. Ipayipi elifanisiwe ne-Flange Brore inciphisa isiyaluyalu nokuguguleka ngaphakathi kwepayipi. I-Flange ihle kakhulu ukuze isetshenziswe kuzinhlelo zakho ezibucayi futhi ilungele ukusetshenziswa ngomoya, amanzi, uwoyela, igesi yemvelo kanye nomusi.

Okuqukethwe kwe-nickel ngensimbi engenasici ama-uns ama-flanges angenasici ama-S30400 Blind

I-Flanged Joint yakhiwa okuhlukile okuhlukile futhi okuzimele yize izingxenye ezihlangene; amafuvu, ama-gaskets, kanye ne-bolting; aqoqwe ngelinye ithonya, i-fitter. Izilawuli ezikhethekile ziyadingeka ekukhetheni nasekusetshenzisweni kwazo zonke izinto ezikhona ukuthola okuhlanganisiwe, okunokuqina okuvuzayo okwamukelekayo.

Ama-flice wensimbi engagqwali Ama-flangeni ancishisiwe wensimbi asiza ukuxhuma osayizi ababili abahlukahlukene bepayipi. I-316 ama-flanges e-stainless ensimbi asetshenziselwa ukuxhuma amapayipi osayizi abahlukahlukene. Kuthiwa futhi ebangeni lasolwandle.

I-ASME B36.19M ingukucaciswa okujwayelekile kwamapayipi ensimbi angenasici, acacisa ubukhulu, ukubekezelelana kanye nezidingo zokukhiqiza amapayipi afakwe emthungo.

I-254 SMO iyinsimbi ephakeme ye-auntenitic auntenitic adlenled ukuze isetshenziswe ku-chloride-bearing media noma izinhlelo zasolwandle. I-254 SMO ibonakala ngokuqukethwe kwayo okuphezulu kwe-chromium, lokhu kuqhutshwa futhi okuqukethwe kwayo kwe-molybdenum kanye ne-nitrogen okunikeza ukumelana okuhle kakhulu kwe-smo Njengoba la mathangi okugcina kawoyela atholakala kwi-Arabian Gulf (izimo zesawoti) ukusetshenziswa kwalokhu kusetshenziswa kwakuyikhambi elifanele lemvelo. Ngaphezu kwalokhu, ukuhlanganiswa kwama-flanges nakho kukhethwe ngokukhethekile ngenxa yezimpawu zayo zokuvikela.

Ukunciphisa ama-flanges kufanelekile ukuguqula osayizi wepayipi, kepha akufanele kusetshenziswe uma kushintshwa kungazelelwe kuzokwakha isiyaluyalu esingafuneki, njengokuxhunywa kwepompo. Ukunciphisa ama-flanges aqukethe i-flange yobubanzi obuthile ngezimbobo zamadayimane ahlukene futhi amancane. Ngokungeziwe kusayizi we-bore ne-hub, i-flange izoba nobukhulu ngosayizi omkhulu wepayipi.

Ifana nekhabhoni ephansi kakhulu equkethe ama-alloys wensimbi engenasici angama-316l atholakala kalula ukuthi ahlukunyezwe ngokugqwala komoya.

Kubuye kube yindlela ebiza kakhulu yokubiza ama-alloys angabizi kakhulu, njengohlobo 316, olungenawo amandla noma ukumelana nokugqwala okudingekayo ukunciphisa izindleko zokujikeleza kwempilo kuzicelo ezithile.

Lokhu kuhlanganiswa kwenza insimbi engagqwali engama-304 Flanges inamandla futhi inokumelana okuhle kokugqwala. Lawa ma-flanges anamandla amancane wesivuno angama-205MPA kanye namandla ashubile angu-515MPA. Leli banga linezinhlobo ezahlukene zama-flanges. Ama-flanges angama-SS 304 izimpumputhe asetshenziselwa ukuvala noma ukuvala amapayipi.

Ukunciphisa ama-flanges kufanelekile ukuguqula osayizi wepayipi, kepha akufanele kusetshenziswe uma kushintshwa kungazelelwe kuzokwakha isiyaluyalu esingafuneki, njengokuxhunywa kwepompo. Ukunciphisa ama-flanges aqukethe i-flange yobubanzi obuthile ngezimbobo zamadayimane ahlukene futhi amancane. Ngokungeziwe kusayizi we-bore ne-hub, i-flange izoba nobukhulu ngosayizi omkhulu wepayipi.

I-Flange iyisigaxa esinqunyelwe, i-lip noma i-rim, kungaba yangaphandle noma yangaphakathi, esebenza ukukhulisa amandla (njenge-flange yogongolo lwensimbi efana ne-i-beam noma i-t-beam); Ukuthambekela okulula noma ngokuzinza futhi uqondise ukunyakaza komshini noma izingxenye zawo (njenge-flange yangaphakathi yemoto yesitimela noma isondo le-tram, eligcina amasondo asuka ojabha). Igama elithi "i-flange" lisetshenziselwa futhi uhlobo lwethuluzi olusetshenziselwa ukwakha ama-flanges.

I-321h yensimbi engenasici ingukuguqulwa kwe-321 yensimbi flange ngokuqukethwe okuphezulu kwekhabhoni, ukuhlinzeka ngamandla aphezulu okushisa aphezulu.

Lapho kunikezwa ukwelashwa kokushisa, kubalwa ukunqunyelwa kwesigaba se-sigma. I-SS 310s I-alloy ephansi yekhabhoni isetshenziswa ngenxa yokunetha kwayo kalula.

Imigoqo yensimbi nezinduku
Ama-Flanges ancishisiwe asetshenziselwa ukunciphisa ububanzi bamapayipi endaweni yokuxhuma. I-Flange empeleni iyinto eyindilinga enezindebe noma ikholaji kuyo, esetshenziselwa ukufukula nokusebenza kwe-welding. Lezi zinto ezifana nezinsimbi ezingezinciphisi ezingenasici zilusizo kakhulu ekusetshenzisweni kwezinga lokucindezela lapho ukuxhumana kwamapayipi amabili kufanele kube khona ngokuphelele. Ukunciphisa i-flange kubalulekile ngoba kunciphisa ububanzi bepayipi futhi kusekela ukugcinwa kwengcindezi nokugeleza koketshezi kuhlelo lokusebenza.

Ngokusho kuka-Asme B16.5, i-HUB ye-Butt Welding Flange ingahlukaniswa ngengxenye ye-tapered kanye nengxenye eqondile.
