I-filange engenasici

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.

Izimpumputhe zingama-flanges ngaphandle kwesikhungo esinezindawo (umgodi noma ukuvula) futhi ziyatholakala kuzo zombili izitayela zobuso (ze-ff). Ngenkathi izinhlobo eziningi ze-flange zidala iphuzu lokuxhumeka elivumela ukugeleza koketshezi, igesi, noma umoya, ama-flanges ayimpumputhe asetshenziselwa ukuvala ukuphela kohlelo lwamapayipi futhi avikele ukugeleza. Ama-flanges ayimpumputhe angasetshenziswa lapho uhlola ingcindezi yepayipi, ukudala indawo yokufinyelela ohlelweni lwamapayipi, ukuze akwazi ukuvala uhlelo lwe-piping ngenkathi elungisa noma elungisa uphawu lwesikhathi eside ukuze unqamule uhlelo lwamapayipi.

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

Insimbi engagqwali 316 \ 16l flanges ingenziwa ngokushisa okushisayo noma ngokuphonsa. Ama-flate epuleti ayimpumputhe noma ashelelayo ngaphandle kwama-hubs angafakwa emnyani ngokuqondile epuletini. Ama-Flanges kufanele abe yisixazululo esiphathwe kungaphansi kuka-1900¡Ãf [1040¡Ãc] bese ucishwa emanzini abandayo noma enye indlela yokupholisa ngokushesha.

Iziphetho ezimfushane ziyatholakala ngohlobo lwe-a nohlobo B. Thayipha ama-EMPLOS ajwayelekile kakhulu. Ama-Flanges we-Lap afulethi kuphela. Abantu badida ama-flanges we-LAP ngama-flanges we-slip

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.

I-304 Insimbi Engagqwali iyi-carbon ephansi (0.08% max) yesisekelo 18-8 (eyaziwa nangokuthi 302). Uhlobo 302 luqukethe i-18% i-chromium ne-8% nickel. Uhlobo 304 luqine kancane kuno-302 ngenxa yokuqukethwe kwalo kwekhabhoni ephansi. Uhlobo 304 lusetshenziselwa izinhlelo zokusebenza ze-welding ngoba i-carbon ephansi ivumela ukuvezwa okuthile ku-carbide veragitation uhla lwe-800¡Ãf - 1500¡ããf ngaphandle kwesidingo sokusebenza okuthunyelwe okuthunyelwe. Kodwa-ke, ubukhulu bezindawo ezilonakalisayo bangadinga ukunxusa ngemuva kokufudumala noma ukusebenzisa i-304L. Uhlobo lwe-304L lunokuqukethwe kwekhabhoni ngo-0.03% noma ngaphansi.

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.

Uhlobo lokuxhumana lwe-Flange luvame ukuza ngeyunithi ephindwe kabili, ngama-washers kanye nama-bolts namantongomane okuxhuma komunye nomunye. (Ipayipi lifakwa ku-flange kuqala, bese i-valve neminye imishini ifakiwe ku-flange.) Lapho uxhuma lezi zingxenye, bese uqinisa izikulufo ezimbili ukuze bobabili baxhumene ndawonye. Ukuxhumeka kwe-Flange kuyinto elula, evumelana nezimo futhi okulondolozwa kwabasebenzi. Lapho ipayipi lilungiswa, izikulufo ezikwi-flange zingasuswa, futhi ipayipi elihambisanayo noma i-valve lingasuswa. Futhi buyisela esikhundleni samapayipi amasha nama-valve.

Amamaki abonakalayo athandwa kakhulu enziwe ngensimbi yekhabhoni. I-HT PIPLE AKUFANELE inikeze ama-Flanges we-Carbon Stone Pipe kanye nama-Flange Fittings, kepha futhi sinikeza ama-Flanges ensimbi engagqwali amaphrojekthi ahlukahlukene. Ama-Flate Flanges angayalwa ngemisebenzi yamanzi nezinhlelo zokusebenza ze-petrochemical. Ama-Flanges we-Bar kanye nama-gauge ama-gauge angakhiwa futhi nobukhulu kukhathalogi yethu.

Ubuso obuhlangene bendandatho lwenzelwe i-groove ehlolwe lapho kufakwa khona i-metal ring gasket ukuze kwakhiwe uphawu nge-flange eshayisanayo. Izindandatho zensimbi zitholakala ku-Oval noma i-Octagonal Shape. Izinto ezivame kakhulu zendandatho ezihlangene ezihlangene ziyinsimbi engama-316 engagqwali, okwenza kube yinto elungele izinhlelo ezilimazayo. Lesi sithombe ngenhla sibonisa i-gasket yendandatho kanye nokukhala okuhlangene kuqeda ku-flange.
