Isingeniso esiyisisekelo se-flange
Ama-pipe flanges kanye nama-gaskets awo nezixhumi zawo zibizwa ngokuhlanganyela ngokuthi ama-flange joints.
Isicelo:
I-Flange joint iwuhlobo lwengxenye esetshenziswa kabanzi ekwakhiweni kobunjiniyela.Kuyingxenye ebalulekile yokwakhiwa kwamapayipi, okokufakwa kwamapayipi namavalvu, futhi kuyingxenye ebalulekile yezingxenye zemishini nemishini (njengomgodi, igeji yezinga lengilazi yokubona, njll.).Ngaphezu kwalokho, amalunga e-flange avame ukusetshenziswa kwezinye iziyalo, njengeziko lezimboni, ubunjiniyela bokushisa, ukuhlinzekwa kwamanzi kanye nokukhipha amanzi, ukushisa nokukhipha umoya, ukulawula okuzenzakalelayo, njll.
Ukuma kwempahla:
Insimbi efojiwe, i-WCB carbon steel, insimbi engagqwali, 316L, 316, 304L, 304, 321, insimbi ye-chrome-molybdenum, insimbi ye-chrome-molybdenum-vanadium, i-molybdenum titanium, ulwelwesi lwerabha, izinto zokwakhiwa kwe-fluorine.
Ukuhlukaniswa:
I-flat welding flange, i-neck flange, i-butt welding flange, i-flange yokuxhuma indandatho, i-socket flange, ne-blind plate, njll.
Izinga eliphezulu:
Kukhona uchungechunge lwe-GB (okujwayelekile kazwelonke), uchungechunge lwe-JB (umnyango wemishini), uchungechunge lwe-HG (umnyango wamakhemikhali), i-ASME B16.5 (i-American standard), i-BS4504 (i-British standard), i-DIN (i-German standard), i-JIS (i-Japanese standard).
Uhlelo olujwayelekile lwephayiphi flange:
Kunezindinganiso ezimbili eziyinhloko zamapayipi omhlaba jikelele we-flange, okuyisistimu yamapayipi e-European flange amelwe yi-DIN yaseJalimane (kuhlanganise ne-Soviet Union yangaphambili) kanye nesistimu ye-flange yamapayipi aseMelika emelwe i-American ANSI ipayipi flange.
1. Uhlobo lwe-plate flat welding flange
inzuzo:
Kulula ukuthola izinto zokwakha, ezilula ukwenza, izindleko eziphansi futhi ezisetshenziswa kabanzi.
Ububi:
Ngenxa yokuqina kwayo okungekuhle, akufanele isetshenziswe ezinhlelweni zamapayipi ezinqubo zamakhemikhali ezinezidingo zokuhlinzekwa nokufunwa, ukuvutha, ukuqhuma kanye nezinga eliphezulu le-vacuum, futhi ezimweni eziyingozi kakhulu.
Uhlobo lwendawo yokuvala lunezindawo eziyisicaba neziqondile.
2. I-flat welding flange enentamo
I-slip-on welding flange enentamo ingeyesistimu evamile ye-flange ejwayelekile.Iwuhlobo olulodwa lwe-flange olujwayelekile lukazwelonke (olwaziwa nangokuthi i-GB flange) kanye nelinye lama-flange avame ukusetshenziswa emishinini noma kumapayipi.
inzuzo:
Ukufakwa esizeni kulula, futhi inqubo ye-welding seam rubbing ingashiywa
Ububi:
Ukuphakama kwentamo ye-slip-on welding flange enentamo iphansi, okuthuthukisa ukuqina kanye nomthamo wokuthwala we-flange.Uma kuqhathaniswa ne-butt welding flange, umsebenzi wokushisela mkhulu, ukusetshenziswa kwenduku yokushisela kuphezulu, futhi akukwazi ukumelana nokushisa okuphezulu nokucindezela okukhulu, ukugoba okuphindaphindiwe kanye nokushintshashintsha kwezinga lokushisa.
3. I-flange yokushisela izinqe zentamo
Izinhlobo ze-sealing surface ye-neck butt welding flange zihlanganisa:
RF, FM, M, T, G, FF.
inzuzo:
Ukuxhumeka akulula ukukonakalisa, umphumela wokuvala muhle, futhi usetshenziswa kabanzi.Ilungele amapayipi anokushintshashintsha okukhulu kwezinga lokushisa noma ingcindezi, izinga lokushisa eliphezulu, umfutho ophezulu kanye nezinga lokushisa eliphansi, kanye namapayipi athutha imidiya ebizayo, imidiya evuthayo neziqhumane, namagesi anobuthi.
Ububi:
I-neck butt-welding flange inkulu, inkulu, iyabiza, futhi kunzima ukuyifaka nokuyithola.Ngakho-ke, kulula ukugoqa ngesikhathi sokuthutha.
4. I-socket welding flange
I-socket welding flangeiyi-flange eshiselwe ngepayipi lensimbi komunye umkhawulo futhi iboshwe ngakolunye uhlangothi.
Uhlobo lwendawo yokuvala:
Ubuso obuphakanyisiwe (RF), ubuso be-concave kanye ne-convex (MFM), ubuso be-tenon kanye ne-groove (TG), ubuso obuhlangene beringi (RJ)
Ububanzi besicelo:
Isitsha se-boiler nengcindezi, i-petroleum, amakhemikhali, ukwakha imikhumbi, imithi, i-metallurgy, imishini, ukunyathela ukudla kwe-elbow nezinye izimboni.
Okuvame ukusetshenziswa kumapayipi ane-PN ≤ 10.0MPa kanye ne-DN ≤ 40.
5. I-Flange enemicu
I-flange ene-threaded iyi-flange engahlanganisiwe, ecubungula imbobo engaphakathi ye-flange ibe intambo yepayipi bese ixhuma nepayipi elinentambo.
inzuzo:
Uma kuqhathaniswa ne-flange ye-welding flat noma i-butt welding flange,i-flange enentamboinezici zokufakwa nokugcinwa okulula, futhi ingasetshenziswa kwamanye amapayipi angavunyelwe ukushiselwa esizeni.I-alloy steel flange inamandla anele, kepha akulula ukushisela, noma ukusebenza kwe-welding akukuhle, i-flange enentambo nayo ingakhethwa.
Ububi:
Uma izinga lokushisa lepayipi lishintsha kakhulu noma izinga lokushisa lingaphezulu kuka-260 ℃ futhi lingaphansi kuka-45 ℃, kutuswa ukuthi ungasebenzisi i-flange enentambo ukugwema ukuvuza.
6. I-flange eyimpumputhe
Kwaziwa nangokuthi ikhava ye-flange nepuleti eliyimpumputhe.Kuyi-flange engenazimbobo phakathi kokuvala ipulaki yepayipi.
Umsebenzi uyafana nalowo wekhanda elishiselwe kanye nekepisi yepayipi ewuchungechunge, ngaphandle kwalokhoi-blind flangefuthi threaded pipe cap ingasuswa noma nini, kuyilapho ikhanda ezishiselwe ayikwazi.
Indawo yokuvala ikhava ye-Flange:
I-Flat (FF), ubuso obuphakanyisiwe (RF), ubuso be-concave kanye ne-convex (MFM), ubuso be-tenon kanye ne-groove (TG), ubuso obuhlangene beringi (RJ)
