Intshayelelo esisiseko yeflange
Iiflange zemibhobho kunye neegaskets zazo kunye nezibophelelo ngokudibeneyo zibizwa ngokuba yi-flange joints.
Isicelo:
I-Flange joint luhlobo lwecandelo elisetyenziswa ngokubanzi kuyilo lobunjineli.Yinxalenye ebalulekileyo yoyilo lwemibhobho, izifakelo zemibhobho kunye neevalvu, kananjalo yinxalenye ebalulekileyo yezixhobo nezixhobo zezixhobo (ezifana nomngxuma, igeyiji yeglasi yokubona, njl. njl.).Ukongeza, ii-flange joints zihlala zisetyenziswa kwezinye iinkalo, ezifana neziko zoshishino, ubunjineli be-thermal, unikezelo lwamanzi kunye ne-drainage, ukufudumeza kunye nomoya, ukulawula ngokuzenzekelayo, njl.
Ubume bemathiriyeli:
Intsimbi eyenziweyo, i-WCB carbon steel, i-stainless steel, i-316L, i-316, i-304L, i-304, i-321, i-chrome-molybdenum steel, i-chrome-molybdenum-vanadium steel, i-molybdenum titanium, i-rubber lining, i-fluorine lining materials.
Ukuhlelwa:
I-flat welding flange, i-neck flange, i-butt welding flange, i-ring edibanisa i-flange, i-socket flange, kunye nepleyiti eyimfama, njl.
Umgangatho wesiGqeba:
Kukho uchungechunge lwe-GB (umgangatho wesizwe), uchungechunge lwe-JB (isebe lomatshini), uchungechunge lwe-HG (isebe lekhemikhali), i-ASME B16.5 (i-American standard), i-BS4504 (i-British standard), i-DIN (umgangatho waseJamani), i-JIS (umgangatho waseJapan).
Inkqubo esemgangathweni yombhobho wamazwe ngamazwe:
Kukho imigangatho emibini engundoqo yeflange yombhobho wamazwe ngamazwe, ezizezi, inkqubo yeflange yombhobho waseYurophu emelwe yi-DIN yaseJamani (kubandakanywa neyayisakuba yiSoviet Union) kunye nenkqubo yeflange yombhobho waseMelika emelwe yi-American ANSI pipe flange.
1. Ipleyiti yohlobo lweflange yokuwelda
inzuzo:
Kukulungele ukufumana imathiriyeli, kulula ukwenza, ixabiso eliphantsi kwaye lisetyenziswa ngokubanzi.
Izinto ezingeloncedo:
Ngenxa yobunzima bayo, akufanele isetyenziswe kwiinkqubo zemibhobho yenkqubo yeekhemikhali kunye neemfuno zokubonelela kunye nemfuno, ukutsha, ukuqhuma kunye neqondo eliphezulu le-vacuum, kwaye kwiimeko ezinobungozi kakhulu.
Uhlobo lomphezulu wokutywina lunemigangatho ethe tyaba kunye neconvex.
2. I-flat welding flange enentamo
I-slip-on welding flange enentamo yeyomgangatho wesizwe wenkqubo yomgangatho weflange.Yindlela enye yeflange esemgangathweni kazwelonke (eyaziwa ngokuba yi-GB flange) kunye nenye yeeflange ezisetyenziswa ngokuqhelekileyo kwisixhobo okanye kwipayipi.
inzuzo:
Ukufakwa kwi-site kukulungele, kwaye inkqubo ye-welding seam rubbing ingashiywa
Izinto ezingeloncedo:
Ukuphakama kwentamo ye-slip-on welding flange enentamo iphantsi, ephucula ukuqina kunye nokuthwala umthamo we-flange.Xa kuthelekiswa ne-butt welding flange, umsebenzi we-welding mkhulu, ukusetyenziswa kwentonga ye-welding kuphezulu, kwaye ayikwazi ukumelana nobushushu obuphezulu kunye noxinzelelo oluphezulu, ukugoba ngokuphindaphindiweyo kunye nokuguquguquka kobushushu.
3. I-flange ye-welding ye-Neck butt
Iifom zomphezulu wokutywina we-neck butt welding flange ziquka:
RF, FM, M, T, G, FF.
inzuzo:
Uqhagamshelo alulula ukukhubaza, umphumo wokutywina ulungile, kwaye usetyenziswa ngokubanzi.Ilungele imibhobho enokuguquguquka okukhulu kobushushu okanye uxinzelelo, ubushushu obuphezulu, uxinzelelo oluphezulu kunye nobushushu obuphantsi, kunye nemibhobho ehambisa imithombo yeendaba ebiza kakhulu, imithombo yeendaba ezinokutsha kunye neziqhumayo, kunye neegesi ezinetyhefu.
Izinto ezingeloncedo:
I-neck butt-welding flange is bulky, bulky, ibiza kakhulu, kwaye kunzima ukuyifaka nokufumana indawo.Ngoko ke, kulula ukungqubeka ngexesha lokuhamba.
4. I-socket welding flange
I-socket welding flangeyiflange edityaniswe ngombhobho wentsimbi kwelinye icala kwaye ibotshelelwe kwelinye icala.
Uhlobo lomphezulu wokutywina:
Ubuso obuphakanyisiweyo (RF), ubuso be-concave kunye ne-convex (MFM), ubuso be-tenon kunye ne-groove (TG), ubuso obuhlangeneyo beringi (RJ)
Ubungakanani besicelo:
I-boiler kunye nesitya soxinzelelo, i-petroleum, ikhemikhali, i-shipbuilding, i-pharmaceutical, i-metallurgy, oomatshini, ukunyathela ukutya kwe-elbow kunye namanye amashishini.
Ngokuqhelekileyo isetyenziswe kwiipayipi kunye ne-PN ≤ 10.0MPa kunye ne-DN ≤ 40.
5. Iflange enemisonto
I-flange ene-threaded yi-flange engeyi-welded, eyenza umngxuma wangaphakathi we-flange ibe yintambo yombhobho kwaye idibanise nombhobho odibeneyo.
inzuzo:
Xa kuthelekiswa neflange yewelding ecaba okanye i-butt welding flange,iflange enemisontoineempawu zofakelo olufanelekileyo kunye nokugcinwa, kwaye inokusetyenziswa kwezinye iipayipi ezingavumelekanga ukuba zifakwe kwisiza.I-alloy steel flange inamandla okwaneleyo, kodwa akukho lula ukuyidibanisa, okanye ukusebenza kwe-welding ayilungile, i-flange ene-threaded nayo inokukhethwa.
Izinto ezingeloncedo:
Xa ubushushu bombhobho buguquka kabukhali okanye ubushushu bungaphezulu kwe-260 ℃ kwaye bungaphantsi kuno-45 ℃, kuyacetyiswa ukuba ungasebenzisi iflange enemisonto ukunqanda ukuvuza.
6. I-flange eyimfama
Ikwabizwa ngokuba yi-flange cover kunye nepleyiti eyimfama.Yiflange engenamingxuma embindini wokutywina iplagi yombhobho.
Umsebenzi uyafana naleyo yentloko edityanisiweyo kunye nekepusi yombhobho ephothiweyo, ngaphandle kokoiflange eyimfamakunye nentambo yombhobho wentambo inokususwa nanini na, ngelixa intloko edibeneyo ayikwazi.
Indawo yokutywina yesigqubuthelo seflange:
I-Flat (FF), ubuso obuphakanyisiweyo (RF), ubuso be-concave kunye ne-convex (MFM), ubuso be-tenon kunye ne-groove (TG), ubuso obuhlangeneyo beringi (RJ)
