Intshayelelo:
Izigqubuthelo zeFlange, ezaziwa ngokuba zii-blind plates okanye ii-blind flanges, zidlala indima ebalulekileyo kwinkqubo yesizwe yeflange standard. Ezi plates ziqinileyo, ezifana nezigqubuthelo zentsimbi, zizinto ezibalulekileyo ezisetyenziselwa ukuvala ukuvuleka kwemibhobho nokuthintela ukugcwala komxholo. Ngaphezu koko, ii-blind flanges zifumana usetyenziso kwiimeko ezahlukeneyo, ezifana nemibhobho yamanzi kunye namacandelo exeshana ngexesha lovavanyo loxinzelelo. Kule sikhokelo sibanzi, siza kujonga imigangatho yemveliso yee-blind flanges, sihlola imigangatho eyaziwayo efana ne-ANSI, i-DIN, i-JIS, i-BS, kunye nokunye. Ngaphezu koko, siza kukhanyisa amanqanaba entsimbi asetyenziswa ekwenzeni ii-blind flanges, siqinisekise ukuba uyayiqonda le nxalenye ibalulekileyo.
Isiqendu 1: Ukuqonda iiFlange Covers kunye nemisebenzi yazo
Izigqubuthelo zeflange, ezaziwa ngokuba ziiplati ezingaboniyo okanye iiflange ezingaboniyo, ziyinxalenye ebalulekileyo yeenkqubo zepayipi. Injongo yazo kukuvala imingxunya yepayipi ngokufanelekileyo nokuthintela umxholo ukuba ungaphuphumi. Zenziwe ngezinto eziqinileyo, izigqubuthelo zeflange zijikelezwe yimingxunya yebholiti ukuze zinamathele ngokuqinileyo. Zifana nezigqubuthelo zentsimbi eziqinileyo, zinokufumaneka kwiindlela ezahlukeneyo zoyilo, ezifana nezithe tyaba, eziphakanyisiweyo, ezigobileyo nezingqukuva, kunye neendawo zolwimi kunye nemingxunya. Ngokungafaniyo neeflanges zokuwelda ze-butt, iiflanges ezingaboniyo azinantamo. Ezi zinto zihlala zisetyenziswa ekupheleni kwemibhobho yamanzi, ukuqinisekisa ukuba akukho kuvuza okanye ukuphazamiseka okungalindelekanga.
Isiqendu 2: Ukuhlola iMigangatho yoMveliso weFlange engaboniyo
Iiflanges ezingaboniyo zilandela imigangatho ethile yemveliso ukuqinisekisa umgangatho, ukuhambelana, kunye nokuhambelana. Imigangatho eyaziwayo kushishino ibandakanya i-ANSI B16.5, DIN2576, JISB2220, KS B1503, BS4504, UNI6091-6099, ISO7005-1:1992, HG20601-1997, HG20622-1997, SH3406-1996, GB/T9123.1~9123.4-2000, JB/T86.1~86.2-1994. Umgangatho ngamnye uchaza iinkalo ezahlukeneyo zeeflanges ezingaboniyo, ezifana nobukhulu, iimfuno zezinto eziphathekayo, ukulinganiswa koxinzelelo, kunye neenkqubo zovavanyo. Kubalulekile ukujonga umgangatho othile ofanelekileyo kwiprojekthi yakho ukuqinisekisa ukusebenza kakuhle kweflanges ezingaboniyo kunye nokuhambelana nenkqubo yakho yepayipi.
Isiqendu 3: Iiklasi zeNsimbi eziVulwayo ezisetyenziswa kwiMveliso yeFlange ezingaboniyo
Ukukhethwa kwamanqanaba entsimbi kudlala indima ebalulekileyo ekuvelisweni kweeflanges ezingaboniyo, njengoko kuchaphazela ngokuthe ngqo ukuqina kwazo, amandla, kunye nokumelana nokugqwala. Amanqanaba entsimbi ahlukeneyo asetyenziswa ekwenzeni iiflanges ezingaboniyo, kuquka kodwa kungaphelelanga apho:
1. Intsimbi yekhabhoni: Ukhetho olungabizi kakhulu olunamandla agqwesileyo kunye nokumelana namaqondo obushushu aphezulu. Iindidi zentsimbi yekhabhoni eziqhelekileyo ezisetyenziswayo yi-ASTM A105, ASTM A350 LF2, kunye ne-ASTM A516 Gr. 70.
2. Intsimbi Engagqwaliyo: Ilungele ukusetyenziswa apho ukumelana nokugqwala kubalulekile. Iindidi zentsimbi engagqwaliyo ezidumileyo ziquka i-ASTM A182 F304/F304L, i-ASTM A182 F316/F316L, kunye ne-ASTM A182 F321.
3. Intsimbi ye-Alloy: La manqanaba entsimbi aphucula ukumelana kwe-blind flange kwi-stressors ezithile, ezifana namaqondo obushushu aphezulu okanye iindawo ezirhabaxa. Amanqanaba aqhelekileyo entsimbi ye-alloy asetyenziswayo yi-ASTM A182 F5, ASTM A182 F9, kunye ne-ASTM A182 F91.
Kubalulekile ukukhetha uhlobo olufanelekileyo lwentsimbi ngokusekelwe kwiimfuno ezithile zeprojekthi yakho, ucinga ngezinto ezifana nendawo yokusebenza, uxinzelelo, ubushushu, kunye nokuvezwa ziikhemikhali.
Isiqendu 4: Ukuqinisekisa iiFlanges ezingaboniyo ezikumgangatho ophezulu nezihambelanayo
Xa uthenga ii-blind flanges, kubalulekile ukuqinisekisa ukuba ziyahambelana nemigangatho yemveliso efanelekileyo kunye neziqinisekiso zomgangatho. Funa ababoneleli abathembekileyo abanamathela kwiinkqubo ezingqongqo zokuvelisa, beqinisekisa ukuba ii-blind flanges zabo ziyahlangabezana okanye zidlula iimfuno zoshishino. Ukongeza, cinga ngababoneleli ababonelela ngeziqinisekiso zovavanyo lwezinto (MTC) ukuze kulawulwe umgangatho ngokungqongqo. La maxwebhu aqinisekisa ukuba ii-blind flanges ziye zavavanywa ngokuyimfuneko, okuqinisekisa ukuba zifanelekile kwiprojekthi yakho.
Isiqendu 5: Isiphelo kunye neeNgcebiso zokugqibela
Iiflanges ezingaboniyo, ezaziwa ngokuba zizigqubuthelo zeflange okanye iipleyiti ezingaboniyo, zizinto ezibalulekileyo kwiinkqubo zemibhobho. Imveliso yazo inamathela kwimigangatho ethile ukuqinisekisa ukuhambelana nokuhambelana. Imigangatho yemveliso eyaziwayo efana ne-ANSI B16.5, i-DIN, i-JIS, kunye ne-BS ilawula ubukhulu beflanges ezingaboniyo, iimfuno zezinto ezibonakalayo, kunye novavanyo loxinzelelo. Ngaphezu koko, amanqanaba entsimbi afana nentsimbi yekhabhoni, intsimbi engatyiwayo, kunye nentsimbi ye-alloy akhethwa ngononophelo ukuqinisekisa ukusebenza kakuhle kunye nobude bexesha. Xa uthenga iiflanges ezingaboniyo, soloko ukhetha ababoneleli abathembekileyo ababeka phambili umgangatho kwaye banikeze iziqinisekiso ezifunekayo. Ngokuqonda imigangatho yemveliso yeeflanges ezingaboniyo kunye namanqanaba entsimbi, ungakhetha ngokuzithemba izinto ezifanelekileyo kwiinkqubo zakho zemibhobho, uqinisekise ukusebenza okusebenzayo nokukhuselekileyo.
