Intshayelelo:
Izigqubuthelo zeflange, ezaziwa ngokuba ziipleyiti ezingaboniyo okanye iiflange ezingaboniyo, zidlala indima ebalulekileyo kwinkqubo yesizwe yeflange.La macwecwe aqinileyo, afana nezigqubuthelo zentsimbi, zizinto ezibalulekileyo ezisetyenziselwa ukuvala ukuvuleka kwemibhobho kunye nokuthintela ukuphuphuma komxholo.Ngaphezu koko, iiflange ezingaboniyo zifumana izicelo kwiimeko ezahlukeneyo, njengemibhobho yesebe lonikezelo lwamanzi kunye namacandelo ethutyana ngexesha lovavanyo loxinzelelo.Kwesi sikhokelo sibanzi, siya kuphonononga kwimigangatho yokuvelisa iiflanges ezingaboniyo, sijonge imigangatho eyaziwayo njenge ANSI, DIN, JIS, BS, kunye nokunye.Ngaphaya koko, siya kukhanyisa kumanqanaba entsimbi aqeshwe ekwenzeni iiflange ezingaboniyo, siqinisekisa ukuqonda kwakho kweli candelo libalulekileyo.
Umhlathi 1: Ukuqonda amaQhuva eFlange kunye nemisebenzi yawo
Izigqubuthelo zeflange, ezaziwa ngokuba ziipleyiti eziyimfama okanye iiflange ezingaboniyo, ziyinxalenye yeenkqubo zemibhobho.Injongo yabo kukuthintela ukuvuleka kwemibhobho ngokufanelekileyo kunye nokukhusela iziqulatho ekuphuphumeni.Yenziwe ngezinto eziqinileyo, izigqubuthelo zeflange zijikelezwe yimingxuma yebholiti yokuncamathisela okukhuselekileyo.Ngokufana nezigqubuthelo zentsimbi ezomeleleyo, zinokufunyanwa kwiindlela ezahlukeneyo zokuyilwa, njengemcaba, ephakanyisiweyo, engqukuva neconvex, kunye nolwimi kunye nomphezulu wegroove.Ngokungafaniyo ne-butt welding flanges, iiflange ezingaboniyo azinayo intamo.La malungu adla ngokusetyenziswa ekupheleni kwemibhobho yesebe lonikezelo lwamanzi, ukuqinisekisa ukuba akukho kuvuza okungalindelekanga okanye ukuphazamiseka.
Umhlathi 2: Ukuphonononga iMigangatho yeMveliso yeFlange eyimfama
Iiflange ezingaboniyo zibambelela kwimigangatho ethile yokuvelisa ukuqinisekisa umgangatho, ukuhambelana, kunye nokuhambelana.Imigangatho eyaziwayo kushishino iquka ANSI B16.5, DIN2576, JISB2220, KS B1503, BS4504, UNI6091-6099, ISO7005-1: 1992, HG20622-1992-1992-1992-SHT1992 3.4- 2000, JB/T86.1~86.2-1994.Umgangatho ngamnye ubonakalisa imiba eyahlukeneyo yeeflange ezingaboniyo, ezinje ngemilinganiselo, iimfuno zemathiriyeli, iireyithingi zoxinzelelo, kunye neenkqubo zovavanyo.Kubalulekile ukubonisana nomgangatho othile ofanelekileyo kwiprojekthi yakho ukuze uqinisekise ukusebenza kakuhle kwe-blind flange kunye nokuhambelana nenkqubo yakho yombhobho.
Umhlathi 3: Ukutyhilwa kwamaBanga eNsimbi asetyenziswa kwiBlind Flange Manufacturing
Ukukhethwa kwamabakala ensimbi kudlala indima ebalulekileyo ekuveliseni iiflange ezingaboniyo, njengoko zichaphazela ngokuthe ngqo ukuqina kwazo, amandla kunye nokuchasana nokubola.Amanqanaba ahlukeneyo entsimbi aqeshwe kwimveliso ye-blind flange, kubandakanywa kodwa kungaphelelanga:
1. I-Carbon Steel: Inketho eneendleko ezinamandla kunye nokumelana nokushisa okuphezulu.Amanqanaba aqhelekileyo e-carbon steel asetyenziswayo yi-ASTM A105, ASTM A350 LF2, kunye ne-ASTM A516 Gr.70.
2. Intsimbi engatyiwayo: Ilungele usetyenziso apho ukuxhathisa umhlwa kubalulekile.Amabakala aziwayo ensimbi engenasici aquka i-ASTM A182 F304 / F304L, i-ASTM A182 F316 / F316L, kunye ne-ASTM A182 F321.
3. I-Alloy Steel: La manqanaba entsimbi aphakamisa ukuchasana kwe-flange eyimfama kwizinto ezixinzelelekileyo, ezifana nokushisa okuphezulu okanye iindawo ezinobungozi.Amanqanaba aqhelekileyo ensimbi ye-alloy asetyenziswa yi-ASTM A182 F5, ASTM A182 F9, kunye ne-ASTM A182 F91.
Kubalulekile ukukhetha ibakala lentsimbi elifanelekileyo ngokusekwe kwiimfuno ezithile zeprojekthi yakho, uqwalasela izinto ezinjengendawo yokusebenza, uxinzelelo, ubushushu, kunye nokuvezwa kweekhemikhali.
Umhlathi 4: Ukuqinisekisa ukuba uMgangatho oPhezulu kunye nokuThobela iiFlange zeemfama
Xa kuthengwa iiflange ezingaboniyo, kubalulekile ukuqinisekisa ukuba zihambelana nemigangatho efanelekileyo yemveliso kunye neziqinisekiso zomgangatho.Funa ababoneleli abathembekileyo ababambelela kwiinkqubo ezingqongqo zokuvelisa, beqinisekisa ukuba iiflange zabo ezingaboniyo ziyahlangabezana okanye zigqithise iimfuno zeshishini.Ukongeza, qwalasela abathengisi ababonelela ngezatifikethi zovavanyo lwezinto (MTC) zolawulo olungqongqo lomgangatho.La maxwebhu aqinisekisa ukuba iiflange ezingaboniyo ziye zavavanywa ngokufanelekileyo, ziqinisekisa ukufaneleka kwazo kwiprojekthi yakho.
Umhlathi 5: Isiphelo kunye neeNgcebiso zokuGqibela
Iiflange ezingaboniyo, ezikwabizwa ngokuba zizigqubuthelo zeflange okanye iipleyiti ezingaboniyo, zizinto eziyimfuneko kwiinkqubo zemibhobho.Imveliso yabo ihambelana nemigangatho ethile ukuqinisekisa ukuhambelana nokuhambelana.Imigangatho yemveliso eyaziwayo efana ne-ANSI B16.5, i-DIN, i-JIS, kunye ne-BS ichaza imilinganiselo ye-flange eyimfama, iimfuno zezinto eziphathekayo, kunye noxinzelelo loxinzelelo.Ngaphezu koko, amabakala ensimbi afana ne-carbon steel, insimbi engenasici, kunye nentsimbi ye-alloy akhethwe ngononophelo ukuqinisekisa ukusebenza kakuhle kunye nokuphila ixesha elide.Xa ufumana iiflange ezingaboniyo, soloko ukhetha ababoneleli abathembekileyo ababeka phambili umgangatho kwaye banikeze iziqinisekiso eziyimfuneko.Ngokuqonda imigangatho yemveliso yee-blind flanges kunye namabakala entsimbi, unokukhetha ngokuzithemba amacandelo afanelekileyo kwiinkqubo zakho zemibhobho, uqinisekise ukusebenza ngokufanelekileyo nangokukhuselekileyo.
