Isingeniso:
Izembozo ze-Flange, ezaziwa nangokuthi amapuleti angaboni noma ama-blind flange, adlala indima ebalulekile ohlelweni olujwayelekile lwe-flange. Lezi zingcwecwe eziqinile, ezifana nezembozo zensimbi, ziyizingxenye ezibalulekile ezisetshenziselwa ukuvimba ukuvuleka kwamapayipi nokuvimbela ukuchichima kokuqukethwe. Ngaphezu kwalokho, ama-flange ayimpumputhe athola izinhlelo zokusebenza ezimweni ezihlukahlukene, njengamapayipi amagatsha okunikezela ngamanzi kanye nezingxenye zesikhashana ngesikhathi sokuhlolwa kwengcindezi. Kulo mhlahlandlela obanzi, sizohlola amazinga okukhiqiza ama-blind flanges, sihlole amazinga adumile njenge-ANSI, i-DIN, i-JIS, i-BS, nokuningi. Ngaphezu kwalokho, sizokhanyisa amabanga ensimbi asetshenziswa ekukhiqizeni ama-blind flange, siqinisekise ukuthi uyasiqonda lesi sici esibalulekile.
Isigaba 1: Ukuqonda Amakhava EFlange Nemisebenzi Yawo
Izembozo ze-Flange, ezivame ukubizwa ngokuthi amapuleti ayimpumputhe noma ama-blind flange, ayingxenye ebalulekile yezinhlelo zamapayipi. Inhloso yabo ukuvimbela ukuvuleka kwamapayipi ngokuphumelelayo nokuvimbela okuqukethwe ekuchichimeni. Ezenziwe ngezinto eziqinile, amakhava e-flange azungezwe izimbobo zamabholithi ukuze kunamathiselwe okuvikelekile. Njengezembozo zensimbi eziqinile, zingatholakala emiklamweni ehlukahlukene, enjengesicaba, ephakanyisiwe, e-concave ne-convex, nolimi kanye nezindawo zemifula. Ngokungafani nama-butt welding flange, ama-flange ayimpumputhe awanayo intamo. Lezi zingxenye ngokuvamile zisetshenziswa ekupheleni kwamapayipi egatsha okunikezwa kwamanzi, ukuqinisekisa ukuthi akukho ukuvuza okungalindelekile noma ukuphazamiseka.
Isigaba 2: Ukuhlola Amazinga Okukhiqiza Ama-Blind Flange
Ama-blind flange anamathela kumazinga athile okukhiqiza ukuze kuqinisekiswe ikhwalithi, ukuhambisana, nokuhambisana. Izindinganiso ezaziwayo embonini zifaka i-ANSI B16.5, DIN2576, JISB2220, KS B1503, BS4504, UNI6091-6099, ISO7005-1:1992, HG20601-1997, HG20622-391-1997-SHT1961 23.4- 2000, JB/T86.1~86.2-1994. Izinga ngalinye libonisa izici ezihlukahlukene zama-blind flange, njengobukhulu, izimfuneko zezinto ezibonakalayo, izilinganiso zokucindezela, nezinqubo zokuhlola. Kubalulekile ukubonana nezinga elithile elihambisana nephrojekthi yakho ukuze uqinisekise ukusebenza kahle kwe-blind flange nokuhambisana nohlelo lwakho lwamapayipi.
Isigaba 3: Ukwembula Amabanga Ensimbi Asetshenziswa Ekwenziweni Kwe-Blind Flange
Ukukhethwa kwamabanga ensimbi kudlala indima ebalulekile ekukhiqizeni ama-blind flange, njengoba kuthinta ngokuqondile ukuqina kwawo, amandla, kanye nokumelana nokugqwala. Amamaki ensimbi ahlukahlukene asetshenziswa ekukhiqizeni i-blind flange, okuhlanganisa kodwa kungagcini nje:
1. I-Carbon Steel: Inketho engabizi kakhulu enamandla amakhulu kanye nokumelana nokushisa okuphezulu. Amabanga ajwayelekile e-carbon steel asetshenziswa yi-ASTM A105, ASTM A350 LF2, kanye ne-ASTM A516 Gr. 70.
2. Insimbi Engagqwali: Ilungele ukusetshenziswa lapho ukumelana nokugqwala kubalulekile. Amabanga ensimbi engagqwali adumile ahlanganisa i-ASTM A182 F304/F304L, i-ASTM A182 F316/F316L, ne-ASTM A182 F321.
3. Insimbi ye-alloy: Lawa mabanga ensimbi athuthukisa ukumelana kwe-blind flange kuzicindezelo ezithile, njengamazinga okushisa aphezulu noma izindawo ezigqwalayo. Amamaki ensimbi ajwayelekile asetshenziswa yi-ASTM A182 F5, ASTM A182 F9, kanye ne-ASTM A182 F91.
Kubalulekile ukukhetha izinga lensimbi elifanele ngokusekelwe ezindingweni ezithile zephrojekthi yakho, ucabangela izici ezifana nendawo yokusebenza, ingcindezi, izinga lokushisa, nokuchayeka kwamakhemikhali.
Isigaba 4: Ukuqinisekisa Ikhwalithi Ephakeme Nezimpumputhe Ezithobelayo
Lapho uthenga ama-blind flange, kubalulekile ukuqinisekisa ukuthi athobelana namazinga okukhiqiza afanelekile kanye nezitifiketi zekhwalithi. Funa abahlinzeki abathembekile abanamathela ezinqubweni eziqinile zokukhiqiza, oqinisekisa ukuthi ama-blind flanges ayahlangabezana noma adlule izimfuneko zemboni. Ukwengeza, cabangela abahlinzeki abahlinzeka ngezitifiketi zokuhlolwa kwezinto (MTC) zokulawula ikhwalithi okuqinile. Le mibhalo iqinisekisa ukuthi ama-blind flanges ahlolwe okudingekile, okuqinisekisa ukufaneleka kwawo kuphrojekthi yakho.
Isigaba 5: Isiphetho kanye Nezincomo Zokugcina
Ama-blind flange, aziwa nangokuthi izembozo ze-flange noma amapuleti angaboni, ayizingxenye ezibalulekile zesistimu yamapayipi. Ukukhiqizwa kwazo kubambelela kumazinga athile ukuze kuqinisekiswe ukuhambisana nokuhambisana. Amazinga okukhiqiza adumile afana ne-ANSI B16.5, i-DIN, i-JIS, ne-BS inquma ubukhulu be-blind flange, izidingo zezinto ezibonakalayo, nezilinganiso zokucindezela. Ngaphezu kwalokho, amamaki ensimbi njenge-carbon steel, insimbi engagqwali, ne-alloy steel akhethwe ngokucophelela ukuze kuqinisekiswe ukusebenza kahle nokuphila isikhathi eside. Lapho uthenga ama-blind flange, khetha njalo abahlinzeki abathembekile ababeka phambili ikhwalithi futhi banikeze izitifiketi ezidingekayo. Ngokuqonda amazinga okukhiqiza ama-blind flanges kanye namabanga ensimbi, ungakhetha ngokuzethemba izingxenye ezifanele zamasistimu akho wamapayipi, uqinisekise ukusebenza kahle nokuphephile.
