Iiflange ezingaboniyo ziyinxalenye ebalulekileyo kwiinkqubo zombhobho, zihlala zisetyenziselwa ukutywina ukuvuleka kwimibhobho okanye iinqanawa zokugcinwa, ukuhlolwa, okanye ukucoca. Ukuze kuqinisekiswe umgangatho, ukhuseleko kunye nokutshintshiselana kweeflange ezingaboniyo, i-International Organisation for Standardization (ISO) kunye neminye imibutho yemigangatho efanelekileyo iye yakhupha uluhlu lwemigangatho yamazwe ngamazwe ehlanganisa yonke imiba yoyilo, ukuveliswa kunye nokusetyenziswa kweeflange ezingaboniyo.
Nantsi eminye yemigangatho ephambili yehlabathi enxulumene neeflange ezingaboniyo kunye nemixholo yazo:
I-ASME B16.5
- Iiflange zemibhobho - iSigaba 1: Iiflange zentsimbi zombhobho wefektri kunye nenkonzo ngokubanzi: Lo mgangatho ugubungela iindidi ngeendidi zeeflange, kubandakanywa iiflange ezingaboniyo. Ezi ziquka ubungakanani, ukunyamezela, ukudibanisa umphezulu wokudibanisa kunye neemfuno zezinto ze-flange ze-flange eyimfama.
I-ASME B16.48
-2018 - I-Line Blanks: Umgangatho opapashwe yi-American Society of Mechanical Engineers (ASME) egubungela ngokukodwa iiflange ezingaboniyo, ezihlala zibizwa ngokuba "ziindawo ezingenanto." Lo mgangatho uchaza imilinganiselo, izixhobo, ukunyamezela kunye neemfuno zokuvavanya iiflange ezingaboniyo ukuqinisekisa ukuthembeka kwazo kwimizi-mveliso kunye nemibhobho yenkonzo ngokubanzi.
EN 1092-1
-2018 - IiFlanges kunye namalungu abo - Iiflethi zeesetyhula zemibhobho, iivalve, izixhobo kunye nezixhobo, i-PN ekhethiweyo - Icandelo le-1: Iiflethi zensimbi: Lo ngumgangatho waseYurophu ohlanganisa ukuyila, imilinganiselo, izinto eziphathekayo kunye neemfuno zokuMakisha. Ifanelekile kwiinkqubo zemibhobho eFransi, eJamani, eItali nakwamanye amazwe aseYurophu.
JIS B 2220
-2012 - Iiflange zemibhobho yentsimbi: Umgangatho woShishino waseJapan (JIS) ucacisa imilinganiselo, ukunyamezela kunye neemfuno zezinto eziphathekayo kwiiflange ezingaboniyo ukuhlangabezana neemfuno zeenkqubo zemibhobho yaseJapan.
Umgangatho ngamnye wamazwe ngamazwe ubandakanya oku kulandelayo:
Imilinganiselo kunye nokunyamezelana: Umgangatho uchaza ubungakanani boluhlu lwee-flanges ezingaboniyo kunye neemfuno ezinxulumene nokunyamezela ukuqinisekisa ukutshintshisana phakathi kwee-flanges ezingaboniyo eziveliswa ngabavelisi abahlukeneyo. Oku kunceda ukuqinisekisa ukungaguquguquki kunye nokutshintshiselana kweenkqubo zemibhobho.
Iimfuno zezinto eziphathekayo: Umgangatho ngamnye uchaza imigangatho yezinto ezifunekayo ukwenza iiflange ezingaboniyo, ngokuqhelekileyo i-carbon steel, insimbi engenasici, insimbi ye-alloy, njl. Ezi mfuno ziquka ukubunjwa kweekhemikhali zezinto eziphathekayo, iimpawu zomatshini kunye neemfuno zonyango lobushushu ukuqinisekisa ukuba i-flange eyimfama inayo. ukomelela okwaneleyo kunye nokumelana nomhlwa.
Indlela yokuvelisa: Imigangatho idla ngokubandakanya indlela yokuvelisa i-flanges eyimfama, kubandakanywa ukulungiswa kwezinto eziphathekayo, ukubunjwa, i-welding kunye nokunyanga ukushisa. Ezi ndlela zokuvelisa ziqinisekisa umgangatho kunye nokusebenza kweeflange eziyimfama.
Uvavanyo kunye nokuhlolwa: Umgangatho ngamnye ukwabandakanya iimfuno zovavanyo kunye nokuhlolwa kweeflange ezingaboniyo ukuqinisekisa ukuba zinokusebenza ngokukhuselekileyo nangokuthembekileyo ekusebenziseni okwenyani. Olu vavanyo lubandakanya uvavanyo loxinzelelo, ukuhlolwa kwe-weld, kunye novavanyo lomsebenzi wezinto eziphathekayo.
Imigangatho yamazwe ngamazwe iqinisekisa ukuhambelana kwehlabathi kunye nokutshintshana kweeflange ezingaboniyo. Nokuba kushishino lwe-oyile negesi, iikhemikhali, unikezelo lwamanzi okanye amanye amacandelo oshishino, le migangatho idlala indima ebalulekileyo ekuqinisekiseni ukhuseleko, ukuthembeka kunye nokusebenza koqhagamshelo lwemibhobho. Ngoko ke, xa ukhetha kwaye usebenzisa i-flanges eyimfama, kubalulekile ukuqonda nokuthobela imigangatho yamazwe ngamazwe esebenzayo ukuqinisekisa ukusebenza okuzinzileyo kunye nokhuseleko lwenkqubo yombhobho.
