Kuthatha umsebenzi omninzi ukwenza i-butt welding flanges, kwaye ngenxa yokuba ii-butt ze-welding flanges zineendleko eziphezulu zokuvelisa, ukufudumeza kwangaphambili kuyimfuneko rhoqo.Ukuguqulwa kwezinto ezikrwada kunye nenkqubo yokuguqulwa okunxulumene nobushushu kunye neempawu zomatshini wemodeli yezibalo yaziwa njengeflange yokulinganisa ikhompyuter.Le nkqubo ye-deformation iqhutyelwa ngoncedo lwekhompyutheni yekhompyutheni nangaliphi na ixesha xa imeko yoxinzelelo, ubunzima, kunye nokusabalalisa kweqondo lokushisa.Ukulinganisa ngokomzimba okwenziwe ngekhompyutha kunye nokulinganisa inkqubo kunokuxhasana kunye nokuphuculana.I-butt welding flanges inzima kakhulu ukwenza, kwaye ukufudumeza kwangaphambili kuyafuneka ngokuqhelekileyo ngenxa yeendleko eziphezulu zokwenza iiflange ezinkulu ze-butt welding.I-Computer simulation flange ligama elisetyenziswa ukuchaza indlela imathiriyeli ekrwada eguquka ngayo kunye nendlela iqondo lobushushu kunye neempawu zomatshini zemodeli yezibalo eziguqukayo.Ukulinganisa kwekhompyutheni kusetyenziselwa ukwenza le nkqubo yokuguqulwa nanini na iimeko zoxinzelelo, ubunzima, kunye nokusabalalisa ubushushu zidibene.Ukulinganisa kwenkqubo yekhompyutha kunye nokulinganisa ngokomzimba kunokuxhamla kunye nokuhambelana.
Inkqubo ye-European pipe flange, equka i-Soviet Union yangaphambili, imelwe yi-DIN yaseJamani, kwaye inkqubo ye-pipe flange yaseMelika imelwe yi-American ANSI pipe flange.Le migangatho mibini yeyona iphambili isetyenziswa kumazwe ngamazwe.I-Japan JIS tube flanges yenye inketho, nangona impembelelo yazo yamazwe ngamazwe iyancipha ngenxa yokuba isetyenziselwa kuphela imisebenzi yoluntu kwiindawo zepetrochemical.Oku kulandelayo kukujongwa okusisiseko kweeflange zemibhobho ezisetyenziswa kwisizwe ngasinye:
1.IJamani kunye nelizwe elalisakuba yiSoviet Union ngamalungu amabini esikhokelo senkqubo yaseYurophu.
2.I-ANSI B16.5 kunye ne-ANSI B 16.47 imigangatho yeFlange yenkqubo yombhobho waseMelika
3.Kukho imigangatho yecasing flange eyahlukileyo yeeflange zemibhobho yamazwe amabini ahlukeneyo.
Ukuqukumbela, iinkqubo ezimbini ezihlukeneyo kunye nezingatshintshiyo ze-pipe flange ezenza umgangatho wehlabathi jikelele wee-flanges zepayipi zilandelayo: inkqubo ye-pipe flange yaseYurophu, emelwe yiJamani;kunye nenkqubo yeflange yombhobho waseMelika, emelwe yiUnited States.
I-International Organisation for Standardization ipapashe umgangatho we-pipe flange owaziwa ngokuba yi-IOS7005-1 kwi-1992. Lo mgangatho udibanisa imigangatho ye-pipe flange evela eJamani nase-United States.
