Umgaqo wokutywinwa we-ANSIiiflange ilula kakhulu: iindawo ezimbini zokutywina zebholithi zicudisa i-gasket yeflange kwaye yenze itywina.Kodwa oku kukhokelela ekutshatyalalisweni kwetywina.Ukugcina itywina, kufuneka kugcinwe ibholt enkulu.Ngenxa yesi sizathu, ibholithi kufuneka yenziwe ibe nkulu.Iibholiti ezinkulu kufuneka zihambelane namantongomane amakhulu, oku kuthetha ukuba iibholiti ezinkulu zedayamitha ziyafuneka ukudala iimeko zokuqinisa amantongomane.Njengoko wonke umntu uyazi, ubukhulu bobubanzi bebholithi, i-flange esebenzayo iya kugoba.Indlela yodwa kukunyusa ubuninzi bodonga lwenxalenye yeflange.Isixhobo sonke siya kufuna ubungakanani obukhulu kunye nobunzima, oba yingxaki ekhethekileyo kwiindawo ezingaselunxwemeni kuba ubunzima buhlala bungumba ophambili ekufuneka abantu bawuthathele ingqalelo kule meko.Ngaphezu koko, ngokusisiseko, iiflange ze-ANSI zitywina elingasebenziyo.Ifuna i-50% yomthwalo webholithi oza kusetyenziselwa ukukhupha i-gasket, ngelixa kuphela i-50% yomthwalo osetyenziselwa ukugcina uxinzelelo.

Nangona kunjalo, eyona nto ingalunganga yoyilo lweeflange ze-ANSI kukuba abanakuqinisekisa ukuba akukho kuvuza.Oku kukunqongophala koyilo lwayo: uxhulumaniso luyaguquguquka, kwaye imithwalo ye-cyclical efana nokwandiswa kwe-thermal kunye nokuguquguquka kuya kubangela intshukumo phakathi kwendawo ye-flange, ichaphazele umsebenzi we-flange, kwaye yonakalise ingqibelelo ye-flange, eya kuthi ekugqibeleni ikhokelele kwi-flange. ukuvuza.
