I-under-torquing inokubangela ukuvuza, ngelixa i-over-torquing inokonakalisa i-flanges okanye i-gaskets. Kubalulekile ukusebenzisa amaxabiso e-torque afanelekileyo ngokusekelwe kwizinto ezifana nobukhulu bebholiti, izinto eziphathekayo, kunye nokuthambisa.
Ukongeza kumaxabiso etorque, iindlela ezifanelekileyo zokubopha ibhawudi zikwabandakanya ukuqwalaselwa okunje ngokulandelelana kokuqina kwebholithi kunye nepateni. Iibholithi kufuneka ziqiniswe kulandelelwano oluthile ukuqinisekisa ngokulinganayo ukusasazwa kwamandla kuwo wonke umdibaniso weflange. Oku kunceda ukuthintela ukuvuza kunye nokuqinisekisa ukuba i-joint ixhunyiwe ngokukhuselekileyo. Ubuchwephesha obufanelekileyo bokubholitha buyimfuneko ekuqinisekiseni amalunga eflange aqinileyo kwaye anokwethenjelwa.
Imiba echaphazela iMfezeko yeFlange Joints
Izinto ezininzi zinokuchaphazela ingqibelelo yamalungu e-flange, kuquka ukuyila, ukhetho lwezinto eziphathekayo, iindlela zokufakela, kunye neemeko zokusingqongileyo. Ukuqwalaselwa ngokufanelekileyo kwezi zinto kubalulekile ukuqinisekisa ukuba i-flange joints eqinile kwaye inokuthenjwa.
Enye into ebalulekileyo echaphazela ingqibelelo edibeneyo ye-flange kuyilo. Uyilo lwe-flange joint kufuneka luthathele ingqalelo izinto ezifana nobushushu, uxinzelelo, uhlobo lwe-fluid, kunye nobungakanani benkqubo. Uyilo olufanelekileyo lubalulekile ukuqinisekisa ukuba iiflange zixhunyiwe ngokukhuselekileyo kwaye itywina eliqinileyo lenziwe phakathi kwabo.
Ukukhethwa kwezinto eziphathekayo yenye into ebalulekileyo echaphazela ingqibelelo ye-flange. Ukukhethwa kwezinto eziphathekayo kwiiflange kunye ne-gaskets kufuneka kuthathelwe ingqalelo izinto ezifana nobushushu, uxinzelelo, ukuhambelana kweekhemikhali, kunye neemfuno zenkqubo. Ukusebenzisa imathiriyeli engalunganga kunokukhokelela ekuvuzeni, umhlwa, okanye eminye imiba ebeka esichengeni imfezeko yendibaniselwano.
Iindlela zokufakela zikwadlala indima ebalulekileyo ekuqinisekiseni ukuba amalungu eflange awomeleleyo nathembekileyo. Iibholiti ezifanelekileyo kunye neendlela ezifanelekileyo zokubethelela kufuneka zisetyenziswe ukuqinisekisa ukuba iibholithi ziqinisiwe kwixabiso elichanekileyo letorque kunye nokuba itywina eliqinileyo lenziwa phakathi kweeflanges.. Ukwengeza, ukufakwa kwe-gasket ngokufanelekileyo kubalulekile ukukhusela ukuvuza kunye nokugcina ingqibelelo edibeneyo.
Iimeko zokusingqongileyo zinokuchaphazela ingqibelelo yamalungu e-flange. Izinto ezifana nokuguquguquka kobushushu, ukuba sesichengeni kwiikhemikhali ezonakalisayo, okanye ukungcangcazela kunokuchaphazela ukusebenza komdibaniso weflange.

Iindlela ezigqwesileyo zokuGcinwa kweFlange ezomeleleyo kunye nezithembekileyo
Ukugcinwa okufanelekileyo kubalulekile ukuze kuqinisekiswe ukuba i-flange eqinile kwaye inokuthenjwa. Ukuhlolwa rhoqo kunye nokugcinwa kunokunceda ukuthintela ukuvuza, umhlwa, okanye eminye imiba ebeka esichengeni imfezeko edibeneyo.
Enye inkalo ebalulekileyo yokugcina i-flange joints eqinile kwaye inokuthenjwa kukuhlolwa rhoqo. Amalungu e-flange kufuneka ahlolwe iimpawu zokuvuza, umhlwa, okanye eminye imiba enokubeka esichengeni ingqibelelo yabo. Nayiphi na imiba kufuneka iqwalaselwe ngokukhawuleza ukuthintela umonakalo ongakumbi okanye ukungaphumeleli.
Ukongeza ekuhloleni, Ukugcinwa rhoqo okufana nokutshintshwa kwegasket okanye ukuqiniswa kwebholithi kunokuba yimfuneko ukugcina amalungu eflange anamandla kwaye athembekileyo.. Iigaskets kufuneka zihlolwe rhoqo ngeempawu zokuguga okanye umonakalo, kunye nokutshintshwa njengoko kufuneka ukuthintela ukuvuza. Iibholithi kufuneka zijongwe ngamaxesha athile ukuqinisekisa ukuba ziqinisiwe kwixabiso elichanekileyo letorque.
Uqeqesho olufanelekileyo lwabasebenzi ababandakanyekayo ekugcinweni kwe-flange ngokubambisana kubalulekile ekuqinisekiseni amalunga anamandla kwaye athembekileyo. Abasebenzi kufuneka baqeqeshwe kwiindlela ezifanelekileyo zokufakela, amaxabiso torque, kunye nezenzo zokulondoloza ukuqinisekisa ukuba ii-flange joints zigcinwa ngokufanelekileyo.
Kuko konke, iindlela zogcino olululo zibalulekile ekugcineni amalungu eflange aqinileyo kwaye athembekileyo. Ukuhlolwa rhoqo, ukugcinwa, kunye noqeqesho lunokunceda ukuthintela ukuvuza, umhlwa, okanye eminye imiba ebeka esichengeni imfezeko edibeneyo.
Ukuququmbela, ukuqonda iziseko ze-flange joints kubalulekile ekuqinisekiseni ukusebenza kwazo kunye nokuthembeka kwizicelo zoshishino. Uyilo olufanelekileyo, ukhetho lwezinto eziphathekayo, iindlela zokufakela, kunye nezenzo zokugcinwa kwayo yonke imiba ebalulekileyo yokudala amalungu e-flange aqinileyo kwaye athembekileyo. Ngokuthathela ingqalelo le miba ngononophelo nokulandela ezona ndlela zilungileyo zolondolozo, kunokwenzeka ukudala amajoyina e-flange anikezela ukusebenza kwexesha elide kunye nokuthembeka kwiinkqubo zoshishino.
