I-Flangeukhetho kufuneka luhlangabezane neemfuno zoyilo.Xa uyilo alufuni, kufuneka luhambelane nenkqubo yoxinzelelo oluphezulu, ubushushu obuphezulu bokusebenza, indawo yokusebenza,iflangeibakala lemathiriyeli kunye neminye imiba yokhetho olubanzi lwefomu efanelekileyo kunye neenkcukacha zeflange.
I-Flangekufuneka ihlolwe phambi kofakelo, umphezulu kufuneka ugudiswe, kungabikho mingxunya yesanti, iintanda, amabala, i-burrs kunye nezinye iziphene ezinciphisa amandla e-flange, kwaye kungabikho mikrwelo yokungena kunye nezinye iziphene ezichaphazela ukutywinwa kwi-flange. indawo yokutywina.
Xa kuhlanganiswaiiflangekunye nemibhobho, sebenzisa irula yeflange ukujonga ukuthe tye kweiiflange.Xa iiflangeuxhulumaniso ubungakanani ukutenxa ngokuhambelanayo ayichazwanga kuyilo, akufanele ibe mkhulu kune-1, 5% ye-flange ububanzi, kwaye kungabi ngaphezu kwe-2mm, xa iiflange ezimbini zingahambelani kwaye zigqithise iimfuno zenkcazo kufuneka zilungiswe, musa ukusebenzisa iigasket ezininzi ukulungisa.
Xa iiflangeidityaniswe kumbhobho, kufuneka idityaniswe kumacala omabini ngokomgangatho, kwaye ukuphakama konyawo lwe-welding kufuneka kuhlangabezane neemfuno.
