Flange alxanka dabada ma fududa in la qaabeeyo, si fiican loo shaabadeeyey, si weyn loo isticmaalo, ayaa u dhiganta qallafsanaanta iyo shuruudaha barti iyo kala guurka khafiifinta dabada alxanka macquulka ah, masaafada alxanka ee dusha wadajirka ah waa weyn, dusha wadajirka ah ka soo alxanka qallafsanaanta heerkulka, waxa ay qaadataa wax ka badan. Qaab dhismeedka jirka ee qufaca adag, oo ku habboon cadaadiska ama isbeddelka heerkulka dhuumaha ama heerkulka sare, cadaadiska sare iyo tuubada heerkulka hooseeya, Guud ahaan loo isticmaalo PN ka weyn tuubada 2.5MPa iyo isku xirka valve;Waxa kale oo loo isticmaalaa in lagu qaado dhuumaha dhexdhexaadka ah ee qaaliga ah, guban kara, walxaha qarxa.
Dabada alxanka leh waxaa guud ahaan lagu sameeyaa foorjarin ama habsocod.Marka saxanka birta ama qaybta birta la isticmaalo, shuruudaha soo socda waa in la buuxiyaa:
1.The flange alxanka dabada waa in lagu baaro ultrasonic, iyada oo aan cilladaha delamination;
2. Waa in la gooyaa xariijimo dhinaca jihada birta loo rogo, lagu dhufto giraan iyada oo foorarsi ah, iyo dusha birta si ay u sameeyaan dhululubo giraanta.Saxanka birta ah waa inaan si toos ah loogu farsamayn alxanka dabada qoorta;
3.Alxanka dabada ee giraanta waa in ay qaataan alxanka lays buuxa;
4. Dabada dabada ee giraanta waa in la mariyaa daaweynta kulaylka ka dib alxanka, waxaana lagu sammeeyaa 100% ray ama kormeerka ultrasonic, kaas oo buuxin doona shuruudaha II ee JB4730 iyo kormeerka ultrasonic waa inuu buuxiyaa shuruudaha I ee JB4730.
Jiirada qoorta sare ee flange alxanka dabada waa inuusan ka badnaan 70°.Xuduudaha farsamada ee flange alxanka dabada si adag ayaa loo xakameeyaa inta lagu jiro wax soo saarka iyo alxanka si loo hubiyo in ay ka ciyaari karto doorkeeda iyo qiimaha si buuxda wax soo saarka iyo isticmaalka.
