Shuruudaha farsamada eebeen-abuurka tubooyinka flange(oo ay ku jiraanbeen abuur ahiyoqaybo duuban).
1.Darajada iyo shuruudaha farsamada eebeen abuurasho(oo ay ku jiraanla been abuurtay oo duuban) waa inuu buuxiyaa shuruudaha u dhigma ee JB4726-4728.
2.Cadaadiska magacaaban PN 0.25 MP 1.0 MPa birta kaarboon iyo austenitic ahamafoornada birta ahla oggolaaday isticmaalka heerka Ⅰ foornada.
3.Qodobada soo socda ka sokow, cadaadiska magaca ah ee PN 1.6 MPa ilaa 6.3 MPa been-abuurka waa in ay u hoggaansamaan heerka Ⅱ ama heerka ka sarreeya Ⅱheerarka been-abuurka.
4.Mid ka mid ah kuwan soo socda waa inuu waafaqsan yahay shuruudaha Ⅲ iyobeen abuurasho: (1) cadaadiska magaca PN acuity 10.0 MPafoornada flange;(2) chromium-molybdenumfoornada birta ahoo leh cadaadis magaceed PN> 4.0MPa; (3) ferriticfoornada birta ahcadaadiska magaca PN> 1.6MPa iyo heerkulka hawlgalka ≤-20 ℃.

Dabadaalxanka qoorta, alxanka siman qoorta, alxanka godkaiyodhuuban duntawaxaa guud ahaan lagu sameeyaa been abuur amarogrogidMarka saxanka birta ama qaybta birta la isticmaalo, shuruudaha soo socda waa in la buuxiyaa:
1.Saxanka birta ah waa in lagu eego ultrasonic iyada oo aan cillad lahayn;
2.Waa in la googooyaa xariijimo ay la socdaan jihada rogrogidda ee birta, oo lagu alxamaa giraanta iyadoo foorarsanaysa, oo ka dhigaysa dusha birta inay noqoto dhululubo giraanta.lugaha leh qoorta;
3.Alxanka galitaanka buuxa waa in loo qaataa alxanka dabada ee giraanta;
4.Alxanka dabada ee giraanta waa in la mariyaa daawaynta kulaylka ka dib oo waxay fulisaa 100% raajada ama ogaanshaha cilladda ultrasonic, ogaanshaha cilladda raajada waa inay buuxisaa shuruudaha fasalka II ee JB4730 iyo ogaanshaha cilladda ultrasonic waa inay buuxisaa fasalka I. shuruudaha JB4730.
