Izinto zethu zentengiso ziqhelekile kwaye zithembeke ngabathengi kwaye zinokudibana rhoqo nokuphuhlisa iminqweno yezoqoqosho nentlalontleUmbhobho wentsimbi waseTshayina ongenamthungo kunye neTube yentsimbi engenamthungo, Ngethuba leminyaka emifutshane, sikhonza abathengi bethu ngokunyanisekileyo njengoMgangatho wokuQala, uBulunga beNgqibelelo, ukuhanjiswa kwangexesha, okuye kwasenzela ukuba sibe nodumo olubalaseleyo kunye nepotifoliyo yokhathalelo lomxumi. Ndijonge phambili ekusebenzeni nawe Ngoku!
Isishwankathelo
Isicelo
Isetyenziswa ikakhulu ukwenza umgangatho ophezulu wekhabhoni yentsimbi, umbhobho webhoyila woxinzelelo oluphantsi, umbhobho oshushu oshushu kakhulu ongenamthungo wecarbon.
IBanga eliPhambili
Ibakala eliphezulu carbon yesakhiwo steel: 10 #,20 #

Imfuneko yoVavanyo
Uvavanyo lokucaba
Iityhubhu zentsimbi ezinobubanzi obungaphezulu kwe-22 mm ukuya kutsho kwi-400 mm, kunye nobukhulu bodonga obungaphezulu kwe-10 mm kufuneka zenze uvavanyo lokucaba. Emva kokuba iisampulu zityatyekwe
Ukugoba uvavanyo
Iityhubhu zentsimbi ezinobubanzi obungaphandle obungekho ngaphezulu kwe-22 mm kufuneka zingene kuvavanyo lokugoba. I-engile yokugoba yi-90o. I-radius yokugoba ngamaxesha angama-6 ububanzi bangaphandle bombhobho wensimbi.Emva kokugoba isampuli, akukho kuphazamiseka okanye ukuqhekeka kuvunyelwe ukuba kubonakale kwisampuli.
Uviwo lweMacroscopic
Kwiityhubhu zentsimbi ezenziwe ngokuthe gqolo ngokuphoswa kweebhilidi okanye ii-ingots zentsimbi, iqela elinikezelayo kufuneka liqinisekise ukuba akukho mabala amhlophe, ukungcola, amaqamza omoya angaphantsi komhlaba, amabala okakayi okanye ukwaleka kwi-asidi evutshiweyo ye-macroscopic tissue ye-billet okanye ityhubhu yentsimbi.
Ukuhlolwa okungonakalisi
Ngokwesicelo seqela elifunayo, elithe ke lixoxisana phakathi kwamaqela anikezelayo kunye nalawo afunayo kwaye aboniswe kwisivumelwano, ukufumanisa impazamo ye-ultrasonic inokwenziwa ngabanye kwiityhubhu zetsimbi. I-longitudinal manual defect ye-tube yesampuli yereferensi kufuneka ihlangabezane neemfuno zokwamkelwa emva kokuhlolwa kwebakala C8 elichazwe kwi-GB / T 5777-1996.
