Ukuphucula rhoqo inkqubo yolawulo ngenxa yomgaqo othi "ukunyaniseka, ukholo olulungileyo kunye nomgangatho zisisiseko sophuhliso lweshishini", sithatha ngokubanzi isiseko seemveliso ezinxulumene namazwe ngamazwe, kwaye sihlala siphuhlisa iimveliso ezintsha ukuhlangabezana neemfuno zabathengi abadumileyo. Uyilo lwe-China ASTM/ASME A335/SA335 P91 Umbhobho weCarbon Steel engenamthungo/Ibhoyibhu yeBoiler yeNkonzo yoBubushushu obuphezulu, ngoku sine-inventory enkulu yokuzalisekisa iifowuni kunye neemfuno zabathengi bethu.
Ukuphucula rhoqo inkqubo yolawulo ngenxa yomgaqo othi "ukunyaniseka, ukholo olulungileyo kunye nomgangatho zisisiseko sophuhliso lweshishini", sithatha ngokubanzi isiseko seemveliso ezinxulumene namazwe ngamazwe, kwaye sihlala siphuhlisa iimveliso ezintsha ukuhlangabezana neemfuno zabathengi.Umbhobho weBoiler waseTshayina, ityhubhu yentsimbi engenamthungo, Ukuba ufuna nayiphi na imveliso yethu, okanye unezinye izinto eziza kuveliswa, nceda usithumelele imibuzo yakho, iisampuli okanye imidwebo eneenkcukacha. Ngeli xesha, sijonge ukuphuhlisa sibe liqela leshishini lamazwe ngamazwe, sijonge phambili ekufumaneni izibonelelo zamaphulo adibeneyo kunye nezinye iiprojekthi zentsebenziswano.
Isishwankathelo
Isicelo
Isetyenziswa ikakhulu ukwenza umgangatho ophezulu wekhabhoni yentsimbi, umbhobho webhoyila woxinzelelo oluphantsi, umbhobho oshushu oshushu kakhulu ongenamthungo wecarbon.
IBanga eliPhambili

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.
