Umenzi kunye neMeko
Imibhobho yentsimbi ye-ASTM A213 T5 mayiyenziwe yiinkqubo engenamthungokwaye kufuneka igqitywe ngokushushu okanye ngokubandayo, njengoko kuchaziwe.
Unyango lobushushu
Imibhobho yentsimbi ye-T5 kufuneka ifudunyezwe ukuze ifudunyezwe ngokweendlela ezilandelayo, kwaye unyango lobushushu kufuneka lwenziwe ngokwahlukeneyo kwaye ukongeza ekufudunyezweni ukuze kwenziwe ubushushu.

Ezinye ziyaqina emoyeni, oko kukuthi, ziqina ukuya kwinqanaba elingafunekiyo xa zipholiswa kwi-ạir ngenxa yobushushu obuphezulu, ingakumbi iintsimbi ezine-chromium ezine-chromium eyi-4% nangaphezulu. Ke ngoko, imisebenzi ebandakanya ukufudumeza ezo ntsimbi ngaphezu kobushushu bazo obubalulekileyo, njengokuwelda, ukuflanga, kunye nokugoba okushushu. kufuneka kulandelwe lunyango olufanelekileyo lobushushu.
Inkangeleko
Iityhubhu zentsimbi ezigqityiweyo ze-ASTM A213 ferritic alloy ezibandayo mazingabi nazikali kwaye zilungele ukuhlolwa. Ubungakanani obuncinci be-oxidation abuthathwa njengobukhulu.
Iityhubhu zentsimbi ezigqityiweyo nge-ferritic alloy ezishushu mazingabi nazikali zikhululekileyo kwaye zilungele ukuhlolwa.
Ubukhulu
Ubukhulu beetyhubhu ze-ASTM A213 T11 kunye nobukhulu bodonga zihlala zixhotyiswe ngobubanzi bangaphakathi obuqala kwi-3.2 mm ukuya kububanzi bangaphandle obuyi-127 mm, kunye nobukhulu bodonga obuncinci obuqala kwi-0.4 mm ukuya kwi-12.7 mm.
Ezinye iisayizi zeepayipi zentsimbi ze-T11 nazo zinokubonelelwa, ukuba nje zonke ezinye iimfuno ze-ASTM A213 ziyafezekiswa.
Ityhubhu nganye iya kwenziwa uvavanyo lombane olungatshabalalisiyo okanye uvavanyo lwe-hydrostatic. Uhlobo lovavanyo oluza kusetyenziswa luya kuba lolwenziwa ngumvelisi, ngaphandle kokuba kuchazwe ngenye indlela kwi-odolo yokuthenga.
Umgangatho we-ASTM A1016 uvumela ukusetyenziswa kovavanyo olungonakalisiyo endaweni yovavanyo lwe-hydrostatic.
Iipayipi zentsimbi ezingenamthungo ze-ASTM A213 T5 alloy zisetyenziswa kakhulu kwizicelo zoshishino phantsi kweemeko zobushushu obuphezulu kunye noxinzelelo oluphezulu, kunye nokusebenza okuphawulekayo kwimizi-mveliso yokuvelisa umbane, iikhemikhali, kunye neoyile kunye negesi.
Izicelo eziqhelekileyo ziqukaiityhubhu zebhoyila, iityhubhu zokutshintshiselana nobushushu, iipayipi zenkqubo yeekhemikhali, izixhobo zebhoyila kunye neenqanawa zoxinzelelo, kunye neepayipi zokuthutha igesi kubushushu obuphezulu.
