Umenzi kunye neMeko
Imibhobho yentsimbi ye-ASTM A213 T12 mayiyenziwe ngenkqubo engenamthungo kwaye mayigqitywe ngokushisa okanye ngokubandayo, njengoko kuchaziwe.
Unyango lobushushu
Zonke iipayipi zentsimbi ze-T12 ziya kunyangwa ngobushushu.
Iindlela zonyango lobushushu ezivumelekileyo ziquka u-fukucoca okungcolileyo okanye okushushu, ukulungisa kunye nokulungisaokanyeukufakelwa kwe-subcritical.

| Uvavanyo lokuTyatya | Uvavanyo olunye lokuthamba kufuneka lwenziwe kwiisampuli ezivela kwisiphelo ngasinye setyhubhu enye egqityiweyo, kungekhona leyo isetyenziselwa uvavanyo lokuthamba, ukusuka kwiqashiso ngalinye. | |
| Uvavanyo lokuvutha | Uvavanyo olunye lokutshaya kufuneka lwenziwe kwiisampuli ezivela kwisiphelo ngasinye setyhubhu enye egqityiweyo, kungekhona leyo isetyenziselwa uvavanyo lokutshaya, ukusuka kwilothi nganye. | |
Ityhubhu nganye kufuneka ivavanywe ngombane ongonakalisiyo okanye uvavanyo lwe-hydrostatic.Uhlobo lovavanyo oluza kusetyenziswa luza kukhethwa ngumvelisi, ngaphandle kokuba kuchazwe ngenye indlela kwi-odolo yokuthenga.
Iindlela zovavanyo kufuneka zenziwe ngokuhambelana neemfuno ezifanelekileyo zeCandelo 25 kunye nelama-26 le-ASTM A1016.
Ubukhulu beetyhubhu ze-ASTM A213 T12 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-T12 nazo zinokubonelelwa, ukuba nje zonke ezinye iimfuno ze-ASTM A213 ziyafezekiswa.
Iityhubhu zentsimbi ye-ASTM A213 T12 ezingenamthungo zisetyenziswa kakhulu kwiindawo zenkonzo ezinobushushu obuphezulu kunye noxinzelelo oluphezulu.
1. IiSuperheaters kunye neeReheaters

3. Izitshintshi zobushushu
Ifanelekile kwiityhubhu zokutshintshiselana nobushushu kwimizi-mveliso ye-petrochemical kunye neyekhemikhali ngenxa yokumelana kwayo kakuhle nokuqhekeka kunye nozinzo lobushushu.
4. Iityhubhu zeFurnace kunye neHeater
Ifakwe kwiikhoyili ze-furnacery zokucocisa, iityhubhu ze-heater, kunye nee-process heater apho kufuneka khona ukumelana ne-oxidation kunye namandla exesha elide.
5. Iipayipi zoxinzelelo kwizityalo zamandla kunye neekhemikhali
Isetyenziselwa imibhobho enobushushu obuphezulu, kuquka imibhobho yomphunga kunye nemibhobho yokuthutha ulwelo olushushu.
