Umbhobho wentsimbi ongenamthungo yimveliso ebalulekileyo yentsimbi esetyenziswa kakhulu kwiindawo ezininzi. Inkqubo yawo yokuvelisa eyahlukileyo yenza umbhobho wentsimbi ungabi nazi-welds, oneempawu ezingcono zoomatshini kunye nokumelana nokucinezelwa, ulungele iindawo ezinoxinzelelo oluphezulu kunye nobushushu obuphezulu.

Ngokuphathelele iimeko zokusetyenziswa, imibhobho yentsimbi engenamthungo isetyenziswa kakhulu kwiindawo ezifana nokuthuthwa kweoyile negesi, ishishini leekhemikhali, ulwakhiwo, ukwakhiwa kweenqanawa kunye neshishini leemoto. Ingakumbi kwishishini leoyile negesi, imibhobho yentsimbi engenamthungo idla ngokusetyenziselwa imibhobho kunye nezixhobo zokufaka umngxuma, kwaye inokumelana neemeko ezinzima zokusingqongileyo.

Ngokuphathelele imigangatho, imibhobho yentsimbi engenamthungo idla ngokuveliswa kwaye ivavanywe ngokwemigangatho yesizwe (efana ne-GB, i-ASTM, i-API, njl.njl.).GB/T 8162iyasebenza kwimibhobho yentsimbi engenamthungo kwizakhiwo, ngelixaI-ASTM A106isetyenziswa kakhulu kwiipayipi ezingenamthungo zentsimbi yekhabhoni ukuze kusetyenziswe ubushushu obuphezulu. Kwiipayipi zentsimbi ezingenamthungo ze-alloy, imigangatho eqhelekileyo ibandakanyaI-ASTM A335, kwaye amanqanaba ameleyo yi-P5 kunye ne-P9 ukuqinisekisa ukusebenza kwemibhobho yentsimbi kumaqondo obushushu athile kunye noxinzelelo.

Ngokuphathelele izinto ezisetyenziswayo, imibhobho yentsimbi engenamthungo ye-alloy idla ngokusebenzisa iintsimbi ze-alloy eziphantsi kunye ne-alloy ephezulu, ezinokumelana okuhle nokugqwala, ukumelana nobushushu obuphezulu kunye nokumelana ne-oxidation. Umzekelo, izinto ezisetyenziswa rhoqo kwimibhobho yentsimbi ye-alloy ziquka intsimbi ye-alloy ye-Cr-Mo (efana ne-12Cr1MoG njl.njl.), ezifanelekileyo kwizixhobo ezisebenzisa ubushushu obuphezulu kunye noxinzelelo oluphezulu ezifana neebhoyila kunye nezitshintshi zobushushu. Ezi zinto ziphathwa ngobushushu obuqatha kwaye zihlolwa ukuqinisekisa uzinzo kunye nokhuseleko lwazo phantsi kweemeko ezinzima.

Iipayipi zentsimbi ezingenamthungo, ingakumbi iipayipi zentsimbi engenamthungo, zidlala indima ebalulekileyo kushishino lwanamhlanje. Imveliso yazo esemgangathweni kunye nezixhobo ezisemgangathweni zizenza zibe lukhetho olufanelekileyo kwiintlobo ngeentlobo zezicelo zobunjineli.
