Umbhobho wensimbi ongenamthungo yimveliso yentsimbi ebalulekileyo esetyenziswa ngokubanzi kwiinkalo ezininzi. Inkqubo yayo ekhethekileyo yokuvelisa yenza umbhobho wensimbi ngaphandle kwe-welds, eneempawu ezingcono zomatshini kunye nokumelana noxinzelelo, ezifanelekileyo kwiindawo ezinoxinzelelo oluphezulu kunye nokushisa okuphezulu.
Ngokwemeko yokusetyenziswa, imibhobho yentsimbi engenamthungo isetyenziswa ngokuqhelekileyo kwimimandla efana nokuthuthwa kweoli kunye negesi, ishishini lemichiza, ulwakhiwo, ukwakhiwa kweenqanawa kunye noshishino lwemoto. Ngokukodwa kwishishini leoli kunye negesi, imibhobho yentsimbi engenamthungo isoloko isetyenziselwa imibhobho kunye nezixhobo zokuhla, kwaye inokumelana neemeko ezinzima zokusingqongileyo.
Ngokumalunga nemigangatho, iipayipi zensimbi ezingenamthungo zivame ukuveliswa kwaye zivavanywe ngokuhambelana nemigangatho yelizwe (njenge-GB, ASTM, API, njl.).GB/T 8162iyasebenza kwimibhobho yentsimbi engenamthungo yezakhiwo, ngelixaI-ASTM A106ikakhulu isetyenziselwa carbon steel imibhobho ingenamthungo kwinkonzo yobushushu obuphezulu. Kwimibhobho yensimbi engenamthungo, imigangatho eqhelekileyo ibandakanyaI-ASTM A335, kunye namabakala amele i-P5 kunye ne-P9 ukuqinisekisa ukusebenza kweepayipi zetsimbi kumaqondo okushisa athile kunye noxinzelelo.
Ngokubhekiselele kwizinto eziphathekayo, iibhobho zentsimbi ezingenamthungo zihlala zisebenzisa i-alloy ephantsi kunye neentsimbi eziphezulu ze-alloy, ezinokumelana ne-corrosion egqwesileyo, ukumelana nobushushu obuphezulu kunye nokumelana ne-oxidation. Ngokomzekelo, izinto ezisetyenziswa ngokuqhelekileyo kwimibhobho yensimbi ye-alloy ziquka i-Cr-Mo insimbi ye-alloy (efana ne-12Cr1MoG njl.), ezifanelekileyo kwi-high-temperature kunye nezixhobo eziphezulu zoxinzelelo ezifana neebhoyili kunye nokutshintshana kobushushu. Ezi zixhobo ziphantsi konyango olushushu kunye nokuhlolwa ukuqinisekisa ukuzinza kunye nokhuseleko phantsi kweemeko ezinzima.
Imibhobho yentsimbi engenamthungo, ngakumbi imibhobho yentsimbi engenamthungo, idlala indima ebalulekileyo kushishino lwanamhlanje. Imveliso yabo esemgangathweni kunye nezixhobo eziphezulu zibenza babe lolona khetho lufanelekileyo kwizicelo zobunjineli ezahlukeneyo.
