Imibhobho yentsimbi engenamthungo yimveliso ebalulekileyo yentsimbi isetyenziswe ngokubanzi kwiindawo ezininzi. Inkqubo yayo yokwenza eyahlukileyo yenza umbhobho wentsimbi ngaphandle kwe-wels, eneepropathi ezingcono zoomatshini kunye nokuxhathisa ngokunyanzelekileyo, kufanelekile ukuba iimeko zinoxinzelelo oluphezulu kunye nobushushu obuphezulu.

Ngokwemeko yokusetyenziswa, imibhobho yentsimbi engenamthungo idla ngokusetyenziswa kwimihlaba efana ne-oyile kunye ne-IgesiSokuthuthswa, umzi-mveliso wekhemikhali, ukwakhiwa kweshishini kunye neshishini lezomzi-mveliso kunye nemveliso yemoto. Ingakumbi kumzi-mveliso we-oyile kunye negesi, imibhobho yentsimbi engenamthungo ihlala isetyenziselwa imibhobho kunye nezixhobo ze-Downshole, kwaye zinokumelana neemeko zemo engqongileyo.

Ngokuphathelele imigangatho, imibhobho yentsimbi engenamthungo ihlala iveliswa kwaye ivavanywe ngokungqinelana nemigangatho yesizwe (njenge-GB, i-ASTM, i-API, njl njl).I-GB / T 8162isebenza kwimibhobho yentsimbi engenamthungo yezakhiwo, ngelixaI-ASTM A106isetyenziselwa ikakhulu kwimibhobho ye-carbon yentsimbi engenamthungo kwinkonzo yobushushu obuphezulu. Kwimibhobho yentsimbi ye-aly ye-laly, imigangatho eqhelekileyo ibandakanyaI-ASTM A335, kwaye amabandakanye amele i-P5 kunye ne-P9 ukuqinisekisa ukusebenza kwemibhobho yentsimbi kubushushu obuthile kunye noxinzelelo.

Ngokwezixhobo, imibhobho yentsimbi engenamthungo ihlala isebenzisa i-alloy ephantsi kunye ne-allous yesabelo esiphezulu, kunye nokunganyangeki kwe-corrosion egqwesileyo, ukumelana nobushushu obuphezulu kunye nokunganyangeki kweqondo lobushushu kunye nokuchaswa kwe-oxidation. Umzekelo, izixhobo ezisetyenziswa ngokuqhelekileyo kwimibhobho yentsimbi ye-Alloy ibandakanya i-cr-mo alloy yentsimbi (njenge-12cct.), Ezilungele ubushushu obuphezulu kunye nezixhobo ezinoxinzelelo oluphezulu. Ezi zixhobo zisebenza ngonyango olunobushushu kunye nokuhlolwa ukuqinisekisa uzinzo nokhuseleko lwazo phantsi kweemeko ezigqithisileyo.

Imibhobho yentsimbi engenamthungo, ngakumbi imibhobho yentsimbi engenamthungo, idlala indima ebalulekileyo kwishishini lanamhlanje. Imveliso yabo emiselweyo kunye nezinto eziphezulu zenza ukuba kuthathwe ukhetho olufanelekileyo lwezicelo ezahlukeneyo zobunjineli.
