Umbhobho wentsimbi yepetroleum luhlobo lwentsimbi ende enecandelo elinomgongxo kwaye akukho hlanganiso ejikelezileyo, ngelixa umbhobho wokuqhekeka wepetroleum luhlobo lwecandelo lezoqoqosho. ishaft, isakhelo sebhayisekile kunye nesikafula sentsimbi esisetyenziswa ekwakhiweni, njl njl. Ukusebenzisa ityhubhu yokuqhekeka kwepetroleum ukwenza iinxalenye zamakhonkco kunokuphucula umgangatho wokusetyenziswa kwezinto, ukwenza lula inkqubo yokuvelisa, ukonga izinto kunye nexesha lokucubungula, njengeringi yokuthwala, umkhono wejack, njl. isetyenziswe ngokubanzi ukwenza umbhobho wentsimbi. Iityhubhu yokuqhekeka yepetroli okanye iintlobo ngeentlobo zezixhobo zesiqhelo eziyimfuneko, umgqomo, umgqomo njalo njalo kwityhubhu yokuqhekeka yepetroleum ukwenza. imilo yendawo ye-cross-sectional.Njengoko indawo ye-petroleum yokuqhekeka ipayipi iyona inkulu kunye ne-perimeter efanayo, i-fluid eninzi inokuthuthwa ngombhobho ojikelezayo.

I-API 5CT ihlukaniswe kwi-K55, N80, L80, P110 kunye namanye amabakala ensimbi.

I-Tubing J55 (37Mn5)

I-Casing J55 (37Mn5)

Umbhobho wokudibanisa i-J55 (37Mn5)

Ipayipi yensimbi ye-petroleum (i-GB/T9948-88) yipayipi yensimbi engenamthungo efanelekileyo kwi-tube yesithando somlilo, umtshintshi wokushisa kunye nombhobho kwi-petroleum refinery.

Umbhobho wentsimbi wokomba wejoloji (YB235-70) usetyenziselwa ukugrumba okungundoqo lisebe le-geological, elinokwahlulwa libe ngumbhobho wokubhobhoza, ikhola yokubhola, umbhobho ongundoqo, umbhobho we-casing kunye nombhobho wemvula ngokokusetyenziswa kwayo.
