I-petroleum kunye nezinto zepetrochemical zinokwahlulwa zibe yintsimbi ye-carbon structural, i-alloy iron ephantsi, i-alloy steel high, i-nickel-based alloy, i-iron alloy copper alloy, i-aluminium alloy, i-metal composite materials, i-non-metal composite materials kunye nezinye izinto ngokuhambelana nezinto; ngokwemilo egqityiweyo Ikwahlulahlulwe ngamacwecwe kunye nemibhobho, iipleyiti ezidibeneyo / iityhubhu, iiprofayili, iintonga kunye neengcingo, i-castings kunye ne-forgings kunye nezixhobo zokudibanisa (izinto zokudibanisa, iiflanges, izixhobo zombhobho), njl.; ngokwemeko yokwenziwa kwezinto, inokwahlulwa ibe yi-hot rolling, extrusion, drawing, treatment heat, Casting, forging, mechanical composite, composite eqhumayo, i-rolling composite, i-surfacing composite kunye nezinye iintlobo; ngokwentsimi yesicelo, inokwahlulwa kwizinto zobunjineli be-wellbore, izinto zobunjineli bomhlaba, ukucokisa izinto zekhemikhali, izixhobo zoomatshini bepetroleum kunye nezixhobo zaselwandle Izinto zobunjineli, njl. Njengoko umfanekiso ubonisa:
