Petroleum zitsulo chitoliro ndi mtundu wa zitsulo yaitali ndi gawo dzenje ndipo palibe olowa mozungulira, pamene mafuta osokoneza chitoliro ndi mtundu wa chuma gawo chuma steel.Role: chimagwiritsidwa ntchito popanga mbali structural ndi makina, monga chitoliro kubowola mafuta, galimoto galimoto. kutsinde, njinga chimango ndi zitsulo scaffolding ntchito pomanga, etc. Kugwiritsa ntchito mafuta osokoneza chubu kupanga mbali mphete akhoza kusintha zinthu mlingo magwiritsidwe ntchito, kuphweka kupanga ndondomeko, kupulumutsa zinthu ndi processing nthawi, monga anagubuduza kubala mphete, jack sleeve, etc., ali akhala ankagwiritsa ntchito popanga zitsulo chitoliro.Petroleum akulimbana chubu kapena mitundu yosiyanasiyana ya zida ochiritsira chofunika kwambiri, mbiya, mbiya ndi zina zotero kuti mafuta osokoneza chubu kupanga.Petroleum akulimbana chitoliro akhoza kugawidwa mu chitoliro chozungulira ndi chitoliro chapadera-zoboola pakati malinga ndi mawonekedwe a cross-Sectional area.Popeza dera la mafuta osokoneza chitoliro ndi lalikulu kwambiri ndi lozungulira lomwelo, madzi ambiri amatha kunyamulidwa ndi chitoliro chozungulira.

API 5CT lagawidwa K55, N80, L80, P110 ndi zina zitsulo.

Chitoliro chachitsulo cha Petroleum (GB/T9948-88) ndi chitoliro chachitsulo chosasokonezeka choyenera ng'anjo yamoto, chotenthetsera kutentha ndi payipi mumafuta opangira mafuta.

Chitoliro chachitsulo cha pobowola geological (YB235-70) chimagwiritsidwa ntchito pobowola pachimake ndi dipatimenti ya geological, yomwe imatha kugawidwa mu chitoliro chobowola, kolala yobowola, chitoliro chapakati, chitoliro cha casing ndi chitoliro cha mpweya malinga ndi ntchito yake.
