Monga tonse tikudziwa, mafuta amafuta amayeretsedwa kuchokera ku petroleum. Mtengo wa petroleum ukukwera m'zaka zino, ndipo mtengo wagalimoto ukukulirakulira. Pochotsa mafuta, mapaipi ambiri amafunika kuikidwa.

Nazi kuyang'ana mapaipi:

Tubing (GB9948-88) ndi chubu chachitsulo chopanda msoko yoyenera ng'anjo ya ng'anjo, 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.

Chitoliro chamafuta ndi mtundu wachitsulo chachitali chokhala ndi gawo lopanda kanthu ndipo palibe cholumikizira mozungulira, pomwe chitoliro chophwanyidwa chamafuta ndi mtundu wachitsulo chagawo lazachuma.

Ma chubu amagwiritsidwa ntchito kwambiri popanga zida zamakina komanso zamakina monga mapaipi obowola mafuta, ma shaft oyendetsa galimoto, mafelemu a njinga ndi zitsulo zopangira zithunzi zosuntha pomanga. Kugwiritsa ntchito mafuta osokoneza chubu kupanga mbali mphete akhoza kusintha mlingo magwiritsidwe ntchito, kufewetsa ndondomeko kupanga, kupulumutsa zinthu ndi processing nthawi, monga anagubuduza kubala mphete, Jack sleeve, etc., wakhala ankagwiritsa ntchito popanga zitsulo chitoliro. Mafuta ophulika chubu kapena zida zosiyanasiyana wamba zofunika kwambiri, mbiya, mbiya ndi zina zotero kuti mafuta akulimbana chubu kupanga. Mafuta osokoneza chitoliro akhoza kugawidwa mu chitoliro chozungulira ndi chitoliro chapadera chofanana ndi mawonekedwe a malo ozungulira. Popeza dera la mafuta osokoneza chitoliro ndi lalikulu kwambiri ndi lozungulira lomwelo, madzi ambiri amatha kunyamulidwa ndi chitoliro chozungulira.

Mtengo wa API5CTchosungira mafuta chimagwiritsidwa ntchito makamaka kunyamula mafuta, gasi, gasi, madzi ndi zakumwa zina ndi mpweya.

Iwo akhoza kugawidwa mu seamless zitsulo chitoliro ndi welded zitsulo chitoliro. Chitoliro chachitsulo chowotcherera makamaka chimatanthawuza chitoliro chachitsulo chowongoka, ndipo chotengera chachikulu chamafuta amafuta nthawi zambiri chimakhala chitoliro chowongoka chomira pansi pa arc. Mayiko akuluakulu ogwiritsira ntchito mankhwalawa amagawidwa makamaka ku Middle East, Europe ndi America.Api5ctcasing akhoza kugawidwa mu R-1, R-2 ndi R-3 specifications malinga ndi kutalika. Zida zazikulu ndi B, X42, X46, X56, X65, X70 ndi zina zotero. Pakutentha kwambiri komanso malo oponderezedwa kwambiri, mapaipi amafuta a petroleum casing ali ndi zabwino zake zapadera. Kupaka mafuta a Api5ct kuchokera kuzinthu zopangira kupita kuzinthu musanapereke mayeso okhazikika, kuyesa kwamphamvu, kuyesa kwamphamvu, kuyesa kwamphamvu ndi zina zofananira.
