Ipayipi lensimbi kaphethiloli uhlobo lwensimbi ende enengxenye engenalutho futhi engenalo ijoyinti elizungezile, kuyilapho ipayipi lokuqhekeka kwe-petroleum uhlobo lwensimbi yengxenye yezomnotho. Indima: isetshenziswa kabanzi ekwakhiweni kwezingxenye zesakhiwo nezemishini, njengepayipi lokubhoboza uwoyela, umgodi wokushayela imoto, uhlaka lwebhayisikili kanye ne-scaffolding yensimbi esetshenziswa ekwakheni, njll. Ukusebenzisa ipayipi lokuqhekeka kwe-petroleum ukukhiqiza izingxenye zendandatho kungathuthukisa izinga lokusetshenziswa kwezinto, kube lula inqubo yokukhiqiza, konge izinto kanye nesikhathi sokucubungula, njengendandatho yokuthwala egoqayo, i-jack sleeve, njll., isetshenziswe kabanzi ekwakhiweni kwepayipi lensimbi. Ipayipi lokuqhekeka kwe-petroleum noma izikhali ezahlukahlukene ezivamile, i-barrel, i-barrel nokunye, ipayipi lokuqhekeka kwe-petroleum lingahlukaniswa libe yipayipi eliyindilinga kanye nepayipi elinomumo okhethekile ngokuya ngesimo sendawo enqamulayo. Njengoba indawo yepayipi lokuqhekeka kwe-petroleum inkulu kakhulu enomngcele ofanayo, uketshezi oluningi lungathuthwa ngepayipi eliyindilinga.

I-API 5CT ihlukaniswe ngama-K55, N80, L80, P110 kanye nezinye izinhlobo zensimbi.

Ipayipi J55 (37Mn5)

Ibhokisi J55 (37Mn5)

Ipayipi lokuxhumanisa i-J55 (37Mn5)

Ipayipi lensimbi ye-Petroleum (GB/T9948-88) lipayipi lensimbi elingenamthungo elifanelekela ipayipi lesithando, i-heat exchanger kanye nepayipi endaweni yokuhluza i-petroleum.

Ipayipi lensimbi lokubhoboza i-geological (YB235-70) lisetshenziselwa ukubhoboza i-core ngumnyango we-geological, elingahlukaniswa ngepayipi lokubhoboza, ikhola yokubhoboza, ipayipi eliyinhloko, ipayipi le-casing kanye nepayipi lokupholisa ngokwendlela elisetshenziswa ngayo.
