Ipayipi lensimbi likaphethiloli liwuhlobo lwensimbi ende enengxenye engenalutho futhi alihlanganisi nxazonke, kuyilapho ipayipi eliqhekeka i-petroleum liwuhlobo lwensimbi yengxenye yezomnotho. Indima: isetshenziswa kabanzi ekwenzeni izingxenye zesakhiwo nemishini, njengepayipi lokubhola likawoyela, ukushayela imoto. shaft, uhlaka lwebhayisikili kanye nezikafula zensimbi ezisetshenziswa ekwakheni, njll. Ukusebenzisa ithubhu lokuqhekeka kwe-petroleum ukwenza izingxenye zendandatho kungathuthukisa izinga lokusetshenziswa kwempahla, ukwenza inqubo yokukhiqiza ibe lula, konga impahla nesikhathi sokucubungula, njengeringi eligoqayo, umkhono kajack, njll., ibisetshenziswa kabanzi ukwakha ipayipi lensimbi.Ishubhu lokuqhekeka likaphethiloli noma izikhali ezahlukahlukene ezibalulekile, umgqomo, umgqomo nokunye ukuze kwenziwe ipayipi lokuqhekeka likaphethiloli. Ukuma kwendawo ephambanayo.Njengoba indawo yepayipi yokuqhekeka kwe-petroleum inkulu kune-perimeter efanayo, uketshezi oluningi lungathuthwa ngepayipi eliyindilinga.

I-API 5CT ihlukaniswe yaba yi-K55, N80, L80, P110 namanye amamaki ensimbi.

I-Tubing J55 (37Mn5)

I-Casing J55 (37Mn5)

Ipayipi lokuhlanganisa i-J55 (37Mn5)

Ipayipi lensimbi ye-Petroleum (GB/T9948-88) iyipayipi lensimbi elingenamthungo elifanele ishubhu yesithando somlilo, isishintshi sokushisa kanye nepayipi endaweni yokuhluza i-petroleum.

Ipayipi lensimbi lokumba i-geological drilling (YB235-70) isetshenziselwa ukumba okuyisisekelo ngomnyango we-geological, ongahlukaniswa ngepayipi lokubhoboza, ikhola yokubhoboza, ipayipi eliwumgogodla, ipayipi le-casing kanye nepayipi lemvula ngokuya ngokusetshenziswa kwalo.
