Ipayipi lensimbi likaphethiloli liwuhlobo lwensimbi ende enengxenye engenalutho futhi alihlanganisi nxazonke, kuyilapho ipayipi lokuqhekeka likaphethiloli liwuhlobo lwensimbi yesigaba somnotho. Indima: isetshenziswa kabanzi ekwenzeni izingxenye zesakhiwo nemishini, njengepayipi lokubhoboza uwoyela, umshini wokushayela imoto, uhlaka lwebhayisikili kanye nezikafula zensimbi ezisetshenziswa ekwakheni, njll. Ukusebenzisa izingxenye zokuqhekeka kwe-petroleum kungathuthukisa inqubo yokuqhekeka kwe-petroleum, ukukhiqiza izingxenye zokuqhekeka kwe-petroleum kungenza kube lula ukukhiqiza izingxenye zokuqhekeka kwe-petroleum ukwenza lula ukuqhekeka kwe-petroleum. isikhathi sokucubungula, njengendandatho egoqayo, umkhono kajack, njll., siye sasetshenziswa kabanzi ukwenza ipayipi lensimbi. Ipayipi lokuqhekeka likaphethiloli noma izikhali ezihlukahlukene ezidingekayo, umgqomo, umgqomo nokunye kuya ku-petroleum cracking tube ukuze kukhiqizwe. Ipayipi lokuqhekeka likaphethiloli lingahlukaniswa libe ipayipi eliyindilinga kanye nepayipi elimise okukhethekile ngokuya ngokuma kwendawo yepayipi le-cross-seum efanayo nendawo yokuqhekeka kwepayipi indawo enkulu kunazo zonke. umjikelezo, uketshezi oluthe xaxa 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.

Izinga lokusebenzisa ipayipi lensimbi elingenamthungo
