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 ishubhu lokuqhekeka kwe-petroleum ukwenza izingxenye zendandatho kungathuthukisa izinga lokusebenzisa izinto, kube lula inqubo yokukhiqiza, ukonga impahla kanye. isikhathi sokucubungula, njengendandatho egoqayo, umkhono kajack, njll., siye sasetshenziswa kabanzi ukwenza ipayipi lensimbi. Ishubhu lokuqhekeka likaphethiloli noma izikhali ezihlukahlukene ezisetshenziswayo ezibalulekile, umgqomo, umgqomo nokunye ku-petroleum cracking tube to manufacture.Petroleum ipayipi eliqhekekayo lingahlukaniswa libe ipayipi eliyindilinga kanye nepayipi elimise okukhethekile ngokusho komumo wendawo enqamula ingxenye.Njengoba indawo yepayipi yokuqhekeka kwe-petroleum inkulu kakhulu efanayo 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
