Namuhla sethula ipayipi lensimbi elingenamthungo elisetshenziswa kakhulu, ipayipi likawoyela (GB9948-88) lifanelekela ipayipi lesithando sokuhlanza uwoyela, i-heat exchanger kanye nepayipi elingenamthungo.

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.

Ipayipi likawoyela liwuhlobo lwensimbi ende enengxenye engenalutho futhi engenalo ijoyinti elizungezile, kuyilapho ipayipi lokuqhekeka kukaphethiloli liwuhlobo lwensimbi yengxenye engabizi.
I-API: Kuyisifinyezo se-English American Petroleum Institute, okusho isiShayina i-American Petroleum Institute.

I-OCTG: Yisifinyezo se-Oil Country Tubular Goods, okusho ipayipi elikhethekile likawoyela ngesiShayina, okuhlanganisa i-Oil casing eqediwe, ipayipi lokubhoboza, ikhola lokubhoboza, ikhola, kanye nejoyinti elifushane, njll.

Ukufaka ipayipi: Ipayipi elisetshenziswa ekukhiqizeni uwoyela negesi, ekufakweni kwamanzi, nasekuqhekekeni kwe-asidi emthonjeni.

Ibhokisi: Ipayipi lisuka ebusweni bomhlaba liye emgodini obholwe kahle njengothango lokuvimbela udonga ukuthi lungawi.

Ipayipi lokubhoboza: ipayipi elisetshenziselwa ukubhoboza imigodi.

Ipayipi: ipayipi elisetshenziselwa ukuthutha uwoyela negesi.
