Amapayipi ensimbi angenamthungo ahlukaniswe izinhlobo ezimbili: amapayipi ensimbi angenamthungo ashiswayo (akhishwayo) kanye namapayipi ensimbi angenamthungo adonswayo (agoqwe) abandayo ngenxa yezinqubo zawo zokukhiqiza ezahlukene.
Ukubuka konke kwenqubo: ukugoqa okushisayo (ipayipi lensimbi elingenamthungo elikhishwe): i-billet yeshubhu eliyindilinga → ukushisa → ukubhoboza → ukugoqa okunemiphetho emithathu, ukugoqa okuqhubekayo noma ukukhishwa kweshubhu → ukususwa kweshubhu → usayizi (noma ukunciphisa) → ukupholisa → ishubhu yeshubhu.
Ngenxa yokusetshenziswa kwawo okuhlukene, amapayipi ensimbi angenamthungo ahlukaniswe ngezinhlobo ezilandelayo: GB/T8162 (amapayipi ensimbi angenamthungo ngezinjongo zokwakha), insimbi ye-carbon No. 20 kanye nensimbi engu-45; insimbi ye-alloy Q345, 20Cr, 40Cr, 20CrMo, 30-35CrMo, 42CrMo, njll.

I-API SPEC5CT (Casing and Tubing Specification) ihlanganiswe futhi yanyatheliswa yi-American Petroleum Institute (American Petreleum Institute, ebizwa ngokuthi "API") futhi isetshenziswa kakhulu emhlabeni jikelele.
Phakathi kwazo, ikheshi: ipayipi elisuka ebusweni bomhlaba liye emthonjeni njengophahla lodonga lomthombo, kanti amapayipi axhunywe ngamakhola. Izinto eziyinhloko yizinga lensimbi ezifana ne-J55, i-N80, ne-P110, kanye nezinga lensimbi ezifana ne-C90 ne-T95 ezimelana nokugqwala kwe-hydrogen sulfide.
Ipayipi likawoyela: Ipayipi elifakwa ekhasejini lisuka phansi liye engqimbeni likawoyela, bese amapayipi exhunywe ngama-coupling noma ngokuhlangene. Izinto eziyinhloko yi-J55, N80, P110, kanye namazinga ensimbi afana ne-C90 kanye ne-T95 amelana nokugqwala kwe-hydrogen sulfide. I-API SPEC 5L (Imininingwane Yepayipi Lomugqa), ehlanganiswe futhi yanyatheliswa yi-American Petroleum Institute, ivame ukusetshenziswa emhlabeni wonke. Ipayipi lomugqa: liwukuthutha uwoyela, igesi noma amanzi ukusuka emgodleni ukuya embonini kawoyela negesi ngepayipi lomugqa.
Amapayipi omugqa afaka amapayipi angenamthungo nahlanganisiwe, kanti amaphethelo amapayipi aneziphetho ezisicaba, iziphetho ezinezintambo kanye neziphetho zesokhethi; izindlela zokuxhuma ukushisela kokuphela, ukuxhumeka kwekhola, ukuxhumeka kwesokhethi, njll. Izinto eziyinhloko zepayipi yi-B, X42, X56, X65, X70 kanye nezinye izinhlobo zensimbi.
Izimbobo ezisetshenziselwa amapayipi ensimbi ahlanganisiwe yizingqwembe zensimbi noma insimbi eqoshiwe. Ngenxa yezinto ezisetshenziswayo nezinqubo zazo ezahlukene, amapayipi ahlanganisiwe ahlukaniswe ngamapayipi ahlanganisiwe esithandweni, amapayipi okushisela kagesi (ukushisela ukumelana) kanye namapayipi ahlanganisiwe e-arc azenzakalelayo. Ngenxa yesimo sawo sokugcina, ahlukaniswe ngamapayipi ahlanganisiwe ayindilinga kanye namapayipi ahlanganisiwe anomumo okhethekile (isikwele, isicaba, njll.) ngezinjongo ezahlukene, futhi ahlukaniswe ngezinhlobo ezilandelayo:
