Okokuqala, ukuhlukaniswa kwamapayipi
1. Ihlukaniswa ngendlela yokukhiqiza
(1) Ipayipi elingenamthungo – ipayipi eligoqiwe elishisayo, ipayipi eligoqiwe elibandayo, ipayipi elidonsayo, ipayipi elikhishwe ngaphandle, ukugqekezwa kwamapayipi
(2) ipayipi elishiselwe
(a) Ngokwenqubo - ipayipi elishiselwe i-arc, ipayipi elishiselwe ukumelana nogesi (imvamisa ephezulu, imvamisa ephansi), ipayipi elishiselwe igesi, ipayipi elishiselwe esithandweni somlilo
(b) Ngokomthungo we-weld – ipayipi elishiselwe ngomthungo oqondile, ipayipi elishiselwe elithandelayo
2, ngokuya ngesimo sesigaba
(1) Ipayipi lensimbi lesigaba esilula – ipayipi lensimbi eliyindilinga, ipayipi lensimbi eliyisikwele, ipayipi lensimbi elingunxantathu, ipayipi lensimbi elingunxantathu, ipayipi lensimbi elinezinhlangothi ezine, ipayipi lensimbi yedayimane, ipayipi lensimbi eliyi-octagonal, indilinga yensimbi eyisiyingi, enye
(2) Ipayipi lensimbi lengxenye eyinkimbinkimbi—ipayipi lensimbi elingalingani elingu-hexagonal, ipayipi lensimbi elinamacembe amahlanu amise okweplamu, ipayipi lensimbi eliyi-convex eliphindwe kabili, ipayipi lensimbi eliyi-concave eliphindwe kabili, ipayipi lensimbi elimise okwekhabe, ipayipi lensimbi elikhonkolo, ipayipi likathayela, ipayipi lensimbi, abanye
3, ngokuya ngezigaba zokuqina kodonga - ipayipi lensimbi elinezindonga ezincane, ipayipi lensimbi enodonga oluwugqinsi
4. Ukuhlelwa ngokusetshenziswa - ipayipi lensimbi lamapayipi, ipayipi lensimbi lezinto ezishisayo, ipayipi lensimbi lemboni yemishini, i-petroleum, ipayipi lensimbi lokumba le-geological, ipayipi lensimbi yesiqukathi, ipayipi lensimbi yemboni yamakhemikhali, ipayipi lensimbi lenjongo ekhethekile, nokunye.
