Ngokwendlela yokukhiqiza, ipayipi elingenamthungo lihlukaniswe libe ipayipi eligoqiwe elishisayo, ipayipi eligoqiwe elibandayo, ipayipi elidonsa abandayo, ipayipi elikhishwe, ipayipi eliphezulu, nokunye okunjalo. Ngokusho kokuma kwesigaba, ipayipi yensimbi engenamthungo ihlukaniswe yaba izinhlobo ezimbili: isimo esiyindilinga nesimo esingavamile, futhi ipayipi elibunjiwe linomumo wesikwele, i-elliptical shape nokunye okunjalo. Ubukhulu obukhulu bungama-650mm kanti ubukhulu obuncane bungu-0.3mm. Ipayipi lensimbi elingenamthungo lisetshenziswa kakhulu njengepayipi lokumba le-petroleum geological, ipayipi eliqhekeka embonini ye-petrochemical, ipayipi likabhayela, ipayipi elithwele kanye nepayipi lensimbi elinembayo eliphezulu lemoto, ugandaganda kanye nendiza.
