Kunezinhlobo ezimbili zamapayipi ensimbi angenamthungo: amapayipi ensimbi angenamthungo nagoqelwe ngokubandayo (dayela).
Amapayipi ensimbi angenamthungo agoqelwe ngokushisa ahlukaniswe amapayipi ensimbi ajwayelekile, amapayipi ensimbi anomfutho ophansi naphakathi, amapayipi ensimbi anomfutho ophakeme, amapayipi ensimbi eyingxubevange, amapayipi aqhekeka kaphethiloli, amapayipi ensimbi e-geological kanye namanye amapayipi ensimbi.
Ngaphezu kwamapayipi ensimbi avamile, amapayipi ensimbi anomfutho ophansi naphakathi, amapayipi ensimbi kabhayela ocindezelwe kakhulu, amapayipi ensimbi axubile, amapayipi aqhekeka uphethiloli, namanye amapayipi ensimbi, amapayipi ensimbi angenamthungo (okudayela) abandayo ahlanganisa namapayipi ensimbi anezindonga ezincane zekhabhoni, amapayipi ensimbi anezindonga ezincane ezihlanganisiwe, amapayipi ensimbi anephrofayili, njll.
Ububanzi bangaphandle bepayipi elingenamthungo eligoqwe elishisayo ngokuvamile bukhulu kuno-32mm, futhi ukujiya kodonga kungu-2.5-75mm. Ububanzi bepayipi lensimbi elingenamthungo elibandayo lingafinyelela ku-6mm, futhi ubukhulu bodonga bungafinyelela ku-0.25mm. Ububanzi bangaphandle bepayipi elinezindonga ezincane bungafinyelela ku-5mm, futhi ukushuba kodonga kungaphansi kuka-0.25mm. Ukugoqa okubandayo kunokunemba okuphezulu kunokulinganisa okushisayo.
Amapayipi ensimbi angenamthungo asetshenziswa ngokujwayelekile: enziwe ngensimbi yekhabhoni yekhwalithi ephezulu efana no-10, 20, 30, 35, 45, 16Mn, 5MnV nezinye izinsimbi zesakhiwo ezinengxubevange ephansi noma 40Cr, 30CrMnSi, 45Mn2, 40MnB ama-alloy steels abandayo noma amanye ama-allolled steels.
10, 20 kanye namanye amapayipi angenamthungo ensimbi enekhabhoni ephansi asetshenziselwa ikakhulukazi amapayipi adlulisa uketshezi. Amashubhu angenamthungo enziwe ngensimbi ye-carbon steel ephakathi njenge-45 kanye ne-40Cr asetshenziselwa ukwakha izingxenye zemishini, njengezingxenye ezigcizelelwe zezimoto nogandaganda. Ngokuvamile, amapayipi ensimbi angenamthungo asetshenziselwa ukuqinisekisa ukuqina nokuhlolwa kokucaba. Amapayipi ensimbi ashisayo ahanjiswa esimweni esishisayo noma esiphethwe ukushisa; amapayipi ensimbi abandayo ahanjiswa esimweni sokushisa.
