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 anengcindezi ephansi naphakathi, amapayipi ensimbi abilayo, amapayipi ensimbi axubile, amapayipi aqhekeka e-petroleum, namanye amapayipi ensimbi, amapayipi ensimbi agoqelwe (dayela) angenamthungo ahlanganisa nensimbi enezindonga ezincane zekhabhoni. amapayipi, i-alloy amapayipi ensimbi anezindonga ezincane, 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 ukushuba kodonga kungafinyelela 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 esezingeni eliphezulu efana no-10, 20, 30, 35, 45, 16Mn, 5MnV nezinye izinsimbi zesakhiwo ezinengxubevange ephansi noma 40Cr, 30CrMnSi, 45Mn2, 40MnB nezinye izinsimbi zengxubevange. ziyashiswa noma ziyagoqwa.
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.
