Kunezinhlobo ezimbili zamapayipi ensimbi angenamthungo: amapayipi ensimbi angenamthungo ashiswayo kanye namapayipi ensimbi angenamthungo abandayo.
Amapayipi ensimbi angenamthungo ashiswayo ahlukaniswe ngamapayipi ensimbi ajwayelekile, amapayipi ensimbi ebhoyila anomfutho ophansi nophakathi, amapayipi ensimbi ebhoyila anomfutho ophakeme, amapayipi ensimbi e-alloy, amapayipi okuqhekeka kwephethiloli, amapayipi ensimbi ye-geological kanye namanye amapayipi ensimbi.
Ngaphezu kwamapayipi ensimbi ajwayelekile, amapayipi ensimbi ebhoyila anomfutho ophansi nophakathi, amapayipi ensimbi ebhoyila anomfutho ophezulu, amapayipi ensimbi e-alloy, amapayipi okuqhekeka kwephethiloli, kanye namanye amapayipi ensimbi, amapayipi ensimbi angenamthungo aqoqwe ngokubandayo (adial) ahlanganisa namapayipi ensimbi angenamthungo anezindonga ezincane zekhabhoni, amapayipi ensimbi angenamthungo anezindonga ezincane ze-alloy, amapayipi ensimbi anephrofayili, njll.
Ububanzi bangaphandle bepayipi elingenamthungo eligoqwe ngokushisa ngokuvamile bukhulu kuno-32mm, kanti ubukhulu bodonga bungu-2.5-75mm. Ububanzi bepayipi lensimbi elingenamthungo eligoqwe ngokushisa bungafinyelela ku-6mm, kanti ubukhulu bodonga bungafinyelela ku-0.25mm. Ububanzi bangaphandle bepayipi elinezindonga ezincane bungafinyelela ku-5mm, kanti ubukhulu bodonga bungaphansi kuka-0.25mm. Ukugoqwa okubandayo kunokunemba okuphezulu kunokweqiwa okushisayo.
Amapayipi ensimbi angenamthungo okusetshenziswa okuvamile: enziwe ngensimbi yekhabhoni esezingeni eliphezulu njenge-10, 20, 30, 35, 45, 16Mn, 5MnV kanye nezinye izinsimbi zesakhiwo ezi-alloy eziphansi noma i-40Cr, 30CrMnSi, 45Mn2, 40MnB kanye nezinye izinsimbi ze-alloy ezigoqwa ngokushisa noma ezigoqwa ngokushisa.
Amapayipi angenamthungo angu-10, 20 kanye namanye angenamthungo ensimbi ephansi yekhabhoni asetshenziswa kakhulu kumapayipi okuhambisa uketshezi. Amapayipi angenamthungo enziwe ngensimbi ephansi yekhabhoni efana no-45 no-40Cr asetshenziselwa ukukhiqiza izingxenye zemishini, njengezingxenye ezicindezelwe zezimoto nama-tractor. Ngokuvamile, amapayipi ensimbi angenamthungo asetshenziselwa ukuqinisekisa amandla nokuhlolwa kokuthamba. Amapayipi ensimbi ashisayo athunyelwa esimweni sokugoqwa okushisayo noma sokuphathwa kokushisa; amapayipi ensimbi abandayo athunyelwa esimweni sokuphathwa kokushisa.
