Ipayipi lensimbi linengxenye engenalutho, futhi ubude balo bukhulu kakhulu kunobubanzi noma umjikelezo wensimbi.Ngokusho komumo wesigaba, ihlukaniswe ngamapayipi ensimbi ayindilinga, ayizikwele, angama-rectangular futhi amise okukhethekile;Ngokusho kwempahla, ihlukaniswe ngepayipi lensimbi yesakhiwo se-carbon, ipayipi yensimbi ephansi ye-alloy, ipayipi yensimbi ye-alloy kanye nepayipi yensimbi eyinhlanganisela;Ihlukaniswe ngamapayipi ensimbi amapayipi okudlulisa, izakhiwo zobunjiniyela, izinto ezishisayo, imboni ye-petrochemical, ukukhiqizwa kwemishini, ukumba i-geological, imishini yokucindezela okuphezulu, njll;Ngokwenqubo yokukhiqiza, ihlukaniswe yaba ipayipi lensimbi engenamthungo kanye nepayipi lensimbi elishiselwe.Ipayipi lensimbi elingenamthungo lihlukaniswe libe eligoqayo elishisayo nelibandayo (umdwebo), kanti ipayipi lensimbi elishiselwe lihlukaniswe libe ipayipi lensimbi elinomthungo oqondile kanye nepayipi lensimbi elivunguzayo.
I-China ingumkhiqizi oyinhloko wamapayipi ensimbi emhlabeni.Ngo-2020, umphumela kuzwelonke wawungamathani ayizigidi ezingama-89.5427, nokunyuka konyaka ngonyaka ngama-3.73%, okubalelwa ku-60% womkhiqizo womhlaba.Ngesikhathi esifanayo, umjikelezo wokuhlinzekwa kwemboni yamapayipi ensimbi uhlobene eduze nenzuzo yengqalasizinda, ukuphathwa kukamasipala kanye nemboni yokukhiqiza.Ngakho-ke, ngaphansi kokuqaliswa kokusetshenziswa "kohlelo lweminyaka emihlanu" kanye nenqubomgomo entsha yengqalasizinda, ukuhlinzekwa kwemboni yamapayipi ensimbi yaseChina kuzoqhubeka nokugcina inkambiso yokukhula.
