Ipayipi elingenamthungo iyinsimbi ende enengxenye eyisiphambano engenalutho futhi ayikho imithungo ezungezile.Ipayipi lensimbi linendawo ephambanayo engenalutho futhi lisetshenziswa kakhulu njengepayipi lokuthutha uketshezi, njengepayipi lokuthutha uwoyela, igesi yemvelo, igesi, amanzi, nezinto ezithile eziqinile.Uma kuqhathaniswa nensimbi eqinile njengensimbi eyindilinga, ipayipi lensimbi lilula ngesisindo uma linamandla afanayo okugoba namandla okugoqa.Kuyinsimbi eyongayo ye-cross-section.Isetshenziswa kakhulu ekwenzeni izingxenye zesakhiwo kanye nezingxenye zemishini, njengezinduku zokumba i-petroleum, izinsimbi zokuhambisa izimoto, namabhayisikili.Kanye nezikafula zensimbi ezisetshenziswa ekwakheni.Ukusetshenziswa kwamapayipi ensimbi ukwenza izingxenye ze-annular kungathuthukisa ukusetshenziswa kwezinto, kube lula inqubo yokukhiqiza, ukonga izinto kanye namahora okucubungula, njengamaringi okuginqika, imikhono kajack, njll. Njengamanje, amapayipi ensimbi asesetshenziswe kakhulu ekukhiqizeni.Ipayipi lensimbi liphinde libe yinto ebaluleke kakhulu yezikhali ezahlukahlukene ezijwayelekile.Amapayipi, imiphongolo yezibhamu, njll. kumele enziwe ngamapayipi ensimbi.Amashubhu ensimbi angahlukaniswa abe amashubhu ayindilinga kanye namashubhu amise okwesipesheli ngokuya ngobumo bendawo ehlukene yezingxenye eziphambanayo.Njengoba indawo eyisiyingi inkulu kakhulu ngaphansi kwesimo se-perimeter elinganayo, uketshezi oluningi lungathuthwa ngeshubhu eliyindilinga.Ukwengeza, lapho ingxenye yesiphambano sendandatho ingaphansi kokucindezela kwe-radial yangaphakathi noma yangaphandle, amandla afana kakhulu.Ngakho-ke, amapayipi amaningi ensimbi angamapayipi ayindilinga.
Nokho, amapayipi ayindilinga nawo anemikhawulo ethile.Isibonelo, ngaphansi kwesimo sokugoba endizeni, amapayipi ayindilinga awaqinile njengamapayipi ayisikwele noma angama-rectangular.Amanye amathambo emishini yezolimo, ifenisha yokhuni lwensimbi, njll. avame ukusetshenziswa kumapayipi ayisikwele kanye namapayipi angama-rectangular.Ngokusho kokusetshenziswa okuhlukile, amapayipi ensimbi amise okwesipesheli anezinye izinhlobo ze-cross-sectional nawo ayadingeka.
