ithubhu yensimbi engenamthungo

Ipayipi lensimbi elingenamthungo liwuhlobo lwensimbi ende enengxenye engenalutho futhi awekho amalunga azungezile. Ipayipi lensimbi elingenamthungo linengxenye engenalutho futhi lingasetshenziswa njengepayipi lokudlulisa uketshezi, njengowoyela, igesi yemvelo, igesi, amanzi nezinye izinto eziqinile. Uma kuqhathaniswa nensimbi eqinile njengensimbi eyindilinga, ipayipi lensimbi engenamthungo lilula ngesisindo lapho ukugoba kwalo namandla okugoqa kufana. Iwuhlobo lwensimbi yesigaba sezomnotho, esetshenziswa kabanzi ukwenza izingxenye zesakhiwo kanye nezingxenye zemishini, njengepayipi lokubhoboza uwoyela, umshini wokuhambisa imoto, uhlaka lwamabhayisikili kanye nesikafula sensimbi esisetshenziswa ekwakheni. Ukukhiqiza izingxenye ezimise okwendandatho ngamapayipi ensimbi angenamthungo kungathuthukisa izinga lokusetshenziswa kwezinto, kwenze kube lula inqubo yokukhiqiza, futhi konge izinto zokwakha namahora okucubungula, njengamaringi aphetheyo, imikhono kaJack, njll., ekhiqizwa kabanzi ngamapayipi ensimbi. Ipayipi lensimbi liphinde libe yinto ebaluleke kakhulu yezikhali ezahlukahlukene ezijwayelekile. Umgqomo nomgqomo wesibhamu kufanele wenziwe ngepayipi lensimbi. Ipayipi lensimbi lingahlukaniswa libe yipayipi eliyindilinga kanye nepayipi elimise okukhethekile ngokusho kokuma kwendawo ye-cross-sectional. Ngenxa yokuthi indawo eyisiyingi inkulu kakhulu ngaphansi kwesimo se-perimeter elinganayo, uketshezi oluningi lungathuthwa ngeshubhu eliyindilinga. Ukwengeza, lapho isigaba sendandatho singaphansi kokucindezela kwe-radial yangaphakathi noma yangaphandle, amandla afana kakhulu. Ngakho-ke, iningi lamashubhu ensimbi angamashubhu ayindilinga. Kodwa-ke, amapayipi ayindilinga nawo anemikhawulo ethile. Isibonelo, ngaphansi kwesimo sokugoba kwendiza, amandla okugoba amapayipi ayindilinga awaqinile njengalawo amapayipi ayisikwele kanye namapayipi angama-rectangular. Amapayipi ayisikwele nawonxande avame ukusetshenziswa ohlakeni lwemishini ethile yezolimo namathuluzi, ifenisha yensimbi neyokhuni, njll. Amapayipi ensimbi anomumo okhethekile anamanye amamo e-cross-section nawo ayadingeka ngezinhloso ezahlukene.

Ipayipi lensimbi elishiselwe

Ipayipi lensimbi elishiselwe, elaziwa nangokuthi ipayipi elishiselwe, ipayipi lensimbi elenziwe ngepuleti lensimbi noma umucu wensimbi ngemuva kokugoqa nokwenza. Ipayipi lensimbi elishiselwe linezinzuzo zenqubo yokukhiqiza elula, ukusebenza kahle kokukhiqiza okuphezulu, izinhlobo eziningi nezincazelo kanye nokutshalwa kwezimali kwemishini encane, kodwa amandla ayo ajwayelekile aphansi kunalawo epayipi lensimbi engenamthungo. Kusukela ngeminyaka yawo-1930s, ngokuthuthuka okusheshayo kokukhiqizwa okuqhubekayo kwe-strip esezingeni eliphezulu kanye nenqubekelaphambili yobuchwepheshe bokushisela nokuhlola, ikhwalithi yokushisela ibilokhu ithuthukiswa ngokuqhubekayo, izinhlobonhlobo kanye nokucaciswa kwamapayipi ensimbi ashiselwe kuye kwanda, namapayipi ensimbi angenamthungo ane. ishintshwe emikhakheni eminingi. Amapayipi ensimbi ashiselwe ahlukaniswe abe ipayipi elihlanganisiwe le-seam eliqondile kanye nepayipi elihlanganisiwe elivunguzayo ngokusho kohlobo lwe-weld.
