Indololwane eshiselwe yenziwe ngokugoba ipayipi futhi ingashiselwa, ngakho ibizwa ngokuthi indololwane eshiselwe, akusho ukuthi inezinsimbi. Eqinisweni, ngokuphambene nalokho, indololwane eshiselwe yenziwe ngepayipi eliqondile lokunyathela nokugoba. Uma kucatshangelwa ukucindezeleka kwesakhiwo, ipayipi elingenamthungo livame ukusetshenziswa. Esikhundleni sepayipi elishiselwe., Okubizwa ngokuthi indololwane engenamthungo iyi-casting futhi ayikwazi ukushiselwa.
Indololwane eshiselwe ayifani nendololwane engenamthungo, kodwa futhi inokugqagqana. Ukukhiqizwa kwendololwane kuhlukaniswe nge-welding, stamping, pushing and casting. I-Seamless isho indololwane ngaphandle komthungo wokushisela, hhayi indololwane eshiselwe. Indololwane enesitembu inomthungo oqondile wokunyathela indololwane kanye nendololwane yokunyathela engenamthungo, enqunywa ubunjalo bombungu wepayipi.
Indololwane iwumkhiqizo ongenamthungo futhi ingacutshungulwa ngokuqondile epayipini elingenamthungo; Ama-elbows angamalunga, adalwe ngokushisela.
Umehluko phakathi kwendololwane eshiselwe kanye nendololwane engenamthungo ukuthi indololwane eshiselwe izinqe inamashisela amabili, indololwane eshiselwe istraight ineweld eyodwa, kanti indololwane engenamthungo ayinayo i-weld.
1. Umehluko wokubukekaUmehluko phakathi kwe-Seamlessindololwanefuthi indololwane ezishiselwe ukuthi kukhona weld. Ngaphezu kwalokho, ubukhulu bendololwane engenamthungo abulingani uma buqhathaniswa nendololwane eshiselwe.
2. Umehluko enqubweni yokubumbaInqubo yokusebenzisa indololwane engenamthungo iyafana naleyo yokushisela indololwane. Kodwa-ke, umehluko phakathi kwakho kokubili ukuthi ukukhiqizwa kwendololwane kuhlukaniswe nge-welding, stamping, pushing and casting. Indololwane engenamthungo yenziwe ngepayipi lensimbi elingenamthungo, ngaphandle kwe-welding seam noma indololwane eshiselwe. I-elbow eshiselwe yenziwe nge-steel plate eyenziwe ngokugoba kanye nezinqubo ezahlukene zokushisela.
3. Ukusetshenziswa okuhlukileIzindololwane ezingenamthungo zisetshenziswa kakhulu njengamapayipi noma izingxenye zesakhiwo zokudlulisa uketshezi embonini yemishini, kuyilapho izindololwane ezishiselwe ngokuhlanganyela zisetshenziswa kakhulu embonini yezokwakha, njengoketshezi olunomfutho ophansi, njengamanzi nomoya ocindezelwe. Kodwa-ke, ama-penstocks abandakanyekayo awanamthungo.
4. Umehluko kasayizi otholakalayoKubakhiqizi abaningi bezindololwane zamapayipi angenamthungo e-China, ubukhulu bezindololwane zamapayipi angenamthungo buyi-intshi engu-24 futhi ububanzi obungaphandle bungu-609.6 mm. Ngokuphambene, akukho umkhawulo wokugoba ashiselwe, okungase isukela 1-1/2 intshi 48.3mm ukuze 100 intshi 2540mm.
5. Amanani ahlukeneNjengoba inqubo yokukhiqiza engenamthungo iyinkimbinkimbi kakhulu, intengo ibiza kakhulu kune-elbow ehlangene, futhi ukujoyina kwenziwa ikakhulukazi nge-steel plate (i-steel strip) nge-welding yesibili, eshibhile futhi isetshenziswa kabanzi.
