Isethulo somkhiqizo:
Ukuhlukaniswa kwepayipi lensimbi engagqwali: ipayipi lensimbi engenamthungo kanye nepayipi lensimbi engagqwali elishiselwe (elinemithungo) izigaba ezimbili eziyisisekelo.Ngokusho kobubanzi obungaphandle bepayipi lensimbi lingahlukaniswa libe yipayipi eliyindilinga kanye nepayipi elimise okukhethekile, elisetshenziswa kabanzi yipayipi lensimbi eliyindilinga, kodwa kukhona nezinye isikwele, unxande, i-semicircular, hexagonal, unxantathu olinganayo, octagonal nezinye ezikhethekile. -ipayipi lensimbi elimise.
Ngokusho kokusetshenziswa, ihlukaniswe ngamapayipi ashiselwe jikelele, ipayipi lokushisa lokushisa, ipayipi le-condenser, ipayipi elishiselwe, ipayipi le-oxygen, i-wire casing, ipayipi le-metric welded, ipayipi le-idler, ipayipi lepompo elijulile, ipayipi lemoto, ipayipi le-transformer, ugesi. welding mncane odongeni ipayipi, kagesi Welding ipayipi kanye Kuvunguza ashiselwe ipayipi.
