Izindololwane zokushisela izinqe

(1)Izindololwane zokushisela izinqeingahlukaniswa ibe yizindololwane zokushisela izinqe ezinde kanye nezindololwane zokushisela izinqe ezimfushane ngokwerediyasi yokugoba kwazo. Irediyasi yokugoba yendololwane yokushisela izinqe ezinde ilingana nobubanzi obuphindwe ka-1.5 bepayipi, okungukuthi, R=1.5D. Irediyasi yokugoba yendololwane yokushisela izinqe ezimfushane ilingana nobubanzi obungaphandle bepayipi, okungukuthi, R=1D. Kule fomula, u-D ububanzi bendololwane yokushisela izinqe, kanti u-R ubude bendololwane yokugoba. Uma kungekho ncazelo ekhethekile, indololwane engu-1.5D isetshenziswa ngokuvamile.
(2) Ngokwezinga lokucindezela, kunezinhlobo ezingaba yishumi nesikhombisa, ezifana nezindinganiso zamapayipi aseMelika, okuhlanganisa: ama-Sch5, ama-Sch10, ama-Sch10, ama-Sch20, ama-Sch30, ama-Sch40, ama-STD, ama-Sch40, ama-Sch60, ama-Sch80, ama-XS; ama-Sch80, ama-Sch100, ama-Sch120, ama-Sch140, ama-Sch160, ama-XXS, okuvame ukusetshenziswa kuwo ama-STD nama-XS.
(3) Ngokwe-engeli yendololwane, kunezindololwane zokushisela izinqe ezingama-degree angu-45, izindololwane zokushisela izinqe ezingama-degree angu-90, izindololwane zokushisela izinqe ezingama-degree angu-180 kanye nezinye izindololwane ezinezingqimba ezahlukene.
(4) Izinto zokwakha yilezi: insimbi yekhabhoni, insimbi ye-alloy kanye nensimbi engagqwali.
