(1)Izindololwane zokushisela izinqezingahlukaniswa zibe izindololwane zokushisela ezinqenqemeni ezinde kanye nezindololwane zokushisela ze-radius butt ezimfishane ngokuya ngobubanzi bazo bokugoba.Iradiyasi yokugoba yendololwane yokushisela engaba isinqe ende ilingana nezikhathi ezingu-1.5 zobubanzi obungaphandle bepayipi, okungukuthi, R=1.5D.Irediyasi yokugoba yendololwane yokushisela ye-radius butt emfushane ilingana nobubanzi obungaphandle bepayipi, okungukuthi, R=1D.Efomini, u-D uwububanzi bendololwane ye-butt welding, futhi u-R uyiradiyasi yokugoba.Uma ingekho incazelo ekhethekile, indololwane engu-1.5D ngokuvamile isetshenziswa.
(2) Ngokwezinga lokucindezela, cishe kunezinhlobo eziyishumi nesikhombisa, ezifanayo nezindinganiso zamapayipi aseMelika, okuhlanganisa: Sch5s, Sch10s, Sch10, Sch20, Sch30, Sch40s, STD, Sch40, Sch60, Sch80s, XS;I-Sch80 , i-Sch100, i-Sch120, i-Sch140, i-Sch160, i-XXS, okuvame ukusetshenziswa kuyo i-STD ne-XS.
(3) Ngokwe-engeli yendololwane, kunezindololwane ze-butt-welding ezingama-45-degree, izindololwane ezishisela izinqe eziyi-90-degree, izindololwane ezishisela izinqe eziyi-180-degree nezinye izindololwane ezinama-engeli ahlukene.
(4) Izinto ezisetshenziswayo yilezi: i-carbon steel, i-alloy steel nensimbi engagqwali.
