(1)Kuʻekuʻe kuʻekuʻe wāwaehiki ke hoʻokaʻawale ʻia i nā kuʻekuʻe kuʻekuʻe wāwae lōʻihi a me nā kuʻekuʻe kuʻekuʻe pōkole pōkole e like me kā lākou radius o curvature.Ua like ka radius o ka curvature o ka radius butt welding elbow me 1.5 manawa o ke anawaena o waho o ka paipu, oia hoi, R=1.5D.Ua like ka radius o ka curvature o ka radius butt welding elbow me ke anawaena o waho o ka paipu, oia hoi, R=1D.I ke kumu, ʻo D ke anawaena o ka kuʻekuʻe kuʻekuʻe wāwae, a ʻo R ka radius o ka curvature.Inā ʻaʻohe wehewehe kikoʻī, hoʻohana maʻamau ka kuʻekuʻe 1.5D.
(2) E like me ka pae kaomi, aia ma kahi o ʻumikumamāhiku mau ʻano, e like me nā kūlana paipu ʻAmelika, e like me: Sch5s, Sch10s, Sch10, Sch20, Sch30, Sch40s, STD, Sch40, Sch60, Sch80s, XS;Sch80 , Sch100, Sch120, Sch140, Sch160, XXS, ʻo ia ka mea maʻamau i hoʻohana ʻia ʻo STD a me XS.
(3) E like me ka huina o ka kuʻekuʻe lima, aia nā kuʻekuʻe kuʻekuʻe 45-degere, 90-degere kuʻekuʻe kuʻekuʻe lima, 180-degere kuʻekuʻe kuʻekuʻe lima a me nā kuʻekuʻe lima ʻē aʻe me nā kihi ʻokoʻa.
