ʻO ke kumu o ka paipu he ʻāpana paipu i kūlou i kekahi kihi e hoʻohui i nā paipu ʻelua. hiki iā lākou ke ʻaneʻane i nā aniani kūlou a me nā kihi. Hana pinepine ʻia nā piʻo Pipe ma ka pūnaewele e hālāwai i kahi pono kikoʻī e ke kūnou wela ʻana a i ʻole ke anu anuanu. ʻO ke kuʻekuʻe aku he kūloko paipu kikoʻī e like me ke ANSI / ASME B16.9 maʻamau (a i ʻole EN 10253, a i ʻole nā kūlana pili pono paipu). ʻO ka maʻa mau o nā kuʻekuʻe i ke aniani kūlou o 1.5D a i ʻole 1D (Eia ke ʻano o ke D o ke anawaena o kēia pio), i kapa ʻia ʻo "Long Radius elbow (LR elbow)" a i ʻole "Short s Radius elbow (SR elbow)". a ʻo ke kihi o kahi kuʻe lima he 45 kekelē a i ʻole 90 kekelē maʻamau, i kekahi mau manawa aia kekahi mau kuʻekuʻe i hoʻolālā ʻia e 30 kekelē, 60 kekelē, 180 kekelē a i ʻole nā ʻaoʻao ʻē aʻe.

Pono nā piʻo o ka paipu e like me ke kūlana o ANSI / ASME B16.49 i hōʻike ʻole i ka radius anuenue a me ka huina, ʻo ka radius bend paipu maʻamau he 2.5D, 3D, 5D, 7D a i ʻole 8D, akā hiki ke lilo i kekena ʻē aʻe radius e like me ka hoʻolālā e pono ai, a hiki i ke kūlou ʻana i kēlā me kēia kekelē, 5, 10, 15, 90 kekelē a i ʻole nā mea ʻē aʻe. ʻ saidlelo nā poʻe "He kuʻekuʻe nā piʻo āpau akā ʻaʻole kūlou nā kuʻekuʻe lima", ʻaʻole ia he ʻoiaʻiʻo. ʻOiaʻiʻo "ʻO nā kuʻekuʻe āpau he kūlou paipu akā ʻaʻole nā piʻo āpau he kuʻekuʻe" ʻoi aku ke kūpono.
