(1)Ko te raima e whai kiko anaKa taea te wehewehe ki nga tohu riki roa me te riipene poto poto me te raima i runga i o raatau radius o te koki. Ko te radius o te kokonga o te raima radius roa e rite ana ki te 1.5 nga wa o te diameter o waho o te putorino, ara, r = 1.5d. Ko te radius o te kaki o te radius Rorohiko Whakatakotoria he rite ki te diameter o waho o te putorino, ara, r = 1d. I roto i te tātai, ko D te diameter o te kaimareke o te reeti, ko R ko te radius o te piko. Mena kaore he whakaahuatanga motuhake, ko te 1.5d te raima e whakamahia ana.
(2) According to the pressure level, there are about seventeen kinds, which are the same as the American pipe standards, including: Sch5s, Sch10s, Sch10, Sch20, Sch30, Sch40s, STD, Sch40, Sch60, Sch80s, XS; Sch80, Sch100, Sch120, SCH140, SCH160, SCH160, XXS, ko te mea e whakamahia ana ko te STD me te XS.
(3) E ai ki te koki o te hiku, e 45-tohu-a-tohu-a-ringa-rua-tohu-elbull, te tohu-a-ringa-a-ringa me etahi atu waahanga rereke.
(4) Nga taonga: Ko te kowiri kaiano, he kowiri tira me te kowiri tira.
