Ka taea e koe te tatau i te roa tapahi tika o te tangohanga rakau taura rapa me te tatau e whai ake nei.Tena koa whakauhia nga uara tika o te diameter o roto (ID) me te waahanga-whakawhiti (CS) i te tuatahi katahi ka mahi i etahi tatauranga ngawari.
Hei tauira:
Ma te whakamahi i te taura 10mm (CS) diameter, e hiahia ana te kaiwhakamahi ki te hanga i tetahi mowhiti-o paerewa he 300-mm te whanui o roto.
Ko te tatauranga mo te tapahi i te roa o te taura hei hanga i te mowhiti-o e whai ake nei:
300 (ID)+10 (CS)= 310
310×3.1415926= 973.89mm
Me tapahi te taura ki te 973.89 mm te roa hei hanga i te mowhiti o-mowhiti.
Ko te rahi o te taura paerewa ka inehia ma te diameter o te tohu.E whakaatu ana tenei tūtohi i te rahi emepaea me te rahi ine.Ka whakaatu hoki te ripanga i te herenga o-mowhiti, kia taea ai e koe te tatau tika mena ka tika te taura mo to tono tika.I roto i enei rahi, he rereke te rahi o te inihi mai i te rahi o-ringi AS568, ko te rahi o te metric kei runga i te maakete Haina me etahi maakete o tawahi.Ko te tikanga, ka taea e tatou te hanga i enei rahi katoa o te taura i te kounga teitei, te utu whakataetae, me te tuku tere.Mena kaore i te raarangi te rahi ki te teepu, me waea mai ki a maatau ki te korero mo to taura kua whakaritea.He tino ngawari noa iho te takai o te taura rapa, ka herea ranei ki te roera.Tena koa tono kia rite ki o hiahia.
