Ko te putorino kowiri tira, e mohiotia ana ko te ngongo korekore he kowiri tira, he rango puare roa e whakamahia ana mo te neke wai (wai, hau ranei).
Ko te "pupa parakore korekore" me te "ngongo kowiri tira" ka tata te whakawhiti, ahakoa he rereke nga rereketanga-te nuinga, he uaua ake nga whakaritenga miihini o te ngongo i te paipa.
He kaihanga ngaio a Cepheus e mahi ana i nga paipa tuitui i roto i te rahi, te reo, me te iti te diameter.
He maha nga putorino kowiri tira e mahia ana me nga whakaritenga katoa me te kounga teitei.
He taputapu pai a Cepheus me te whakahaere kounga katoa, ka whakatuu i te punaha whakahaere kounga hou, te whakauru i nga hangarau o te ao me te whakamahi i nga tikanga whakangao o te ao.
Ko te putorino kowiri tira e whakamahia nuitia ana i roto i nga umanga penei i te hinu, te ahumahi matū, te miihini, te hiko hiko, te muka matū, te hanga pepa, te ta me te tae, nga kai me nga waahanga pneumatic etc.
Ka whakawhiwhia te kamupene ki nga taputapu tirotiro katoa me te tango i nga paerewa hangarau mo nga hua penei: te paipa kore mo te kawe wai, te paipa kore mo te hanga, te maamaa mo te kohua me te whakawhiti wera.
Ko te diameter o waho o te kowiri tira ka mahia e matou mai i te 4.0mm ki te 1219mm. Ko te matotoru o te pakitara he 0.5mm ki te 100mm. Mo te whakarewa, he tino nui ta matou.

Tuhipoka:
Ko te OD te diameter o waho kua tohua.
Ko te WT te matotoru pakitara kua tohua
Ko nga paipa kowiri tira me î kore i te unahi. I te wa e whakamahia ana te anneatanga kanapa, kaore e tika te tiki.
