Ko te "" te tohu i te diameter o te porowhita noa, te diameter o waho ranei o te paipa kua whakareatia ki te matotoru o te pakitara, penei: φ25×3 tohu te diameter o waho
Paipa 25mm me te 3mm te matotoru pakitara;"DN": ingoa ingoa mo nga taputapu penei i nga paipa me nga maru
Ara, te nuinga o te tata ki te diameter o roto.He tikanga paerewa kua whakapumautia mo te kaupapa o nga whakaurunga whakaurunga miihini.
Ko te tikanga ko te diameter o waho, ko te DN e tohu ana ki te diameter o roto DN: diameter ingoa: diameter o waho
Inaianei nga ngongo- -.penei i roto i te inihi, he tata noa te mitamano, he ngawari ki te mahara ki te nama.
Hei tauira, me 2 inihi te paipa DN50, 1 inihi =25.4mm, 2 inihi me 50mm,
I tenei wa, ko te matotoru o te pakitara o te putorino, ko te paipa torino kei runga ake i te 5mm, me te 5mm hei tauira,
Ko te diameter o waho o te ngongo DN50 me 60mm.
