Apiti 40 waro paipa maitai kua whakarōpūtia i runga i te huinga o ngā āhuatanga tae atu i te ōwehenga matotoru diameter-ki-taiepa, kaha rauemi, diameter waho, matotoru pakitara, me te kaha pehanga.
Ko te tohu o te raarangi, penei i te Apiti 40, e whakaatu ana i tetahi huinga motuhake o enei mea. Mo nga paipa Apiti 40, ko te tikanga he ahua te matotoru o te pakitara, he taurite i waenga i te kaha me te taumaha. Ka rereke te taumaha o te paipa i runga i nga ahuatanga penei i te karaehe motuhake o te waro maitai i whakamahia, te diameter me te matotoru o te pakitara.
Ko te taapiri waro ki te rino ka pa ki te taumaha, me te nui ake o te waro ka puta he paipa mama. Heoi, ko te matotoru o te pakitara me te diameter ka whai waahi nui ki te whakatau i te taumaha.
Ko te Apitihanga 40 e kiia ana he karaehe pehanga reo, e tika ana mo nga momo tono e hiahiatia ana nga tohu pehanga ngawari. Mena ka hiahia koe ki etahi atu korero, awhina ranei mo te Apiti 40 paipa waro maitai, tena koa waea mai ki a maatau mo etahi atu awhina.

Apiti 40 waro paipa maitai he tohu rahi paipa paerewa whakamahia i roto i te ahumahi hanga. E pa ana ki te matotoru o te pakitara paipa me tetahi waahanga o te punaha paerewa e whakamahia ana hei whakarōpū i nga paipa i runga i te matotoru o te pakitara me te kaha pehanga.
I roto i te punaha Apiti 40:
- Ko te "Mahere" e pa ana ki te matotoru pakitara o te paipa.
- "Te maitai waro" tohu te hanganga rauemi o te putorino, i te tuatahi te waro me te rino.
Apiti 40 putorino waro maitai e whakamahia nuitia ana mo nga momo tono, tae atu ki te kawe wai me te hau, tautoko hanganga, me nga kaupapa ahumahi. E mohiotia ana mo te kaha, te mauroa, me te whai kiko, na te mea he mea rongonui i roto i te maha o nga kaupapa hangahanga me te miihini.
Te Tito Matū o te Apiti 40 Waro Paipa
