Roa:
Ko te roa o nga paipa maitai he 4 000 mm ~ 12 000 mm.Whai muri i te Whakawhitiwhitinga i waenganui i te Kaituku me te Kaihoko, me te whakakii i te kirimana, ka taea te tuku paipa rino me te roa nui atu i te 12 000 mm ranei te poto ake i te 000 mm engari kaua e poto ake i te 3 000 mm;Te Roa Poto Ko te maha o nga paipa rino iti iho i te 4,000 mm engari kaua e iti iho i te 3,000 mm kaore e neke ake i te 5% o te tapeke o nga paipa rino ka tukuna.
Taumaha Tukunga:
I te wa e tukuna ai te paipa rino kia rite ki te diameter o waho ingoa me te matotoru o te pakitara whakaingoa, ki te rahi ranei o roto me te matotoru o te pakitara ingoa, ka tukuna te paipa rino kia rite ki te taumaha.Ka taea hoki te tuku i runga i te taumaha o te whakaaro.
I te wa e tukuna ai te paipa rino kia rite ki te diameter o waho ingoa me te matotoru o te pakitara iti rawa, ka tukuna te paipa rino kia rite ki te taumahatanga tuturu;Ka Whakawhitiwhiti Nga Roopu Tuku Me Te Tono.A kua tohuhia i roto i te kirimana.Ka taea hoki te tuku i te paipa rino i runga i te taumaha o te whakaaro.
Whakaaetanga Taumaha:
E ai ki nga Whakaritenga a te Kaihoko, I muri i te Whakawhitiwhitinga i waenganui i te Kaituku me te Kaihoko, i roto hoki i te kirimana, ko te wehe ke i waenga i te taumaha tuturu me te taumahatanga o te paipa rino tuku ka tutuki nga whakaritenga e whai ake nei:

Whai muri i te whakaae a te Kaiwhakamahi, ka taea te whakakapi i te whakamatautau Hydraulic e te whakamatautau o naianei a Eddy o naianei, ki te whakamatautau ranei i te rerenga rerenga aukume.
Whakamātautau kore kino:
Ko nga paipa e hiahia ana kia nui ake te tirotiro me tirotirohia e te Ultrasonically takitahi.I muri i te Whakawhitiwhitinga Me Te Whakaaetanga a te Roopu Ka Whakatakotoria I Te Kiriata, Ka Taea Te Apiti Atu I etahi atu Whakamatau Whakamate-kore.
Whakamātautau Whakapapa:
Ko nga ngongo me te diameter o waho ka nui ake i te 22 mm ka tukuna ki te whakamatautau papatahi.Karekau he whakamomori, he wahi ma, he poke ranei i te wa o te whakamatautauranga katoa.
Whakamātautau mura:
E ai ki nga Whakaritenga a te Kaihoko me te korero i roto i te kirimana, ko te paipa rino me te diameter o waho ≤76mm me te matotoru o te pakitara ≤8mm ka taea te mahi i te whakamatautau mura.I mahia te Whakamātautau i te pāmahana rūma me te 60 °.Whai muri i te Whakamutunga, Me tutuki te tere o te mura o te diameter o waho ki nga whakaritenga o te ripanga e whai ake nei, a, kaua e whakaatuhia e te mea whakamatautau he kapiti, he pakaru ranei.
