Roa:
Ko te roa o ngā paipa rino he 4 000 mm ~ 12 000 mm. Whai muri i te kōrerorero a te kaiwhakarato me te kaihoko, me te whakakī i te kirimana, ka taea te tuku i ngā paipa rino he roa ake i te 12 000 mm, he poto ake rānei i te 1 000 mm engari kaua e poto ake i te 3 000 mm; he poto te roa. Ko te maha o ngā paipa rino iti iho i te 4,000 mm engari kaua e iti iho i te 3,000 mm kaua e neke ake i te 5% o te tapeke o ngā paipa rino kua tukuna.
Taumaha tukunga：
Ina tukuna te paipa maitai i runga i te diameter o waho me te matotoru o te pakitara, i te diameter o roto me te matotoru o te pakitara rānei, ka tukuna te paipa maitai i runga i te taumaha tuturu. Ka taea hoki te tuku i runga i te taumaha ariā.
Ina tukuna te paipa rino kia rite ki te whānui o waho me te matotoru iti rawa o te pakitara, ka tukuna te paipa rino kia rite ki te taumaha tuturu; ka whiriwhiria e te hunga tuku me te hunga tono. Ā, kua tohua tēnei i roto i te kirimana. Ka taea hoki te tuku i te paipa rino kia rite ki te taumaha ariā.
Te manawanui taumaha：
E ai ki ngā whakaritenga a te kaihoko, whai muri i te kōrero tahi a te kaiwhakarato me te kaihoko, me roto hoki i te kirimana, me tutuki i te rerekētanga i waenga i te taumaha tuturu me te taumaha ariā o te paipa maitai tuku ngā whakaritenga e whai ake nei:
a) Paipa rino kotahi: ± 10%;
b) Ia puranga paipa maitai me te rahi iti rawa o te 10 t: ± 7.5%.
Whakamātautau Waipūngao:
Me whakamātautau waipēhi te paipa maitai takitahi. Ko te pēhanga whakamātautau mōrahi ko te 20 MPa. I raro i te pēhanga whakamātautau, me kaua e iti iho i te 10 hēkona te wā pumau, ā, kaua hoki te paipa maitai e turuturu.
Kia whakaaetia e te kaiwhakamahi, ka taea te whakakapi i te whakamātautau waipēhi mā te whakamātautau iahiko porotaka, te whakamātautau turuturu rerenga aukume rānei.
Whakamātautau Kore-Whakangaromanga：
Ko ngā paipa e hiahia ana kia tirotirohia anōtia, me tirotirohia takitahi mā te whakamahi i te ultrasonic. Kia whakaaetia te taha e te whiriwhiringa, ā, kua tohua ki roto i te kirimana, ka taea te tāpiri atu i ētahi atu whakamātautau kore-whakangaro.
Whakamātautau Whakapapa
Me whakamātau te whakatārewatanga o ngā ngongo he nui ake i te 22 mm te whānui o waho. Kaua e kitea he wehewehenga, he ira mā, he poke rānei i te roanga o te whakamātautau.
Whakamātautau Mura:
E ai ki ngā whakaritenga a te kaihoko, me te mea kua whakahuatia i roto i te kirimana, ka taea te whakamātautau mura mō te paipa rino he ≤76mm te whānui o waho me te matotoru o te pakitara ≤8mm. I mahia te whakamātautau i te pāmahana rūma me te piko 60°. I muri i te mura, me tutuki te tere mura o te whānui o waho i ngā whakaritenga o te ripanga e whai ake nei, ā, kaua te rauemi whakamātautau e whakaatu i ngā pakaru, i ngā haehae rānei.
