ʻO ka ʻoiaʻiʻo, ʻaʻole poepoe loa nā paipu ʻoihana, a he mea maʻamau kēia kūlana. ʻO nā kumu nui penei: Hana ʻia nā paipu kila humuhumu ʻoihana ma o ka ʻōwili anu a i ʻole ke kīkoʻo wela. ʻO ke anawaena o ka paipu maʻamau a hiki i ka ≤DN2000, a ʻae ʻia kahi hewa ovality. Eia kekahi, pili loa ka ovality o nā paipu kila i ka hana ʻia ʻana e nā ʻoihana kila nui a i ʻole nā ʻoihana kila liʻiliʻi, me nā ʻano like ʻole. He liʻiliʻi loa ka ovality o nā paipu kila branded, ʻoiai ʻo nā paipu kila ʻaʻohe branded he haʻahaʻa loa. No kekahi mau paipu kila DN300, hiki i ka hewa diameter kiʻekiʻe ke hiki i ka 5mm. Ma waho aʻe o nā paipu kila humuhumu, he nui nā pipelines i hoʻohana ʻia no ka lawe ʻana i ka wai haʻahaʻa haʻahaʻa he mau paipu wili wili. ʻOi aku ka ʻino o kā lākou helu ovality ma mua o nā paipu kila humuhumu i hana ʻia me ka mīkini. Pono mākou e makaʻala i kēia mau kūlana i ka wā e hoʻohana ai i kēia mau paipu no nā kumu ana. ʻAʻohe hopena o ka ovality o nā paipu kila i ka lawe ʻana i nā wai i ke kaʻina hana o ka hana ʻoihana. Eia nō naʻe, i ka wā e pili ana i nā noi ana o ke kahe ʻana, e like me ka hoʻopaʻa ʻana i waho a me ka hoʻokomo ʻana i nā mika kahe ultrasonic a i ʻole nā mea hana kahe ʻano hoʻokomo ʻē aʻe, inā koʻikoʻi ka ʻokoʻa ovality, e loaʻa iā ia kahi hopena. I ka wā e hoʻokomo ai ma kahi, pono e uku ʻia ka nānā ʻana i ke koho ʻana i kahi ʻāpana o ka pipeline me nā kūlana maikaʻi aʻe.
