Paipu Piula Seam Pipe No na Paipu Wai Malalo
ʻO kapaipu wai ma lalo o ka honuahe paipu kila wiliwili i hana ʻia e ke kaʻina hoʻoheheʻe ʻia ʻana o nā uea ʻelua ʻaoʻao lua.Hana ʻia ka paipu mai nā wili kila a hoʻokuʻu ʻia i kahi mahana mau e hōʻoia i kona paʻa a lōʻihi.

ʻO ke kūkulu ʻia ʻana o ka paipu i hui pū ʻia e hōʻoia i ka ikaika loa a me ka pale ʻana i ke kaomi, e lilo ia i koho kūpono no nā ʻōnaehana wai lalo.
Ma waho aʻe o ka ikaika a me ka lōʻihi, ua hoʻolālā ʻia nā paipu wai lalo no ka maʻalahi o ka hoʻokomo ʻana.Hiki ke maʻalahi a hiki ke hoʻololi ʻia ke kūkulu ʻana i ka spiral seam.ʻO ia ke ʻano hiki iā ʻoe ke waiho i nā paipu me ka wikiwiki a me ka maikaʻi, e mālama i ka manawa a me nā koina hana.
Eia kekahi, ʻo ka hoʻohana ʻana i nā mea kiʻekiʻe kiʻekiʻe a me ka ʻenehana welding kiʻekiʻe e hōʻoia i ka pale ʻana o nā paipu wai i lalo i ka corrosion a me ka ʻōpala.ʻO ia ka mea e mālama i kona kūpaʻa a me kāna hana no nā makahiki, ʻoiai i nā kūlana lalo o ka honua.
Loaʻa kā mākou mau paipu wai lalo i nā ʻano nui e hoʻokō i nā pono kikoʻī o kāu papahana.Inā ʻoe e waiho nei i kahi wai wai liʻiliʻi a i ʻole kahi ʻōnaehana ʻoihana nui, loaʻa iā mākou ka paipu kūpono no ʻoe.Hiki i kā mākou hui loea ke hāʻawi i nā ʻōlelo aʻo a me ke kākoʻo e kōkua iā ʻoe e koho i nā paipu i kūpono i kāu mau koi.
I ka wā e pili ana i nā ʻōnaehana wai lalo, pono ʻoe i kahi paipu hiki iā ʻoe ke hilinaʻi.Me ke kūkulu ʻana i ka hui spiral kiʻekiʻe, nā mea maikaʻi a me ka hoʻoheheʻe loea, kūpono kā mākou paipu wai lalo no kēlā me kēia ʻoihana wai.Paʻa, hilinaʻi a maʻalahi hoʻi e hoʻokomo, e kū kēia paipu i ka hoʻāʻo o ka manawa, e hāʻawi iā ʻoe i ka maluhia o ka noʻonoʻo a me ka hana ʻoi aku ka maikaʻi.
ʻO nā mea a pau, he koho maikaʻi loa nā paipu seam spiral no kēlā me kēia mea e makemake i kahi hopena hoʻohele wai kiʻekiʻe, hilinaʻi a paʻa.Me kona kūkulu ʻana i nā wili spiral holomua a ʻoihanawili paipu metala, hāʻawi ka paipu i ka ikaika like ʻole, ka maʻalahi a me ka pale ʻana i ka corrosion.Mai hoʻololi i ka maikaʻi o kāu ʻōnaehana wai lepo – e koho i nā paipu wai ma lalo o ka honua i mea e hiki ai iā ʻoe ke hilinaʻi.
