Ke hoʻolauna nei i kā mākou paipu spiral-seam kiʻekiʻe, kahi huahana e hoʻokomo i ka ikaika, ka lōʻihi a me ka ʻenekinia pololei. Hana ʻia me ka hoʻohana ʻana i kahi kaʻina wiliwili spiral holomua, ua hana ʻia kā mākou mau paipu mai nā wili kila wela i hana ʻia i loko o ke ʻano cylindrical a hoʻopaʻa ʻia ma ke kaʻina spiral. ʻAʻole kēia ʻenehana hana hou e hoʻonui i ka paʻa o nā paipu, akā e hōʻoiaʻiʻo nō hoʻi e hiki iā lākou ke pale i nā noi koi loa.

Ma kā mākou hui, haʻaheo mākou iā mākou iho i kā mākou kūpaʻa kūpaʻa ʻole i ka ʻoluʻolu o ka mea kūʻai aku. I loko o nā makahiki, ua kūkulu mākou i kahi kaulana no ka maikaʻi ma o ka hoʻokumu ʻana i nā pono o kā mākou mea kūʻai aku i kēlā me kēia manawa o ke kaʻina kūʻai. Mai ka kūkākūkā mua o ke kūʻai aku i ke kākoʻo kūʻai aku a me nā lawelawe ma hope o ke kūʻai aku, ua kūpaʻa mākou e hālāwai i nā pono āpau o kā mākou mea kūʻai.

FAQ

Q1: He aha ka spiral seam pipe?

Hoʻokumu ʻia ka paipu spiral seam me ka hoʻohana ʻana i kahi ala kūikawā i kapa ʻia ʻo ke kaʻina hana hoʻoheheʻe spiral. ʻO kēia ʻenehana hou e pili ana i nā wili kila ʻōwili wela e hana ʻia i ke ʻano cylindrical a hoʻopaʻa ʻia me kahi wili spiral. ʻO ka paipu hopena ʻaʻole wale ka ikaika kiʻekiʻe akā ke kūpaʻa maikaʻi nō hoʻi, e kūpono ana ia no nā ʻano noi like ʻole, me ka lawe ʻana i ka aila a me ke kinoea, ka lako wai a me ke kākoʻo kūkulu.

Q2: No ke aha e koho ai i ke kiʻekiʻe kiʻekiʻe spiral seam paipu?

ʻO ka pōmaikaʻi nui o nā paipu seam kiʻekiʻe kiʻekiʻe ʻo kā lākou hana ikaika. ʻO ke kaʻina hana hoʻoheheʻe spiral e hiki ai ke hoʻomau i ka wili, e hoʻonui ai i ka pono a me ke kūpaʻa paʻa o ka paipu. Eia kekahi, hiki ke hana ʻia kēia mau paipu i nā ʻano nui a me nā mānoanoa e hoʻokō i nā pono kikoʻī o nā papahana like ʻole.

Q3: He aha kaʻu e ʻimi ai i kahi mea hoʻolako?

Ke koho ʻana i kahi mea hoʻolako spiral seam tubing, he mea koʻikoʻi ke koho ʻana i kahi ʻoihana e kau mua i ka ʻoluʻolu o ka mea kūʻai aku. E ʻimi i kahi mea hoʻolako e hāʻawi ana i nā lawelawe kūʻai mua, kūʻai, a ma hope o ke kūʻai aku. E hōʻoia ka ʻoihana kaulana e hoʻokō kāna mau huahana i nā kikoʻī i hoʻokumu ʻia a hiki ke hoʻokō i kāu mau koi kūikawā, e hōʻoia ana e loaʻa iā ʻoe nā huahana kiʻekiʻe a me nā lawelawe e mahalo ai kāu mea kūʻai.
