ʻO ka Pipe Kuhili ʻole: He Luʻu hohonu i loko o ka hana ʻana, ka haku ʻana, a me nā noi

I ka hiki ʻana mai i ka honua o nā paipu kila kila, ʻo ka Jindalai Steel Group Co., Ltd. ke kū nei ma ke ʻano he alakaʻi i ka mea hana paipu kila kila. ʻO kā lākou kūpaʻa i ka maikaʻi a me ka hana hou ua lilo lākou i mea pāʻani koʻikoʻi i ka ʻoihana hana paipu kila kila. Akā, he aha ka mea e pono ai nā paipu kila kila ma nā noi like ʻole? Aia ka pane i ka haku mele ʻana o nā ʻano like ʻole o ke kila kila, ka mea e hoʻopilikia nui i ko lākou kūpaʻa corrosion, ikaika, a kūpono no nā hiʻohiʻona kikoʻī.

ʻO ke kila kila he mea hao i haku ʻia me ka hao, ka chromium, a me ka nickel, me nā ʻano mea like ʻole. ʻO ka ʻokoʻa o ka haku mele ʻana ma waena o nā māka like ʻole o ke kila kila hiki ke alakaʻi i nā ʻano like ʻole o ka hana. No ka laʻana, ʻike ʻia nā kila kulika austenitic, aia nā pae kiʻekiʻe o ka nickel, no ko lākou kūpaʻa ʻana i ka corrosion maikaʻi loa. Ma ka ʻaoʻao ʻē aʻe, hāʻawi ka ikaika maikaʻi akā ʻaʻole hiki ke hana maikaʻi ma nā wahi corrosive. He mea koʻikoʻi ka hoʻomaopopo ʻana i kēia mau ʻokoʻa no ke koho ʻana i ka paipu kila kuhiliʻole kūpono no kāu pāhana, inā paha no kahi noi kiʻekiʻe a i ʻole kahi kai moana.

I kēia manawa, e kamaʻilio e pili ana i nā kaʻina hana o nā paipu kila kila. ʻO nā kaʻina hana mua ʻelua he kaʻina hana anuanu a me ka wela, me ka welded (RW/SAW) a me nā ʻenehana hana ʻole. ʻIke ʻia nā paipu i ʻōwili ʻia no ko lākou hoʻopau ʻana i ka ʻili a me ka hoʻomanawanui ʻoi aku ka paʻa, e hoʻolilo iā lākou i mea kūpono no nā noi i mea nui ka aesthetics a me ka pololei. Eia nō naʻe, hiki iā lākou ke ʻoi aku ke kumukūʻai a me ka liʻiliʻi o ka ductile ma mua o ko lākou mau hoa ʻōwili wela. ʻO nā paipu ʻōwili wela, ʻoiai ka liʻiliʻi o ka pololei, ʻoi aku ka maʻalahi o ka hana ʻana a hiki ke mālama i nā anawaena ʻoi aku ka nui, e kūpono ai ia no nā hana hoʻolālā.

ʻO nā paipu welded, i hana ʻia ma o Electric Resistance Welding (ERW) a i ʻole Submerged Arc Welding (SAW), hāʻawi i kahi hopena maikaʻi loa no nā noi he nui. Eia nō naʻe, ʻaʻole kūpono lākou no nā hiʻohiʻona kiʻekiʻe ma muli o nā nāwaliwali hiki ke ma ka weld seam. ʻO ka hoʻohālikelike, hana ʻia nā paipu seamless me ka ʻole o nā hono, e hāʻawi ana i ka ikaika kiʻekiʻe a me ka hilinaʻi, ʻoi aku hoʻi i nā noi kiʻekiʻe a me ka wela. ʻO kēia ka mea e koho ai i nā paipu maʻemaʻe no nā ʻoihana e like me ka aila a me ke kinoea, kahi e hiki ʻole ai ke kūkākūkā ʻia ka palekana a me ka hana.

I ka hopena, ʻokoʻa ka honua o nā paipu kila kila e like me ka mea nui. Hōʻike ka Jindalai Steel Group Co., Ltd. i ka maikaʻi a me ka hana hou i hiki ke loaʻa i ka hana ʻana i ka paipu kila kila. Ma ka hoʻomaopopo ʻana i nā ʻokoʻa o ka haku mele ʻana ma waena o nā māka like ʻole o ke kila kila a me nā pono a me nā hemahema o nā kaʻina hana hana like ʻole, hiki iā ʻoe ke hoʻoholo i ka ʻike no kāu mau papahana. Inā makemake ʻoe i kahi paipu e hiki ke kū i nā kaiapuni ʻoi aku ka paʻakikī a i ʻole ka maikaʻi o ka hoʻolālā ʻana, aia kahi paipu kila kila ma laila no ʻoe. No laila, i ka manawa aʻe e noʻonoʻo ai ʻoe i nā paipu kila kila, e hoʻomanaʻo: ʻaʻole ia e pili ana i ka metala; e pili ana i ka ʻepekema ma hope o ia!
