NA ANO a me na mea e hoohana ai i ka hao ma ka oihana paipu
I ka hoʻololiʻana o nā kaʻina hana hana a lilo i mea paʻakikī, ua hoʻonuiʻia ka kohoʻana o nā mea kūʻai kila e hoʻokō i nā koi kiko'ī he nui i nāʻoihana likeʻole.

Akā ʻaʻole like nā pae kila a pau. Ma ke kālailai ʻana i nā ʻano kila i loaʻa mai nā mea hoʻolako paipu ʻoihana a me ka hoʻomaopopo ʻana i ke kumu e hana ai kekahi mau kila i ka paipu maikaʻi loa a ʻaʻole hana ʻē aʻe, ʻoi aku ka maikaʻi o nā ʻoihana ʻoihana paipu.

HAAWINA KAPONO
Hana ʻia kēia kila ma ka hoʻohui ʻana i ka hao nāwaliwali i ke kalapona. ʻO Carbon ka mea hoʻohui kemika kaulana loa i kahi mea ferrous i ka ʻoihana hou, akā hoʻohana nui ʻia nā mea hoʻohuihui o nā ʻano āpau.

I ka hana ʻana i ka pipeline, ʻo ke kila kalapona ke kila kaulana loa. Mahalo i kona ikaika a me ka maʻalahi o ka hana ʻana, hoʻohana nui ʻia ka paipu kila carbon ma nā ʻano he nui. Ma muli o ka liʻiliʻi o nā mea hoʻohuihui, he haʻahaʻa ke kumu kūʻai o ka paipu kila carbon ma nā haʻahaʻa haʻahaʻa.

Hoʻohana ʻia nā paipu kino kalapona i ka halihali wai, ka aila a me ka lawe ʻana i ke kinoea, nā mea kani, nā kaʻa, nā kaʻa, a me nā mea ʻē aʻe.

HAAWINA HUI
ʻO ke kila kila me nā nui i kuhikuhi ʻia o nā mea hoʻohuihui. Ma keʻano laulā, ʻoi aku ka maikaʻi o ke kūpaʻa o ke kila i ke koʻikoʻi a i ʻole ka hopena. ʻOiai ʻo ka nickel, molybdenum, chromium, silicon, manganese a me ke keleawe ka mea maʻamau o ka alloying element, nui nā mea ʻē aʻe i hoʻohana ʻia i ka hana kila. Hoʻohana ʻia i ka hana ʻana, he nui nā hui pū ʻana o nā alloys a me nā mea hoʻohālikelike, me kēlā me kēia hui i hoʻolālā ʻia e hoʻokō i nā ʻano ʻokoʻa.
Loaʻa ka Alloy Steel Pipe i nā nui ma kahi o 1/8′ a i 20′ a loaʻa nā papa hana e like me S/20 a i S/XXS. I loko o nā ʻaila hinu, nā mea kanu petrochemical, nā mea kanu kemika, nā hale hana kō, a me nā mea ʻē aʻe, hoʻohana pū ʻia nā paipu kila. Hoʻomaikaʻi ʻia nā paipu kila Alloy, hoʻolālā ʻia a hoʻolako ʻia i nā kumukūʻai kūpono e like me kāu mau koi.

KILA KOHU ʻOLE
He ʻino iki kēia ʻōlelo. ʻAʻohe hui like ʻole o nā mea hao a me nā mea hoʻohui i hana ʻia i ke kila kila. Akā, ʻaʻole e pala nā mea i hana ʻia mai ke kila kila.
Hiki ke hoʻohana ʻia ʻo Chromium, silicon, manganese, nickel a me molybdenum i nā ʻāpana kila kila. No ke kamaʻilio ʻana me ka oxygen i ka ea a me ka wai, hana pū kēia mau mea hoʻohui e hana wikiwiki i kahi kiʻiʻoniʻoni lahilahi akā ikaika ma ke kila e pale ai i ka ʻino hou.

ʻO Stainless Steel Pipe ka koho kūpono no nā ʻāpana kahi e pono ai ke kūpaʻa corrosion a koi ʻia ka lōʻihi kiʻekiʻe e like me ka uila moku, nā pou uila, ka mālama wai, ka lāʻau lapaʻau a me nā noi aila a me ke kinoea. Loaʻa ma 304/304L a me 316/316L. ʻO ka mea mua he kūpaʻa kūʻokoʻa a paʻa, ʻoiai ʻo ka ʻano 314 L he haʻahaʻa kalapona haʻahaʻa a hiki ke weldable.
