Paipu LSAWhe paipu kila i wiliwili ʻia me ka lōʻihi i hana ʻia me ka hoʻohana ʻana i ka ʻenehana hoʻoheheʻe arc submerged.
Hōʻike ʻia nā paipu kila LSAW e nā welds longitudinal e holo ana i ka lōʻihi holoʻokoʻa o ka paipu, e puka mai ana mai loko a me waho o ka paipu.
ʻO ka maikaʻi o ka paipu kila LSAW ʻo ia ka hiki ke hāʻawi i nā paipu nui-diameter, pā mānoanoa, a me nā paipu kiʻekiʻe.

Ma ka ʻōlelo maʻalahi, ʻo kaLSAWʻO ke kaʻina hana e pili ana i ka wili ʻana i nā pā kila i loko o ke ʻano o ka paipu a laila e hoʻohana i ka wili arc submerged e hoʻopaʻa i nā ʻaoʻao o nā papa kila a lilo i paipu kila.
Ma hope aʻe, e alakaʻi mākou iā ʻoe ma nā ʻanuʻu koʻikoʻi i ka hana ʻana i nā paipu kila LSAW, e hāʻawi iā ʻoe i kahi ʻike maopopo o ke kaʻina hana.
1. Ka nānā ʻana a me ka ʻoki ʻana i ka pā: Ma muli o nā kūlana hoʻokō o ka paipu kila a me nā ana i koi ʻia, e ʻoki ʻia nā papa kūpono i nā nui kūpono.
2. Ka wili lihi: E hana i ka lihi o ka paipu kila e hana i ke ano kupono no ka wiliwili ana, e like me ke ano V.He mea koʻikoʻi kēia ʻanuʻu no ka maikaʻi o ka weld.
3. Hookumu ana: Ke hoʻohana nei kā mākou hui i ke kaʻina hana JCOE, kahi i hoʻokumu ʻia ai ka pā kila i kahi ʻano tubular mau e nā wili a me kahi paʻi.
4.wiliwili: I loko o ka hili longitudinal o ka hale tubular, hana ʻia ke kuʻi ʻana i loko o ka pahu e hoʻohui i nā ʻaoʻao o nā papa kila e hana i ka paipu kila.ʻO kēia ka pae koʻikoʻi loa i ka hana holoʻokoʻa.
5. Nānā: ʻO ka nui o nā nānā, me ka 100% non-destructive testing a me ka hydrostatic leak testing o nā paipu kila, e hōʻoia i ka hoʻokō ʻana o ka huahana i nā koi maʻamau.
Ma ke kaʻina hana maoli o nā paipu kila LSAW, ma waho aʻe o nā kaʻina hana nui i ʻōlelo ʻia ma luna, he nui nā ʻanuʻu maikaʻi a paʻakikī.Pono kēia mau ʻanuʻu i ka mana pololei a me ka nānā pono ʻana i ka maikaʻi e hōʻoia i ka hana ʻana o nā paipu kila LSAW kiʻekiʻe e kūpono i nā kūlana.
1. Hiki ke hoʻololi: Hoʻohana pinepineʻia nā paipu kila LSAW i nā wahi hana kiʻekiʻe a me ke kiʻekiʻe.Me ka uhi kūpono, hiki i kēia mau paipu ke mālama i ka hana hilinaʻi ʻoiai i ka piʻi ʻana a me nā kūlana geological paʻakikī.
2. Ka maikaʻi o ka welding: I ka hana ana o LSAW, kawiliwili ʻaoʻao ʻelua ʻaoʻao arc (DSAW)hoʻohana ʻia ke kaʻina hana.ʻO kēia kaʻina hana e hōʻoia i ka hoʻokomo pihaʻana o ka weld, no laila e loaʻa ai kahi kūlana kiʻekiʻe o ka maikaʻi o ka welding.ʻO ka weld heʻaʻahu a paʻa, hoʻonui i ka hana holoʻokoʻa a me ka hilinaʻi o ka paipu kila.
3. Paipu kila mānoanoa nui anawaena:
| Nā pōkole | Inoa | Anawaena waho | Mānoanoa Pā |
| SSAW (HSAW, SAWH) | Kuʻiʻo Spiral Submerged Arc | 200 - 3500 mm | 5 - 25 mm |
| LSAW (SAWL) | Welding Arc Submerged Longitudinal | 350 - 1500 mm | 8 - 80 mm |
| ERW | Uila Kū'ē | 20 - 660 mm | 2 - 20 mm |
| SMLS | ʻAʻole ka lau | 13.1 - 660 mm | 2 - 100 mm |
E like me ka mea i ʻike ʻia mai ka hoʻohālikelike ʻana i ka nui o ka hana ma luna, ʻike ʻia nā pono o nā paipu kila LSAW i ka hana ʻana i nā paipu kila mānoanoa nui, e hālāwai ana i nā pono o nā papahana nui a me nā noi ʻoihana.
4. Hoʻohana nui ʻia: Hoʻohana nui ʻia nā paipu kila LSAW i ka hoʻoili ʻana i ka aila a me ke kinoea, ka ʻenekinia hana, ke kūkulu ʻana i ke alahaka, a me nā māla ʻē aʻe e koi ana i nā paipu kila ikaika ma muli o ko lākou ikaika kiʻekiʻe a me ka hana maikaʻi loa.

Ma waho aʻe o nā kūlana paipu kila maʻamau i heluʻia ma luna nei,ʻo ka mea a me ke kūlana o ka pā kila, e like me SS400, ke komo pū nei i ka hanaʻana i nā paipu kila me ka hoʻohanaʻana i ke kaʻina hana LSAW.ʻAʻole lākou i helu ʻia ma ʻaneʻi.
Hoʻopili pinepine ʻia nā ʻili o loko a me waho o nā paipu kila LSAW e kūpono i nā ʻano hana like ʻole.
Hiki i kēia mau pale ke lilo i mau pale pale no ka manawa lōʻihi a i ʻole nā pale anti-corrosion lōʻihi.Loaʻa nā ʻano uhi maʻamaupena, galvanization, 3LPE, FBE,TPEP, epoxy coal tar, etc.
Mālama maikaʻi kēia mau uhi i nā paipu kila mai ka corrosion, hoʻonui i ko lākou ola lawelawe, a hōʻoia i ko lākou kūpaʻa a me ka hilinaʻi ma lalo o nā kūlana kaiapuni.
ʻO ka paipu kila LSAW he mea waiwai nui.I mea e hōʻoiaʻiʻo ai i kona holo ʻana ma nā mākeke ʻāina a me nā ʻāpana ʻē aʻe, pono e kiʻi ʻia ka paipu kila LSAW i nā palapala hōʻoia i ka wā e lawe mai ai a hoʻokuʻu aku.Aia nā mea maʻamauAPI 5L hōʻoia,ISO 9001 palapala hōʻoia,ISO 19001 palapala hōʻoia, ISO 14001 palapala hōʻoia,a ISO 45001 palapala hōʻoia.
