Paipu LSAW (Longitudial Submerged Arc Welding)
LSAW (Longitudinal Submerged Arc Welding):ʻO kēia ke ʻano o ke kaʻina hana.
Longitudinal: Holo like ke kuʻina wili i ka lōʻihi o ka paipu (ma kahi laina pololei). He ʻokoʻa kēia mai ka HSAW/SSAW (Helical/Spiral Submerged Arc Welding), kahi he wili ka wili.
Kuʻihao Arc i Hoʻoheheʻe ʻia (SAW): He hana kuʻihao kiʻekiʻe kahi e hoʻoluʻu ʻia ai ke arc ma lalo o kahi papa o ka flux fusible. ʻAe kēia i ka komo ʻana o ka wela hohonu, hana i kahi kuʻihao ikaika loa a like, a hana i kahi ʻano laumania me ka ʻole o ka pīpī.
ʻAoʻao pālua o ke kuʻi pololei:Hōʻike kēia i ke ʻano kino o ka weld.
Hoʻokumu ʻia ka paipu mai kahi papa kila hoʻokahi (skelp) i ʻōwili ʻia i loko o kahi cylinder, e hana ana i hoʻokahi humuhumu pololei.
ʻAoʻao Pālua: Hana ʻia ka wili ʻana ma loko a ma waho o ka paipu. He mea koʻikoʻi kēia no ka mea e hōʻoiaʻiʻo ana i ke kūpaʻa o ka wili ʻana he kiʻekiʻe loa, e hiki ai ke lawelawe i nā kaomi kiʻekiʻe a me nā noi koi.

| Nā Wāhi Paipu | Nā wēlau Beveled me a i ʻole me ka ʻole o nā pale kila hopena paipu |
| ʻIli Paipu | ʻEleʻele kūlohelohe a i ʻole pena ʻia ʻEleʻele a i ʻole 3PE i uhi ʻia |
Nā Hoʻohana Nui o nā Paipu Kila LSAW
| Māhele Noi | Nā Hoʻohana Kūikawā | No ke aha i hoʻohana ʻia ai ka LSAW |
| Nā Paipu ʻAila a me ke Kinoea ma uka/ma waho o ka ʻāina | Nā paipu hoʻoili no ka ʻaila maka, ke kinoea kūlohelohe, a me nā huahana i hoʻomaʻemaʻe ʻia. | Hoʻokele i nā kaomi kūloko kiʻekiʻe loa, kū i nā pilikia o waho, a hiki ke uhi ʻia no ka pale ʻana i ka pala i nā wahi ʻino. |
| Nā lawelawe kaomi kiʻekiʻe | ʻO ka mahu kaomi kiʻekiʻe, nā laina hānai kemika, a me ka lawe ʻana i ka slurry. | Hiki i ke kūkulu paʻa ke kū i ke kaumaha mau a koʻikoʻi me ka ʻole o ka hāʻule ʻana. |
| Nā Hana Kai a me nā Hana Piling | Ke kūkulu ʻana i nā pou kumu no nā alahaka, nā awa, a me nā kahua ma waho o ke kai. | ʻO ke anawaena nui a me nā paia mānoanoa e hāʻawi i ke kākoʻo kūkulu nui a me ka hiki ke hāpai i nā ukana. Hoʻokomo pinepine ʻia lākou i loko o ka lepo. |
| ʻEnekinia Kīwila a me ke Kūkulu ʻana | Nā kolamu kūkulu no nā hale kiaʻi kiʻekiʻe, nā kahua pāʻani, a me nā hale nui. | Hoʻohana ʻia e like me nā "kolamu paipu" i hoʻopiha ʻia me ka sima (CFST) e hāʻawi i ka ikaika a me ke kūpaʻa kupaianaha i ke ʻano kumu. |
| Hoʻoili Wai | Nā paipu wai nui a me nā ʻōmole wai no nā mea kanu mana hydroelectric. | Hiki ke hoʻoneʻe i nā wai he nui ma lalo o ke kaomi kiʻekiʻe. |
Nā Palapala Hōʻoia Paipu Kila LSAW
- ʻŌnaehana HSE ISO9001 & ISO14001 & ISO45001.
- API Spec 5L me ka lawelawe Sour no ka linepipe.
- Ka māka ʻana o CE no ka paipu EU CPR&PED.
- ISO17025 no ka hale hoʻokolohua.
Papa inoa ʻae ʻia nā paipu kila LSAW
ʻO ADNOC a me nā EPC he nui ma ka home a ma waho.
Ka Mana Hoʻokele Kūlana o nā Paipu Kila LSAW
Ua hoʻokumu ʻia kā mākou keʻena hoʻokolohua e like me nā koi CNAS a me API 5L PSL2.
- Hoʻāʻo kemika
- Hoʻāʻo tensile
- Ka hoʻāʻo hopena CVN max -70°C
- Hoʻāʻo DWT max -60°C
- Hoʻāʻo metallographic
- Hoʻāʻo paʻakikī
- Hoʻāʻo ʻana i ka uhi ʻana
Ua kūkulu mākou i kahi ʻōnaehana traceability e huli i kēlā me kēia paipu mai ka pā a i ka paipu i hoʻopau ʻia me ka helu paipu a mālama i ka moʻolelo no ka liʻiliʻi he 2 mau makahiki.
No ke aha i koho ʻia ai nā paipu LSAW no nā noi kiʻekiʻe
Ka helu ʻana o ka ikaika a me ke kaomi kiʻekiʻe:Hoʻokumu ke kaʻina hana SAW ʻelua ʻaoʻao i kahi wili i ʻoi aku ka ikaika e like me, a ʻoi aku paha ka ikaika ma mua o, ke kila kumu ponoʻī. ʻO kēia ka mea e kūpono ai lākou no nā noi kaomi kiʻekiʻe.
Nā Anawaena Nui a me nā Paia Mānoanoa:Hiki ke hana ʻia nā paipu LSAW i nā anawaena nui loa (maʻamau mai 16 ʻīniha a hiki i 60 ʻīniha a ʻoi aku paha) a me nā paia mānoanoa loa, kahi mea hiki ʻole ke hana ʻia me nā kaʻina hana paipu liʻiliʻi e like me ka ERW (Electric Resistance Welding).
Ka pololei o ke ana ʻana maikaʻi loa:He kūlike loa ko lākou ana a me ke poepoe, he mea nui ia no ke kūkulu ʻana i nā paipu a me nā papahana kūkulu.
Kūpono no nā uhi:ʻO ko lākou humuhumu pololei a me ka ʻili laumania e kūpono loa ai no ka hoʻopili ʻana i nā uhi pale like ʻole (e like me FBE Fusion Bonded Epoxy, 3LPE/3LPP) a me nā uhi (e like me, ka uhi kaumaha sima no nā paipu kai). ʻO kahi ʻili laumania a kūlike e hōʻoiaʻiʻo ana i ka pipili pono ʻana o ka uhi a hana i kāna hana pale.
