He aha nā hoʻohālikelike o nā paipu wili lōʻihi ma muli o nā ʻano welding?
Nā paipu wiliwili lōʻihi ua hoʻokaʻawale ʻia ma muli o nā ʻano welding i hoʻohana ʻia i kā lākou hana. Loaʻa i kēlā me kēia ala kona mau hiʻohiʻona a me nā mea maikaʻi, e kūpono iā lākou no nā noi like ʻole. E ʻimi kākou i nā papa helu nui:
1. Longitudinal Submerged Arc Welded (LSAW) Paipu
Hana ʻia nā paipu LSAW me ka hoʻohana ʻana i ke kaʻina hana hoʻoheheʻe arc submerged, kahi i pale ʻia ai ke arc welding a me ka metala hoʻoheheʻe ʻia e kahi papa o ka flux granular. Hoʻopuka kēia ʻano hana i nā welds kiʻekiʻe me nā ʻano mīkini maikaʻi loa a kūpono loa i nā paipu pā mānoanoa nui.
ʻO nā hiʻohiʻona nui o nā paipu LSAW:
- Ka ikaika kiʻekiʻe a me ka paʻakikī
- Maikaʻi weld maikaʻi
- He kūpono no nā noi kiʻekiʻe
- Ka laulā nui (maʻamau 16" a 60")
Hoʻohana nui ʻia nā paipu LSAW i nā pipeline hoʻouna ʻaila a me ke kinoea, nā kahua o waho, a me nā noi kiʻekiʻe.
2. Uila Kū'ē Welded (ERW) Paipu
Hana ʻia nā paipu ERW ma ka hoʻokuʻu ʻana i ke au uila ma nā ʻaoʻao o ke kaula kila, a laila hana pū ʻia ma lalo o ke kaomi. ʻO kēia ʻano hana maikaʻi a maikaʻi hoʻi, e hana ana i nā paipu ERW i kaulana no nā noi like ʻole.
ʻO nā hiʻohiʻona o nā paipu ERW:
- Mānoanoa pā like
- ʻO ka pololei o ke ana ʻana
- He kūpono no nā noi haʻahaʻa
- Loaʻa maʻamau i nā anawaena liʻiliʻi (a hiki i 24")
Hoʻohana mau ʻia nā paipu ERW i nā ʻōnaehana lako wai, nā noi hoʻolālā, a me nā laina haʻahaʻa haʻahaʻa a me nā laina ʻaila.
3. Nā Paipu Kūleʻa Paʻa ʻelua (DSAW).
Hana ʻia nā paipu DSAW me ka hoʻohana ʻana i ke kaʻina hana kuʻekuʻe ʻelua. Hoʻopili mua ʻia ka paipu mai kekahi ʻaoʻao me ka hoʻohana ʻana i ke ʻano hoʻoheheʻe arc submerged, a laila huli a wili ʻia mai kēlā ʻaoʻao. Mālama kēia ʻenehana i ke komo piha a me ka maikaʻi weld kiʻekiʻe.
ʻO nā pōmaikaʻi o nā paipu DSAW:
- Ka ikaika weld maikaʻi
- He kūpono no nā paipu pā mānoanoa
- ʻO ka hilinaʻi kiʻekiʻe i nā kaiapuni koi
- Hiki ke hana ʻia ma nā anawaena nui
Hoʻohana pinepine ʻia nā paipu DSAW i nā pipeline o waho, nā laina hoʻoili kiʻekiʻe, a me nā noi hana e koi ana i ka maikaʻi weld kiʻekiʻe.
He aha nā noi ʻoihana o nā ʻano like ʻole o nā paipu wili lōʻihi lōʻihi?
Loaʻa nā paipu wili wili lōʻihi i nā noi ma nā ʻoihana like ʻole ma muli o ko lākou versatility a me ka hilinaʻi. E ʻimi kākou i kekahi mau noi ʻoihana koʻikoʻi no nā ʻano like ʻole paipu wiliwili lōʻihi:
1. ʻOihana ʻaila a me ke kinoea
ʻO ka ʻāpana aila a me ke kinoea kekahi o nā mea kūʻai mua i nā paipu wili lōʻihi. Hoʻohana ʻia nā ʻano like ʻole e pili ana i nā koi kikoʻī:
- LSAW Pipes: Hoʻohana ʻia no nā paipu hoʻouna kiʻekiʻe, ma uka a ma waho.
- ERW Pipes: Hoʻohana ʻia ma ka hōʻiliʻili ʻana i nā laina a me nā pūnaewele hoʻolaha no ka aila a me ke kinoea.
- Nā Paipu DSAW: Hoʻohana ʻia ma nā kahua o waho a me nā paipu subsea kahi mea koʻikoʻi ka ikaika kiʻekiʻe a me ka hilinaʻi.
Hoʻolālā ʻia kēia mau paipu no ka pale ʻana i nā kaomi koʻikoʻi, nā mahana, a me nā wahi ʻino i ʻike pinepine ʻia i nā hana aila a me ke kinoea.
2. Ka wai a me ka wai ʻino
He kuleana koʻikoʻi nā paipu wili wili lōʻihi i ka ʻoihana wai:
- ʻO nā paipu ERW: Hoʻohana nui ʻia i nā ʻōnaehana hoʻolako wai kūloko a me nā ʻupena irrigation ma muli o ko lākou kumukūʻai kūpono a me ka hilinaʻi.
- LSAW Pipes: Hoʻohana ʻia i loko o nā papahana hoʻoili wai nui kahi e koi ʻia ai ke kūpaʻa kiʻekiʻe.
ʻO ke kūpaʻa ʻana o ka corrosion a me ka lōʻihi o kēia mau paipu i kūpono no nā hoʻonā hoʻokele wai lōʻihi.
3. Nā Hana Hana a me nā Hana Hana
Ke hilinaʻi nui nei ka ʻoihana kūkulu i nā paipu wili wili lōʻihi no nā ʻano hana like ʻole:
- ERW Pipes: Hoʻohana ʻia i ka scaffolding, fencing, a me ka hana hoʻolālā māmā.
- LSAW Pipes: Hoʻohana ʻia i nā hana hoʻolālā koʻikoʻi e like me ke kūkulu ʻana i ke alahaka a me nā hale kiʻekiʻe.
- Nā Paipu DSAW: Hoʻohana ʻia i nā papahana ʻoihana nui e koi ana i nā paipu me ka ikaika weld kiʻekiʻe.
Hāʻawi kēia mau paipu i ka ikaika a me ka paʻa pono no nā papahana kūkulu like ʻole.
4. Mahele ikehu
Ma waho aʻe o ka aila a me ke kinoea, he mea koʻikoʻi nā paipu wili wili lōʻihi i nā noi ikehu ʻē aʻe:
- LSAW a me DSAW Paipu: Hoʻohana ʻia i nā mea kanu hydroelectric no nā penstocks a i nā mea mana wela no nā laina mahu.
- ERW Pipes: Hoʻohana ʻia i nā mea kanu mana o ka lā no ke kākoʻo ʻana i ke kūkulu ʻana a me ka halihali wai.
ʻO ka versatility o kēia mau paipu he mea nui ia i nā ʻano hana ikehu a me nā ʻōnaehana hoʻoili.
He aha nā ʻano hana hoʻomalu maikaʻi no nā ʻano like ʻole o nā paipu wili lōʻihi lōʻihi?
ʻO ka hōʻoia ʻana i ka maikaʻi o nā paipu wili wili lōʻihi he mea koʻikoʻi no kā lākou hana a me ka lōʻihi. Ma Longma Group, hoʻokō mākou i nā ana hoʻomalu maikaʻi i loko o ke kaʻina hana. Eia kekahi mau hana hoʻomalu maikaʻi no nā ʻano like ʻole o nā paipu wili lōʻihi.
1. Nānā Mea Maka
Hoʻomaka ka maikaʻi o ka huahana hope me nā mea maka. No na ano a pau paipu wiliwili lōʻihi, hana mākou i ka nānā pono ʻana i nā wili kila a i ʻole nā papa i hoʻohana ʻia:
- Ke kālailai haku mele 'ana e hō'oia i ka ho'okō 'ana i nā māka i kuhikuhi 'ia
- ʻO nā ho'āʻo waiwai mīkini, me ka ikaika hoʻohua a me ka ikaika tensile
- Nānā maikaʻi o ka ʻili e ʻike i nā hemahema
Kōkua kēia mau nānā ʻana i ka hōʻoia ʻana e hoʻokō ka mea kumu i nā kūlana i koi ʻia no ka hana ʻana i nā paipu kiʻekiʻe.
2. Hoʻomalu kaʻina hana welding
He mea koʻikoʻi ke kaʻina hana wili i ka hoʻoholo ʻana i ka maikaʻi o nā paipu wili lōʻihi. Pono nā ʻano paipu like ʻole i nā ana mana kūikawā:
- LSAW Pipes: Ka nānā mau ʻana i nā ʻāpana wili e like me ka manawa, ka uila, a me ka wikiwiki o ka huakaʻi. Nānā mau i ka maikaʻi o ka flux a me ka nui o ka hānai uea.
- ʻO nā paipu ERW: Ka mana pololei o ka pale uila a me ke kaomi ʻana. Ke nānā mau nei i ka wela weld.
- Nā Paipu DSAW: Hoʻopololei pono i nā welds o loko a me waho. Ka hoomalu ana i ka wela waena a me ke kaʻina wiliwili.
ʻO nā lako wiliwili kiʻekiʻe me nā hiki ke nānā pono i ka manawa maoli e hōʻoia i ka maikaʻi o ka weld.
3. Ho'āʻo ʻAʻole Hoʻopōʻino (NDT)
Ma hope o ke kuʻi ʻana, e hoʻāʻo ʻia nā ʻano paipu wili lōʻihi a pau e hōʻoia i ka pono o ka weld:
- ʻO ka Ultrasonic Testing (UT): ʻIke i nā hemahema o loko o ka weld a me ke kino paipu.
- Hōʻike Radiographic (RT): Hāʻawi i nā hōʻike ʻike o ka maikaʻi weld a ʻike i nā hemahema.
- Mākēneki Particle Inspection (MPI): ʻIke i ka ʻili a me nā hemahema kokoke i ka ʻili i nā mea ferromagnetic.
Kōkua kēia mau ho'āʻo e ʻike i nā hemahema e hiki ke hoʻololi i ka hana a i ʻole ka palekana o ka paipu.
4. Ho'āʻo Hydrostatic
ʻO nā paipu wili lōʻihi lōʻihi a pau e hoʻāʻo hydrostatic e hōʻoia i ko lākou hiki ke hoʻopaʻa ʻia:
- Hoʻopiha ʻia nā paipu i ka wai a kaomi ʻia i kahi kiʻekiʻe ma luna o kā lākou hana i hoʻolālā ʻia.
- Mālama ʻia ke kaomi no kahi manawa i ʻike ʻia e nānā i nā leaks a i ʻole deformation.
- Hōʻole ʻia nā paipu i hāʻule ʻole i kēia hoʻāʻo ʻana a noiʻi ʻia no ka hoʻomaikaʻi ʻana i ke kaʻina hana.
ʻO kēia hoʻāʻo e hōʻoia e hiki i nā paipu ke kūpaʻa i nā pilikia a lākou e hālāwai ai ma ka lawelawe.
5. Nānā Ana a me ka nānā
Loaʻa nā loiloi maikaʻi hope loa:
- Ana o na ana paipu, me ke anawaena, ka manoanoa o ka paia, a me ka loa.
- ʻO ka nānā ʻana i nā hopena paipu a me ka hoʻopau ʻana i ka ʻili.
- Ke nānā nei i ka pololei a me ka poepoe.
Hoʻomaopopo kēia mau nānā ʻana i ka hoʻokō ʻana o nā paipu i nā hoʻomanawanui dimensional i kuhikuhi ʻia a me nā koi o ka ʻili.
E pili ana i ka Pūʻulu Longma
ʻO nā paipu wili wili lōʻihi nā mea nui i nā ʻoihana he nui, e hāʻawi ana i ka ikaika, ka lōʻihi, a me ka versatility. Ma Longma Group, ua kūpaʻa mākou i ka hana ʻana i nā paipu wili wili lōʻihi kiʻekiʻe e kūpono i nā pono like ʻole o kā mākou mea kūʻai aku ma nā ʻāpana like ʻole. ʻO kā mākou mau hana hoʻomalu maikaʻi koʻikoʻi e hōʻoia i kēlā me kēia paipu, inā LSAW, ERW, a i ʻole DSAW, e hoʻokō i nā kūlana kiʻekiʻe o ka hana a me ka hilinaʻi.
Inā ʻoe e ʻimi nei i ka pae kiʻekiʻe paipu wiliwili lōʻihi no kāu papahana, mai hoʻokaʻulua e kelepona mai iā mākou. Mākaukau kā mākou hui loea e kōkua iā ʻoe i ke koho ʻana i ke ʻano paipu kūpono no kāu noi kikoʻī. E kelepona iā mākou ma info@longma-group.com e kūkākūkā i kāu mau koi a ʻike pehea e hiki ai i Longma Group ke kōkua i ka holomua o kāu papahana.
