SAWL paipu kilahe paipu kila wiliwili lōʻihi i hana ʻia me ke kaʻina hana Submerged Arc Welding (SAW).
SAWL= LSAW
ʻElua mau inoa ʻokoʻa no ka ʻenehana hoʻoheheʻe hoʻokahi e pili ana i nā paipu kila arc-welded longitudinally submerged.ʻO kēia nomenclature ka hopena o nā kuʻina ʻōlelo a me nā ʻokoʻa kūloko, akā ʻo ka mea nui, wehewehe ʻelua i ka hana hana like.
Nā ʻano hana hana SAWL
Ke koho ʻana a me ka hoʻomākaukau ʻana o ka pā → ʻoki ʻana a me ka ʻoki ʻana i ka wili → ka hoʻomaʻamaʻa ʻana a me ka hoʻoheheʻe mua ʻana → ka hoʻoheheʻe ʻana i loko a me waho → ka nānā ʻana o ke kuʻi ʻana o ka welding → ka hoʻopololei, ka hoʻonui ʻana a me ka ʻoki ʻana i ka lōʻihi → ka mālama wela → ka mālama ʻana a me ka pale ʻana → ka nānā hope a me ka hoʻopaʻa ʻana.
Ke koho a me ka hoʻomākaukau ʻana i ka pā
Ke koho ʻana i nā mea pā kila kūpono, ʻo ka maʻamau ka ikaika kiʻekiʻe ke kila kalapona a i ʻole ka pā kila.
Pono e hoʻomaʻamaʻa ʻia ka pā kila e wehe i ka ʻōpala, ka ʻaila, a me nā mea haumia ʻē aʻe ma mua o ka hana ʻana.
ʻOki a me ka Milling Edge
ʻOki ʻana i nā pā kila: ʻO ka ʻoki ʻana i nā pā kila i ka nui kūpono e like me ke anawaena o ka paipu kila e hana ʻia.
Miling lihi: hoʻohana ʻana i ka mīkini wili lihi, e wehe ana i nā burrs a me ke ʻano o ka lihi kūpono.
Hoʻokumu
Hoʻopili ʻia kahi pā kila pālahalaha ma o ka wili wili i mea e hana mālie ʻia i loko o kahi ʻano cylindrical hāmama.ʻO ke kaʻina hana maʻamau ʻo JCOE.
ʻO ke kuʻi ʻana a me ka wili mua
Hoʻohana ʻia ka mea hoʻohana i ka seamer pre-weld, seam, a me ka pre-weld i hana ʻia.
Ma mua o ka wili ʻana i nā wēlau o nā papa e hoʻoponopono i ke ʻano a hōʻoia i ka hoʻohui pono ʻana o nā paipu i ka wā o ke kaʻina hana wili.
Kuʻo Kuʻo Kulo a me waho
Hoʻopili ʻia nā ʻaoʻao lōʻihi (longitudinal seams) o ka paipu me ka hoʻohana ʻana i ka ʻenehana hoʻoheheʻe arc submerged.Hana ʻia kēia ʻanuʻu i ka manawa like i loko a i waho o ka paipu.
Hoʻokomo ʻia ka weld arc submerged i loko o kahi wahi i hoʻopaʻa ʻia a i ʻole semi-enclosed kahi i uhi ʻia ka wahi weld me ka nui o ka flux e pale ai i ka oxidation a mālama i ka weld maʻemaʻe.
Nānā hili ʻana
Ma hope o ka hoʻopau ʻana i ka weld, nānā ʻia ka weld me ka nānā ʻole ʻia (e laʻa me ka X-ray a i ʻole ka hoʻāʻo ultrasonic) e hōʻoia i ka ʻole o ka weld i nā hemahema a kū i nā kūlana maikaʻi.
Hoʻopololei, Hoʻonui Anu a ʻokiʻoki i ka lōʻihi
Me ka mīkini hoʻopololei, e hoʻopololei i ka paipu kila.E hōʻoia i ka pololei o ka paipu kila i nā koi maʻamau
E hoʻonui i ka paipu kila ma o ka mīkini hoʻonui anawaena e hoʻokō i ke anawaena kūpono a hoʻopau i ke koʻikoʻi.
Eʻoki i ka paipu kila i nā lōʻihi i'ōleloʻia e like me nā koi o ka mea kūʻai.
Hoʻomaʻamaʻa Wela
Inā makemake ʻia, mālama ʻia nā paipu i ka wela, e like me ka normalized a i ʻole annealed, e hoʻoponopono i nā ʻano mechanical o nā paipu a hoʻonui i ka paʻakikī a me ka ikaika.
Lapaʻau ʻili a me ka pale ʻana
Hoʻopili ʻia nā lāʻau lapaʻau, e like me ka anti-corrosion coatings, i ka ʻili o nā paipu kila e hoʻomaikaʻi i ko lākou kūpaʻa corrosion a me ke ola lawelawe.
ʻO ka nānā hope a me ka hoʻopili ʻana
Ma hope o ka pau ʻana o nā ʻanuʻu hana a pau, hana ʻia ka nānā ʻana i ka nui a me ka maikaʻi e hōʻoia i ka hoʻokō ʻana o ka huahana i nā kikoʻī.Hana ʻia ka ʻeke kūpono i ka hoʻomākaukau ʻana no ka hoʻouna ʻana.

Mīkini ʻoki pā hao, mīkini wili pā kila, mīkini paʻi mua, ʻo ka mīkini hoʻoheheʻe ʻia, ka mīkini hana paipu kila, ka paipu kila ma mua o ka welding seam machine, ka mīkini wili kūloko, ka mīkini kuʻekuʻe waho, ka mīkini hoʻopololei hoʻopau, ka mīkini hoʻopololei, ke poʻo palahalaha chamfering mīkini, mīkini hoʻonui.
Na Mea Nui o SAWL
ʻO ka hao hao
ʻO ka mea maʻamau no ka nui o nā noi maʻamau.ʻOkoʻa ke kila kalapona e like me kona ʻano kalapona a me nā mea hoʻohui ʻē aʻe i hoʻohui ʻia e hoʻoponopono i kona ikaika, paʻakikī, a me ka pale ʻana i ka corrosion.
Ke kila haʻahaʻa haʻahaʻa
Hoʻohui ʻia nā mea hoʻohui liʻiliʻi (e laʻa, nickel, chromium, molybdenum) i mea e hoʻomaikaʻi ai i nā waiwai kikoʻī, e like me ka maikaʻi o ka haʻahaʻa haʻahaʻa a i ʻole ke kūpaʻa ʻana.
ʻO nā hao hao haʻahaʻa haʻahaʻa ikaika kiʻekiʻe (HSLA):
Hāʻawi nā haku mele haʻahaʻa haʻahaʻa i hoʻonui ʻia i ka ikaika a me ka paʻakikī ʻoiai e mālama ana i ka weldability maikaʻi a me ke ʻano.
Kila kohu ʻole
Hoʻohana ʻia i nā wahi ʻino loa e like me ka subsea a i ʻole nā mea hana kemika.Hāʻawi ka paipu kila kila i ka corrosion maikaʻi loa a me ke kūpaʻa wela kiʻekiʻe.

Nā hiʻohiʻona hana o SAWL Steel Pipe
ʻO ka ikaika mechanical kiʻekiʻe a me ka paʻakikī
hiki ke pale aku i ke kaomi kiʻekiʻe a me nā kaiapuni paʻakikī, kūpono no nā noi e koi ana i ka ikaika kiʻekiʻe.
ʻOi aku ka pololei o ke ana
ʻO ke kaʻina hana kūpono e hōʻoia i ka kūlike o ke anawaena a me ka mānoanoa o ka paia, e hoʻomaikaʻi i ka hilinaʻi holoʻokoʻa o ka ʻōnaehana paipu.
ʻO ka maikaʻi wiliwili maikaʻi
Hoʻemi ʻia ka welding arc submerged i ka oxidization ma lalo o ka hopena o ka pale kinoea a me ka flux, e hoʻonui ai i ka maʻemaʻe a me ka ikaika o ka weld.
Kūleʻa kino kiʻekiʻe
ʻO ka hoʻomaʻamaʻa anti-corrosion ʻē aʻe e kūpono ia no nā ʻano ākea ākea, me ka submarine a i ʻole nā pipeline lalo.
He kūpono no ka halihali lōʻihi
ʻO ka ikaika kiʻekiʻe a me ke kūpaʻa dimensional e kūpono ia no ka lōʻihi o ka ʻaila a me nā paipu kinoea.
Noi no ka paipu kila SAWL
Hiki ke hōʻuluʻulu ʻia nā noi nui loa o ka paipu kila SAWL e like me ka lawe ʻana i ka medium a me ka hoʻohana ʻana.
Ka hoʻolaha ʻana i ka media
He kūpono loa nā paipu kila SAWL no ka lawe ʻana i nā media e like me ka aila, ke kinoea, a me ka wai.Ma muli o ko lākou mau ʻano mechanical kiʻekiʻe a me ke kūpaʻa kiʻekiʻe, hoʻohana mau ʻia kēia mau paipu i ka lōʻihi o lalo a i ʻole ka ʻaila submarine a me nā pipeline lawe ʻana i ke kinoea, a me nā lako wai a me nā ʻōnaehana wai.
Hoʻohana hale
Hāʻawi ka paipu kila SAWL i ka ikaika a me ke kūpaʻa e pono ai i ke kūkulu ʻana i nā alahaka, nā hale kākoʻo kūkulu hale, nā paepae waho, a me nā hale ʻē aʻe e pono ai ka ikaika kiʻekiʻe a me ka lōʻihi.Hoʻohana kēia mau noi i ka hiki ke lawe haʻahaʻa kiʻekiʻe a me nā waiwai wili maikaʻi o ka paipu kila.
ʻO kā mākou huahana pili
Ma keʻano he mea hana paipu kila kila a me ka mea kūʻai nui ma Kina, ua paʻa mākou i ka hāʻawiʻana i kā mākou mea kūʻai i nā huahana kiʻekiʻe a me ka lawelawe maikaʻi loa.Inā makemake ʻoe i ka paipu kila a i ʻole nā huahana pili, e ʻoluʻolu e kelepona mai iā mākou.Ke kakali nei mākou i ka loaʻa ʻana o kāu nīnau a hāʻawi iā ʻoe i nā hāʻina ʻoluʻolu.
