API 5L he maʻamau i ʻike nui ʻia e hōʻike ana i nā koi mua no nā kaila laina i hoʻohana ʻia i ka lawe ʻana i ka wai, gas, a me ka aila. Hoʻopili ka maʻamau i nā ʻano kila like ʻole a me nā ʻano welding e hōʻoiaʻiʻo ana i nā kahawai hiki ke kū i nā paona a me nā kūlana e kau ʻia ai lākou. ʻO ka welding kahi hiʻohiʻona kumu o ka hana ʻana i ka paipu, ʻoiai ʻo ia ka mea e hoʻoholo ai i ke akamai kumu a me ke ola o ka paipu.
API 5L paipu wili Hiki ke hana ʻia me ka hoʻohana ʻana i nā ʻano welding like ʻole, ma muli o nā ʻāpana e like me ka mamao o ka paipu ma waena, ka mānoanoa divider, loiloi lole, a me nā koi hoʻonui.
Hoʻoheheʻe ʻia Bend Submerged (SAW): ʻO ka hoʻoheheʻe ʻana i loko o ka wai he mea hoʻohua nui ka hoʻomākaukau ʻana kūpono no ka wili ʻana i nā paipu pā mānoanoa. I loko o kēia lima, hoʻokomo ʻia kahi piko ma lalo o kahi papa flux granular, kahi e hōʻoia ai i ka weld mai ka hoʻohaumia barometrical. Hoʻohana mau ʻia ʻo SAW no ka wiliwili lōʻihi a me ka wiliwili ʻana o nā paipu nui-diameter.
Kuʻi Kuʻi Uila (RW): ʻO ke kuʻi ʻana i ka uila he lima wiliwili maʻalahi i hoʻohana mau ʻia no ka hana ʻana i nā paipu liʻiliʻi a hiki i ke anawaena waena. I ka welding ERW, ua hoʻomehana ʻia nā ʻaoʻao paipu a hui pū ʻia me ka hoʻohana ʻana i ka pale uila a me ke kaumaha. He kūpono ʻo ERW no ka wiliwili lōʻihi a me ka helical crease.
Kuʻi ʻana i ke kinoea metala Bend (GMAW): ʻO ka hoʻoheheʻe ʻia ʻana o ke kinoea metala pōʻai, ʻoi aku ka ʻike ʻia ʻo MIG (metal idle gas) welding, hoʻohana i kahi uea hoʻopau hoʻopau a me ka pale kinoea e hana i ka weld. He kūpono ʻo GMAW no ka wiliwili ʻana i nā paipu ʻoi aku ka lahilahi a hiki ke hoʻohana ʻia no nā kaʻina hana wili lima a me robotized.
ʻO ke kinoea ʻo Tungsten Bend Welding (GTAW): ʻO ka hoʻoheheʻe ʻia ʻana o ke kinoea tungsten circular segment, ʻoi aku ka ʻike ʻia ʻo TIG (tungsten dormant gas) welding, hoʻohana i kahi pahu tungsten non-consumable a me nā kinoea pale ʻole e hana i ka weld. Hoʻopuka ʻo GTAW i nā welds kiʻekiʻe me ka mana pololei ma luna o ka hoʻokomo mehana a kūpono no ka wiliwili ʻana i nā paipu pā lahilahi a me ke aʻa i loko o nā paipu pā mānoanoa.
Kuʻi uila: ʻO ka wili uila he hana kuʻihao kūikawā i hoʻohana ʻia no ka hoʻopili ʻana i nā pani paipu i ka hana o nā paipu API 5L. I ka wili kuʻi ʻana, hoʻomaʻamaʻa ʻia ka pani ʻana o ka paipu e ke kūpaʻa uila a ma ia manawa i hana pū ʻia ma lalo o ke kaumaha, e hana ana i kahi hui welded mau.
ʻO ke koho ʻana o ke ʻano hoʻoheheʻe no nā paipu welded API 5L e pili ana i nā ʻāpana e like me ka hoʻoholo ʻana o ka paipu, ka mākaukau o ka hana, nā pono o ka weld, a me nā noʻonoʻo ʻana. E koho maʻamau nā mea hana i ka hoʻomākaukau kuʻi ʻana kūpono loa e pili ana i kēia mau ʻano e hōʻoiaʻiʻo i ka hoʻoholo a me ka hoʻokō ʻana i nā paipu welded.
ʻO ka nānā ʻana i nā kaʻina hana hoʻoheheʻe ma API 5L Pipes
Hana ʻia nā paipu API 5L me ka hoʻohana ʻana i nā kaʻina hana welding, kēlā me kēia me kāna mau pono ponoʻī a me nā noi kūpono. ʻO ke kaʻina hana hoʻoheheʻe e hoʻoikaika nui i nā waiwai mechanical o ka paipu a me ke kū'ēʻana i nā mea kaiapuni. ʻO nā ʻano hana wili mua i uhi ʻia e ka API 5L maʻamau e komo pū me ka Electric Resistance Welding (ERW), Longitudinal Submerged Arc Welding (LSAW), Double Submerged Arc Welding (DSAW), a me Spiral Submerged Arc Welding (SSAW).
ERW (Electric Resistance Welded) Paipu
ERW He ala kaulana ia no ka hana ʻana i nā paipu me ke anawaena a hiki i 16 iniha. ʻO ke kaʻina hana ka hoʻohana ʻana i ka wela i hana ʻia e ke au uila kiʻekiʻe e hoʻohui i nā kihi o ka metala. ʻIke ʻia nā paipu ERW no ko lākou kumukūʻai kūpono a me nā wikiwiki hana kiʻekiʻe. He kūpono lākou no nā noi haʻahaʻa haʻahaʻa a hoʻohana nui ʻia i ka wai, ke kinoea, a me ka lawe ʻana i ka aila.
LSAW (Longitudinal Submerged Arc Welded) Paipu
LSAW hana ʻia nā paipu ma ke kuʻi ʻana i ke kila lōʻihi a hoʻomau ʻia i hana ʻia i ke ʻano cylindrical. Hana ʻia ke kuʻi ʻana me ka hoʻohana ʻana i kahi kaʻina arc submerged, e hāʻawi ana i kahi weld komo hohonu me ka liʻiliʻi o ka wela wela. Hōʻike ʻia nā paipu LSAW e ko lākou maikaʻi weld kiʻekiʻe a kūpono i nā noi kiʻekiʻe a me nā wahi paʻakikī.
DSAW (Double Submerged Arc Welded) Paipu
DSAW he kaʻina hana kuʻikuʻi kūikawā e pili ana i ʻelua wili arc submerged arc, hoʻokahi ma loko a hoʻokahi ma waho o ka paipu. Hoʻohana ʻia kēia ʻano hana no ka hana ʻana i nā paipu me kahi kiʻekiʻe o ka pololei a me ka maikaʻi, e hoʻolilo iā lākou i mea kūpono no nā noi koʻikoʻi kahi i hilinaʻi nui ʻia. Hāʻawi nā paipu DSAW i nā waiwai mechanical i hoʻonui ʻia a hoʻohana pinepine ʻia i ke kūkulu ʻana i nā pipeline e lawe ana i nā wai corrosive a i ʻole ka wela wela.
SSAW (Spiral Submerged Arc Welded) Paipu
SSAW hana ʻia nā paipu ma ka hana ʻana i kahi kaula kila a lilo i ʻōwili a hoʻopaʻa ʻia nā ʻaoʻao me ka hoʻohana ʻana i ke kaʻina arc i lalo. Hiki i ka spiral formation ke hana i nā paipu me ke anawaena nui aʻe a me ka mānoanoa o ka paia ma mua o nā ʻano hana ʻē aʻe. ʻIke ʻia nā paipu SSAW no ko lākou kūlike a me ke kūʻē ʻana i ka corrosion, e hana ana iā lākou i koho maikaʻi loa no nā papahana pipeline lōʻihi.
API 5L Mea Hoʻolako Paipu Welded
Hui Longma He mea hoʻolako kaulana ʻo API 5L welded pipes, e hāʻawi ana i kahi ākea o nā māka kila mai B a i X80 a me nā ʻano wili me ERW, LSAW, DSAW, a me SSAW. Me ka hoʻokō i ka maikaʻi a me ka pili ʻana i nā kūlana ʻoihana, ua hōʻoia ʻo Longma Group e hoʻokō kā lākou paipu i nā pono like ʻole o nā mea kūʻai aku ma nā ʻāpana like ʻole. No ka poʻe e ʻimi nei i nā mea hana paipu welded API 5l pono, ua kono ʻo Longma Group i nā nīnau info@longma-group.com.
ʻO ke kūlana hāʻawi kikoʻī o nā paipu welded API 5L pono e kuhikuhi ʻia e ka mea kūʻai aku e pili ana i kā lākou noi noi a me nā mana hana o ka mea hana. Hoʻohui ʻia, hiki ke kuhikuhi ʻia nā koi hoʻohui e like me ka hoʻāʻo ʻana i ka hopena, ka hoʻāʻo non-destructive, a me nā palena hoʻohui kemika ma muli o nā kūlana lawelawe i manaʻo ʻia.
He mea koʻikoʻi ke koho ʻana i ke ʻano wili kūpono no nā paipu API 5L no ka hōʻoia ʻana i ka palekana, hilinaʻi, a me ka lōʻihi o nā paipu. Loaʻa i kēlā me kēia kaʻina hoʻoheheʻe ʻana i kona mau hiʻohiʻona kūʻokoʻa, kūpono ia no nā noi kikoʻī. ʻO ka hoʻomaopopo ʻana i kēia mau ʻokoʻa ke kī nui i ka hoʻokō ʻana i ka hana pipeline a me ke koho ʻana i ka mea hoʻolako kūpono, e like me Longma Group, e hāʻawi ana i nā ʻano koho e hoʻokō i nā koi o ka papahana.
