Hoʻonui i ka Pono Kūʻai: Spiral Welded Carbon Steel Pipe in Metal Pipe Weld Process
Hoʻolauna
ʻO ke akamai owili paipu metalapono i ka hui pū ʻana o ke akamai, ka pololei a me ka maikaʻi o nā mea pono e hōʻoia i ka paʻa o ke kūkulu ʻana no nā noi like ʻole.Ma waena o nā ʻano paipu he nui, ua kaulana ka paipu kalapona i hoʻoheheʻe ʻia, e like me ka paipu X42 SSAW, no kona ikaika kiʻekiʻe, ka lōʻihi a me ke kumukūʻai.Ma kēia moʻomanaʻo, e ʻimi mākou i ke koʻikoʻi o nā paipu hao kalapona i hoʻopili ʻia i loko o ke kaʻina hana kuʻihao metala, e ʻimi ana i kāna kaʻina hana, nā pono a me nā wahi noi.

Kaʻina hana
Ua hana ʻia ka paipu wiliwili spiral, i ʻike ʻia ʻo SSAW (spiral submerged arc welded), me ka hoʻohana ʻana i nā ʻenehana hoʻoheheʻe ʻia a me nā ʻenehana hoʻoheheʻe ʻia.Hoʻomaka ke kaʻina hana me ka hoʻomaʻamaʻa ʻana i ke kaʻe o ke kaula kila i wili ʻia a laila e hoʻopōloli i ke kaula i ke ʻano spiral.Hoʻohana ʻia ka wiliwili arc submerged arc e hui pū i nā ʻaoʻao o nā ʻāpana, e hana ana i kahi wili mau ma ka lōʻihi o ka paipu.ʻO kēia ʻano hana e hōʻoia i ka ikaika a paʻa o ka hui ʻoiai e hōʻemi ana i nā hemahema a me ka mālama pono ʻana i ka hale.
Nā pōmaikaʻi o ka paipu kila carbon welded spiral
1. Ka ikaika a me ka lōʻihi:Paipu kila wiliwili wiliwili ʻiaʻike ʻia ʻo ia no kona ikaika a me ka lōʻihi, kūpono ia no nā noi e koi ana i ke kūpaʻa kiʻekiʻe a me ka hana lōʻihi.
2. Kū'ai-Effectiveness: Hāʻawi kēia mau paipu i kahi hopena maikaʻi ma muli o kā lākou hana hana maikaʻi, hoʻohaʻahaʻa i nā kumukūʻai maka, a hoʻemi ʻia nā koi hana i hoʻohālikelike ʻia me nā ʻano paipu ʻē aʻe.
3. Versatility: ʻO ka versatility o ka spiral welded carbon steel pipe hiki ke hoʻohana ʻia i nā ʻano hana like ʻole, me ka lawe ʻana i ka wai, ka lawe ʻana i ka aila a me ke kinoea, nā hale piling, nā ʻōnaehana wai, a me nā ʻano hana ʻoihana like ʻole.
4. Pono pono: Hiki i ke kaʻina hana spiral ke hoʻomalu pono i ka nui a me ka mānoanoa o ka pā o ka paipu, e hōʻoia i ka pololei a me ka like o ka hana.
Nā wahi noi
1. Aila a me ke kinoea 'oihana: Spiral welded carbon steel pipes ua hoʻohana nui 'ia i loko o ka aila a me ka maoli kinoea 'oihana, oi loa aku ma ka lawe 'ana i ka aila, maoli kinoea a me ka aila huahana.ʻO ko lākou ikaika a me ka hiki ke kū i nā kaiapuni kiʻekiʻe e kūpono iā lākou no nā pipeline lōʻihi.
2. Ka Hoʻouna ʻana i ka wai: Inā no ka hoʻolako ʻana i ka wai kūloko a i ʻole ke kumu irrigation, hāʻawi nā paipu kila carbon welded spiral i kahi hopena maikaʻi loa ma muli o ko lākou pale ʻana i ka corrosion, ikaika a me ka maʻalahi o ke kau ʻana.
3. Kākoʻo kūkulu: Hoʻohana nui ʻia kēia ʻano paipu i ka ʻoihana hana e hāʻawi i ke kākoʻo hoʻolālā no nā hale, nā alahaka, nā pā a me nā papahana ʻē aʻe.ʻO ko lākou lōʻihi a me ke kū'ēʻana i nā mea o waho e hilinaʻi iā lākou i ia mau noi.
4. Nā Hana Hana Hana: Hoʻohana ʻia nā paipu kila carbon welded spiral ma nā ʻano ʻoihana like ʻole e like me ka hana kemika, nā mea kanu mana a me nā hana mining ma muli o ko lākou hiki ke mālama i nā wela kiʻekiʻe, nā kaomi a me nā wahi corrosive.
I ka hopena
ʻO ka paipu hao kalapona wiliwili ʻia, e like meX42 paipu SSAW, ua hoʻololi i ke kaʻina hana wili paipu metala, lawe mai i nā pono he nui i nā ʻoihana like ʻole.ʻO ko lākou ikaika, lōʻihi, kūpono ke kumukūʻai a me ka pololei o ka dimensional e hōʻoiaʻiʻo i ka paʻa o ke kūkulu ʻana i nā ʻano noi.ʻO ka hiki ke kū i nā koʻikoʻi koʻikoʻi, nā mahana a me nā kaiapuni corrosive e kūpono ia no ka lawe ʻana i ka aila a me ke kinoea, ka wai a me nā ʻoihana ʻoihana ʻē aʻe.No laila, i ka wā e pili ana i ka wili paipu metala, ʻo ka hoʻohana ʻana i nā paipu hao kalapona i hoʻopaʻa ʻia i hoʻopaʻa ʻia i mea hilinaʻi a maikaʻi hoʻi e hōʻoiaʻiʻo ai i ka ʻoihana lōʻihi a paʻa.
Hoʻāʻo Hydrostatic
E ho'āʻo ʻia kēlā me kēia lōʻihi o ka paipu e ka mea hana i kahi kaomi hydrostatic e hoʻopuka ai i loko o ka pā paipu i ke koʻikoʻi ʻaʻole i emi iho ma mua o 60% o ka ikaika hua haʻahaʻa i ʻōlelo ʻia ma ka lumi wela.E hoʻoholo ʻia ke kaomi e ka hoohalike penei:
P=2St/D
ʻAe ʻia nā ʻano like ʻole i nā kaumaha a me nā ana
Pono e kaupaona ʻia kēlā me kēia lōʻihi o ka paipu a ʻaʻole e hoʻololi ʻia kona kaumaha ma mua o 10% a i ʻole 5.5% ma lalo o kona kaumaha kumu, i helu ʻia me kona lōʻihi a me kona kaumaha no kēlā me kēia lōʻihi.
ʻAʻole e ʻokoʻa ke anawaena o waho ma mua o ±1% mai ka anawaena waho i koho ʻia
ʻAʻole ʻoi aku ka mānoanoa o ka pā ma kēlā me kēia wahi ma mua o 12.5% ma lalo o ka mānoanoa pā i kuhikuhi ʻia
