Ke hoʻomaʻamaʻa hou ʻia ka noi no nā mea pipeline i ka ʻoihana ʻoihana, ke hoʻomau nei ka kaulana o nā paipu seamless a me nā paipu welded. E kālele ana kēia ʻatikala mai nā hiʻohiʻona o ka haku mele ʻana, nā pōmaikaʻi nui, nā ʻano ʻokoʻa a me nā kahua pili, a hoʻohui i nā huaʻōlelo hulina wela "ke koho ʻana i nā mea pipeline kiʻekiʻe" a me "nā lako hale haʻahaʻa haʻahaʻa" e hāʻawi i ke kuhikuhi no ke kūʻai ʻana i ka ʻenekinia.
1. Mea haku mele
Paipu lauwili ʻole
Nā mea nui: ke kila kalapona kiʻekiʻe (e like me 20 kila, 35 kila), ke kila kila (e like me 16Mn, 40Cr), ke kila kila (304/316L) a me ke kila boiler (20g)
Nā hiʻohiʻona: ʻaʻohe welds, hoʻohui like ʻole, kūpono no ke kiʻekiʻe wela a me nā hiʻohiʻona kiʻekiʻe.
Paipu welo
Nā mea nui: ke kila kalapona haʻahaʻa (Q235), ke kila kila haʻahaʻa (L290, L360), ke kila galvanized a me ke kila kila.
Nā hiʻohiʻona: hana ʻia e ka wili ʻana i nā pā kila, nā kumu kūʻai haʻahaʻa a me nā kikoʻī maʻalahi.
2. Hoʻohālikelike i nā pono kumu
Māhele maikaʻi o ka paipu wili ʻia
ʻO ka ikaika kiʻekiʻe ka ikaika holoʻokoʻa, ʻoi aku ka nui o ka ikaika o ka welding ma mua o 415MPa16, akā hiki ke hoʻokō i nā koi haʻahaʻa haʻahaʻa.
Kaʻina ʻAʻohe welds, pale i ka leakage risk15 ʻO ka hana kiʻekiʻe kiʻekiʻe, 30% -50% haʻahaʻa haʻahaʻa
ʻIke ʻia ka ʻili maʻemaʻe, ʻaʻohe hōʻailona hana3 Loaʻa nā welds, pono ka mālama ʻana i ka ʻili e hoʻomaikaʻi i ka helehelena6
Hoʻohana i ka aila a me ke kinoea kiʻekiʻe, ka mana nuklea, nā mīkini kikoʻī 5 Nā hale kūkulu hale, ʻenekinia kūlanakauhale, ka wai mahiʻai.
3. 4 mau ʻanuʻu e hoʻokaʻawale i nā paipu seamless mai nā paipu welded
E nānā i ka weld: hiki ke ʻike ʻia nā hōʻailona wili laina ma nā paia o loko a me waho o ka paipu i hoʻopaʻa ʻia, a ʻaʻohe seams o ka paipu seamless.
ʻO ka ikaika hoʻāʻo: hiki i nā paipu liʻiliʻi ke kū i nā hoʻokolohua wai kiʻekiʻe (e like me ma luna o 30MPa)
E noʻonoʻo i ka ʻāpana keʻa: ʻokoʻa ka ʻāpana keʻa o ka paipu seamless, a ʻokoʻa iki paha ka mānoanoa o ka paipu welded ma muli o ke kuʻi ʻana.
E nānā i ka palapala hōʻoia: pono e hāʻawi nā paipu ʻole i nā hōʻike ʻike hemahema, a ʻo nā paipu welded e kālele ana i ka hōʻoia maikaʻi ʻana.
4. Manaʻo ʻia nā hiʻohiʻona noi
ʻO nā paipu ʻole:
ʻO ka ʻaila a me ke kinoea maoli: nā paipu hoʻouna kiʻekiʻe (X60/X70 kila kila)
ʻO ka ikehu a me ka mana: nā paipu paila, nā ʻōnaehana hoʻomehana nuklea
ʻO ka hana kiʻekiʻe: nā paipu hydraulic mokulele, nā ʻaukā kaʻa
Paipu huila:
ʻEnekinia hana: ka hale kila, scaffolding
ʻO ke ola o ke kūlanakauhale: ka lako wai a me ka ʻoihana wai, ʻōnaehana HVAC
ʻO ka mahiʻai a me ka ʻoihana: nā paipu wai, nā papa mālama
V. Jindalai Steel: Hoʻokahi hoʻonā paipu
I ka pane ʻana i nā ʻimi hulina hou loa o "ka lako wahi" a me nā "paipu kūʻai kūʻai", ua lilo ʻo Jindalai Steel Company i koho mua o ka ʻoihana me nā mea maikaʻi aʻe:
Nā ʻāpana piha: ka uhi ʻana i ke kila kalapona, ke kila kila, nā paipu wili ʻole a me nā paipu welded, e kākoʻo ana i nā nui maʻamau ʻole.
Pono ke kumu kūʻai: hoʻemi ka hana nui i nā kumukūʻai, a ʻo ke kumukūʻai o nā paipu welded he 10% haʻahaʻa ma mua o ka mākeke.
ʻO ka hōʻoia maikaʻi: hāʻawi i nā hōʻike nānā ʻekolu ʻaoʻao (e like me SGS, BV), i ka laina me GB/T 3091, GB/T 9711 a me nā kūlana aupuni ʻē aʻe.
Pane wikiwiki: 5,000 tons o ka waihona waiwai kū
Ka hopena
ʻO nā paipu liʻiliʻi paha ma lalo o nā hiʻohiʻona kiʻekiʻe a i ʻole nā paipu welded maikaʻi a maikaʻi hoʻi, ke koho ʻana i ka mea kūpono hiki ke hoʻonui i nā pono o ka papahana. ʻO Jindalai Steel, me ka ʻenehana e like me ke kākoʻo a me ka lawelawe ʻana ma ke ʻano he kumu, hāʻawi i nā mea kūʻai aku o ka honua i nā hopena pipeline kūpono e kōkua i nā papahana e pae pono!
(Inā makemake ʻoe i nā ʻāpana kikoʻī a i ʻole nā huaʻōlelo, e ʻoluʻolu e kelepona iā Jindalai Steel Consultant Team no ka loaʻa ʻana o kahi hopena hoʻolaʻa!)
