Paipu kila kalapona i hoʻopaʻa ʻia no ke kūʻai aku

Paipu kila kalapona wiliwili no ke kūʻai aku Kiʻi i hōʻike ʻia

Wehewehe Pōkole:

Welina mai iā Cangzhou Spiral Steel Pipe Group Co., Ltd., kahi mea hana kaulana a me ka mea hoʻolako i nā paipu kila kalapona wili kiʻekiʻe. Haʻaheo kā mākou hui e hoʻohana i ka ʻenehana wili arc submerged spiral hou e hōʻoiaʻiʻo ana i ka hana ʻana o nā paipu humuhumu spiral kiʻekiʻe loa no nā ʻano hana like ʻole.

E leka uila mai iā mākou

Nā kikoʻī huahana

Nā Lepili Huahana

ʻO kā mākounā paipu kila kalapona i hoʻopaʻa ʻia me ka wilihana ʻia ma ka ʻōwili ʻana i ke kila kila kalapona haʻahaʻa i loko o kahi paipu hakahaka ma kahi kihi wili kikoʻī, a laila hoʻopili i nā ʻūmi paipu. ʻAe kēia kaʻina hana iā mākou e hana i nā paipu kila anawaena nui, he mea pono loa ia no nā ʻoihana like ʻole. Ma ka hoʻohana ʻana i nā ʻāpana kila haiki, hiki iā mākou ke hana i nā paipu me ka ikaika a me ke kūpaʻa kiʻekiʻe.

Hoʻāʻo Hydrostatic

wehewehe-huahana1

E kū pono ka paipu i ka hoʻāʻo hydrostatic me ka ʻole o ka leakage ma o ka weld seam a i ʻole ke kino paipu
ʻAʻole pono e hoʻāʻo ʻia nā mea hui ma ke ʻano hydrostatic, ke hoʻolako pono ʻia nā ʻāpana o ka paipu i hoʻohana ʻia i ka māka ʻana i nā mea hui ma mua o ka hana hoʻohui.

Me ka nānā nui ʻana i ka maikaʻi, hoʻohana wale mākou i nā mea maikaʻi loa i kā mākou kaʻina hana. ʻO nā mea nui i hoʻohana ʻia i loko o kā mākou mau paipu wiliwili ʻo Q195, Q235A, Q235B, Q345, a pēlā aku. Hōʻoia kēia mau mea kiʻekiʻe e hoʻokō kā mākou mau paipu i nā kūlana ʻoihana i koi ʻia a hiki ke kū i nā kūlana koʻikoʻi.

Ma Cangzhou Spiral Steel Pipe Group Co., Ltd., ke kau nei mākou i ka ʻoluʻolu o ka mea kūʻai aku ma mua a ke hoʻoikaika nei e hāʻawi i nā huahana maikaʻi loa e hoʻokō i kāu mau pono kikoʻī. Loaʻa i ka hui he 13 mau laina hana paipu kila wili a me 4 mau laina hana anti-corrosion a me ka thermal insulation kūikawā. Me kēia mau lako hana holomua, hiki iā mākou ke hana i nā paipu kila wili i hoʻopaʻa ʻia i loko o ka arc me nā diameters mai Φ219 a i Φ3500mm a me nā mānoanoa o ka paia o 6-25.4mm.

Hāʻawi kā mākou mau paipu kila kalapona i hoʻopaʻa ʻia i loko o ka wili i nā pono he nui i nā ʻoihana like ʻole. ʻO ka ikaika a me ke kūpaʻa o kā mākou mau paipu e lilo ai lākou i koho maikaʻi loa no nā papahana ʻoihana e like me ka hoʻolako wai, ka lawe ʻana i ka ʻaila a me ke kinoea, a me ke kūkulu ʻana. Eia kekahi, kūpaʻa kā mākou mau paipu i ka pala, e hōʻoiaʻiʻo ana i ka lōʻihi a me ka hilinaʻi i nā ʻano ʻino.

Eia kekahi, ʻoi aku kā mākou kūpaʻa i ka maikaʻi ma mua o ka hana ʻana. Hoʻokō mākou i nā hana kaohi maikaʻi koʻikoʻi i kēlā me kēia pae e hōʻoia i ka ʻole o nā kīnā o kēlā me kēia paipu kila kalapona i hoʻopaʻa ʻia e haʻalele ana i ka hale hana. Mālama kā mākou hui o nā loea akamai a me ka ʻike i ke kaʻina hana e hōʻoia i ka hoʻokō ʻana o kēlā me kēia huahana a ʻoi aku paha ma mua o nā kūlana o ka ʻoihana.

ʻO ke koho ʻana iā Cangzhou Spiral Steel Pipe Group Co., Ltd. ma ke ʻano he mea hoʻolako hilinaʻi iā ʻoe, ʻo ia hoʻi hiki iā ʻoe ke loaʻa nā paipu kila kalapona wili kiʻekiʻe. Ua kūpaʻa mākou i ka hāʻawi ʻana i nā hopena hilinaʻi a hoʻomau, kahi i hōʻike ʻia ma ka hana lima kiʻekiʻe o kā mākou huahana.

Inā ʻoe e makemake ana i ka paipu kila anawaena nui no kahi papahana kūkulu nui a i ʻole ka paipu e hiki ke kū i nā kūlana koʻikoʻi, ʻo kā mākou paipu kila kalapona wiliwili ka koho kūpono. E kāhea mai iā mākou i kēia lā e ʻike i ka maikaʻi a me ka hilinaʻi o kā mākou huahana. Ua mākaukau mau ʻo Cangzhou Spiral Steel Pipe Group Co., Ltd. e hoʻokō i kāu mau koi a hāʻawi i nā hoʻonā i hana ʻia e ʻoi aku ma mua o kāu mau manaʻolana.

Ka hiki ke hahai ʻia:
No ka paipu PSL 1, pono ka mea hana e hoʻokumu a hahai i nā kaʻina hana i palapala ʻia no ka mālama ʻana:
ʻO ka ʻike wela a hiki i ka wā e hana ʻia ai kēlā me kēia hoʻokolohua kemika pili a hōʻike ʻia ka kūlike me nā koi i kuhikuhi ʻia
ʻO ka ʻike hoʻāʻo-ʻāpana a hiki i ka wā e hana ʻia ai kēlā me kēia hoʻāʻo mīkini pili a hōʻike ʻia ka kūlike me nā koi i kuhikuhi ʻia
No ka paipu PSL 2, pono ka mea hana e hoʻokumu a hahai i nā kaʻina hana i palapala ʻia no ka mālama ʻana i ka ʻike wela a me ka ʻike ʻāpana hoʻāʻo no ia paipu. Pono kēlā mau kaʻina hana e hāʻawi i nā ala no ka hahai ʻana i kekahi lōʻihi o ka paipu i ka ʻāpana hoʻāʻo kūpono a me nā hopena hoʻāʻo kemika e pili ana.
