ʻO ka paipu hao hao ʻāwili ʻia no ke kūʻai ʻana
ʻO kā mākoupaipu kila wiliwili ʻiahana ʻia ma ka ʻōwili ʻana i ke kila kalapona kalapona haʻahaʻa i loko o kahi paipu hakahaka ma kahi kihi spiral kikoʻī, a laila hoʻopaʻa ʻia nā hili paipu.ʻO kēia kaʻina hana e hiki ai iā mākou ke hana i nā paipu kila nui ke anawaena, he mea maikaʻi loa ia i 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 ka lōʻihi.

Hoʻāʻo Hydrostatic
E kū ka paipu i ka hoʻāʻo hydrostatic me ka ʻole o ka leaka ma o ka weld seam a i ʻole ke kino paipu
ʻAʻole pono e hoʻāʻo hydrostatically nā hui hui, inā ua hoʻāʻo maikaʻi ʻia nā ʻāpana o ka paipu i hoʻohana ʻia no ka hōʻailona ʻana i nā mea hoʻohui i ka hydrostatically ma mua o ka hana ʻana.
Me ka manaʻo nui i ka maikaʻi, hoʻohana wale mākou i nā mea maikaʻi loa i kā mākou hana hana.ʻO nā mea nui i hoʻohanaʻia i loko o kā mākou mau paipu spiral welded he Q195, Q235A, Q235B, Q345, a me nā mea'ē aʻe.
Ma Cangzhou Spiral Steel Pipe Group Co., Ltd., kau mākou i ka ʻoluʻolu o ka mea kūʻai aku ma mua a hoʻāʻo e hāʻawi i nā huahana maikaʻi loa e kūpono i kāu mau pono kikoʻī.Loaʻa i ka hui nā laina 13 spiral steel pipe production a me 4 kūikawā anti-corrosion a me nā laina hana insulation thermal.Me kēia mau mea hana kiʻekiʻe, hiki iā mākou ke hana i nā paipu kila spiral submerged arc welded spiral me nā anawaena mai Φ219 a i Φ3500mm a me ka mānoanoa o ka paia o 6-25.4mm.
Hāʻawi kā mākou mau paipu kila carbon welded spiral i nā pono he nui i nā ʻoihana like ʻole.ʻO ka ikaika a me ka lōʻihi o kā mākou paipu e lilo ia i mea koho maikaʻi loa no nā hana ʻoihana e like me ka lako wai, ka aila a me ka lawe ʻana i ke kinoea, a me ke kūkulu ʻana.Eia kekahi, ʻo kā mākou mau paipu he corrosion-resistant, e hōʻoiaʻiʻo ana i ka lōʻihi a me ka hilinaʻi i nā wahi paʻakikī.
Eia kekahi, ʻoi aku kā mākou kūpaʻa i ka maikaʻi ma mua o ka hana.Hoʻokō mākou i nā hana hoʻomalu maikaʻi i kēlā me kēia pae e hōʻoia i kēlā me kēia paipu kila kalapona i wiliwili ʻia e haʻalele ana i ka hale hana ʻaʻohe kīnā.ʻO kā mākou hui o nā poʻe akamai loa a ʻike i ke kaʻina hana e hōʻoia i kēlā me kēia huahana e hoʻokō a ʻoi aku paha i nā kūlana ʻoihana.
ʻO ke koho ʻana iā Cangzhou Spiral Steel Pipe Group Co., Ltd. ma ke ʻano he mea hoʻolako hilinaʻi ʻo ia ka mea hiki iā ʻoe ke kiʻi i nā paipu kila welded kiʻekiʻe.Hoʻopaʻa mākou i ka hāʻawi ʻana i nā hopena hilinaʻi a hoʻomau, i ʻike ʻia i ka hana ʻoi aku o kā mākou huahana.
Inā makemake ʻoe i ka paipu kila ke anawaena nui no kahi papahana hana nui a i ʻole ka paipu e hiki ke kū i nā kūlana koʻikoʻi, ʻo kā mākou spiral welded carbon steel pipe ka koho maikaʻi loa.E kelepona iā mākou i kēia lā e ʻike i ka maikaʻi ʻole a me ka hilinaʻi o kā mākou huahana.Mākaukau mau ʻo Cangzhou Spiral Steel Pipe Group Co., Ltd. e hoʻokō i kāu mau koi a hāʻawi i nā hopena maʻamau i ʻoi aku ma mua o kāu mau manaʻo.
Hiki ke huli:
No ka paipu PSL 1, e hoʻokumu ka mea hana a hahai i nā kaʻina hana i kākau ʻia no ka mālama ʻana:
Hōʻike ʻia ka ʻike wela a hiki i kēlā me kēia hoʻokolohua chmical pili a hōʻike ʻia ka conformance me nā koi i kuhikuhi ʻia
Hōʻike ʻia ka ʻike hoʻāʻo a hiki i kēlā me kēia hoʻokolohua mechanical pili a hōʻike ʻia ke kūlike me nā koi i kuhikuhi ʻia
No ka paipu PSL 2, e hoʻokumu a hahai ka mea hana i nā kaʻina hana i kākau ʻia no ka mālama ʻana i ka ʻike wela a me ka ʻike hoʻāʻo no ia paipu.E hāʻawi ia mau kaʻina hana i nā ala no ka ʻimi ʻana i ka lōʻihi o ka paipu i ka ʻāpana hoʻāʻo kūpono a me nā hopena hoʻokolohua pili.
