ASTM A234 Longitudinal Welded Pipe
Hoʻolauna:
I ka honua o nā paipu kila, hoʻokahi huaʻōlelo maʻamau e piʻi pinepine mai: longitudinally welded pipe.He kuleana koʻikoʻi kēia paipu i nā ʻoihana like ʻole a lawelawe i nā kumu like ʻole.
paipu wiliwili lōʻihi, ʻike ʻia hoʻi ʻo ka paipu wili wili pololei, he paipu kila i hana ʻia me ka pā kila wela a i ʻole ka ʻōwili anu a i ʻole ke kaula hao.ʻO ko lākou inoa mai ke kaʻina hana hoʻoheheʻe, e kū ana ma kahi laina pololei ma ka lōʻihi o ka paipu.Mālama kēia ala i ka maikaʻi o ka weld a me nā hono paʻa, e pale ana i ka leak a me ka hoʻonui ʻana i ka pono o ka hale.

Longitudinal welded paipu:
Ma ka lima ʻē aʻe,paipu wili pololeihana ʻia me ka hoʻohana ʻana i nā ʻenehana welding like ʻole e like me ka arc welding a i ʻole resistance welding.Hana ʻia kēia mau paipu mai nā blank tube seamless a welded, a laila hana ʻia i ke ʻano i makemake ʻia.Hāʻawi ka Longitudinal Welded Pipe i ka ikaika a me ka lōʻihi, e kūpono ia no nā noi ʻoihana e pili ana i nā kūlana kiʻekiʻe a i ʻole nā ukana kaumaha.
Loaʻa nā paipu wili lōʻihi i kahi kaʻina hana kuʻi ʻana e hōʻoia i ka mānoanoa o ka paia o ka paipu me nā hemahema liʻiliʻi.ʻO kēia ka mea i koho maikaʻi loa no nā noi hoʻolālā e like me ke kūkulu ʻana, scaffolding a me ka pilang.
ʻO nā paipu wili pololei, ma kekahi ʻaoʻao, hele mai i nā ʻano like ʻole a me nā nui.ʻO kā lākou hana hana e hiki ai ke hana maʻamau, e kūpono iā lākou no nā noi e koi ana i nā ana kikoʻī a i ʻole nā hoʻolālā paʻakikī.Eia kekahi, hoʻohana nui ʻia nā paipu longitudinally welded i nā ʻoihana e like me ka aila a me ke kinoea, automotive, a me ka aerospace ma muli o ko lākou ikaika kiʻekiʻe a me ke kūpaʻa koʻikoʻi.
ʻIke ʻoihana:
Inā ʻoe e ʻimi nei i nā LSW Pipes hilinaʻi, ʻo Cangzhou Spiral Steel Pipe Group Co., Ltd. he inoa hilinaʻi i ka ʻoihana.Loaʻa i ka hui nā laina hana kūikawā 13 no nā paipu kila spiral, nā laina hana 4 no ka anti-corrosion a me ka mālama wela, a loaʻa iā ia ka ʻenehana loea a me nā mea pono no ka hana ʻana i nā paipu kila kiʻekiʻe.
I ka hopena:
I ka hōʻuluʻulu ʻana, hāʻawi ka paipu welded pololei i nā pōmaikaʻi kūʻokoʻa ma muli o nā koi kikoʻī o kāu papahana a i ʻole noi.Kūlana ʻo Longitudinal Welded Pipe no kona maikaʻi weld mau a me ka paʻa ʻana o ke kūkulu ʻana, ʻoiai ʻo Longitudinal Welded Pipe e hāʻawi i ka versatility i ke ʻano a me ka nui.Ma ka hoʻomaopopo ʻana i kēia mau ʻokoʻa, hiki iā ʻoe ke hoʻoholo i ka ʻike i ke koho ʻana i ka paipu i kūpono i kāu pono.No ka maikaʻi a me ka hilinaʻi, hilinaʻi ʻo Cangzhou Spiral Steel Pipe Group Co., Ltd., he hui i hoʻolaʻa ʻia i ka maikaʻi o ka hana ʻana i ka paipu kila.
