ʻO ka hoʻomaopopo ʻana i ka paipu huila pālua a me ka paipu kila wiliwili spiral ASTM A252

ʻO ka wehewehe pōkole:

Hōʻike kēia ʻāpana o kēia European Standard i nā kūlana hāʻawi ʻenehana no ke anuanu i hoʻokumu ʻia i ka welded structural, nā ʻāpana hollow o nā ʻano circular, square a i ʻole rectangular a pili i nā ʻāpana hollow i hoʻokumu ʻia i ke anuanu me ka ʻole o ka mālama wela.

Hāʻawi ʻo Cangzhou Spiral Steel Pipes Group Co., Ltd i ka ʻāpana hollow o nā ʻano pōʻai i nā paipu kila no ka hale.

Helical Welded Paipu

1. Hoʻomaopopo i ka paipu kila spiral S235 JR:

S235 JR paipu kila kilahe paipu wiliwili spiral i hoʻohana nui ʻia i nā ʻōnaehana pipeline.Hana ʻia lākou me ke kila kiʻekiʻe e like me nā kūlana honua, e hōʻoiaʻiʻo ana i ka lōʻihi a me ka ikaika.ʻO ke kaʻina hana e pili ana i ka hoʻokumu ʻia ʻana o nā ʻāpana kila mau, a laila welded i ka lōʻihi i makemake ʻia.Hāʻawi kēia ʻenehana hana i nā paipu me nā pōmaikaʻi nui ma mua o nā paipu humuhumu pololei.

2. Pono o ka hana paipu wiliwili spiral:

Hāʻawi ka spiral welded construction o S235 JR Spiral Steel Pipe i nā pono he nui i nā ʻōnaehana paipu.ʻO ka mea mua, ʻo ka hoʻomau ʻana o ka spiral weld seams e hoʻomaikaʻi i ka paʻa o ke kūkulu ʻana o ka paipu, me ka pale ʻana i nā kaomi kūloko a me waho.Mālama kēia ʻano hana i ka hāʻawi ʻana i ka ukana, e hōʻemi ana i ka pilikia o ka hāʻule ʻana o ka paipu.Eia kekahi, ʻo ke ʻano spiral o ka paipu e hoʻopau i ka pono no ka hoʻoikaika ʻana i loko, a laila e hoʻomaikaʻi i ka hiki ke kahe a me ka hōʻemi ʻana i nā poho kaomi i ka wā o ka hoʻoili wai.ʻO ka ili mau ʻole o ka paipu spiral e hōʻemi ana i ka hopena o ka leaks a hoʻomaikaʻi i ka palekana a me ka pono o ka ʻōnaehana paipu.

3. Hoʻonui i ka lōʻihi a me ka versatility:

Hāʻawi ka S235 JR Spiral Steel Pipe i ka lōʻihi ma muli o kāna mau mea hana kiʻekiʻe.Kūleʻa lākou i ka corrosion, abrasion a me nā kūlana o ke aniau, e hoʻolilo iā lākou i mea kūpono no nā ʻano noi like ʻole me ka lawe ʻana i ka aila a me ke kinoea, nā ʻōnaehana wai a me nā papahana hoʻolālā.ʻO ka versatility o kēia mau paipu e hiki ke maʻalahi iā lākou e hoʻokō i nā koi o ka papahana.Eia hou, ua maʻalahi lākou e hoʻouka a mālama, hoʻohui hou i kā lākou hoʻopiʻi a kōkua i ka hopena i kahi ʻōnaehana ductwork ʻoi aku ka maikaʻi a me ka manawa.

4. Pono kaiapuni a me ka hoomau ana:

ʻO ka hoʻololi ʻana i ka paipu kila S235 JR i nā ʻōnaehana paipu hiki ke lawe mai i nā pono kaiapuni nui.ʻO ko lākou ola lōʻihi a me ke kūpaʻa ʻana i ka hoʻohaʻahaʻa ʻana e hōʻemi i ka pono no ka hoʻololi pinepine ʻana, e hopena i ka hoʻokuʻu kalapona haʻahaʻa a me ka liʻiliʻi o ka hana ʻōpala.Hoʻohui ʻia, ʻo ka recyclable o ke kila e hana i kēia mau paipu i kahi koho hoʻomau e like me nā loina hoʻokele waiwai.Ma ka hoʻohana ʻana i nā paipu kila spiral S235 JR, hiki i nā ʻoihana ke hōʻoia i kahi ala ʻoi aku ka maikaʻi o ke kaiapuni a me ke kuleana no ka lawe ʻana i nā wai, a laila e hāpai ana i kahi ʻōmaʻomaʻo e hiki mai ana.

Ka hopena:

ʻO ka hoʻohana ʻana o S235 JR spiral steel pipe i nā ʻōnaehana paipu e hāʻawi i kahi ʻano o nā pono koʻikoʻi, me ka hoʻonui ʻana i ka lōʻihi, palekana a me ka pono.ʻO ka spiral welded structure e hōʻoiaʻiʻo i kona kūpaʻa a hāʻawi i ka hāʻawi wai hilinaʻi no nā ʻoihana like ʻole.Ma ka hoʻokomo ʻana i nā ʻenehana holomua e like me kēia, ke wehe nei mākou i ke ala no nā ʻōnaehana paipu paʻa a hilinaʻi.
