S235 J0 Spiral Steel Pipe – Hana maikaʻi loa o ka Pipe Welded Diameter Nui

S235 J0 Spiral Steel Pipe – Hana maikaʻi loa o ke anawaena welded pipe i hōʻike ʻia

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.

E hoʻouna i ka leka uila iā mākou

Huahana Huahana

Haʻaheo mākou e hoʻolauna i kā mākou huahana top-of-the-line,S235 J0 Paipu kila Spiral, i hoʻolālā ʻia e hoʻokō i nā pono ulu o nā ʻoihana like ʻole.Ma ke ʻano he mea hana alakaʻi ma ke kula, hoʻohana mākou i ka ʻenehana kiʻekiʻe a me ka loea e hana i ka maikaʻi kiʻekiʻepaipu laina me ka lōʻihi a me ka hana.

Hana ʻia kā mākou paipu kila mai loko mai o nā wili kila ma o ke kaʻina hoʻoheheʻe ʻia ʻana o nā uwea pālua ʻelua ʻaoʻao.Ma o ka ʻenehana hoʻoheheʻe ʻana i ka wela mau, hōʻoia mākou e hana ʻia kēlā me kēia paipu me ka pololei kiʻekiʻe a me ke kūlike.ʻO kēia kaʻina hana hana akamai e hōʻoia i ka hoʻokō ʻana o kā mākou huahana i nā kūlana kiʻekiʻe kiʻekiʻe, e kūpono ana iā lākou no nā noi like ʻole.

Hoʻohālikelike ʻia me nā paipu welded kuʻuna,S235 J0 paipu kila kila Loaʻa nā hiʻohiʻona koʻikoʻi penei:

A. I ka wā o ke kaʻina hana, ʻano like ʻole ka pā kila a loaʻa ke koʻikoʻi liʻiliʻi.ʻAʻole wale kēia e hoʻolōʻihi i ke ola o ka paipu, e hōʻoiaʻiʻo nō hoʻi i ka maʻalahi o ka ʻili o ka paipu a me ka ʻole o nā ʻōpala a i ʻole nā hemahema.

b.ʻO kā mākou kaʻina hana hoʻoheheʻe arc submerged ʻaoʻao kiʻekiʻe e hiki ai i ka hoʻopili pololei ʻana i ke kūlana maikaʻi loa.Hoʻemi nui kēia i ka loaʻa ʻana o nā hemahema e like me ke kuhi hewa ʻole, ka hoʻokaʻawale ʻana i ka welding, a me ka hoʻopili piha ʻole.ʻO ka hopena, loaʻa i kā mākou paipu ka maikaʻi wiliwili maikaʻi, maʻalahi ke kāohi a hōʻoia i ka hana maikaʻi loa.

ʻO C. ʻO ka maikaʻi kā mākou mea nui.No laila, hana mākou i ka nānā pono ʻana i ka maikaʻi 100% ma kēlā me kēia paipu kila a mākou e hana ai.Ke hōʻoiaʻiʻo nei kēia nānā piha ʻana i kā mākou paipu i nā kūlana kiʻekiʻe o ka ʻoihana, e hāʻawi iā ʻoe i ka maluhia o ka noʻonoʻo i ka wā o ka hana a me ka hoʻohana ʻana.

Ma Cangzhou Spiral Steel Pipe Group Co., Ltd., haʻaheo loa mākou i ka hana ʻanaS235 J0 Paipu kila Spiral.Aia mākou ma Cangzhou City, Hebei Province a ke lawelawe nei i ka ʻoihana mai ka makahiki 1993. E uhi ana i kahi ʻāpana o 350,000 square square a me nā waiwai a pau o 680 miliona yuan, ua hoʻokumu ʻo ia i kahi kumu paʻa no nā hana hana maikaʻi loa.ʻO kā mākou hui hoʻolaʻa o 680 mau limahana akamai e hana me ka luhi ʻole e hōʻoia i ka hana maʻemaʻe a me ka hāʻawi ʻana i ka manawa kūpono o 400,000 tons o nā paipu kila spiral i kēlā me kēia makahiki.
