Paipu laina wiliwili Spiral Seam Steel Paipu

ʻO ka wehewehe pōkole:

Welina mai i ka hoʻolauna huahana spiral seam pipe i lawe ʻia mai iā ʻoe e Cangzhou Spiral Steel Pipe Group Co., Ltd., ka mea hana nui o Kina i nā paipu kila kila a me nā huahana uhi paipu.

Huahana Huahana

Ma Cangzhou Spiral Steel Pipe Group Co., Ltd., kā mākoupaipu hili ʻananā huahana kiʻekiʻe e kū ana i nā kūlana kiʻekiʻe o ka ʻoihana.Hoʻolālā ʻia kā mākou paipu no nā ʻano noi like ʻole a ʻike ʻia no ko lākou kūpaʻa, ikaika a me ka pale ʻana i ka corrosion.

ʻO ke kalapona ka mea nui loa i ke kila a me ke kumu no ka hoʻokaʻawale ʻana i ke kila mai ka hao.Hana ʻia kā mākou mau paipu spiral mai ke kila kalapona kiʻekiʻe e hōʻoia ana i ka ikaika a me ka lōʻihi.Me kā lākou ʻano kalapona kiʻekiʻe, kūpono kā mākou paipu no ka nui o nā noi ʻoihana.

Ma waho aʻe o ke kalapona, loaʻa i kā mākou mau paipu pilipili nā mea koʻikoʻi e like me ka nickel a me ka chromium.ʻO Nickel kahi metala ferromagnetic e hoʻohui i ka ikaika holoʻokoʻa a me ka polishability o ka paipu.Eia kekahi, pale ia i ka corrosion a hōʻoia i ka lōʻihi o ke ola lawelawe no kā mākou paipu.ʻO Chromium, ma ka ʻaoʻao ʻē aʻe, he mea koʻikoʻi i loko o ke kila kila a ʻoi aku ka maikaʻi o ka pale ʻana i ka corrosion.ʻO ka hoʻokomo ʻia ʻana o ka chromium i loko o kā mākou paipu seam spiral e hoʻonui i ko lākou lōʻihi a me ka hilinaʻi.

ʻO kekahi o nā mea maikaʻi nui o kā mākou mau paipu wiliwili spiral ʻo kā lākou hoʻolālā seamless, i hoʻokō ʻia ma o ka ʻenehana welding kiʻekiʻe.ʻO kā mākouʻenehanaʻenehana SAWH (Submerged Arc Spiral Welding) e hoʻopaʻa i kahi paʻa ikaika a lōʻihi ma waena o nā paipu kila.ʻO kēia ʻenehana welding ʻaʻole e hoʻonui wale i nā waiwai mechanical o ka paipu, akā e hōʻoiaʻiʻo nō hoʻi i ka ʻili o loko maʻemaʻe, kahi e kūpono ai i ke kahe maikaʻi o nā ʻano wai a me nā kinoea.

Hoʻohana nui ʻia kā mākou paipu spiral seam i nā ʻoihana he nui, me ka aila a me ke kinoea, ka lawe ʻana i ka wai, ke kūkulu ʻana a me ka hoʻomohala ʻana i nā ʻoihana.Hiki ke hoʻokō ʻia ma nā papahana uka a me waho a ma nā ʻōnaehana pipeline no nā kumu like ʻole.Me kona pale ʻana i ka corrosion maikaʻi loa a me ka ikaika tensile kiʻekiʻe, ʻo kā mākou paipu ke koho mua loa no ka wili paipu i nā wahi paʻakikī.

a.Ua koho ʻia ke ʻano deoxidation penei:

FF: Ke kila make loa i loaʻa nā mea hoʻopaʻa naikokene i nā nui e hiki ai ke hoʻopaʻa i ka nitrogen i loaʻa (e laʻa me min. 0,020 % ka huina Al a i ʻole 0,015 % soluble Al).

b.ʻAʻole pili ka waiwai kiʻekiʻe no ka nitrogen inā hōʻike ka haku mele ʻana i ka liʻiliʻi loa o ka maʻiʻo Al o 0,020 % me ka palena liʻiliʻi o Al/N o 2:1, a i ʻole inā lawa nā mea hoʻopaʻa paʻa N ʻē aʻe.E hoʻopaʻa ʻia nā mea hoʻopaʻa N i loko o ka Palapala Nānā.

Ma Cangzhou Spiral Steel Pipe Group Co., Ltd., kau mua mākou i ka maikaʻi a me ka ʻoluʻolu o ka mea kūʻai aku.ʻO kā mākou hui hoʻolaʻa o ka poʻe loea e hōʻoia i kēlā me kēia paipu spiral seam e hoʻokō i nā kaʻina hoʻokele maikaʻi e kū i nā kūlana honua.Eia kekahi, ke hāʻawi nei mākou i kahi ākea o nā koho uhi no nā paipu, me ka epoxy, polyethylene a me ka mortar cement, e hoʻonui hou i ka pale ʻana o ka paipu a hoʻonui i kona ola lawelawe.

Ma ka hōʻuluʻulu

Haʻaheo ʻo Cangzhou Spiral Steel Pipe Group Co., Ltd. i ka hāʻawi ʻana i nā paipu seam spiral kiʻekiʻe no nā ʻano noi like ʻole.Kūleʻa mākou i ka hana pololei, ʻenehana welding kiʻekiʻe a me nā mea maikaʻi e hāʻawi i nā mea kūʻai aku i nā hopena hilinaʻi a maikaʻi hoʻi no kā lākou pono paipu.E hilinaʻi iā mākou e hoʻokō i kāu mau koi āpau a ʻike mua i ka hilinaʻi a me ke kūpaʻa ʻana o kā mākou paipu humuhumu spiral.
