E hooikaika ana i ka wai me na paipu hao kalapona wiliwili

E hooikaika ana i na hana wai me na paipu kalapona huila kii i hoikeia

ʻO ka wehewehe pōkole:

Welina mai iā Cangzhou Spiral Steel Pipe Group Co., Ltd., he mea hana kaulana a me ka mea hoʻolako i nā paipu kila kila kiʻekiʻe.Haʻaheo kā mākou hui i ka hoʻohana ʻana i ka ʻenehana hoʻoheheʻe arc submerged spiral hou e hōʻoiaʻiʻo i ka hana ʻana o nā paipu seam spiral top-notch no nā ʻano noi.

E hoʻouna i ka leka uila iā mākou

Hoʻāʻo Hydrostatic

wehewehe huahana1

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.

1. Ka ikaika o ka paipu kila kalapona i wiliwili ʻia:

Paipu kila wiliwili wiliwili ʻialoaʻa ka ikaika kiʻekiʻe ma muli o kāna hana hana ʻokoʻa.Ma ka hoʻohana ʻana i ka waihona wili wela, hoʻokumu ʻia ka paipu ma o ka weld spiral, ka hopena i ka weld mau.He hana koʻikoʻi kēia i ka mālama ʻana i ka paʻa o ka pipeline, e hōʻoia ana hiki iā ia ke pale i nā koʻikoʻi kiʻekiʻe a me nā kūlana kūlohelohe.ʻO kona ikaika tensile kiʻekiʻe e lilo ia i koho hilinaʻi no ka hoʻolako wai ʻana i ka home a me ka ʻoihana.

2. Ka lōʻihi a me ka corrosion kū'ē:

ʻO kekahi o nā pilikia koʻikoʻi e pili ana i nā papahana hoʻomohala wai ʻo ka ʻino o nā paipu i ka wā.Hōʻike ʻia ka paipu kila kalapona i hoʻopaʻa ʻia i ka palaka maikaʻi loa ma muli o kāna zinc pale a i ʻole ka uhi epoxy.Hana ʻia ka uhi ʻana ma ke ʻano he pale i nā mea o waho, e pale ana i ka ʻōpala a hoʻolōʻihi i ke ola o kāu mau paipu.ʻO kā lākou pale ʻana i ka corrosion e hōʻoia i ka hana lōʻihi i ka wā e hōʻemi ana i nā kumukūʻai mālama paipu wai.

3. ʻAno like ʻole:

He mea maʻalahi ka paipu kalapona i hoʻopaʻa ʻia a kūpono no ka hana ʻoihana wai.Mai ka wai inu wai a hiki i nā mea kanu hoʻomaʻemaʻe wai, hiki ke hoʻololi ʻia kēia mau paipu i nā koi kikoʻī o kēlā me kēia papahana.Hoʻohui ʻia, maʻalahi ka maʻalahi o ka hoʻouka ʻana, ʻoiai ma nā ʻāina paʻakikī a i ʻole nā wahi seismically.

4. Ke kumu kūʻai pono:

Kū pinepine nā papahana hoʻolālā wai i nā kaohi kālā, e hoʻolilo ana i ke kumu kūʻai i mea nui.ʻO ka paipu kalapona i hoʻopaʻa ʻia ʻo Spiral kahi koho paipu waiwai ma muli o kona ola lōʻihi a paʻa.ʻO ko lākou ola lawelawe lōʻihi, i hui pū ʻia me nā koi haʻahaʻa haʻahaʻa, hoʻemi nui i ke kumukūʻai ola o ka papahana.Eia kekahi, ua holomua ka ʻenehana wiliwili kalapona i nā makahiki i hala iho nei, me ka hoʻonui ʻana i ka maikaʻi o ka wiliwili a me ka hoʻemi ʻana i nā kumukūʻai.

5. Nā manaʻo kaiapuni:

ʻO ka hoʻomau ka manaʻo nui i ka hoʻomohala ʻana i nā ʻōnaehana hou.Hoʻokō nā paipu kila kalapona i hoʻopaʻa ʻia me kēia mau loina no ka mea he 100% hiki ke hoʻohana hou ʻia, e kōkua ana i ka hōʻemi ʻana i nā hoʻoiho kalapona i ka wā lōʻihi.Hoʻolaha ko lākou recyclability i ka hoʻokele waiwai circular ʻoiai e hāʻawi ana i kahi hopena hilinaʻi a pili i ke kaiapuni no ka lawe wai.

I ka hopena:

Ua hoʻololi hou ʻo Spiral welded carbon steel pipe i ka ʻāpana ʻoihana wai, hoʻokiʻekiʻe i ka pā no ka hoʻopili ʻana i ka paipu kalapona apaipu laina wai.Hāʻawi kēia mau paipu i ka ikaika ʻoi aku ka maikaʻi, ka lōʻihi, ka pale ʻana i ka corrosion a me ka versatility, e hāʻawi ana i kahi hopena hilinaʻi a maikaʻi hoʻi i nā pono wai ulu o ke kaiāulu.Ma ke koho ʻana i ka paipu kila carbon welded spiral, hiki iā mākou ke hoʻokaʻawale i ke ala no ka wai e hiki mai ana.

Mua: Hoʻomaikaʻi i ka ʻenehana Sewer me ka hoʻohana ʻana i nā Pipes Submerged Arc Pipes (SSAW)

Aʻe: Spiral Submerged Arc Welding In Oil Pipe Line Construction: E hōʻoia ana i ke ola lawelawe a me ka hilinaʻi
