Kiekie X65 SSAW Line Pipe: He Kiʻekiʻe Kiʻekiʻe No ka Pono a hilinaʻi i ka Pipeline Infrastructure

ʻO ka Pipe Line X65 SSAW kiʻekiʻe: He mea hoʻonā kiʻekiʻe no ka pono a hilinaʻi hoʻi i nā ʻoihana paipu 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.

I ka hoʻonui ʻana o ka ʻoihana a me ka ulu ʻana o ka lehulehu, ʻoi aku ka nui o ka pono o ka lawe ʻana i ka aila, ke kinoea maoli, a me nā mea ʻē aʻe.ʻO ke kūkulu ʻana a me ka mālama ʻana i nā ʻōnaehana pipeline he hana koʻikoʻi i ka hōʻoia ʻana i ke kahe ʻana o nā kumuwaiwai honua.Ma keia manao,X65 SSAW laina paipuua puka mai ma ke ʻano he hopena ʻokiʻoki, e hāʻawi ana i ka maikaʻi kiʻekiʻe a me ka maikaʻi like ʻole i ka hana pipeline.

He aha ka X65 spiral submerged arc welded line pipe?

X65 SSAW (submerged arc welded) laina paipu he ʻano paipu kila i hoʻohana nui ʻia mapaipuhana i loko o ka ʻoihana ʻaila a me ka ʻea.ʻO ka hui pū ʻana o kēia paipu laina o ka ikaika, ka lōʻihi a me ka hana hoʻohiwahiwa i lilo ia i koho mua no nā ʻano papahana a puni ka honua.

Ka ikaika a me ka lōʻihi:

ʻO kekahi o nā hiʻohiʻona nui e hoʻokaʻawale ai i ka X65 spiral submerged arc welded line pipe ʻo ia kona ikaika a me ka lōʻihi.Hana ʻia me ke kila kiʻekiʻe, he kūʻē ikaika i ka paʻi kūloko a me waho.ʻO ia ke koho maikaʻi loa no ke koi ʻana i nā noi aila a me ke kinoea, e hōʻoia i ka hilinaʻi a me ka lōʻihi.

ʻO ka pono hana paipu:

He mea koʻikoʻi ka maikaʻi i ka lawe ʻana i nā kumuwaiwai ma o nā pipeline.ʻOi aku ka maikaʻi o ka paipu laina X65 SSAW ma kēia wahi, e hāʻawi ana i ka holo mālie me ka liʻiliʻi liʻiliʻi, a laila e hōʻemi ana i ka hoʻohana ʻana i ka ikehu i ka wā o ka lawe ʻana.Kōkua kēia hana i ka mālama ʻana i nā kumukūʻai a hōʻemi i ka hopena o ke kaiapuni, e lilo ia i koho ʻoluʻolu.

Kū'ē i nā kaiapuni paʻakikī:

Holo nā ʻupena paipu i nā ʻano kaiapuni like ʻole, me ka ʻino a me ka ʻino.X65 spiral submerged arc welded line pipe ua hōʻoia i kona kūlana kiʻekiʻe ma ia mau kūlana ma muli o kona kūpaʻa maikaʻi loa i ka corrosion, abrasion a me nā mea ʻē aʻe o waho.ʻO kēia kūpaʻa e hōʻoia i ka pono o ka ʻōnaehana paipu, e hōʻemi i nā kumukūʻai mālama, a e hōʻemi i ka hopena o ka leak a i ʻole ka hāʻule.

ASD:

He mea koʻikoʻi ka mālama ʻana i nā hana pipeline palekana.Hoʻokumu ka paipu laina X65 SSAW i ka palekana ma o ka hāʻawi ʻana i nā waiwai mechanical maikaʻi loa a me ka pololei o ke ana.Ma o nā hana hoʻomalu maikaʻi koʻikoʻi, mālama ka pipeline i ka pono o ka hoʻolālā e pono ai ke kū i nā pilikia kiʻekiʻe a me nā kūlana hana paʻakikī, e hōʻoia ana i ka palekana o nā limahana a me nā kumuwaiwai.

I ka hopena:

Kū ka paipu laina X65 SSAW ma ke ʻano he hopena maikaʻi loa i ke kūkulu ʻana a me ka mālama ʻana i nā ʻōnaehana pipeline.ʻO kona ikaika, kūpaʻa, kūpono a me ke kū'ēʻana i nā kaiapuni koʻikoʻi, he koho maikaʻi loa ia no kaʻoihanaʻaila a me ke kinoea a me nāʻoihana'ē aʻe e hilinaʻi ana i ka halihali waiwai kūpono.Hāʻawi ka paipu laina X65 SSAW i ka mālama ʻana i ke kumukūʻai, ka hoʻomau ʻana i ke kaiapuni a me ka hōʻoia palekana, e lilo ia i mea waiwai nui no nā hana pipeline e ʻimi nei e hilinaʻi a maikaʻi.

No laila, inā e hoʻomaka ana ʻoe i kahi papahana paipu, e noʻonoʻo ʻoe i ka paipu laina X65 SSAW he koho maʻalahi e hōʻoiaʻiʻo i ka hana ʻoi aku ka maikaʻi a me ka holomua lōʻihi.E hoʻolilo i kēia hopena kiʻekiʻe a ʻike i ka hopena hoʻololi i hiki ke loaʻa i kāu ʻōnaehana pipeline.

Mua: Paipu kila huila ʻia no ka ikaika like ʻole a me ka maikaʻi ʻo ASTM A252

Aʻe: Nā Paipu wiliwili ʻia ʻo Spiral Seam
