Nā Pōmaikaʻi o ka Paipu Laina Kinoea i Hoʻopaʻa ʻia i ka Arc

Wehewehe Pōkole:

Welina mai iā Cangzhou Spiral Steel Pipe Group Co., Ltd., kahi mea hana kaulana a me ka mea hoʻolako i nā paipu kila kalapona wili kiʻekiʻe. Haʻaheo kā mākou hui e hoʻohana i ka ʻenehana wili arc submerged spiral hou e hōʻoiaʻiʻo ana i ka hana ʻana o nā paipu humuhumu spiral kiʻekiʻe loa no nā ʻano hana like ʻole.

E leka uila mai iā mākou

Nā Lepili Huahana

I ke ao o ka plumbing, aia nā ʻano hana kūkulu like ʻole a me nā mea hana. ʻO kahi ʻano hoʻohui paipu kaulana ʻo ka wili ʻākuhi lua-ended submerged (DSAW). Hoʻohana pinepine ʻia kēia ʻano hana ma nā laina kinoea a me ka wai, a no ke kumu maikaʻi. Ma kēia blog e ʻimi mākou i nā pono o ka hoʻohana ʻanahoʻopaʻa ʻia ke arc i hoʻopaʻa ʻia i lalo o ka wai pāluapaipu i loko o kēia mau noi.

Hoʻāʻo Hydrostatic

wehewehe-huahana1

E kū pono ka paipu i ka hoʻāʻo hydrostatic me ka ʻole o ka leakage ma o ka weld seam a i ʻole ke kino paipu
ʻAʻole pono e hoʻāʻo ʻia nā mea hui ma ke ʻano hydrostatic, ke hoʻolako pono ʻia nā ʻāpana o ka paipu i hoʻohana ʻia i ka māka ʻana i nā mea hui ma mua o ka hana hoʻohui.

ʻO ka mea mua, ʻo ka hoʻopili ʻana i nā paipu me ke arc i hoʻopaʻa ʻia i lalo he ala kūpono a hoʻokele waiwai hoʻi ia no ka hoʻohui ʻana i nā paipu. Pili ke kaʻina hana i ka hoʻokumu ʻana i kahi wili ma ke kuʻu ʻana i ka paipu i loko o kahi flux granular me ka hoʻohana ʻana i ʻelua mau arc wili. Hoʻokumu kēia i kahi wili ikaika a paʻa e hiki ke kū i ke kaomi kiʻekiʻe a me ke kaumaha, e kūpono ai no nā laina kinoea a me ka wai.

ʻO kekahi o nā pono nui o ka paipu wili ʻia i hoʻopaʻa ʻia i loko o ka arc pālua ʻo ia kona kūpaʻa i ka pala. ʻO ka flux granular i hoʻohana ʻia i kēia kaʻina hana wili e hana i kahi papa pale ma luna o ka wili, e kōkua ana i ka pale ʻana i ka pala a hoʻolōʻihi i ke ola o ka paipu. He mea nui loa kēia nopaipu laina wai, no ka mea, e hōʻoiaʻiʻo ana e maʻemaʻe mau ana ka wai i hāʻawi ʻia a ʻaʻohe haumia.

Ma waho aʻe o ke kūpaʻa ʻana i ka pala, hāʻawi nā paipu wili ʻākuhi pālua i hoʻopaʻa ʻia i loko o ka wai i nā waiwai mechanical maikaʻi loa. Hoʻopuka kēia ʻano hana i nā wili like a me kahi paipu ikaika a hilinaʻi hoʻi. He mea koʻikoʻi kēia no nā paipu kinoea kūlohelohe no ka mea e hōʻoiaʻiʻo ana i ka halihali palekana a me ka maikaʻi o ke kinoea kūlohelohe me ka ʻole o ka pilikia o ka leaka a i ʻole ka hemahema.

Eia kekahi, hiki i nā paipu i hoʻopaʻa ʻia i loko o ka wai i hoʻopaʻa ʻia i ka arc pālua ke kū i nā mahana koʻikoʻi a me nā kūlana o ke kaiapuni. ʻO kēia ka mea kūpono iā lākou no nā noi ma uka a me waho e hiki ke hoʻopilikia ʻia i ke aniau ʻino a me nā kūlana hana. No nā paipu laina wai, hōʻoia kēia kūpaʻa e hiki i nā paipu ke hoʻoneʻe i ka wai me ka maikaʻi me ka ʻole o ka hoʻopilikia ʻana i ka hana.

ʻO kekahi pono o ka hoʻohana ʻana i ka paipu wili ʻākuhi pālua i hoʻopaʻa ʻia i loko o ka wai, ʻo ia ka laumania a me ka nani o kona ʻili. ʻO kēia ka mea e lilo ai lākou i koho hoihoi no nā hoʻonohonoho ma luna a ma lalo o ka honua, no ka mea, he maʻalahi ke nānā a mālama. Eia kekahi, ʻo ka ʻili laumania o ka wili e hōʻemi ana i ka friction a me ka hāʻule ʻana o ke kaomi i loko o ka paipu, e kōkua ana i ka hoʻomaikaʻi ʻana i ka pono holoʻokoʻa o nā ʻōnaehana hoʻouna kinoea a me ka wai.

I ka hopena, ʻo ka paipu welded arc submerged pālua he koho maikaʻi loa ia nopaipu laina kinoeaa me nā paipu laina wai. ʻO kāna kaʻina hana hoʻoheheʻe kūpono a kūpono hoʻi ke kumukūʻai, me ke kūpaʻa i ka pala, nā waiwai mechanical maikaʻi loa, ka lōʻihi a me nā aesthetics, e lilo ia i koho mua no ke kūkulu ʻana i nā paipu. Inā paha e lawe ana i ke kinoea kūlohelohe a i ʻole ka wai, hāʻawi kēia mau paipu i ka ikaika a me ka hilinaʻi e pono ai e hana palekana a me ka maikaʻi. ʻIke loa, he waiwai nui ka paipu welded arc submerged pālua-papa i ka honua kūkulu paipu.

Ma mua: ʻO ka paipu wili i hoʻoheheʻe ʻia i loko o ka Arc Spiral i loko o nā noi paipu laina API 5L

Aʻe: Nā Pōmaikaʻi o ka hoʻohana ʻana i nā paipu kila Spiral Submerged Arc Welded no nā paipu wai ma lalo o ka honua
