Nā Pōmaikaʻi o Welded Cold Formed Welded Structural Pipes

Ma nā ʻāpana hana a me nā hana hana, ʻo ke koho ʻana i nā mea welding a me nā ʻano hana he mea koʻikoʻi i ka hoʻokō kūleʻa ʻana o kekahi papahana.ʻO kekahi mea i kaulana i nā makahiki i hala iho nei, ʻo ia ka paipu welded welded structural pipe.Hāʻawi kēia huahana hou i nā mea maikaʻi ma mua o nā paipu kuʻuna ʻole a welded paha, ʻoi aku ka nui o nā paipu seam spiral.

 Anuanu hana welded structuralhana ʻia ka paipu ma o ke kaʻina hana anu, ʻo ia hoʻi ke kulou a me ka hana ʻana i nā wili kila i ke ʻano i makemake ʻia.ʻO ka hopena he paipu ikaika a paʻa, akā māmā a maʻalahi hoʻi e hoʻohana.Hoʻohui, ʻo ke kaʻina hana anuanu e hōʻoia i ka mālama ʻana o ka paipu i kona kūpaʻa a me ka pololei o ka dimensional, e kūpono ia no nā noi wili.

Hoʻāʻo Hydrostatic

E ho'āʻo ʻia kēlā me kēia lōʻihi o ka paipu e ka mea hana i kahi kaomi hydrostatic e hoʻopuka ai i loko o ka pā paipu i ke koʻikoʻi ʻaʻole i emi iho ma mua o 60% o ka ikaika hua haʻahaʻa i ʻōlelo ʻia ma ka lumi wela.E hoʻoholo ʻia ke kaomi e ka hoohalike penei:
P=2St/D

ʻAe ʻia nā ʻano like ʻole i nā kaumaha a me nā ana

Pono e kaupaona ʻia kēlā me kēia lōʻihi o ka paipu a ʻaʻole e ʻokoʻa kona kaumaha ma mua o 10% a i ʻole 5.5% ma lalo o kona kaumaha kumu, i helu ʻia me kona lōʻihi a me kona kaumaha o kēlā me kēia lōʻihi.
ʻAʻole e ʻokoʻa ke anawaena o waho ma mua o ±1% mai ka anawaena waho i koho ʻia.
ʻAʻole ʻoi aku ka mānoanoa o ka pā ma kēlā me kēia wahi ma mua o 12.5% ​​ma lalo o ka mānoanoa pā i kuhikuhi ʻia.

Ka lōʻihi

Nā lōʻihi like ʻole: 16 a 25ft(4.88 a 7.62m)
ʻElua mau lōʻihi like ʻole: ma luna o 25ft a 35ft(7.62 a 10.67m)
Nā lōʻihi like ʻole: ʻae ʻia ka hoʻololi ʻana ±1in

Hoʻopau

E hoʻolako ʻia nā puʻu paipu me nā wēlau maʻamau, a e hoʻoneʻe ʻia nā pahu ma nā wēlau
Ke pau ka hopena o ka paipu i ʻōlelo ʻia he bevel, ʻo ka huina o 30 a 35 degere

ʻO kekahi o nā pōmaikaʻi nui o ka hale welded i hoʻokumu ʻia i ke anuanupaipu no ka wiliwiliʻo kona hiki ke pale i nā wela kiʻekiʻe a me nā pilikia.ʻAʻole like me nā paipu maʻamau, hiki ke hoʻopili ʻia i ka corrosion a me nā ʻano hoʻohaʻahaʻa ʻē aʻe, ua hana ʻia nā paipu anu i hana ʻia e kū i ka paʻakikī o ka welding a me nā hana ʻoihana ʻē aʻe.ʻO kēia ka mea kūpono iā lākou no ka hoʻohana ʻana i nā ʻano noi like ʻole mai ke kūkulu hale a i nā hana ʻoihana.

ʻO kekahi pono o ka paipu welded welded structural paipu i kona kumu kūʻai.Hiki i ke kaʻina hana anuanu ke hana i nā paipu i nā ʻano nui a me nā ʻano like ʻole, e hōʻemi ana i ka pono no ka hoʻolei ʻana a me nā kaʻina hana mīkini.ʻO kēia ka mea e ʻoi aku ka maʻalahi o ka huahana a me ka hilinaʻi e like me ka paipu ʻole a welded.Eia kekahi, ʻo ke ʻano māmā o ka paipu i hana ʻia i ke anuanu e maʻalahi ai ka lawe ʻana a me ka hoʻokomo ʻana a ʻoi aku ka maikaʻi o ke kumukūʻai, e hoʻonui hou ana i kona hoʻopiʻi.

Loaʻa ka pōmaikaʻi o nā paipu humuhumu spiral mai ke kaʻina hana anu.ʻO ka ikaika a me ka maʻalahi o nā paipu anu i hana ʻia i kūpono no ka hana ʻana i nā hui spiral lōʻihi a leak-proof.ʻO kēia ke koho maikaʻi loa no nā noi e like me nā ʻōnaehana hoʻoheheʻe ma lalo o ka honua, nā laina wai a me nā ʻōnaehana irrigation mahiʻai.Hoʻohui ʻia, ʻo ka maʻemaʻe o nā paipu i hana ʻia i ke anuanu e hōʻemi i ka pilikia o ka friction a me ka ʻaʻahu, hoʻonui i ke ola paipu a hōʻemi i ka pono no ka mālama ʻana a me ka hoʻoponopono ʻana.

ʻO ka holoʻokoʻa, hāʻawi ka paipu welded welded structural paipu i nā mea maikaʻi e lilo ai i koho maikaʻi loa no nā noi wili, ʻoi aku ka paipu spiral seam pipe.ʻO ko lākou ikaika, ka lōʻihi a me ka maikaʻi o ke kumukūʻai e lilo lākou i mea koho maikaʻi no nā ʻano ʻoihana ākea, mai ke kūkulu ʻana a hiki i ka hana ʻana.Ke hoʻomau nei ka ulu ʻana o nā mea pono kiʻekiʻe, ʻoi aku ka maikaʻi o nā mea hilinaʻi, e lilo ka paipu welded welded structural paipu i kahi koho kaulana no nā noi wili.
