ʻOi aku ka maikaʻi o ka puʻupuʻu, ʻoi aku ka ikaika ma mua o ka paipu welded ERW.No laila ua hoʻohana nui ʻia i nā mea hana kiʻekiʻe, a me ka wela, nā ʻoihana boiler.ʻO ka maʻamau, ʻo ka wili kuʻi ʻana o ka paipu kila welded ka wahi nāwaliwali, ʻo ka maikaʻi e pili ana i ka hana holoʻokoʻa.

ʻO ka paipu wili ʻole me ka paipu kila welded:

1. Okoa ke ano

Ua hoʻohana ʻia ka paipu kila maʻemaʻe ma ke ʻano he mea maka.ʻAʻole hiki ke hoʻopau ʻia nā hemahema o waho o ka billet ma ke kaʻina hana ʻōwili wela, hoʻoliʻi wale ʻia ma hope o ka pau ʻana o ka huahana.I ke kaʻina hana o ka hoʻemi ʻana i ka pā, hiki ke hoʻopau ʻia ka hemahema.

Welded kila paipu i hanaia e ka wela owili wili e like me maka mea, ka ili maikai o ka wili mea wale ka paipu o ka ili maikaʻi, a oluolu e control.
No laila, ʻoi aku ka maikaʻi o Welded steel pipe surface quality ma mua o ka seamless steel pipe.

2. ʻokoʻa Kaʻina Molding
Hiki ke hana ʻia ka paipu kila seamless i hoʻokahi manawa ma ke kaʻina ʻōwili.
Hana ʻia ka paipu kila welo me ke kaula kila a i ʻole ka pā kila, ma o ke kuʻi ʻana a me nā kaʻina hana kuʻi ʻokoʻa.

3. Hana a hoʻohana
ʻOi aku ka maikaʻi o ka ikaika o ka paipu kila ʻole, ʻoi aku ka ikaika ma mua o ka paipu welded ERW.No laila ua hoʻohana nui ʻia i nā mea hana kiʻekiʻe, a me ka wela, nā ʻoihana boiler.
ʻO ka maʻamau, ʻo ka wili kuʻi ʻana o ka paipu kila welded ka wahi nāwaliwali, ʻo ka maikaʻi e pili ana i ka hana holoʻokoʻa.

Ma keʻano laulā, hiki i nā paipu kila welded ke kāohi i ka 20% ka emi o ka hana ma mua o nā mea ʻole.ʻO kēia hilinaʻi ke kumu nui e hele ai nā kānaka no ka paipu kila ʻole.ʻO ka ʻoiaʻiʻo, ua hana ʻia nā pipeline ʻoihana āpau me nā paipu seamless wale nō no ka mea e loaʻa ana nā paipu i nā hana wela, kemika a me ka mīkini.ʻOi aku ka maikaʻi o nā paipu welded ma nā ʻoihana aerospace, kaʻa a me nā ʻenehana uila kahi i haʻahaʻa haʻahaʻa ai ka waihona kālā, a pēlā pū ke kaomi hana ma luna o nā paipu.

4. Loaʻa nā ʻokoʻa
No ka hapa nui o nā mea hana paipu kila maʻemaʻe ma Kina, hana lākou i ka nui o ka nui o ka paipu seamless OD ma 20 iniha, 508 mm.Ma kahi maʻamau, ʻoi aku ka liʻiliʻi ma mua o 16 iniha, 406.4 mm, no ka palena o nā lako.A inā makemake ka mea kūʻai aku e kūʻai i ka paipu kila maʻemaʻe ma mua o ka nui o luna, a laila e hoʻohana ʻia ka mīkini hoʻonui wela.Akā ma ka maʻamau, ʻaʻole hiki ke hoʻohālikelike ʻia ka maikaʻi o kēia ʻano wela wela i hoʻonui ʻia me ka paipu kila ʻole.

ʻAʻole i loaʻa kēia mau palena, nā nui i loaʻa mai 1-1/2 iniha 48.3mm a 100 iniha 2540 mm.

5.Kumukuaiʻokoʻa
ʻO ka mea maʻamau, ʻoi aku ka kiʻekiʻe o ke kumukūʻai o ka paipu kila ma mua o nā paipu kila welded, no ka mea, ʻo ka mea maka, nā lako hana a me nā kaʻina hana.Akā i kekahi manawa ma ke kaomi mākeke, ʻoi aku ke kumukūʻai o ka paipu welded, no laila inā ʻoe e hālāwai me kēia kūlana, mai kānalua e kūʻai i ka paipu kila ʻole no nā ana like.
