Paipu kila kuhiliʻole no ka maikaʻi

Sanitary grade seamless kuhiliʻole paipu hana kaʻina hana steelmaking - olokaʻa poepoe kila - perforation - anu kiʻi - anu olokaʻa - malamalama annealing - loko ili polihing - waho ili polihing - ka nana a me ka ae ana - puʻe waihona. 

ʻO ka hale hana o ka sanitary grade seamless stainless steel paipu mai ke kaha anu. Ma ka wehewehe ʻana o kekahi mau lako kī: 1, mīkini kiʻi paipu anu: ke kila poepoe i hoʻoheheʻe ʻia ma hope o ke kapa ʻia ʻana o ka paipu, ʻo ka paipu maʻamau ф 65*5mm a i ʻole ф 100*7mm. 

ʻO ka paipu kila maʻemaʻe maʻemaʻe maʻamau mai ka ф 14 * 1mm a i ka ф 200 * 3mm, no laila ka pono e hoʻonui i ka paipu a huki i ka paipu liʻiliʻi, ka mīkini huki anu e hoʻokō. I kekahi manawa, pono e hoʻonui ʻia ka paipu a i ʻole nā ​​tubules, ʻoiai e hana ʻia ana ka annealing (heat treatment) a me nā pōʻai pickling. ʻAʻole i wehewehe ʻia nā ʻano a me nā kikoʻī o ka mīkini huki huki anu a me nā ʻano mandrel a me nā kikoʻī. ʻO nā pōmaikaʻi nui o ke kaha kiʻi anu: ʻoi aku ka maikaʻi o ka hana ʻana; He mea maʻalahi a maʻalahi hoʻi e hoʻololi i nā kikoʻī o ka huahana i ka wā hana. 

ʻO nā mea hana a me ka hanaʻana i nā mea hana a me ka mālamaʻana i ka hale o nā mea hana maʻalahi. ʻO nā hemahema nui o ke kaha kiʻi anuanu: he liʻiliʻi ka deformation o ka pass, no laila ʻoi aku ka nui o ka pass process, lōʻihi ka pōʻaiapili hana; He kiʻekiʻe ka hoʻohana metala. Hoʻopau maikaʻi ʻole ma ka ʻili o loko a me waho o ka paipu. 2. Multi-roll ka paipu anuanu ʻo ka mīkini: ʻo ia ka mea kī nui e hana ai i ka sanitary seamless stainless steel pipe ma Kina. ʻO ke anawaena o waho a me ka mānoanoa o ka pā o ka paipu kila i huki ʻia ma lalo o 0.02-0.05mm ma hope o ka ʻōwili anu.

ʻO ka hoʻopau ʻana i loko a me waho o ka paipu ʻo Ra≤0.8μm, a hiki ke hana ʻia ka mānoanoa o ka pā i 0.5mm. Ma hope o ka polishing, hiki i ka ʻili o loko a me waho o ka paipu ke hiki i Ra≤0.2-0.4μm (e like me ke aniani). ʻAʻole i wehewehe ʻia nā ʻano a me nā kikoʻī o ka multi-roll cold pipe rolling mill a me nā ʻano mandrel a me nā kikoʻī.

 ʻO ka pōʻino nui loa o ka paipu i ʻōwili ʻia he kūlana paʻakikī, ʻo ia hoʻi, nui ka ikaika o ka coefficient flexion, ʻaʻole kūpono ia no ka hoʻonui ʻana, kūlou, ʻōlelo koʻikoʻi, a ʻaʻole i kūpono i nā kūlana aupuni, no laila pono e hoʻokō. hoʻopaʻa paʻa wela (annealing). Ma keʻano laulā, mālama ʻia ka paipu kila kuhiliʻole e ka umu hoʻoheheʻe wela maʻamau (ke kapuahi waiu), ʻo ka unahi oxide ma loko a ma waho o ka paipu e pono ai ka pickling, kahi e hoʻopau ai i ka pau ʻana o ka ʻili o loko a me waho o ka paipu anu i ʻōwili ʻia, a ʻO ke ʻano o ka liʻiliʻi liʻiliʻi ʻole, ʻaʻole i hiki i ka pae hoʻomaʻemaʻe o ka pae hoʻopau maʻamau. No laila, pono e koho ʻia ka pale kinoea.
