Sanitary grade seamless kuhiliʻole paipu hana kaʻina hana steelmaking - olokaʻa poepoe kila - perforation - anu kiʻi - anu olokaʻa - malamalama annealing - kūloko ili polihing - waho ili poli - ka nana a me ka ae ana - puʻe waihona.
ʻO ka hale hana o ka sanitary grade seamless stainless steel paipu mai ke kiʻi anu.Ma ka wehewehe ʻana o kekahi mau lako kī: 1, mīkini huki paipu anu: kila poepoe i hoʻoheheʻe ʻia ma hope o ke kapa ʻia ʻana o ka paipu, ʻo ka paipu maʻamau he 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 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 hoʻokō 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 anuanu 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 keʻano o nā mea hana maʻalahi.ʻO nā hemahema nui o ke kaha kiʻi anu: 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 anu paipu wili mīkini: 'o ia ke kī lako e hana sanitary seamless kuhiliʻole kila paipu 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 ʻōwili anuanu he kūlana paʻakikī, ʻo ia hoʻi, ʻo ka ikaika o ka flexion coefficient he nui, ʻaʻole kūpono ia no ka hoʻonui ʻana, kūlou, ʻōlelo koʻikoʻi, a ʻaʻole i kūpono i nā kūlana aupuni, no laila pono e hoʻokō. lapaʻau paʻa wela (annealing).Ma keʻano laulā, mālama ʻia ka pahu kila kuhiliʻole e ka umu hoʻoheheʻe wela maʻamau (ka umu 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 anuanu ʻōwili mua, a ke ʻano o ka liʻiliʻi liʻiliʻi ʻole, ʻaʻole i hiki i ka pae maʻemaʻe o ka pae hoʻopau o ka paipu.No laila, pono e koho ʻia ka pale kinoea.
ʻOi aku ka liʻiliʻi o ka 50% hao a me 10.5% chromium, a hoʻohui pū kekahi e like me ka nickel, titanium, molybdenum, a me nā mea ʻē aʻe, e like me nā ʻāpana ʻokoʻa i loaʻa i ke koena, ʻokoʻa hoʻi ka microstructure metala. nona ke kino martensite, kino ferrite, kino austenitic, papalua, ua paʻakikī kila kila.Loaʻa nō hoʻi nā paipu kila kuhili ʻole ma ka papa maʻemaʻe i nā mea like ʻole.ʻO ka ʻoihana maʻamau i hoʻohana mau ʻia ka mea ʻoi aku ka nui o ka tube austenitic stainless steel;0Cr19Ni9 (USU304), 00Cr19Ni11 (USU 304L), 0Cr17Ni12Mo2 (USU 316), 00Cr17Ni14Mo2 (USU 316L), 1Cr18Ni9Ti (SUS 321), etc. No ka hoʻokō ʻana i ka paipu stainless steel /-T497 maʻamau ʻole ʻo GB /-T9. a me nā koi hoʻopau o loko a me waho o ka paipu kila.E koho i nā paipu kila kuhili ʻole maʻemaʻe me ke ʻano o ka wai, ka ʻike, ka mahana, ke kaomi, ka wikiwiki o ke kahe, a me nā mea ʻē aʻe.
