AISI ASTM Puʻupuʻu hoʻohiwahiwa ʻole SS Tubes 321 Kuhili ʻole ʻili Paipu

ʻO ka hana ili o ka paipu kila kila he NO.1, 2B, No. 4, HL, No. 6, No. 8, BA, TR paʻakikī, Rerolled bright 2H, polishing bright and other surface finishes, etc.

NO.1: No. 1 ili e pili ana i ka ili i loaʻa ma ka wela wela a me ka pickling ma hope o ka wela olokaa o ka kuhiliʻole kila paipu. ʻO ia ka wehe ʻana i ka unahi ʻeleʻele oxide i hana ʻia i ka wā o ka ʻōwili wela a me ka mālama ʻana i ka wela ma ka pickling a i ʻole nā ​​ʻano lapaʻau like. ʻO kēia ka No. He keʻokeʻo keʻokeʻo a matt ka ʻili No. Hoʻohana nui ʻia i nā ʻoihana wela a me ka corrosion-resistant ʻaʻole pono i ka gloss surface, e like me ka ʻoihana waiʻona, ʻoihana kemika a me nā ipu nui.

2B: He ʻokoʻa ka ʻili o 2B mai ka ʻili 2D no ka mea, ua hoʻomaʻamaʻa ʻia me ka ʻili maʻemaʻe, no laila ʻoi aku ka mālamalama ma mua o ka ʻili 2D. ʻO ka waiwai o Ra roughness ʻili i ana ʻia e ka mea hana he 0.1~0.5μm, ʻo ia ke ʻano hana maʻamau. ʻO kēia ʻano o ke kila kila kila ka mea maʻalahi loa, kūpono no nā kumu maʻamau, i hoʻohana nui ʻia i ka kemika, ka pepa, ka aila, ka lāʻau lapaʻau a me nā ʻoihana ʻē aʻe, a hiki ke hoʻohana ʻia ma ke ʻano he pā pale hale.

TR Paʻa Paʻa: Ua kapa ʻia ʻo TR stainless steel he kila paʻakikī. ʻO 304 a me 301 kona mau kila kila, hoʻohana ʻia lākou no nā huahana e koi ai i ka ikaika kiʻekiʻe a me ka paʻakikī, e like me nā kaʻa kaʻaahi, nā kāʻei conveyor, nā pūnāwai a me nā gaskets. ʻO ke kumumanaʻo ka hoʻohana ʻana i nā ʻano hana paʻakikī o ka austenitic stainless steel e hoʻonui i ka ikaika a me ka paʻakikī o ka pā kila e nā ʻano hana anu e like me ka ʻōwili. Hoʻohana ka mea paʻakikī i kekahi mau pākēneka a hiki i nā ʻumi o ka pākēneka o ka ʻōwili māmā e pani i ka palahalaha mālie o ka ʻili kumu 2B, a ʻaʻohe hana hoʻopili ma hope o ka ʻōwili ʻana. No laila, ʻo ka TR paʻakikī ʻili o ka mea paʻakikī i ʻōwili ʻia ma hope o ka ʻōwili anuanu.

Rerolled Bright 2H: Ma hope o ke kaʻina hana. ka paipu kila kuhiliʻole e hana ʻia i ka annealing. Hiki ke hoʻomaloʻo wikiwiki ʻia ka paipu e ka laina annealing mau. ʻO ka holo wikiwiki o ka paipu kila kila ma ka laina ma kahi o 60m ~ 80m / min. Ma hope o kēia ʻanuʻu, e hoʻopili hou ʻia ka 2H o ka ʻili.

No. 4: ʻO ka ʻili o ka No. ke kumu a me ka polishing me ke kāʻei abrasive me ka nui o ka palaoa o 150-180 # ʻili mīkini. ʻO ka waiwai o ka ʻilikai Ra i ana ʻia e ka mea hana he 0.2~1.5μm. Hoʻohana nui ʻia ka ʻili NO.4 i ka hale ʻaina a me nā lako kīhini, nā mea lapaʻau, nā mea hoʻonaninani hale, nā ipu, etc.

HL: Kapa ʻia ka ʻili HL i ka pau ʻana o ka lauoho. Ua ʻōlelo ʻo Japanese JIS maʻamau e hoʻohana ʻia ke kāʻei abrasive 150-240 # e hoʻopololei i ka ʻili abrasive e like me ka lauoho mau. Ma ke kūlana GB3280 o Kina, ʻaʻole maopopo nā lula. Hoʻohana nui ʻia ka hoʻopau ʻana o ka HL no ke kūkulu hale e like me nā elevators, escalators, a me facades.

No.6: Hoʻokumu ʻia ka ʻili o ka No. 6 ma luna o ka ʻili o ka No. 4 a ua hoʻomaʻamaʻa hou ʻia me kahi palaki Tampico a i ʻole mea abrasive me ka nui o W63 i kuhikuhi ʻia e GB2477 standard. Loaʻa i kēia ʻili kahi luster metala maikaʻi a me ka hana palupalu. Ua nāwaliwali ka noʻonoʻo ʻana a ʻaʻole i hōʻike i ke kiʻi. Ma muli o kēia waiwai maikaʻi, kūpono loa ia no ka hana ʻana i nā pā hale kūkulu hale a me ke kūkulu ʻana i nā mea hoʻonaninani fringe, a hoʻohana nui ʻia hoʻi e like me nā mea kīhini.

BA: ʻO BA ka ʻili i loaʻa ma ka mālama ʻana i ka wela ma hope o ka ʻōwili anu. Hoʻopili ʻia ka lāʻau wela mālamalama ma lalo o kahi lewa pale e hōʻoiaʻiʻo ʻaʻole ʻoki ʻia ka ʻili no ka mālama ʻana i ka ʻōlinolino o ka ʻili anuanu, a laila hoʻohana i kahi roll smoothing kiʻekiʻe no ka pae māmā e hoʻomaikaʻi i ka ʻōlinolino o ka ʻili. Kokoke keia ili i ke aniani hoopau, a o ka roughness ili Ra waiwai i anaia e ka mea hana he 0.05-0.1μm. He nui ka hoʻohana ʻana o ka ʻili BA a hiki ke hoʻohana ʻia e like me nā lako kīhini, nā mea pono hale, nā mea lapaʻau, nā ʻāpana kaʻa a me nā mea hoʻonaninani.

No.8: No.8 mea he aniani-ho'opau 'ili me ka kiekie reflectivity me ka abrasive hua. Kāhea ʻia ka ʻoihana hoʻoheheʻe hohonu i ke kila kila he mau papa 8K. ʻO ka maʻamau, hoʻohana ʻia nā mea BA e like me nā mea maka no ke aniani hoʻopau wale ʻana ma o ka wili a me ka polishing. Ma hope o ka hoʻopau ʻana i ke aniani, ʻano kiʻi ka ʻili, no laila e hoʻohana nui ʻia i ke kūkulu ʻana i ka hoʻonani komo a me ka hoʻonani o loko.
