316 Paipu kila kila
Ma kahi o 316L paipu kila kila
ʻO 316L kahi mea kila kila, ʻo AISI 316L ka inoa ʻAmelika e pili ana, a ʻo sus 316L ka inoa Iapana e pili ana.ʻO S31603 koʻu ʻāina, ʻo ka helu maʻamau ʻo 022Cr17Ni12Mo2 (maʻamau hou), a ʻo ka papa kahiko ʻo 00Cr17Ni14Mo2, ʻo ia hoʻi, aia ka nui o Cr, Ni, a me Mo, a ʻo ka helu e hōʻike ana i ka pākēneka kokoke.
ʻO ka nui o ka carbon carbon content o 316 stainless steel pipe he 0.03, hiki ke hoʻohana ʻia i nā noi kahi hiki ʻole ke hana ʻia ka annealing ma hope o ke kuʻi ʻana a koi ʻia ke kūpaʻa corrosion kiʻekiʻe.
316 a me 317 kila kuhiliʻole (e nānā i lalo no nā waiwai o 317 kuhiliʻole kila) he molybdenum-i loko o ke kila kuhiliʻole.
ʻOi aku ka maikaʻi o ka hana holoʻokoʻa o kēia papa kila ma mua o ka 310 a me 304 stainless steel.Ma lalo o nā kūlana wela kiʻekiʻe, i ka wā i emi iho ai ka nui o ka sulfuric acid ma mua o 15% a ʻoi aku ka kiʻekiʻe ma mua o 85%, 316 stainless steel ka nui o nā hoʻohana.
316 pā kila kila, i ʻike ʻia ʻo 00Cr17Ni14Mo2 kūpaʻa ʻino:
ʻOi aku ka maikaʻi o ka corrosion ma mua o 304 stainless steel, a he maikaʻi ke kūpaʻa corrosion i ke kaʻina hana o ka pulp a me ka pepa.
ʻOi aku ka maikaʻi o ka carbide precipitation resistance o 316 stainless steel ma mua o ka 304 stainless steel, a hiki ke hoʻohana ʻia ka pae wela ma luna.
316l kuhiliʻole kila paipu aupuni
ʻO 316L kahi mea kila kila, ʻo AISI 316L ka inoa ʻAmelika e pili ana, a ʻo sus 316L ka inoa Iapana e pili ana.ʻO S31603 koʻu ʻāina, ʻo ka helu maʻamau ʻo 022Cr17Ni12Mo2 (maʻamau hou), a ʻo ka papa kahiko ʻo 00Cr17Ni14Mo2, ʻo ia hoʻi, aia ka nui o Cr, Ni, a me Mo, a ʻo ka helu e hōʻike ana i ka pākēneka kokoke.ʻO ka pae aupuni ʻo GB/T 20878-2007 (ka mana o kēia manawa).
Loaʻa i ka 316L ka nui o nā noi i ka ʻoihana kemika ma muli o kona kūpaʻa maikaʻi loa.ʻO 316L kekahi mea i loaʻa i ka 18-8 type austenitic stainless steel, me 2 a 3% o Mo i hoʻohui ʻia.Ma ke kumu o 316L, nui nā māka kila i loaʻa mai.No ka laʻana, loaʻa ka 316Ti ma hope o ka hoʻohui ʻana i kahi huina o Ti, loaʻa ka 316N ma hope o ka hoʻohui ʻana i kahi huina liʻiliʻi o N, a loaʻa ka 317L ma ka hoʻonui ʻana i ka ʻike o Ni a me Mo.
ʻO ka hapa nui o ka 316L e kū nei ma ka mākeke i hana ʻia e like me ka American Standard.No nā kumu kumu kūʻai, hoʻāʻo maʻamau nā wili kila e hoʻohaʻahaʻa i ka ʻike Ni o kā lākou huahana i ka palena haʻahaʻa.ʻO ka maʻamau ʻAmelika e ʻōlelo nei ʻo ka Ni maʻiʻo o 316L he 10-14%, aʻo ka maʻamau Kepanī e kuhikuhi ana i ka Ni maʻiʻo o 316L he 12-15%.Wahi a ka palena haʻahaʻa, aia kahi ʻokoʻa 2% i ka ʻike Ni ma waena o ka maʻamau ʻAmelika a me ka maʻamau Kepanī, he mea nui loa ia ma ke ʻano o ke kumukūʻai.No laila, pono nā mea kūʻai aku e ʻike maopopo i ke kūʻai ʻana i nā huahana 316L, inā pili nā huahana i nā kūlana ASTM a i ʻole JIS.
ʻO ka ʻike Mo o 316L e hana i kēia kila me ke kūpaʻa maikaʻi loa i ka pitting corrosion a hiki ke hoʻohana pono ʻia i nā wahi i loaʻa iā Cl- a me nā ion halogen ʻē aʻe.No ka mea, hoʻohana nui ʻia ʻo 316L no kāna mau waiwai kemika, ʻoi aku ka haʻahaʻa o nā wili kila no ka nānā ʻana i ka ʻili o 316L (hoʻohālikelike ʻia me 304), a ʻo nā mea kūʻai aku me nā koi kiʻekiʻe e pono e hoʻoikaika i ka nānā ʻana.
Ka mālama ʻana a me ka hoʻomaʻemaʻe ʻana i ke kila kila
Inā lōʻihi ka ʻike ʻana o ke kila kila i ka ea, e lepo nō hoʻi e like me nā mea ʻē aʻe.Ua hōʻike ʻia nā haʻawina ʻelua mau ʻano like ʻole o ka holoi ʻana i ka ua a me ka holoi lima ʻana i kekahi pilina me ka lepo lepo o ke kila kila.ʻO ka mua, e hoʻokomo i hoʻokahi papa kila kila ma ka lewa a ʻo kekahi i loko o ka canopy e nānā i ka hopena o ka holoi ua.ʻO ke kaʻina hana o ka hoʻomaʻamaʻa lima ʻana, ʻo ia ka hoʻohana ʻana i kahi ʻōhuʻu i hoʻopaʻa ʻia i loko o ka wai kopa e hoʻoponopono mau ai i ke kūlana o nā ʻōpala, a ʻo ka manawa he 6 mahina no ka holoi ʻana.ʻO ka hopena, ʻoi aku ka liʻiliʻi o ka lepo ma luna o ka ʻili o nā lau i hoʻoheheʻe ʻia ma mua o nā lau i hoʻoheheʻe ʻia ma nā ʻano ʻelua.No laila, hiki ke hoʻopili ʻia ka wā hoʻomaʻemaʻe no ke kila kila e nā kumu he nui.I ke ola, hiki iā mākou ke hoʻomaʻemaʻe wale i ke kila kila ke hoʻomaʻemaʻe mākou i ke aniani, akā inā ma waho ke kila kila, pono e holoi ʻia ʻelua i ka makahiki.
