ʻO ka maʻamau, hana ʻia ʻo VJ Piping me ke kila kila me 304, 304L, 316 a me 316Letc. Ma ʻaneʻi e hoʻolauna pōkole mākou i nā ʻano o nā mea kila kila.
SS304
Hoʻokumu ʻia ʻo 304 stainless steel pipe e like me ke kūlana ʻAmelika ASTM o kahi hōʻailona kila kila.
ʻO 304 paipu kila kila e like me kā mākou 0Cr19Ni9 (OCr18Ni9) paipu kila kila.
Hoʻohana nui ʻia ʻo 304 stainless steel tube e like me ke kila kila i nā lako meaʻai, nā lako kemika maʻamau, a me ka ʻoihana ʻenehana atomic.
ʻO 304 paipu kila kila he paipu kila kila honua, hoʻohana nui ʻia ia i ka hana ʻana i ka hana holoʻokoʻa maikaʻi (corrosion resistance and formability) lako a me nā ʻāpana.
ʻO 304 paipu kila kila ka mea hoʻohana nui ʻia ke kila kila, ke kila wela. Hoʻohana ʻia i nā lako hana meaʻai, nā mea kemika maʻamau, ka ikehu nuklea, etc.
304 paipu kila kuhiliʻole kemika haku mele C, Si, Mn, P, S, Cr, Ni, (Nickel), Mo.
Kūleʻa kila 304 a me 304L ʻokoʻa hana
304L ʻoi aku ka pale ʻana i ka corrosion, ʻo 304L ka liʻiliʻi o ke kalapona, ʻo 304 he kila kuhili honua, a hoʻohana nui ʻia ia i ka hana ʻana i nā mea hana a me nā ʻāpana e koi ana i ka hana piha maikaʻi (ka pale ʻana a me ka formability). ʻO 304L kahi ʻano like ʻole o 304 stainless steel me ka haʻahaʻa carbon content a hoʻohana ʻia no nā noi wili. ʻO ka maʻiʻo kalapona haʻahaʻa e hoʻemi i ka ua carbide i loko o ka wahi wela kokoke i ka weld, hiki ke alakaʻi i ka corrosion intergranular (welding erosion) i ke kila kila ma kekahi mau kaiapuni.
Hoʻohana nui ʻia ʻo 304, me ke kūpaʻa corrosion maikaʻi, ka pale wela, ka ikaika haʻahaʻa haʻahaʻa a me nā waiwai mechanical; ʻO ka hoʻomaʻamaʻa wela maikaʻi, e like me ke kuʻi ʻana a me ke kulou ʻana, me ka ʻole o ka mālama ʻana i ka wela (ʻaʻohe magnetic, me ka hoʻohana ʻana i ka mahana -196 ℃-800 ℃).
He kūpaʻa maikaʻi loa ka 304L i ka corrosion palena o ka palaoa ma hope o ke kuʻi ʻana a i ʻole ka hoʻoluhi koʻikoʻi: hiki iā ia ke mālama i ke kūpaʻa maikaʻi ʻana me ka ʻole o ka mālama ʻana i ka wela, ka mahana hana -196 ℃-800 ℃.
SS316
ʻO 316 kila kila maikaʻi nō hoʻi nā waiwai chloride erosion, no laila hoʻohana mau ʻia ia i nā kaiapuni moana.
ʻO ka hale hana paipu kila kuhiliʻole kūpaʻa
ʻOi aku ka maikaʻi o ka corrosion ma mua o 304 stainless steel, i ka hana ʻana o ka pulp a me ka pepa he kūpaʻa maikaʻi.
A ʻo ka 316 stainless steel ka mea kūʻē i ka moana a me nā ʻenehana ʻoihana koʻikoʻi. ʻO ke kūpaʻa wela ma 1600 degere ma lalo o ka hoʻohana hoʻopau ʻana a ma 1700 degere ma lalo o ka hoʻohana mau ʻana, 316 ke kila kila maikaʻi ke kūpaʻa oxidation.
Ma ka laulā o 800-1575 degere, ʻoi aku ka maikaʻi ʻaʻole e hoʻohana mau i ka 316 stainless steel, akā i ka pae wela ma waho o ka hoʻohana mau ʻana o 316 stainless steel, maikaʻi ke kila kila.
ʻOi aku ka maikaʻi o ka carbide precipitation resistance o 316 stainless steel ma mua o ka 316 stainless steel a hiki ke hoʻohana ʻia i ka pae wela o luna.
316 kuhiliʻole kila i maikai kuʻihao hana. Hiki ke wili ʻia me ka hoʻohana ʻana i nā ʻano wili maʻamau āpau. Hiki ke hoʻohana ʻia ka welding e like me ka hoʻohana ʻana o 316Cb, 316L a i ʻole 309CB stainless steel filler rod a i ʻole electrode welding. No ka loaʻa ʻana o ke kūpaʻa corrosion maikaʻi loa, e hoʻopili ʻia ka ʻāpana welded o 316 stainless steel ma hope o ke kuʻi ʻana. ʻAʻole koi ʻia ka hoʻopili ʻana ma hope o ka weld inā hoʻohana ʻia ke kila kila 316L.
Nā mea hoʻohana maʻamau: nā mea hoʻololi wela o ka pulp a me ka pepa, nā mea pena, nā lako hana kiʻiʻoniʻoni, nā paipu, a me nā mea hana no ka waho o nā hale kūlanakauhale ma nā kahakai.
ʻAi ʻAi ʻAi ʻAi Maikaʻi
Me ka ulu ʻana o ka hoʻokele waiwai, ʻo ke kila kila i ka ʻoihana meaʻai, nā lawelawe ʻai a me ka hoʻohana ʻana i ke ola ʻohana e ʻoi aku ka nui a ʻoi aku ka nui, ua manaʻo ʻia ma waho aʻe o nā mea hale kila kila a me nā papa ʻaina, ʻālohilohi a maʻemaʻe e like me nā hiʻohiʻona hou, akā loaʻa nō hoʻi ka maikaʻi o ka mildew, antibacterial, ka hana sterilization.
E like me kā mākou e ʻike ai, ʻo kekahi mau metala, e like me ke kālā, ke keleawe, ka bismuth a me nā mea ʻē aʻe he antibacterial, bactericidal effect, ka mea i kapa ʻia ʻo antibacterial stainless steel, i loko o ke kila kila e hoʻohui i ka nui o nā mea me ka hopena antibacterial (e like me ke keleawe, ke kālā), ka hana ʻana o ke kila ma hope o ka hoʻomaʻamaʻa wela antibacterial, me ka hana hana antibacterial a maikaʻi.
ʻO ke keleawe ka mea nui o ka antibacterial, ʻo ka nui o ka hoʻohui ʻana ʻaʻole pono e noʻonoʻo i ka waiwai antibacterial, akā e hōʻoiaʻiʻo hoʻi i nā waiwai hana maikaʻi a paʻa o ke kila. 'Oko'a ka nui o ke keleawe me nā 'ano kila. Hōʻike ʻia ka haku mele ʻana o ke kila kila antibacterial i hoʻomohala ʻia e Japanese Nissin Steel ma ka Papa 10. Hoʻohui ʻia ka 1.5% keleawe i ke kila ferritic, 3% i ke kila martensitic a me 3.8% i ke kila austenitic.
