Hoʻohana mākou i nā kuki e hoʻomaikaʻi i kou ʻike.Ma ka hoʻomau ʻana i kēia pūnaewele, ʻae ʻoe i kā mākou hoʻohana ʻana i nā kuki.ʻIke hou aku.

Hāʻawi kēia ʻatikala i kahi code ʻē aʻe no nā lawelawe meaʻai Australia.Aia kēia mau kikoʻī:
ʻO ASTM A269 "Specification for General Purpose Seamless and Welded Austenitic Stainless Steel Tubing"
ASTM A249 "Specification no Austenitic Boiler, Superheater, Heat Exchanger, a me Condenser Welded Tubes"
Ua hoʻoponopono hou ʻia ʻo AS1528 i ka makahiki 2001 e nā mea kuleana nui i ka ʻoihana meaʻai a me ka paipu o Australia.He kū hoʻokahi ʻo AS 1528 no ka uhi ʻana i nā pono kūpono a pau koe nā paipu.
ʻO nā kikoʻī āpau e pili ana i nā māka kila maʻamau e like me 304, 304L, 316 a me 316L.Hoʻopili ʻia ka AS1528.1 i nā papa kila kila kila a pau i helu ʻia ma ASTM A240.
Pono nā nui āpau i nā huahana fusion-welded me ka ʻole o ka metala hoʻopiha.Hoʻopili ʻia nā kikoʻī e like me ASTM A270, ASTM A269 a me AS 1528 i nā huahana seamless.
Hōʻike ka AS 1528 i ka mānoanoa helu o 1.6 mm no nā anawaena waho a pau (OD) koe wale 2 mm no OD 203.2 mm;hiki ke kuhikuhi ʻia nā mānoanoa ʻē aʻe e ka mea kūʻai aku.Ka hoʻomanawanui maʻamau + zero, -0.10 mm.ʻO ka hoʻomanawanui maikaʻi ʻole i ka laina me ka hana maʻamau no ka hana ʻana i nā paipu o nā nui āpau kokoke i ka hopena haʻahaʻa o ka pae hoʻomanawanui.ʻO ka laulā maʻamau he 1.52 a 1.58 mm.Pili pū kēia ʻae ʻana i nā mea pono.
* Hoʻomanawanui no nā kūlana wehe weld ASTM A554.* Pili pū ka AS1528 i nā nui OD 12.7, 19.0, 31.8, 127.0, 152.4 a me 203.2 mm.
Hōʻike kēia mau kikoʻī paipu i nā palena o ka mānoanoa o ka paia a me ke anawaena o waho.ʻAʻole hoʻokaʻawale ʻia ke anawaena o loko.
ʻO nā kikoʻī lapaʻau o ka ʻili o nā ʻano nui i manaʻo ʻia no ka hoʻohana ʻana i ka ʻoihana meaʻai Australia penei:
Pono ka hana ʻana o nā huahana i hoʻohana ʻia i ka ʻoihana meaʻai i nā paipu me ka ʻole o nā koena weld ma ka ʻili o loko.
ʻO nā waiwai mechanical o nā māka like ʻole o ke kila kuhili ʻole i hoʻohana mau ʻia i ka ʻoihana meaʻai penei:
Ke kamaʻilio nei ʻo AZoM me NanoGraf CEO Francis Wang e kūkākūkā i kā lākou ʻenehana ʻenehana Lithium Ion hou a me ka hana ʻana i waho ma Midwest.
Ua kamaʻilio ʻo AZoM me Kauka Katharina Marquardt ma mua o ka International Day of Women and Girls in Science i ka makahiki 2023. Kūkākūkā mākou i kāna ʻoihana STEM hoihoi e pili ana i ka ʻike ma nā hoʻopaʻapaʻa mai ka mineralogy a i nā mea ceramic.
Ma ka International Day of Women and Girls in Science, kūkākūkā ʻo AZoM i kā lākou noiʻi STEM a me kā lākou hana me Dr. Debrupa Lahiri, Associate Professor of Metallurgy and Materials Science ma IIT Roorkee.
ʻO kēia loiloi huahana mai Microtrac e wehewehe ana i nā mana adsorption kiʻekiʻe o Belsorp Max X.
ʻO APEX 400 kahi hopena i hoʻolaʻa ʻia no ka hoʻomākaukau lima ʻana i nā pahu no ka nānā ʻana XRF.Hiki iā ia ke paʻi i nā laʻana i nā apo kila i kākoʻo ʻia a me nā nui i kākoʻo ʻole ʻia.
E aʻo hou aʻe e pili ana i ka hoʻonui ʻana i ka pono o kāu lab me LabVantage 8.8, kahi polokalamu kele pūnaewele no ka loaʻa ʻana o kāu ʻike āpau.
Ua komo ka mākeke semiconductor honua i kahi manawa hoihoi.ʻO ka noi no ka ʻenehana chip ua hoʻoikaika a hoʻopaneʻe i ka hoʻomohala ʻana o ka ʻoihana, a ke manaʻo nei e hoʻomau ka hemahema o kēia manawa no kekahi manawa.Hiki i nā ʻano o kēia manawa ke hoʻohālikelike i ka wā e hiki mai ana o ka ʻoihana ke hoʻomau nei kēia
ʻO ka ʻokoʻa nui ma waena o nā pihi graphene-based a me nā ʻāpana paʻa paʻa ʻo ia ka haku ʻana o nā electrodes.ʻOiai ua hoʻololi pinepine ʻia nā cathodes, hiki ke hoʻohana ʻia nā allotropes o ke kalapona e hana i nā anodes.
I nā makahiki i hala iho nei, ua hoʻokō wikiwiki ʻia ka Internet of Things ma kahi o nā wahi āpau, akā he mea nui ia i ka ʻoihana kaʻa uila.
