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 inoa o 1.6 mm no nā anawaena waho a pau (OD) koe wale 2 mm no 203.2 mm anawaena waho;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 e hōʻike ana i ka hana maʻamau o ka hana ʻana i nā paipu o nā nui āpau kokoke i ka palena 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:
No ka hana ʻana i nā huahana i hoʻohana ʻia i ka ʻoihana meaʻai, pono nā paipu me 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:
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, ua kamaʻilio ʻo AZoM me Dr. Debrupa Lahiri, Associate Professor ma ka Department of Metallurgy and Materials Science ma IIT Roorkee, e pili ana i kāna noiʻi a me kāna hana ma STEM.
Ma kēia nīnauele, ua hauʻoli ʻo AZoM e kamaʻilio pū me Kauka Julia Galli, Kumu ma ke Kulanui o Chicago a me ʻEpekema Nui ma Argonne National Laboratory, e pili ana i kāna ʻoihana ʻepekema kupaianaha.
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 e pili ana i ka hoʻonui ʻana i ka pono o kāu lab me LabVantage 8.8, kahi polokalamu kele pūnaewele ʻoihana, e kiʻi i kāu ʻike āpau.

Hoʻolālā ʻia ka mea hoʻohālikelike 3D particle CAMSIZER® no ka ʻike paʻakikī o nā mea nui.
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.
