Kab lus no muab lwm txoj cai rau Australian cov kev pabcuam zaub mov.Cov specifications no muaj xws li:
ASTM A269 Specification rau General Purpose Seamless and Welded Austenitic Stainless Steel Tubing
ASTM A249 Specification rau Austenitic Boiler, Superheater, Kub Exchanger, thiab Condenser Welded Tubes
AS1528 tau hloov kho hauv xyoo 2001 los ntawm cov neeg muaj feem tseem ceeb hauv Australian zaub mov thiab yeeb nkab kev lag luam.AS 1528 yog qhov tshwj xeeb uas nws npog tag nrho cov fittings tshwj tsis yog cov kav dej.
Tag nrho cov kev qhia tshwj xeeb yog xa mus rau cov qib steel xws li 304, 304L, 316 thiab 316L.AS1528.1 siv rau tag nrho cov duplex thiab austenitic stainless hlau qib teev nyob rau hauv ASTM A240.
Txhua qhov ntau thiab tsawg yuav tsum tau fusion-welded khoom yam tsis muaj hlau muab tub lim.Cov lus qhia tshwj xeeb xws li ASTM A270, ASTM A269 thiab AS 1528 kuj tseem siv tau rau cov khoom siv seamless.
AS 1528 qhia lub nominal thickness ntawm 1.6 hli rau tag nrho cov sab nraud diameters (OD) tsuas yog 2 hli rau 203.2 hli sab nraud txoj kab uas hla;Lwm cov thicknesses yuav raug teev los ntawm tus neeg yuav khoom.Standard kam rau ua + xoom, -0.10 hli.Qhov siab tsis zoo tag nrho txhais tau hais tias qhov kev coj ua ntawm kev tsim cov kav dej ntawm txhua qhov ntau thiab tsawg ze rau qhov qis qis ntawm qhov kev kam rau siab.Feem ntau yog 1.52 txog 1.58 hli.Qhov kev kam rau siab no kuj siv tau rau fittings.
* Kev kam rau siab rau ASTM A554 weld tshem tawm cov xwm txheej.* AS1528 kuj tseem siv tau rau OD qhov ntau thiab tsawg 12.7, 19.0, 31.8, 127.0, 152.4 thiab 203.2 hli.
Tag nrho cov yeeb nkab tshwj xeeb no qhia txog kev txwv ntawm phab ntsa thickness thiab sab nraud txoj kab uas hla.Sab hauv txoj kab uas hla tsis qhia cais.
Cov txheej txheem kho deg ntawm ntau qhov ntau thiab tsawg pom zoo rau siv hauv Australian kev lag luam khoom noj muaj raws li hauv qab no:
Kev ua cov khoom siv hauv kev lag luam khoom noj khoom haus yuav tsum muaj cov kav dej uas tsis muaj qhov seem ntawm cov khoom seem ntawm sab hauv.
Cov khoom siv kho tshuab ntawm ntau qib ntawm stainless hlau feem ntau siv hauv kev lag luam zaub mov yog raws li hauv qab no:
Hauv kev xam phaj no, Chris Nicholas tham txog cov cuab yeej siv hluav taws xob uas ua kom muaj kev ruaj ntseg ntawm acrylic acid thiab acrylates.Cov kev tshawb fawb tau tshoov siab startup Låkril Technologies Corporation, uas lub hom phiaj rau kev lag luam thev naus laus zis.
Hauv kev xam phaj no, AZoM tham nrog Evident's Ted Shields txog tus tshiab Vanta™ GX XRF analyzer.Shields piav qhia txog Vanta GX cov txiaj ntsig thiab kev siv.
Hauv kev xam phaj no, AZoM tham nrog Bo Preston, tus tsim ntawm Rainscreen Consulting, hais txog STRONGIRT, qhov kev txhawb nqa zoo tshaj plaws rau kev txuas txuas txuas txuas ntxiv (CI) cladding thiab nws cov ntawv thov.
OIM Matrix™ software pob, muaj raws li kev xaiv rau OIM Analysis ™, tso cai rau tus neeg siv los ua qauv EBSD cov qauv raws li lub zog hluav taws xob diffraction physics.
Orton's rotating axis viscometers tau tsim los ntsuas qhov viscosity ntawm molten iav ntawm ntau qhov kub thiab txias.
Kev lag luam thoob ntiaj teb semiconductor tau nkag mus rau lub sijhawm zoo siab.Kev thov rau cov tshuab chip muaj ob qho tib si spurred thiab retarded txoj kev loj hlob ntawm kev lag luam, thiab tam sim no chip tsis txaus yuav tsum tau mus ntxiv rau qee lub sij hawm.Cov qauv tam sim no yuav ua rau lub neej yav tom ntej ntawm kev lag luam raws li qhov no txuas ntxiv mus
Qhov sib txawv tseem ceeb ntawm graphene-raws li roj teeb thiab cov roj teeb hauv lub xeev yog cov muaj pes tsawg leeg ntawm cov electrodes.Txawm hais tias cathodes feem ntau hloov kho, allotropes ntawm carbon kuj tuaj yeem siv los ua anodes.
Nyob rau hauv xyoo tas los no, Is Taws Nem ntawm Yam tau ua tiav sai hauv yuav luag txhua qhov chaw, tab sis nws tseem ceeb tshwj xeeb hauv kev lag luam tsheb hluav taws xob.
