Sisebenzisa iikuki ukuphucula amava akho.Ngokuqhubeka nokukhangela le ndawo, uyavumelana nokusebenzisa kwethu iikuki.Iinkcukacha ezithe xaxe.
Intshayelelo, uthelekiso lweMathiriyeli yokuVelisa uKunyamezelwa koDonga Ukutyeba kweDayamitha yaNgaphandle yoMphezulu woKugqibezela uNyango lwe-Weld Bead lobushushu
Eli nqaku libonelela ngenye ikhowudi yeenkonzo zokutya zase-Australia.Ezi nkcukacha ziquka:
I-ASTM A269 "Inkcazo yeNjongo ngokuPhangaleleyo engenamthungo kunye neWelded Austenitic Stainless Steel Tubing"
I-ASTM A249 "Inkcazo ye-Austenitic Boiler, i-Superheater, i-Heat Exchanger, kunye ne-Condenser Welded Tubes"
I-AS1528 yahlaziywa ngo-2001 ngabachaphazelekayo abaphambili kushishino lwase-Australia lokutya kunye nemibhobho.I-AS 1528 yahlukile kuba igquma zonke izifakelo ezifanelekileyo ngaphandle kwemibhobho.
Zonke iinkcukacha zibhekisela kumabakala ensimbi aqhelekileyo afana ne-304, 304L, 316 kunye ne-316L.I-AS1528.1 isebenza kuwo onke amabakala entsimbi ephindwe kabini kunye ne-austenitic edweliswe kwi-ASTM A240.
Zonke iisayizi zifuna iimveliso ze-fusion-welded ngaphandle kwentsimbi yokuzalisa.Iinkcukacha ezifana ne-ASTM A270, ASTM A269 kunye ne-AS 1528 nazo ziyasebenza kwiimveliso ezingenamthungo.
I-AS 1528 ichaza ubukhulu begama obuyi-1.6 mm kuzo zonke iidayamitha zangaphandle (OD) ngaphandle kwe-2 mm kwi-203.2 mm ngaphandle kwedayamitha;obunye ubungqingqwa bunokuchazwa ngumthengi.Ukunyamezela okusemgangathweni + zero, -0.10 mm.Ukunyamezela okupheleleyo okungalunganga kuthetha umkhuba oqhelekileyo wokuvelisa imibhobho yazo zonke iisayizi ezikufutshane nomda ophantsi woluhlu lokunyamezela.Uluhlu oluqhelekileyo luyi-1.52 ukuya kwi-1.58 mm.Olu kunyamezela lusebenza nakwizifakelo.
* Ukunyamezela iimeko zokususa i-weld ASTM A554.* I-AS1528 iyasebenza nakwi-OD ubukhulu be-12.7, 19.0, 31.8, 127.0, 152.4 kunye ne-203.2 mm.
Zonke ezi nkcukacha zemibhobho zichaza imida yobunzima bodonga kunye nobubanzi bangaphandle.I-diameter yangaphakathi ayichazwanga ngokwahlukileyo.
Inkcazo yonyango olungaphezulu lweesayizi ezahlukeneyo ezicetyiswayo ukuba zisetyenziswe kwishishini lokutya lase-Australia zimi ngolu hlobo lulandelayo:
Ukucutshungulwa kweemveliso ezisetyenziswa kwishishini lokutya kufuna imibhobho ngaphandle kweentsalela ze-weld kumphezulu wangaphakathi.
Iipropathi zoomatshini zamanqanaba ahlukeneyo entsimbi engatyiwayo eqhelekileyo esetyenziswa kushishino lokutya zezi zilandelayo:
I-AZoM ithethe noDkt. Katharina Marquardt phambi koSuku lwaMazwe ngaMazwe lwabasetyhini kunye namantombazana kwiSayensi kwi-2023. Sixoxa nge-STEM yakhe ekhangayo yomsebenzi othatha amava kwiinkalo ezivela kwi-mineralogy ukuya kwizinto ze-ceramic.
Ngomhla waMazwe ngamazwe abasetyhini kunye namantombazana kwiSayensi, i-AZoM ixoxa ngophando lwakhe lwe-STEM kunye nomsebenzi kunye noDkt.
Kulo dliwano-ndlebe, i-AZoM yayinomdla wokuthetha noDkt Julia Galli, uNjingalwazi kwiYunivesithi yaseChicago kunye noSayensi oPhezulu kwi-Argonne National Laboratory, malunga nomsebenzi wakhe wesayensi omangalisayo.
I-APEX 400 sisisombululo esizinikeleyo sokulungiselela amaso okwenziwa ngesandla kuhlalutyo lwe-XRF.Iyakwazi ukucinezela iisampuli kumakhonkco entsimbi axhaswayo kunye nobukhulu obungaxhaswanga.
Funda ngakumbi malunga nendlela yokunyusa ukusebenza kakuhle kwelebhu yakho ngeLabVantage 8.8, isikhangeli sewebhu sorhwebo ukuze ufikelele kulo lonke ulwazi lwelebhu yakho.
Esi sishwankathelo semveliso sibonelela ngamagqabantshintshi endlela yokusebenzisa i-NIR spectroscopy kuhlolo lwenkqubo oluthembekileyo.
Imarike ye-semiconductor yehlabathi ingene kwixesha elinomdla.Imfuno yeteknoloji ye-chip ikhuthaze kwaye yabambezela uphuhliso lweshishini, kwaye ukunqongophala kwe-chip kulindeleke ukuba kuqhubeke ixesha elithile.Iintsingiselo zangoku zinokubumba ikamva loshishino njengoko oku kuqhubeka
Umahluko ophambili phakathi kweebhetri ezisekelwe kwigraphene kunye neebhetri eziqinileyo kukubunjwa kwee-electrodes.Nangona ii-cathodes zihlala ziguqulwa, i-allotropes yekhabhoni ingasetyenziselwa ukwenza i-anodes.
Kwiminyaka yakutshanje, i-Intanethi yeZinto iphunyezwe ngokukhawuleza phantse kuzo zonke iindawo, kodwa ibaluleke kakhulu kwishishini lezithuthi zombane.
