Mau Oyamba Mafotokozedwe Kuyerekeza Zipangizo Kupanga Kulekerera kwa Miyeso Kukhuthala kwa Khoma M'mimba mwake wakunja Kumaliza kwa Weld Bead Kutentha Katundu wa Makina Kuyesa Kosawononga Zomwe Zimatanthauza
Nkhaniyi ikupereka njira ina yopezera ntchito zamakampani azakudya ku Australia. Mafotokozedwe oterewa akuphatikizapo:
ASTM A269 “Kufotokozera kwa Chitoliro Chosapanga Chitsulo ...
ASTM A249 “Mafotokozedwe a Boiler ya Chitsulo cha Austenitic Welded, Superheater, Heat Exchanger, ndi Condenser Tubes”
AS1528 idasinthidwanso mu 2001 ndi okhudzidwa kwambiri mumakampani opanga chakudya ndi machubu aku Australia. AS 1528 ndi yapadera chifukwa imakhudza zolumikizira zonse zofunikira kupatula machubu.
Masayizi onse ndi ofanana monga magiredi 304, 304L, 316 ndi 316L. AS1528.1 imakhudza mitundu yonse ya zitsulo zosapanga dzimbiri za duplex ndi austenitic zomwe zalembedwa mu ASTM A240.
Masayizi onse amafuna zinthu zolumikizidwa popanda chitsulo chodzaza. Mafotokozedwe monga ASTM A270, ASTM A269 ndi AS 1528 amakhudzanso zinthu zopanda msoko.
AS 1528 imatchula makulidwe odziwika a 1.6mm pa mainchesi onse akunja (OD) koma 2 mm pa OD ya 203.2 mm; makulidwe ena angatchulidwe ndi wogula. Kulekerera kokhazikika ndi +nil, -0.10mm. Kulekerera kopanda pake kwathunthu ndi kofala pamitundu yonse ya mapaipi, ndipo kumapangidwa kumapeto kwa gawo lolekerera. Mtundu wamba ndi pakati pa 1.52 ndi 1.58 mm. Kulekerera kumeneku kumagwiranso ntchito pa zolumikizira mapaipi.
* ASTM A554 Kulekerera kwa zinthu zochotsera weld.*AS1528 imakhudzanso kukula kwa OD 12.7, 19.0, 31.8, 127.0, 152.4 ndi 203.2mm
Mafotokozedwe onse a chitolirochi amapereka makulidwe a khoma ndi malire a mainchesi akunja. Mainchesi amkati sanatchulidwe padera.
Makhalidwe osiyanasiyana okongoletsa pamwamba omwe akulangizidwa ndi Food Industry Services Australia ndi awa:
Zinthu zotsukira zomwe zimagwiritsidwa ntchito mumakampani ogulitsa chakudya zimafuna mapaipi opanda zotsalira za weld pamwamba pa mkati.
Kapangidwe ka makina a mitundu yosiyanasiyana ya zitsulo zosapanga dzimbiri zomwe zimagwiritsidwa ntchito kwambiri mumakampani azakudya ndi motere:
AZoM adalankhula ndi Dr. Iolanda Duarte ndi Juliane Moura za kafukufuku wawo, womwe umaganizira za kupezeka kwa zomera za extremophile pa mapanelo a photovoltaic.
AZoM adalankhula ndi Pulofesa Andrea Fratalocchi wa KAUST za kafukufuku wake, womwe umayang'ana kwambiri mbali zomwe sizinadziwike kale zokhudza malasha.
Mwa kuphatikiza ultrasound, kugwedezeka, kutentha ndi liwiro lozungulira, SDT340 imakulolani kuyang'anira thanzi la makina, kulosera mavuto ndikuchepetsa ndalama zamagetsi. Gwiritsani ntchito limodzi ndi pulogalamu yowunikira ya UAS3 kuti muwongolere zotsatira ndikukonza njira yanu yowunikira momwe zinthu zilili.
Ichi ndi chojambula cha mkuwa chopangidwa ndi JX Nippon Mining & Metals chomwe chili ndi kusinthasintha kwabwino komanso kukana kugwedezeka.
X100-FT ndi mtundu wa X-100 Universal Tester wopangidwira kuyesa ulusi. Komabe, kapangidwe kake ka modular kamalola kusintha mitundu ina yoyesera.
Mphamvu ya dzuwa yakhala patsogolo pakupanga ukadaulo watsopano m'maiko, ndipo asayansi nthawi zonse amafunafuna njira zatsopano zopangira njira zopangira mphamvu moyenera.
Nkhaniyi ifufuza njira yatsopano yomwe ili ndi kuthekera kopanga zinthu zopangidwa ndi zinthu zina zomwe zili ndi kulondola kwa sub-10 nm.
Pepala ili likufotokoza za kukonzekera kwa ma BCNT opangidwa ndi catalytic thermal chemical vapor deposition (CVD), zomwe zimapangitsa kuti pakhale kusamutsa kwachangu pakati pa ma electrode ndi ma electrolyte.
