Imininingwane Yesingeniso Izinto Zokuqhathanisa Ukukhiqiza Ukubekezelelana Okulinganayo Ubukhulu Bodonga Ububanzi Bangaphandle Ukuqeda Komphezulu I-Weld Bead Ukwelashwa Kokushisa Izakhiwo Zemishini Ukuhlolwa Okungonakalisi Yikuphi Ukucaciswa
Lesi sihloko sinikeza incazelo ehlukile yezinsizakalo zemboni yokudla yase-Australia. Imininingwane enjalo ifaka:
I-ASTM A269 “Imininingwane Yepayipi Lensimbi Engagqwali Elijwayelekile Elingenamthungo Nelihlanganisiwe Lase-Austenitic”
I-ASTM A249 “Imininingwane ye-Welded Austenitic Steel Boiler, i-Superheater, i-Heat Exchanger, kanye nama-Condenser Tubes”
I-AS1528 yabuyekezwa ngo-2001 ngababambiqhaza ababalulekile embonini yokukhiqiza ukudla kanye namapayipi e-Australia. I-AS1528 ihlukile ngoba ihlanganisa zonke izinto ezidingekayo ngaphandle kwamapayipi.
Osayizi bonke bangamazinga avamile njengebanga 304, 304L, 316 kanye ne-316L. I-AS1528.1 ihlanganisa wonke amazinga ezinsimbi ezingenalutho ze-duplex kanye ne-austenitic ezibhalwe ku-ASTM A240.
Osayizi bonke badinga imikhiqizo ehlanganisiwe ehlanganisiwe ngaphandle kwensimbi yokugcwalisa. Imininingwane efana ne-ASTM A270, ASTM A269 kanye ne-AS 1528 nayo ihlanganisa imikhiqizo engenamthungo.
I-AS 1528 icacisa ubukhulu obujwayelekile obungu-1.6mm kuzo zonke ububanzi bangaphandle (OD) kodwa obungu-2 mm ku-OD engu-203.2 mm; obunye ubukhulu bungachazwa ngumthengi. Ukubekezelelana okujwayelekile kungu-+nil, -0.10mm. Ukubekezelelana okunegebe ngokuphelele kuyindlela evamile kubo bonke osayizi bepayipi, futhi kukhiqizwa ekugcineni okuphansi kobubanzi bokubekezelelana. Ububanzi obujwayelekile buphakathi kuka-1.52 no-1.58 mm. Lokhu kubekezelelana kusebenza nasezintweni zokufakelwa kwamapayipi.
* I-ASTM A554 Ukubekezelela izimo zokususwa kwe-weld.* I-AS1528 iphinde ihlanganise osayizi be-OD abangu-12.7, 19.0, 31.8, 127.0, 152.4 kanye no-203.2mm
Zonke lezi zincazelo zamapayipi zinikeza ukujiya kodonga kanye nemikhawulo yobubanzi bangaphandle. Ububanzi bangaphakathi abukhulunywa ngabodwa.
Izakhiwo ezahlukahlukene zokuqeda ubuso ezinconywe yi-Food Industry Services Australia yilezi ezilandelayo:
Imikhiqizo yokwelapha esetshenziswa embonini yokudla idinga amapayipi angenazo izinsalela zokushisela ebusweni bangaphakathi.
Izakhiwo zemishini zezinhlobo ezahlukene zensimbi engagqwali ezivame ukusetshenziswa embonini yokudla yilezi ezilandelayo:
I-AZoM ikhulume noDkt. Iolanda Duarte noJuliane Moura mayelana nocwaningo lwabo, olubheka ukuba khona kwezitshalo ezikhula ngokushesha kumaphaneli e-photovoltaic.
I-AZoM ikhulume noSolwazi u-Andrea Fratalocchi we-KAUST mayelana nocwaningo lwakhe, olugxile ezicini ezazingaziwa ngaphambili zamalahle.
Ngokuhlanganisa i-ultrasound, ukudlidliza, izinga lokushisa kanye nesivinini sokujikeleza, i-SDT340 ikuvumela ukuthi uqaphe impilo yomshini, ubikezele izinkinga futhi unciphise izindleko zamandla. Yisebenzise kanye nesofthiwe yokuhlaziya ye-UAS3 ukuphatha imiphumela nokuhlela isu lakho lokuqapha isimo.
Lena yi-JX Nippon Mining & Metals' i-foil yethusi egoqiwe ejwayelekile enokuguquguquka okuhle kanye nokumelana nokudlidliza.
I-X100-FT inguqulo ye-X-100 Universal Tester eyenzelwe ukuhlolwa kwefayibha. Kodwa-ke, ukwakheka kwayo kwe-modular kuvumela ukuzivumelanisa nezinye izinhlobo zokuhlola.
Amandla elanga abelokhu ehamba phambili ekuthuthukiseni ubuchwepheshe obusha emazweni, futhi ososayensi bahlala befuna izindlela ezintsha zokuthuthukisa izinhlelo zokukhiqiza amandla eziphumelelayo.
Lesi sihloko sizohlola indlela entsha enamandla okuklama izinto ezincane ngokunemba okungaphansi kwe-10 nm.
Leli phepha libika ukulungiswa kwama-BCNT okwenziwa nge-catalytic thermal chemical vapor deposition (CVD), okuholela ekudlulisweni kweshaja okusheshayo phakathi kwama-electrode nama-electrolyte.
