Sisebenzisa amakhukhi ukuthuthukisa ulwazi lwakho.Ngokuqhubeka upheqa lesi sizindalwazi uyavumelana nokusetshenziswa kwethu kwamakhukhi.Ulwazi olwengeziwe.
Imininingwane Yesingeniso Izinto Zokuqhathanisa Ukukhiqiza Ukubekezelela Okunobukhulu Bodonga Ubukhulu Bangaphandle Udayamitha Ubuso Qeda Ukwelashwa Kokushisa Kwe-Weld Bead Izakhiwo Zemishini Ukuhlola Okungonakali Iyiphi Incazelo
Lesi sihloko sinikeza okunye ukucaciswa kwamasevisi embonini yokudla yase-Australia.Izincazelo ezinjalo zihlanganisa:
I-ASTM A269 “Izicaciso Zepayipi Lensimbi Engenamthungo ne-Welded Austenitic Stainless Stainless Steel”
I-ASTM A249 “Ukucaciswa kwe-Welded Austenitic Steel Boiler, Superheater, Heat Exchanger, kanye nama-Condenser Tubes”
I-AS1528 yabuyekezwa ngo-2001 ababambiqhaza ababalulekile embonini yokukhiqiza ukudla yase-Australia kanye neshubhu.AS 1528 ihlukile ngoba ihlanganisa konke ukufakwa okuhlobene ngaphandle kwamashubhu.
Bonke osayizi bangamabanga avamile njengamabanga 304, 304L, 316 kanye no-316L.AS1528.1 afaka wonke amamaki e-duplex nezinsimbi ezingenasici ze-austenitic ezisohlwini lwe-ASTM A240.
Bonke osayizi badinga imikhiqizo ehlanganisiwe eshiselwe ngaphandle kwe-filler metal.Izincazelo ezifana ne-ASTM A270, ASTM A269 kanye ne-AS 1528 nazo zihlanganisa imikhiqizo engenamthungo.
I-AS 1528 icacisa ubukhulu begama obungu-1.6mm kuwo wonke amadayamitha angaphandle (OD) kodwa u-2 mm ku-203.2 mm OD;okunye ukujiya kungase kucaciswe umthengi.Ukubekezelela okujwayelekile kungu-+nil, -0.10mm.Ukubekezelelana okungalungile ngokuphelele kuwumkhuba ovamile kubo bonke osayizi bamapayipi, futhi kukhiqizwa ekugcineni okuphansi kwebanga lokubekezelelana.Ububanzi obujwayelekile buphakathi kuka-1.52 no-1.58 mm.Lokhu kubekezelela kuyasebenza nasekufakweni kwamapayipi.
* I-ASTM A554 Ukubekezelela izimo zokususa i-weld.*AS1528 futhi ifaka osayizi be-OD 12.7, 19.0, 31.8, 127.0, 152.4 kanye no-203.2mm
Zonke lezi zicaciso zamapayipi zinikeza ukushuba kodonga kanye nemikhawulo yobubanzi obungaphandle.Ububanzi bangaphakathi abukhulunywanga ngokwehlukana.
Izakhiwo ezahlukahlukene zokuqeda ezinconywe yiFood Industry Services Australia zimi kanje:
Imikhiqizo yokwelapha esetshenziswa embonini yokudla idinga amapayipi angenayo insalela ye-weld endaweni engaphakathi.
Izakhiwo zemishini zamabanga ahlukahlukene ensimbi engagqwali avame ukusetshenziswa embonini yokudla zimi kanje:
I-AZoM ikhulume noDkt. Iolanda Duarte noJulianne Moura mayelana nocwaningo lwabo, olucabangela ukuba khona kwe-extremophile flora kumaphaneli e-photovoltaic.
I-AZoM ikhulume noSolwazi we-KAUST u-Andrea Fratalocchi mayelana nocwaningo lwakhe, olugxile ezintweni ezazingaziwa ngaphambilini zamalahle.
Ngokuhlanganisa i-ultrasound, ukudlidliza, izinga lokushisa nesivinini sokujikeleza, i-SDT340 ikuvumela ukuba uqaphe impilo yomshini, ubikezele izinkinga futhi unciphise izindleko zamandla.Yisebenzise ngokuhambisana nesofthiwe yokuhlaziya ye-UAS3 ukuze uphathe imiphumela futhi uhlele isu lakho lokuqapha isimo.
Lena i-JX Nippon Mining & Metals' ucwecwe lwethusi olugoqiwe olujwayelekile olunokuguquguquka okuhle nokumelana nokudlidliza.
I-X100-FT inguqulo ye-X-100 Universal Tester eyenzelwe ukuhlola i-fiber.Nokho, ukwakheka kwayo kwe-modular ivumela ukuzivumelanisa nezinye izinhlobo zokuhlola.
Amandla elanga abehamba phambili ekuthuthukiseni ubuchwepheshe obusha emazweni, futhi ososayensi bahlale befuna izindlela ezintsha zokuthuthukisa izinhlelo ezisebenzayo zokukhiqiza amandla.
Lesi sihloko sizohlola indlela entsha enamandla yokuklama ama-nanomaterials ngokunemba kwe-sub-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.
