Dej ntsev Corrosion & Vuam: 5083 vs 5086 Aluminium Piping Systems
Corrosion Resistance nyob rau hauv Marine Environments
Ob lub alloys tsim kom muaj zog, tus kheej - kho oxide txheej uas tiv thaiv chloride nres hauv dej hiav txwv. Nyob rau hauv cov dej ntsev tsis tu ncua, ob qho tib si 5083 thiab 5086 piping systems muab lub neej kev pab ntau tshaj 30 xyoo. Thaum kuaj tshuaj ntsev ntsev (ASTM G85) qhia 5083 muaj qhov qis qis qis qis, 5086 yog qhov tsim nyog rau 95% ntawm marine cooling, ballast, thiab cov kav dej huv.
Welding Performance (Qhov tseem ceeb sib koom)
Nyob rau hauv lub siab piping, lub welded sib koom ua ke yog qhov limiting tsim yam tseem ceeb. Ob lub alloys weld zoo heev siv TIG (GTAW) thiab MIG (GMAW) txheej txheem.
- Weld Strength: Raws li ASME Tshooj VIII siab lub nkoj lis dej num, 5083 welded pob qij txha muab lub zog tensile ntawm 285-300 MPa, thaum 5086 welds feem ntau ua tiav 261 MPa.
- Filler Hlau: Siv ER5183 muab tub lim rau 5083 txhuas yeeb nkab kom phim lub zog hlau. Siv ER5356 rau kev cai 5086 txhuas piping tshuab.
Cryogenic Performance rau LNG Thauj
Tsis zoo li cov pa roj carbon steel kav, uas tau dhau los ua cov ductile - mus rau - kev hloov pauv thiab tawg ntawm sub- xoom kub, ob qho tib si 5083 thiab 5086 txhuas raj tau txais lub zog thaum khaws cov khoom zoo ntawm -162℃(-260℃F).
- 5083 dominates lub lag luam cryogenic piping vim nws lub zog ntau dua, tso cai rau kev thauj mus los sib dua rau Liquefied Natural Gas (LNG).
Kev Ntsuas Tus Nqi & TCO rau 5086 thiab 5083 Txhuas Siab Yeeb Nkab
- Khoom siv:Vim yog cov ntsiab lus alloying ntau dua thiab kev tswj xyuas nruj dua, lub siab -lub zog 5083 aluminium extruded raj feem ntau hais kom tus nqi 3% mus rau 8% tus nqi tshaj nws cov 5086 counterpart.
- Tus Nqi Tag Nrho Cov Tswv Cuab (TCO):Yog tias koj qhov kev tsim cov kav dej tso cai rau cov phab ntsa nyias nyias siv 5083, qhov kev txo qis ntawm tag nrho cov khoom hnyav tuaj yeem cuam tshuam qhov siab dua rau -kg tus nqi. Txawm li cas los xij, yog tias phab ntsa thickness tau hais los ntawm cov txheej txheem yeeb nkab cov sij hawm es tsis yog qhov tseeb ntawm kev ntxhov siab, 5086 muab tus nqi tam sim ntawd zoo dua.
Daim ntawv qhia: Qhov twg siv 5083 vs 5086 Aluminium Tube
Txhawm rau txhim kho kev nyab xeeb thiab kev siv nyiaj txiag, cov kws tshaj lij txawj ntse qhia txog txoj cai alloy rau txoj cai kav dej:
