FAQ
Q1: Qhov txawv ntawm C71500 CuNi 70/30 thiab C70600 CuNi 90/10 yog dab tsi?
A:C71500 muaj 70% tooj liab thiab 30% npib tsib xee, thaum C70600 muaj 90% tooj liab thiab 10% npib tsib xee. C71500 muaj zog dua (72 ksi vs 52 ksi tensile) thiab zoo dua corrosion kuj nyob rau hauv siab -ceev seawater, tshwj xeeb tshaj yog nyob rau kub siab tshaj 200℃F. C70600 nqi tsawg thiab yog txaus rau ntau marine daim ntaub ntawv. C71500 yog qhov zoo dua rau cov dej nrawm heev, dej hiav txwv txhoj puab heev, thiab kev pabcuam kub dua.
Q2: Vim li cas hlau ntxiv rau C71500 tooj liab-nickel condenser raj?
A:Hlau (0.40-1.00%) yog ntxiv rau C71500 txhawm rau txhim kho kev tiv thaiv kev cuam tshuam kev cuam tshuam (kev yaig-corrosion) thiab txhim kho cov yeeb yaj kiab ruaj khov ntawm lub raj nplaim. Cov hlau hloov kho cov txheej txheem oxide tiv thaiv, ua rau nws ua tau zoo dua thiab tiv taus cov tshuab tshem tawm los ntawm siab - dej los yog xuab zeb. Yog tias tsis muaj hlau txaus, cov raj tooj liab-nickel yuav yaig sai dua hauv cov dej hiav txwv turbulent. Qhov no yog vim li cas C71500 qee zaum hu ua "CuNi 70/30 nrog hlau."
Q3: Dab tsi yog qhov siab tshaj plaws dej hiav txwv tshaj tawm rau ASTM B111 C71500 hlab?
A:C71500 cov raj tuaj yeem ua rau dej hiav txwv velocities txog 12-15 ko taw ib pliag (3.7-4.6 m/s), siab dua C70600 (10-12 ft/s) thiab ntau dua li txhuas tooj dag (8-10 ft/s). Qhov no ua rau C71500 haum rau condenser raj hauv naval ships thiab high-flow fais fab nroj tsuag. Rau qhov siab tshaj 15 ft / s, titanium lossis super austenitic stainless hlau yuav tsum tau. Nco ntsoov xyuas nrog cov chaw tsim khoom rau cov xwm txheej tshwj xeeb.
Q4: Puas yog C71500 tiv taus kev ntxhov siab corrosion (SCC)?
A:Yog lawm, C71500 tooj liab-nickel zoo tiv thaiv kev ntxhov siab corrosion tawg, txawm tias nyob rau hauv ammonia lossis sulfide ib puag ncig uas yuav tawg lwm cov tooj liab xws li txhuas tooj dag lossis tooj dag qhuas. Qhov no yog qhov zoo tshaj plaws rau marine condensers qhov twg ammonia los ntawm kev loj hlob ntawm cov kab mob lom lossis cov tshuaj ntxuav tau tuaj yeem tshwm sim. C71500 tsis xav tau kev tshaj tawm -weld kev ntxhov siab los tiv thaiv SCC.
Q5: Dab tsi yog qhov txawv ntawm O61 thiab HR50 temper rau C71500 raj?
A:O61 yog tag nrho annealed (mos), muaj zog tsawg (52 ksi tensile) thiab siab ductility. HR50 yog kos thiab kev ntxhov siab-relieved (nyuaj), muaj zog dua (72 ksi tensile) tab sis qis elongation (12-15%). HR50 yog siv thaum lub raj xav tau kom tiv taus siab dua lossis cov khoom siv sab nraud. O61 yog siv thaum lub raj yuav nthuav dav rau hauv tubesheets thiab xav tau ductility rau dov. Feem ntau cov condenser raj tau muab rau hauv O61 temper.
Q6: Dab tsi yog qhov sib npaug thoob ntiaj teb ntawm UNS C71500 tooj liab-nickel raj?
A:C71500 sib npaug suav nrog: Suav GB qib BFe30-1-1; British BS CN107; German DIN 2.0882; European EN CuNi30Mn1Fe (CW354H); Japanese JIS C7150. Txhua tus muaj qhov sib xws (29-33% Ni, 0.4-1.0% Fe, tshuav Cu). Nco ntsoov xyuas chemistry vim qee qhov sib npaug muaj qhov sib txawv me ntsis hlau lossis manganese ntau yam. GNEE tuaj yeem muab cov qauv no raws li kev thov.
Q7: C71500 CuNi 70/30 raj puas tuaj yeem siv rau hauv cov dej tsis huv lossis tsis ruaj khov?
A:Yog lawm, C71500 ua tau zoo dua C70600 hauv cov dej qias neeg lossis dej hiav txwv vim tias cov ntsiab lus ntau dua nickel muab kev tiv thaiv zoo rau sulfide-induced corrosion. Nyob rau hauv cov xwm txheej uas tsis muaj sulfides (los ntawm cov organic lwj) tam sim no, C70600 tuaj yeem tsim cov yeeb yaj kiab dub sulfide uas tuaj yeem tawg tawm. C71500 tiv taus ntau dua rau qhov kev tawm tsam no. Rau cov pa phem hnyav los yog tsawg - oxygen seawater, C71500 yog cov khoom siv tooj liab nyiam.
Q8: Lub thermal conductivity ntawm C71500 piv rau C70600 yog dab tsi?
A:C71500 muaj qis thermal conductivity (kwv yees 29 W / m·K) piv rau C70600 (kwv yees 40 W / m·K). Qhov no txhais tau tias C71500 hloov cov cua sov tsawg dua li C70600. Rau kev tsim cov khoom siv hluav taws xob sib txawv, thaj chaw ntau dua (cov raj ntev dua lossis ntau lub raj) yuav xav tau thaum siv C71500 kom ua tiav tib lub luag haujlwm hloov hluav taws xob. Kev lag luam tawm - tawm yog qhov zoo dua corrosion thiab muaj zog dua.
Q9: Yuav tsum kuaj dab tsi rau ASTM B111 C71500 condenser raj?
A:ASTM B111 yuav tsum muaj tshuaj ntsuam xyuas (Ni, Fe, Mn, Cu), tensile test (lub zog thiab elongation), expansion test (ductility for tube rolling), flattening test, grain size test, eddy current or hydrostatic test for to leaks, and dimensional inspection. Cov kev sim uas xaiv tau muaj xws li kev ntsuas kev ntxhov siab seem. GNEE muab cov ntawv tshaj tawm zeb xeem (MTR) lees paub txhua qhov kev xeem uas xav tau rau txhua qhov ntau.
Q10: Puas yog C71500 raj haum rau cov nroj tsuag desalination?
A:Yog lawm, C71500 yog dav siv nyob rau hauv seawater desalination nroj tsuag rau evaporators, distillers, thiab tshav kub exchangers. Cov ntsiab lus siab nickel muab kev tiv thaiv zoo rau siab -kub seawater corrosion, yaig los ntawm flashing brine, thiab impingement los ntawm vapor npuas. Rau ntau-theem flash (MSF) thiab ntau yam-cov nroj tsuag cuam tshuam (MED), C71500 yog cov khoom siv txheem. Rau kev rov qab osmosis (RO) cov nroj tsuag, C71500 yog siv rau hauv cov khoom siv hluav taws xob rov qab thiab cov kav dej sib txuas.
Q11: C71500 cov raj puas tuaj yeem txuas rau tubesheets?
A:Yog lawm, C71500 tuaj yeem welded siv roj tungsten arc vuam (GTAW/TIG) nrog cov khoom siv hlau sib txuam (ERCuNi). Lub raj feem ntau yog thawj zaug nthuav dav (dov) rau hauv cov ntawv raj, tom qab ntawd foob welded. Vuam yuav tsum tau preheating (200-300℃F) thiab qis cua sov input kom tsis txhob kub tawg. Tom qab-weld kev kho cua sov tsis tas yuav tsum tau vim C71500 tsis cuam tshuam rau kev ntxhov siab corrosion tawg. Brazing tsis pom zoo rau cov pob qij txha muaj zog.
Q12: Dab tsi yog daim ntawv thov raug rau ASTM B111 C71500 hlab hauv nkoj?
A:C71500 raj yog siv nyob rau hauv naval thiab coj mus muag nkoj condensers, coolers, thiab tshav kub exchangers uas tuav seawater ntawm lub raj sab. Cov kev siv feem ntau suav nrog lub cav loj hauv dej hiav txwv txias, pab lub cav txias, lub tshuab cua txias hauv nruab nrab, thiab cov khoom xa rov qab vapor condensers ntawm tankers. Lub 70/30 alloy tau teev tseg rau siab -kev ua tau zoo qhov kev ntseeg siab hauv cov dej hiav txwv hnyav yog qhov tseem ceeb. Rau qhov kev xav tau tsawg dua, C70600 (90/10) yog ntau dua.
