FAQ
Q1: Qhov twg zoo dua rau cov kav dej hiav txwv, C71500 lossis C70600?
C71500 yog qhov zoo dua rau siab -ceev seawater yeeb nkab.Nws muaj 30% npib tsib xee vs 10% hauv C70600, tsim cov yeeb yaj kiab tiv thaiv zoo dua. C70600 yeeb nkab muaj kev nyab xeeb txog 3-3.5 m / s, thaum C71500 tooj liab yeeb nkab tuav 4-5 m / s yam tsis muaj kev puas tsuaj. Rau turbulent yeeb nkab khiav nrog khoov, xaiv C71500.
Q2: Dab tsi yog European sib npaug ntawm C71500 raj?
EN 12451 CW354H yog qhov sib npaug European.Kuj tau xaiv 2.0882 lossis CuNi30Fe1Mn. Cov txheej txheem no suav nrog qhov ntev, cov khoom siv kho tshuab, thiab kev sim rau cov raj kub hloov pauv. Ib txwm thov dual ASTM / EN ntawv pov thawj rau cov haujlwm xa tawm.
Q3: Kuv puas tuaj yeem siv C71500 yeeb nkab rau naval seawater hydraulic kab?
Yog, nws yog dav siv rau naval hydraulic thiab hluav taws xob lub ntsiab.Teem sijhawm 40 C71500 yeeb nkab muaj 60-70% kev ua haujlwm siab ntawm carbon steel ib ASME B31.3. Nws cov kev tiv thaiv corrosion thiab bio-fouling tiv thaiv ua rau nws nyiam txawm tias qis dua lub zog.
Q4: Dab tsi yog qhov kub siab tshaj plaws rau asme sb111 c71500 raj?
Qhov siab tshaj plaws ua haujlwm kub yog 350℃(662℃F).Nyob rau hauv tas li ntawd, creep zog txo. Hom chav condenser inlet yog 200-280 degree, zoo nyob rau hauv ntau yam kev nyab xeeb. Kev mus ncig luv luv mus rau 400℃yog zam tau tab sis yuav ua rau lub raj muag muag.
Q5: Kuv yuav xam qhov hnyav ntawm 70/30 tooj liab nickel yeeb nkab li cas?
Siv ceev 0.325 lb/in³ (8950 kg/m³).Formula: (OD - phab ntsa) × phab ntsa × 10.68=lb/ft. Rau 1" OD × 0.065" phab ntsa: 1 - 0.065=0.935; 0.935 × 0.065=0.0608; 0.0608 × 10.68=0.65 lb/ft. Tiv tauj peb rau daim ntawv qhia qhov hnyav.
Q6: Puas yog asme sb466 c71500 npog U-khoov raj?
Tsis yog, nws npog seamless ncaj kav dej nkaus xwb.Rau U- khoov, tib yam khoom siv tab sis khoov yuav tsum ua tau raws li ASME Tshooj VIII. Yuav tsum tau tov annealed temper thiab phab ntsa thinning Tsawg dua los yog sib npaug rau 10%. Qhia U- khoov cov cai ntawm koj daim ntawv xaj yuav khoom.
Q7: Dab tsi vuam muab tub lim rau C71500 yeeb nkab kom tsis txhob tawg?
Use ERNi-7 (AWS A5.14) or RNi-7 filler metal.Tsis txhob siv ERCuNi tooj liab -nickel fillers - lawv ua rau kub tawg. ERNi-7 muaj 4% hlau thiab 1.5% manganese, muab kev ntub dej zoo thiab tawg ua haujlwm. Tsis muaj preheat rau phab ntsa Tsawg dua los yog sib npaug li 5 hli.
Q8: Kuv puas tuaj yeem txuas C71500 yeeb nkab ncaj qha rau carbon steel hauv dej hiav txwv?
Tsis yog, kev sib txuas ncaj qha ua rau cov hlau galvanic corrosion sai.C71500 yog ntau noble (cathodic). Siv cov khoom siv insulating flange, nruab ib lub roj hmab hose spool (10-15 yeeb nkab diameters), los yog muab zinc anodes rau sab steel. Tsis txhob siv cov kev sib txuas ncaj qha los yog welded.
Q9: Dab tsi yog qhov tawg siab ntawm C71500 tooj liab yeeb nkab?
Siv Barlow's formula: P=(2 × S × t) / OD.S=UTS (310 MPa min). Rau 1 "OD × 0.065" phab ntsa ntawm chav tsev kub: (2 × 310 × 1.65mm) / 25.4mm=approx 3000 psi. Ntawm 200 degree, derate lub zog los ntawm 15%. Nrog ASME B31.3 rau kev tso cai ua haujlwm siab.
Q10: Cov thermal conductivity ntawm C71500 piv rau C12200 li cas?
C71500 muaj li 1/12 lub thermal conductivity ntawm C12200.C71500=29.3 W/mK; C12200=340-360 W/mK. Lower conductivity txhais tau tias txo cov cua sov hloov mus, tab sis superior seawater corrosion kuj outweighs qhov no rau marine heat exchangers.
