FAQ
Q1: Kuv puas yuav tsum xaiv C71500 lossis C70600 rau cov kav dej hiav txwv?
Xaiv C71500 rau siab - dej hiav txwv ceev (siab dua 3.5 m/s) thiab C70600 rau qis tshaj tawm.C71500 (70/30) muaj 30% npib tsib xee nrog lub zog siab dua (UTS 54-60 ksi vs C70600 ntawm 45-55 ksi) thiab zoo dua erosion kuj. C70600 (90/10) yog kev lag luam ntau dua tab sis txwv rau 3-3.5 m / s ntws. Rau cov ntawv thov naval SUBSAFE xav tau cov npoo ntxiv, C71500 nyiam dua txawm tias tus nqi siab dua.
Q2: Qib 1 SUBSAFE txhais li cas rau C71500 tooj liab yeeb nkab?
Qib 1 SUBSAFE qhia txog tus qauv zoo tshaj plaws rau cov txheej txheem tseem ceeb hauv nkoj nkoj.Qhov no txhais tau hais tias C71500 cov yeeb nkab tooj liab tau dhau los ua cov ntaub ntawv nruj, kev sim, thiab cov ntaub ntawv xav tau. Cheebtsam uas tuaj yeem ua rau dej nyab lossis poob ntawm lub nkoj nkoj yuav tsum tau ntawv pov thawj Qib 1. Ib txwm qhia SUBSAFE Theem 1 rau kev siv nkoj nkoj submarine.
Q3: Qhov txawv ntawm C71500 raj thiab C71500 yeeb nkab yog dab tsi?
Tube yog teev los ntawm qhov tseeb OD thiab phab ntsa tuab; yeeb nkab yog teev los ntawm nominal loj thiab lub sij hawm.Rau C71500 tooj liab raj, ASTM B111 siv (OD feem ntau 3/8 "rau 1"). Rau C71500 tooj liab yeeb nkab, ASTM B466 siv (nominal 1/4 "rau 12", teem sij hawm 40/80). Ob leeg yog seamless. Tube feem ntau yog siv rau condensers thiab tshav kub exchangers; cov yeeb nkab rau cov kav dej hiav txwv dav dav.
Q4: Dab tsi yog qhov ceev ntawm C71500 cov khoom siv rau kev ntsuas qhov hnyav?
C71500 ceev yog 0.323 lb/in³ (8.94 g/cm³).Rau C71500 tooj liab yeeb nkab luj ib ko taw: (OD - phab ntsa) × phab ntsa × 10.68=lb/ft. Piv txwv li: 1" OD × 0.065" phab ntsa=0.65 lb/ft. Rau metric: (OD mm - phab ntsa mm) × phab ntsa mm × 0.028=kg/m. Qhov no yog qhov tseem ceeb rau kev yuav khoom thiab kev xam lub nkoj hnyav.
Q5: C71500 puas tuaj yeem txuas rau C70600?
Yog lawm, C71500 tuaj yeem txuas rau C70600 siv ERNi-7 muab tub lim hlau.Ob leeg yog tooj liab -nickel alloys nrog zoo compatibility. Siv TIG vuam nrog ERNi-7 muab tub lim thiab argon rov qab tshem tawm. Lub weld cheeb tsam yuav muaj cov khoom ntawm ob lub alloys. Rau daim ntawv thov SUBSAFE, ua raws cov txheej txheem vuam pom zoo.
Q6: Dab tsi yog qhov sib npaug European tus qauv rau C71500?
EN 12451 CW354H yog European sib npaug rau C71500 raj.Kuj tau xaiv CuNi30Mn1Fe lossis 2.0882. Rau cov haujlwm nyob sab Europe, qhia CW354H rau EN 12451 (tube) lossis EN 12163 (rod / bar). Ib txwm thov daim ntawv pov thawj dual (ASTM + EN) rau cov haujlwm thoob ntiaj teb.
Q7: Vim li cas C71500 xav tau cov ntsiab lus hlau ntawm 0.4-1.0%?
Hlau (0.4-1.0%) yog xav tau rau kev yaig tsis kam hauv cov dej hiav txwv ntws.Yog tsis muaj hlau txaus, qhov kev tiv thaiv zaj duab xis ntawm C71500 tsis ruaj khov. Rau C71500 tooj liab yeeb nkab nyob rau hauv siab -ceev seawater (4-5 m / s), hlau cov ntsiab lus yuav tsum tau xyuas nyob rau hauv daim ntawv pov thawj zeb xeem. Txais cov khoom siv nrog Fe qis yuav ua rau muaj kev cuam tshuam ntxov ntxov.
Q8: C71500 piv rau 316 stainless hlau rau seawater li cas?
C71500 muaj cov seawater corrosion kuj zoo dua li 316 stainless hlau thiab tiv thaiv chloride kev nyuaj siab corrosion cracking.316 stainless hlau tuaj yeem raug kev txom nyem pitting thiab SCC nyob rau hauv dej hiav txwv sov, tshwj xeeb tshaj yog nyob rau hauv stagnation los yog qis - tej yam kev mob ntws. C71500 tooj liab npib tsib xee tuav ntau dua velocities thiab muaj ntuj bio-fouling kuj. Txawm li cas los xij, 316 SS muaj zog dua. Rau cov kav dej, C71500 feem ntau nyiam.
Q9: Dab tsi yog qhov kev xa khoom zoo rau C71500 tooj liab yeeb nkab?
C71500 tooj liab yeeb nkab feem ntau yog muab annealed (OS035) los yog lub teeb kos (OS025).OS035 yog tag nrho annealed - zoo tshaj plaws rau khoov, flaring, thiab raj expansion. OS025 muaj zog dua (60 ksi UTS, 25 ksi tawm los) rau cov yeeb nkab ncaj nraim. Qhia qhov kub ntawm koj daim ntawv xaj khoom. Rau cov ntawv thov SUBSAFE, cov ntaub ntawv pov thawj thiab cov ntawv xeem yuav tsum tau khaws cia.
Q10: Puas yog C71500 haum rau siab -kub condensers?
Yog lawm, C71500 khaws lub zog mus txog 350℃(662℃F) rau kev pabcuam condenser.Melting ntau yog 1170-1240 degree. Cov ntawv thov feem ntau suav nrog lub zog cog condensers thiab feedwater heaters nrog inlet kub ntawm 200-280 degree. Rau qhov kub siab tshaj 350 degree, lub zog txo qis thiab lwm yam khoom siv yuav tsum xav txog.
