SB111 C44300 vs. C70600
C44300 (Admiralty Brass) ua haujlwm ntawm lub hauv paus ntsiab lus ntawm "kev tiv thaiv thiab kev txi." Nws lub hauv paus yog ib qho kev lag luam tooj liab -zinc alloy ( tooj dag). Nws suav nrog kwv yees li 1% tin los txhim kho kev tiv thaiv corrosion thiab tso siab rau qhov muaj pes tsawg leeg ntawm arsenic (Raws li) ua "tshuaj lom" los tiv thaiv kev xaiv leaching ntawm zinc (dezincification). Nyob rau hauv qhov tseeb, nws yog ib tug tsawg - nqi kho kom haum rau marine ib puag ncig los ntawm "tshuaj patching."
C70600 (90-10 Cupronickel) yog tsim los ntawm lub hauv paus ntsiab lus ntawm "evolution thiab adaptation." Nws tso tseg tag nrho cov zinc uas tsis muaj zog, es tsis txhob tsim cov tshuaj muaj zog nrog cov nickel kim dua (Ni). Nws lub ntsiab innovation nyob rau hauv 1.0-1.8% hlau (Fe) cov ntsiab lus. Iron works synergistically with nickel to catalyze the formation of an exceptionally dense, tough, and self-healing complex oxide film on the alloy's surface (primarily Cu₂O, embedded with NiO and Fe₂O₃). Qhov no sawv cev rau "kev txhim kho caj ces" kev daws teeb meem, qhov twg cov khoom siv hauv cov qauv tsim tau tsim kom muaj kev vam meej hauv cov cheeb tsam hnyav.
SB111 C44300 tooj liab vs. C70600 tooj liab
| Performance Dimension | SIB 111 C44300 | SIB 111 C70600 | Txhais qhov txawv |
|---|---|---|---|
| Thermal conductivity (W / m · K) | ~109 | ~50 | C44300's heat transfer efficiency yog ntau tshaj ob npaug. Rau cov dej num zoo tib yam thermal, siv C70600 yuav tsum muaj kwv yees li 2.2 npaug ntawm qhov chaw tshav kub hloov chaw, cuam tshuam ncaj qha rau cov khoom siv hluav taws xob loj thiab tus nqi. |
| Tso cai Flow Velocity (Clean Seawater) | Tsawg dua lossis sib npaug li 2.4 m / s | Ntau tshaj lossis sib npaug li 4.0 m / s | C70600's tolerable tshaj tawm yog tshaj 1.7 npaug tshaj C44300's. Qhov no tso cai rau siab dua - qauv tsim, txo qhov fouling, thiab muab qhov kev nyab xeeb loj dua rau cov twj tso kua mis. |
| Kev tiv thaiv rau Impingement Attack | pluag. Siab - nrawm nrawm tuaj yeem yooj yim tshem tawm nws cov zaj duab xis saum npoo, ua rau lub zos pitting / yaig sai sai. | Zoo heev. Lub siab -hlau- cov ntsiab lus oxide zaj duab xis yog qhov zoo tshaj plaws tenacious, tiv taus yaig los ntawm cov xuab zeb- cov dej. | Qhov no yog qhov tseem ceeb ntawm kev txiav txim siab lub neej ntawm cov tubing inlets, U-khoov, thiab lwm qhov chaw muaj kev kub ntxhov. C70600 muaj kev ntseeg siab zoo dua. |
| Tolerance rau Sulfide Contamination | Neeg pluag heev. Cov lej ntawm H₂S tuaj yeem rhuav tshem nws cov yeeb yaj kiab tiv thaiv, ua rau tus nqi corrosion rau skyrocket. | Zoo. Nws cov yeeb yaj kiab tiv thaiv tseem nyob ruaj khov nyob rau hauv ib puag ncig sulfide. | Cov cuab yeej no yog qhov tseem ceeb rau cov kab ke nrog cov dej qias neeg (xws li, chaw nres nkoj, estuaries) lossis qhov twg sulfate - txo cov kab mob. |
| Galvanic Potential hauv Seawater | Ntau Active (Anodic). | Ntau Noble (Cathodic). | Lawv yuav tsum tsis txhob muab sib xyaw rau hauv tib lub tsev. Yog tias muaj hluav taws xob sib txuas, C44300 yuav corrode nyiam los tiv thaiv C70600. |
| Tus nqi kwv yees (ib kg) | Baseline (qis dua) | ~1.5x - 2.0x C44300 | Tsav feem ntau los ntawm tus nqi npib tsib xee. C44300 yeej ntawm kev siv peev thawj zaug. |
| Hom Kev Ua Haujlwm Tseem Ceeb | Dezincification (yog tias arsenic depleted), impingement nres, sulfide -induced ceev corrosion. | General phab ntsa thinning (hloov heev), pitting nyob rau hauv deposits (yog hais tias dej yog stagnant / fouled). | C44300 tsis ua haujlwm feem ntau yog tam sim ntawd thiab hauv zos. C70600 degradation feem ntau qeeb thiab kwv yees. |
Kuv yuav xaiv li cas ntawm C44300 thiab C70600?
Cov Case rau C44300: Xaiv nws thaum cov dej chemistry tau lees paub tias yog qhov zoo, huv si, thiab qis - nrawm, thiab txo qis kev nqis peev thawj zaug yog lub hom phiaj tseem ceeb. Nws yog qhov siv tau "tus nqi tus kws ua haujlwm xaiv" rau kev tswj hwm, qis- cov ntawv thov pheej hmoo lossis rov ua cov tshuab uas twb muaj lawm nrog cov pov thawj keeb kwm ntawm kev vam meej nrog Admiralty tooj dag.
Case rau C70600: Xaiv nws thaum muaj kev ntseeg siab ua haujlwm, txo kev txij nkawm, thiab lub neej ua haujlwm ntev yog qhov tseem ceeb. Nws cov nqi pib siab dua yog amortized ntev dua, kev kwv yees lub neej ntev dua nrog kev pheej hmoo ntawm kev puas tsuaj loj. Nws yog tus qauv defacto rau tshiab - tsim, tsim, tseem ceeb, lossis hnyav- kev pabcuam hauv dej hiav txwv (cov nkoj nkoj, cov chaw tawm ntug dej hiav txwv, cov nroj tsuag desalination) uas cov dej tsis tuaj yeem tswj tau zoo.
