C44300/C70600 Quick-Table Sib piv
| Feature | SB111 C44300 (Admiralty tooj dag) | SB111 C70600 (90-10 Cupronickel) |
|---|---|---|
| Lub Npe | Admiralty Brass, Arsenical Admiralty | 90-10 Cupronickel, Cunifer 10® |
| Alloy Tsev Neeg | Inhibited Tin Brass (Cu-Zn-Sn + As) | Cupronickel (Cu-Ni-Fe) |
| Kev sib xyaw ua ke | Ua haujlwm siab: 70-73% Zn: 28-29% Cov ntsiab lus: 0.9-1.2% Raws li (Arsenic): 0.02-0.10% (Inhibitor) |
Cu: 86.5% min Tsis muaj: 9.0-11.0% Fe: 1.0-1.8% Mn: 0.3-1.0% Zn: 1.0% max (tsis muaj paug) |
| Ntsiab Metallurgical Additive | Arsenic (As) - Qhov tseem ceeb rau inhibiting dezincification. | Nickel (Ni) + Hlau (Fe) - Ni muab cov tshuaj tiv thaiv kom muaj zog thiab kev tiv thaiv corrosion tseem ceeb; Fe txhim khu kev tiv thaiv rau impingement / yaig corrosion. |
| Primary Corrosion Resistance Mechanism | Tsim kom muaj kev tiv thaiv, adherent zaj duab xis. Arsenic inhibits kev xaiv leaching ntawm zinc (dezincification). | Tsim kom muaj ib qho nyuaj, nyuaj, thiab ua tau zoo tiv thaiv txheej txheej feem ntau ntawm cuprous oxide (Cu₂O), stabilized thiab ntxiv dag zog los ntawm npib tsib xee thiab hlau oxides. Cov txheej no yog tus kheej - kho. |
| Lub zog & Mechanical Properties | Lub zog qis. Hom Tensile: ~ 330 MPa (48 ksi) Yam Yield: ~ 130 MPa (19 ksi) Ntau ductile, softer. |
Siab zog. Hom Tensile: ~ 290-380 MPa (42-55 ksi) Hom Yield: ~ 125-200 MPa (18-29 ksi) Muaj zog, ntau resistant rau creep thiab sag. |
| Thermal conductivity | ~ 109 W / m·K (High) - Qhov zoo rau kev hloov pauv cua sov. | ~50 W/m·K (Moderate) – Kwv yees li ib nrab ntawm Admiralty. Xav tau ntau qhov chaw saum npoo rau qhov sib npaug sib npaug. |
| Qhov siab tshaj plaws tso dej tshaj tawm | ~ 2.1 m / s (7 ft / s) - Muaj kev cuam tshuam rau kev yaig-corrosion ntawm qhov nrawm dua. | ~ 3.6-4.6 m / s (12-15 ft / s) - Kev tiv thaiv zoo tshaj plaws rau kev tawm tsam vim yog txheej txheej tiv thaiv tawv. |
| Resistance rau tej kev hem thawj | Tsis zoo: Sulfide pollution, ammonia, siab -ceev/suspended solids. Zoo: huv si, ntws dej hiav txwv. |
Zoo heev: High- dej ceev, xuab zeb / silt yaig, sulfide muaj kuab paug (tseem ceeb zoo dua tooj dag). Zoo: Ammoniacal ib puag ncig (zoo dua tooj dag). |
| Biofouling Resistance | Nruab nrab. Tooj liab ions muab qee cov nyhuv biocidal, tab sis biofilm tseem tuaj yeem tsim. | Superior. Cov khoom lag luam corrosion tsis tshua muaj siab txais tos rau cov kab mob marine. Cov ntsiab lus nickel tseem tiv thaiv biofouling. |
| Galvanic txoj hauj lwm | Ntau anodic (active) txheeb ze rau Cupronickel. Yuav corrode nyiam yog tias ua ke. | Ntau cathodic (noble) txheeb ze rau Admiralty Brass. |
| Tus nqi (khoom siv) | qis. Muaj cov zinc uas pheej yig dua ua lub ntsiab alloying. | Siab dua. Muaj npib tsib xee kim (~ 20-30% tus nqi hwm tshaj Admiralty, nyob ntawm Ni khw). |
| Tej kev siv | - Fais fab nroj tsuag condensers nrog huv, tsis tshua muaj - dej txias tshaj (tshiab, brackish, los yog dej hiav txwv huv). - Tsawg- kev xaiv tus nqi rau cov kev pabcuam tsawg dua. |
- Tus qauv rau cov tshuab dej hiav txwv niaj hnub no: shipboard condensers, offshore platform heat exchangers, desalination nroj tsuag. - Cov kab ke nrog cov dej nrawm nrawm, dej xuab zeb, lossis dej tsis sib xws. |
Thaum twg siv Qhov twg?
Xaiv SB111 C44300 (Admiralty Brass) thaum:
Cov dej txias yog huv si, qis - nrawm (<2.1 m/s), and sulfide-free (e.g., many freshwater-cooled power plants, some clean estuary sources).
Tus nqi pib yog thawj tus neeg tsav tsheb thiab cov dej num muaj keeb kwm pov thawj tias yog qhov zoo.
Nws yog ib qho kev hloov hauv ib qho system uas twb muaj lawm uas yog tsim los rau Admiralty.
Xaiv SB111 C70600 (90-10 Cupronickel) thaum:
Qhov nruab nrab cua txias yog dej hiav txwv puv lossis dej brackish.
Cov dej nrawm nrawm yog xav tau lossis ua tau.
Cov dej muaj cov khib nyiab tshem tawm (xuab zeb, silt) los yog muaj kuab paug sulfide.
Tsawg biofouling thiab siab tshaj plaws ntev - lub sij hawm cia siab rau yog ib qho tseem ceeb (xws li, naval nkoj, offshore platforms, desalination nroj tsuag).
Lub neej- tus nqi voj voog (tsis yog tus nqi pib xwb) yog suav tias yog- nws lub neej ua haujlwm ntev dua feem ntau ua pov thawj tus nqi siab dua.
C44300 yog tus nqi- tus kws tshaj lij ua haujlwm tau zoo rau kev huv, qis- kev pabcuam kev ntxhov siab. C70600 yog qhov muaj zog, tag nrho -ib puag ncig tus yeej rau kev thov cov ntawv thov dej hiav txwv, qhov twg nws tus nqi hwm yuav tau txais txiaj ntsig zoo thiab kev ntseeg tau zoo. SB111 specification ua kom ob qho tib si ua tau raws li cov qauv nruj thiab qhov loj me rau cov tubing siab.
