Product Description

ASME SB171 C46400 Naval Brass Tubesheet | Seawater Corrosion Resistant for Heat Exchanger Condenser

 

ASME SB171 C46400 tubesheets are core pressure-bearing components in shell-and-tube heat exchangers, condensers, and pressure vessels, used to secure and seal the tube bundle and withstand the pressure difference between the shell and tube sides.
This product is manufactured according to ASME SB171 standards and is made of UNS C46400 naval brass, a copper-zinc-tin ternary alloy. C46400 is widely used in marine heat exchangers, power plant condensers, seawater desalination equipment, and other applications with stringent corrosion resistance requirements due to its excellent performance in seawater and industrial corrosive environments.
ASME SB171 C46400 tubesheets are copper alloy tubesheet solutions for marine engineering, coastal power plants, and chemical industries operating in conditions requiring long-term stable operation with seawater/brackish water media at medium to low pressure.

When to Choose ASME SB171 C46400 Tube Sheets?
  • Foperating temperatures ≤ 260°C and low to medium pressures—C46400 offers stable performance within this range.
  • For projects requiring a balance of corrosion resistance, thermal conductivity, and machinability—C46400 offers a good balance of these three factors.or operating media such as seawater, brackish water, or industrial cooling water—C46400 is a proven choice for these environments.
  • For equipment such as shell-and-tube heat exchangers, condensers, or pressure vessels—ASME compliance is required
