ASME SB171 C46400 Naval Brass Tubesheet

Forged or Rolled Plate | Corrosion-Resistant for Marine & Heat Exchanger Applications

Product Overview

This ASME SB171 C46400 tubesheet is manufactured from naval brass, a copper-zinc alloy with tin addition that significantly enhances corrosion resistance in marine and industrial environments. C46400 is widely recognized for its excellent resistance to seawater corrosion, dezincification, and stress corrosion cracking, making it ideal for tubesheets in heat exchangers and condensers operating in aggressive water-based services.

Material Specifications & Manufacturing Options

Attribute	Specification / Option	Key Details
Material Standard	ASME SB171 / C46400 (Naval Brass)	Copper-zinc-tin alloy offering superior corrosion resistance, particularly in seawater and brackish water.
Manufacturing Form	Forged or Rolled Plate	Forged provides enhanced mechanical properties; rolled plate is suitable for standard thickness requirements.
Dimensions	Custom per customer drawing	Thickness, diameter, and bolt circle machined to match existing heat exchanger or condenser.
Drilling Pattern	Triangular, Square, or Custom	Optimized for tube layout, flow distribution, and structural integrity.
Surface Finish	Machined, Grooved for Tube Expansion	Precision machining ensures accurate tube hole diameters and groove profiles for secure tube-to-tubesheet joints.

Associated Components & Parts

Component	Typical Material	Notes
Heat Exchanger Tubes	C70600 (90/10 Cu-Ni), C71500 (70/30 Cu-Ni), or Admiralty Brass	Tube material should be compatible with C46400 tubesheet for galvanic corrosion control.
Shell or Channel	Carbon Steel (coated), Stainless Steel, or Copper Alloy	The housing that the tubesheet seals against.
Gaskets	Compressed Fiber, PTFE, or Metal Jacketed	Provides sealing between tubesheet and shell/channel flange.
Fasteners (Bolts/Nuts)	Stainless Steel (304/316) or Silicon Bronze	Selected to avoid galvanic corrosion with naval brass.
Baffles	C46400, C70600, or Coated Carbon Steel	Supports tube bundle and directs shell-side flow.
