Heat Exchanger Tubesheet Copper Alloy Steel Tubesheet ASTM B171 C46400 PT Available
Product Overview
This heat exchanger tubesheet is manufactured from ASTM B171 C46400 (Naval Brass), a high-strength copper-zinc-tin alloy renowned for its exceptional resistance to corrosion and biofouling in seawater and brackish water environments. Designed as a critical component for shell-and-tube heat exchangers in marine, offshore, and coastal applications, it provides reliable, long-term service where other materials may fail. Each tubesheet is precision-machined and is available with Liquid Penetrant Testing (PT) to ensure the integrity of all machined surfaces prior to installation.
Material Specification & Compliance
This product is in full compliance with ASTM B171 Standard Specification for Copper-Alloy Plate and Sheet for Pressure Vessels, Condensers, and Heat Exchangers.
Material Standard: ASTM B171, UNS C46400 (Naval Brass).
Common Forms: Plate, machined to finished tubesheet dimensions.
Non-Destructive Test (Optional): Liquid Penetrant Testing (PT) per ASTM E165 / ASME SE-165.
Machining: Precision-faced, drilled, and grooved per client TEMA layouts.
Certification: MTR (Mandatory), PT Report (Upon request).
Key Features & Advantages
Superior Seawater Corrosion Resistance: C46400 Naval Brass offers outstanding resistance to dezincification, impingement attack, and stress corrosion cracking in saltwater, making it the historic material of choice for marine condensers and coolers.
Inherent Anti-Biofouling Properties: The copper ions released from the surface inhibit the growth of marine organisms (such as barnacles and algae), reducing maintenance needs and preserving heat transfer efficiency over time.
Verified Surface Integrity: Optional Liquid Penetrant Testing (PT) provides documented verification that critical sealing faces, tube holes, and pass partition grooves are free from surface defects, ensuring a leak-free foundation.
Excellent Fabricability: This alloy combines good machinability with high ductility, allowing for precision drilling and grooving to meet tight TEMA tolerances.
Full Material Traceability: Supplied with complete Mill Test Reports (MTRs) certifying compliance with ASTM B171 for chemistry and mechanical properties. Optional PT reports are provided upon request.
Typical Applications
Marine & Shipbuilding: Main and auxiliary seawater coolers, condensers, lubricating oil coolers.
Offshore Oil & Gas: Seawater cooling systems on platforms and FPSOs.
Power & Desalination: Coastal power plant condensers, Multi-Stage Flash (MSF) and Multi-Effect Distillation (MED) evaporator tubesheets.
Chemical Processing: Handling specific corrosive process streams where copper alloys are specified.
