Copper-Nickel Heat Exchangers Removal for Pharmaceutical Manufacturing Facilities

Copper-Nickel Heat Exchangers removal context in Pharmaceutical Manufacturing

Copper-nickel alloys, particularly CuNi 90/10 (UNS C70600), are extensively used for heat exchangers in shipbuilding, offshore, and desalination applications due to their excellent resistance to uniform corrosion, localized corrosion in chlorinated seawater, and biofouling. Installed removal from a pharmaceutical facility also depends on the actual process, residual service, isolation status, surrounding systems, and facility access described in the pharmaceutical manufacturing evidence record.

The removal plan must be based on the submitted unit and site. This page does not imply a local crew, permit authority, preapproved lift, guaranteed pickup, or unconditional service availability.

Isolation and residual-service record

Before commercial or logistics commitments, document how both exchanger sides were isolated, drained, cleaned, released, and separated from the pharmaceutical manufacturing system. Unknown conditions should be identified as unknown.

• Look for ASME-BPE certification stamps or documentation.
• Check for double tubesheet configurations (shell-and-tube) or welded plate designs.
• Inspect surface finishes (often electropolished to Ra <= 0.4 microns).
• Install strainers to prevent introduction of solid matter.
• Avoid stagnant conditions in seawater with suspended particles.
• Flush with clean seawater and keep dry during shutdown.

Dismantling, loading, and freight planning

The physical plan should connect the copper-nickel heat exchangers configuration to verified dimensions, weight, lifting points, access, staging, carrier profile, and responsibility boundaries.

• Install strainers to prevent introduction of solid matter.
• Avoid stagnant conditions in seawater with suspended particles.
• Flush with clean seawater and keep dry during shutdown.
• Maintain minimum flow rate of 1 m/s in seawater with suspended matter.
• Require specialized handling to protect high-purity surface finishes (e.g., Ra <= 0.4 microns) from scratches or contamination during removal.
• Must be carefully drained, as surface tension in highly polished tubes can retain fluids, sometimes requiring blown air.
• Double tubesheet designs and sanitary fittings (e.g., Tri-Clamps) must be protected from mechanical damage.

Written scope before work

Dismantling, rigging, loading, freight, scheduling, and payment are conditional project functions. A written scope must identify responsible parties, safety release, access rules, exclusions, equipment boundaries, carrier requirements, and commercial terms before performance.
