Copper-Nickel Heat Exchangers Removal for Plastics and Polymer Processing Facilities

Copper-Nickel Heat Exchangers removal context in Plastics and Polymer Processing

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 plastics or polymer plant also depends on the actual process, residual service, isolation status, surrounding systems, and facility access described in the plastics and polymer processing 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 plastics and polymer processing system. Unknown conditions should be identified as unknown.

• Verify construction materials (e.g., metallic vs. polymeric components).
• Check for specialized coatings or surface treatments.
• Inspect for signs of fouling, scaling, or thermal degradation.
• 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.
• Account for potential presence of hardened polymer residues or viscous fluids.
• Plan for specialized cleaning or solvent treatments prior to removal.
• Ensure proper handling of potentially heavy or bulky units.

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.
