Hastelloy Heat Exchangers Removal for Water and Wastewater Facilities

Hastelloy Heat Exchangers removal context in Water and Wastewater

Hastelloy heat exchangers are specialized thermal management units constructed from nickel-molybdenum-chromium alloys, such as Hastelloy C-276, C-22, B-2, and Hastelloy-N. Installed removal from a water or wastewater facility also depends on the actual process, residual service, isolation status, surrounding systems, and facility access described in the water and wastewater 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 water and wastewater system. Unknown conditions should be identified as unknown.

• Maintenance logs showing chemical descaling history.
• Records of struvite and vivianite removal.
• Evidence of routine mechanical cleaning.
• Assess weight and dimensions for heavy lift and transport planning, especially for thick-walled high-pressure units.
• Plan for isolation and safe draining of hazardous or corrosive residual fluids (e.g., molten salts, concentrated acids).
• Ensure proper handling to prevent damage to specialized alloy surfaces or tube bundles.

Dismantling, loading, and freight planning

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

• Assess weight and dimensions for heavy lift and transport planning, especially for thick-walled high-pressure units.
• Plan for isolation and safe draining of hazardous or corrosive residual fluids (e.g., molten salts, concentrated acids).
• Ensure proper handling to prevent damage to specialized alloy surfaces or tube bundles.
• Coordinate with specialized rigging and freight services for heavy industrial equipment.
• Requires proper isolation from biological and chemical processes.
• Residual sludge and scaling must be addressed.
• Specialized lifting equipment needed due to heavy fouling weight.

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.
