Hastelloy Heat Exchangers Removal for Chemical Processing Facilities

Hastelloy Heat Exchangers removal context in Chemical Processing

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

• Identify material of construction (e.g., carbon steel, stainless steel, titanium, high-alloy).
• Check for specialized designs like low hold-up volume or specific plate angles.
• Review NDE (Non-Destructive Examination) records such as Eddy Current Testing (ECT) or IRIS.
• 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 rigorous isolation and purging of hazardous or corrosive media (e.g., acids, amines, hydrogen sulfide).
• Must account for potential residual chemical exposure during dismantling.
• Proper neutralization and flushing of chemical cleaning agents is required prior to transport.

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.
