Hastelloy Heat Exchangers Removal for Oil Refining Facilities

Hastelloy Heat Exchangers removal context in Oil Refining

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

• Check equipment data plates for ASME, TEMA, or API specifications.
• Verify material of construction for tubes, shell, and heads (e.g., carbon steel, stainless steel, alloys).
• Inspect for signs of external corrosion, pitting, or weld degradation.
• 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.
• Ensure complete isolation and blinding from process lines before removal.
• Verify that the unit has been properly drained, purged, and flushed of all residual hydrocarbons and hazardous chemicals.
• Anticipate the need for heavy lifting equipment, such as cranes, due to the substantial weight of industrial heat exchangers.

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.
