Spiral Heat Exchangers Removal for Chemical Processing Facilities

Spiral Heat Exchangers removal context in Chemical Processing

A spiral heat exchanger (SHE) is a highly efficient, compact heat transfer device constructed by rolling two parallel metal plates around a central core to form two separate, concentric spiral channels. 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.
• Ensure complete isolation, depressurization, and draining of both hot and cold fluid circuits before disconnection.
• residual viscous fluids, slurries, or solids may remain trapped in the spiral channels and require specialized flushing or handling.
• rig securely using manufacturer-designated lifting lugs or structural frame points, accounting for the heavy, dense nature of the coiled metal construction.

Dismantling, loading, and freight planning

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

• Ensure complete isolation, depressurization, and draining of both hot and cold fluid circuits before disconnection.
• residual viscous fluids, slurries, or solids may remain trapped in the spiral channels and require specialized flushing or handling.
• rig securely using manufacturer-designated lifting lugs or structural frame points, accounting for the heavy, dense nature of the coiled metal construction.
• protect flanged connections and machined cover sealing surfaces from mechanical damage during transit.
• 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.
