Welded-Plate Heat Exchangers Removal for Oil Refining Facilities

Welded-Plate Heat Exchangers removal context in Oil Refining

Welded-plate heat exchangers consist of corrugated metal plates that are welded together rather than sealed with gaskets. 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.
• Ensure the system is fully depressurized and drained before removal.
• The compact size may simplify access and lifting compared to shell-and-tube units.
• Protect welded seams from impact during handling and transport.

Dismantling, loading, and freight planning

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

• Ensure the system is fully depressurized and drained before removal.
• The compact size may simplify access and lifting compared to shell-and-tube units.
• Protect welded seams from impact during handling and transport.
• Verify weight and dimensions for proper lifting equipment selection.
• 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.
