AMPP SP21507-2022, Standard Practice for Sandwich Plate Repair of Steel Structures

Oil and gas industry onshore and offshore drilling, production, storage, and transportation generally experience very corrosive environments. Even though corrosion prevention systems, such as cathodic protection, protective coatings, and liquid/vapor phase inhibitors are usually used for corrosion protection, severe corrosion of the structures is still unavoidable without effective corrosion protection and appropriate corrosion management. The repair of degraded structural members having substantial corrosion damage is critical for maintaining structural integrity for safe and continuous operations.

This standard practice formalizes a methodology of steel sandwich plate repair technology. This methodology uses a new steel plate or prefabricated structural component laid on top of the existing steel plate to be repaired. An elastomer core is used to bond the new plate/component and the existing steel plate to form a steel sandwich plate structure, thereby repairing the existing steel substrate without it being cut and replaced. This method is intended to restore the strength of the damaged structural members, or to reinforce existing structures.
