Crack and hole repair on casings and equipment
Welding on pressure separators and code-stamped vessels triggers re-stamping, stress relief and thermal distortion that can cost more than the defect.
What is failing
A crack or through-wall hole in a code-stamped vessel or pressure separator is rarely a simple weld. Welding triggers re-stamping, post-weld stress relief, and thermal distortion that can run higher than the defect that started it. The vessel stays down through the whole inspection and qualification cycle.
How AAS does it
AAS cold-bonds the structural repair onto prepared metal and machines it back to the original profile, with no hot work and no heat-affected zone. The crew works in our shop or in the field using structural repair composites such as Belzona 1111 and 1121. The result qualifies as a non-welded repair under the relevant inspection codes, including the composite repair provisions of ASME PCC-2.
Typically applied with Belzona 1111, Belzona 1121, matched to the service conditions.
The defect is sealed and rebuilt without re-stamping or stress relief. The vessel returns to service faster and the operator avoids a welded-repair qualification cycle.
How AAS delivers it
AAS performs Crack and hole repair on casings and equipment work for Oil & Gas, Petrochemical & Chemical, and Manufacturing operations across Baton Rouge and Louisiana, cold-applied and in place wherever possible, on your turnaround schedule. Crews are factory-trained Belzona applicators, the repair system is matched to the service conditions it will see, and urgent failures are covered by 24-hour on-call response. The result is a permanent, engineered repair that returns the asset to service without the cost or downtime of full replacement.
