Surface Preparation for Bonded Pipeline Repairs: the 2021 Study
A peer-reviewed 2021 study evaluated surface treatments for repairing through-wall corrosion damage in metallic pipes with adhesively bonded plates — where surface preparation quality determines repair integrity.
Bonded and composite repairs let operators fix corrosion damage without cutting out pipe — but the bond is only as good as the prepared surface. This page summarizes the peer-reviewed 2021 study on surface treatments for through-wall corrosion repairs with bonded plates.

What does it cover?
The study evaluates alternative surface treatments for metallic pipes repaired with adhesively bonded plates, comparing how each prepared surface performs in the bonded repair — directly relevant to composite wrap and plate-bonding repair systems used on live pipelines.
Why does it matter?
Composite repair systems are increasingly specified precisely where blasting is hardest: live lines, confined rights-of-way, in-service assets. Preparation method choice is then part of the repair design, not just execution. See pipeline applications and the field-joint preparation guide.
