Case study
Large-diameter repair with no time for chemical bonding
- Application
- marines
- Pipe Type (material + DN/OD)
- GRP — DN2800
- Pain/Context
- Minimum intervention time; chemical bonding not feasible
- Sector
- Hydropower / Penstocks
- Country
- Panama
- Keywords
- repair, GRP, hydropower, alternative to chemical bonding, penstock
In large-diameter penstocks, repair methods based on chemical bonding often require several days of curing, resulting in high service interruption costs. At the Pando hydropower plant in Panama, a DN2800 GRP pipeline operating at 6 bar was repaired in just three hours using REP couplings—avoiding the 15–20 days required by the chemical alternative.
