A coke pit in a refinery’s delayed coking unit had shown signs of deterioration on the pit walls and its integrated maze structure. In addition to corrosion due to chemicals, the walls were cracking and deteriorating due to the impact of front end loaders.
HardTape was selected to perform repairs in the pit and maze structure. The concrete walls were repaired with layers of HardTape proprietary material of galvanized steel cord knitted tape combined with specialized mortar system, which dramatically improves the long-term durability and impact resistance of the walls.Custom designed protective steel Glancing Plates were then installed to act as a barrier from topside crane impact.
Repairs were made during scheduled turnarounds. The West wall was completed in 14 days and the East wall was completed in 21 days.
