HardTape use galvanized steel cord knitted tape to repair one concrete coker storage structure

Refineries and their structures are in an environment that is highly susceptible to deterioration. The processes for operation are often aggressive and ongoing, leading to structure deterioration.

A coker factory  had signs of deterioration after years of service producing and handling petroleum coke. The owner chose to implement an Investigate-Design-Build (IDB) approach for a seamless repair process that would allow the project to be completed within budget during an upcoming turnaround.

 HardTape performed a condition assessment to determine the level of deterioration and the best course of action for repairs.

The ultra high-pressure (450ksi) water demolition was used to facilitate concrete removal, surface preparation, and cleaning of the reinforcing steel. Performed by HardTape, this method reduced this portion of the project from nearly 20 shifts with 20 over employees to only 6 shifts with only a few workers. This was a significant reduction in both time and safety exposure.

Following demolition of the existing concrete, HardTape team performed concrete repairs throughout the coker structure, pit and maze,by two layers of  600g/m2 light density hot-dipped galvanized steel cord knitted hard tape combined with three layers of specialized cement mortar.

The project was successful from all aspects and the Owner was thrilled to have less manhours as well as an accelerated project schedule. The coker was turned back over early, under original budget with zero safety incidents.
