Flat Patch Tank Repair Kit
The Flat Patch Tank Repair Kit is a carbon-epoxy composite repair system designed for active sealing applications where localized repair is needed or full pipe wraps are impractical. The system combines a preformed carbon sheet with advanced adhesives to enable working pressures up to 1,000 PSI (70 kg/cm2) and operating temperatures up to 350ºF (177ºC).
The Flat Patch Tank Repair Kit consists of a preformed carbon composite sheet and two advanced epoxy adhesives to provide superior leak sealing on flat surfaces. This novel approach enables the sealing of actively leaking defects, the localized repair of tank surfaces, and the ability to bond through oil contamination. The repair kit is recommended for pressure applications up to 1,000 psi (70 kg/cm2) with a built in 4:1 safety margin. Return to service at pressure may be accomplished in ~2 hours for temperatures above 75°F.

InduMar Client
"Thanks to InduMar's Flat Patch, we were able to repair multiple tanks that had been out of commission, and now they are back in service."
Plant Equipment & Services
"STOP IT® conformability makes it extremely effective for repairing leaks at joints, crosses, tees or any other location. The knitted fiberglass allows it to be maneuvered as it is being applied. The mechanics involved in the tight wrapping of the product allows STOP IT® to bond more effectively. These adhesive properties allow it to form a successful repair on hard-to-stick pipe surfaces. STOP IT® heavy resin load allows it to finish out to create a strong, homogenous repair."

"I work tour maintenance. We do emergency maintenance. We have to get things back up and running. Works great on emergency repairs and can be put back into service until shut down to make permanent repairs later on. Thank you!"
