Tank Repair
 HJ3’s
system of carbon fiber composites can be used to repair
large steel and concrete tanks used for storage or processing
of aggressive chemicals. These high strength composite
systems are capable of restoring the tensile strength
of corroded steel and concrete tank walls that have deteriorated
from exposure to aggressive acidic or alkaline chemicals. The
HJ3 system also provides additional chemical protection
and has been tested to withstand chemicals ranging from
pH 1 to pH 13 in over 20,000 hours of continuous exposures.

 Pipe Repair
Corrosion of steel reduces pipe strength and service life. Traditionally, owners are forced to replace the damaged pipe, requiring extensive downtime, the use of heavy equipment and excavation.
HJ3 Composite Systems structurally repair and restore
damaged pipe. Installed internally or externally, HJ3
Composite Systems return the pipe to its original design
value without costly downtime, heavy equipment or excavation.

Support Structures
 Whether
columns, beams, or walls, HJ3’s high strength composite
systems are the perfect cost-effective repair and
strengthening system for plant support structures. These
composite systems can be used with appropriate top coats
(such as fireproofing) to retain plant standards. Typical
applications include corroded columns, piping support beams,
secondary containment areas and control rooms. (back
