HJ3
Composite Technologies offers the most comprehensive line of strengthening
products in the world for fortifying and protecting structures against
earthquakes, blasts, and environmental damage.
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. >> More Details
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.
