Steel Pipes

"We were able to use less material and less labor to install a system that would give us the equivalent
of 3/8-inch steel on the outside of this pipe. We were thrilled when using HJ3’s materials."

Oil Refinery Cooling Repair Tower

“We fixed these 12 riser pipes 15 years ago with HJ3’s material, and the pipes have not leaked or caused us any problems ever since” – J. Kirby, Plant Engineer

Twelve of the steel riser pipes in the refineries cooling tower showed severe corrosion and leaks.  Once excavated, the leaks were exposed
and created massive flooding and dangerous terrain for plan operations.

Typical Leaking Riser Pipe

Riser Pipe Sealed and Strenghtened with CarbonSeal

The steel riser pipes were excavated to a depth of 10 feet and the steel was abrasive blasted and cleaned to white metal.
Leaks were patched with HJ3’s epoxy putty. Two Layers of CarbonSeal were wrapped around the circumference
of the steel pipe spanning 8 feet below grade and 5 feet above grade. Twelve Riser pipes were completed in 10 days,
saving the client considerable down time costs. Total projects savings were 92% of replacement.
