Industry: Petrochemical
Description of Equipment: 3 Transfer Line Exchanger (TLE) Cones
Problem: Originally specified conventional refractory lining did not deliver expected service
life. Refractory became coke-impregnated and vitrified. Material failed in operation shortly
after one year of service. Customer was looking for a refractory product that resisted coke
penetration and provided much longer life.
Solution: Customer contacted Stellar looking for a Thermbond product that might provide
extended refractory service life. Speed of turnaround was also a high priority. A Thermbond
refractory lining was the ideal solution due to the ability to resist coke penetration, fast
installation, and no heat cure required to put back into service.

Product Being Replaced: Conventional monolithic refractory
Production's Required Turnaround Time: ASAP - unit was offline
Actual Turnaround Time Using Thermbond: 2 days
Products Applied: Thermbond Formula 6-L
Method of Installation: Cast-vibrated
Equipment Used: Internal plastic-coated steel mandrel, form vibrators, hobart mixer,
miscellaneous tools.
Scope of Work: Mixed and cast continuous monolithic pour of Thermbond Formula 6-L.
Internal mandrel was vibrated by external clamp-on vibrators. Three cones were lined in
one day. Total material required per cone was 64 units.
Installation Date: September 2006
Follow Up: March 2007, no problems. Plant continues to use Thermbond to replace conventional monolithics.
