Thermbond Refractories
Transfer Line Exchanger Cone Refractory Replacement- Cast
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.
Internal collapsible mandrel
assembled ready for insert inside
TLE cone.
Thermbond Formula 6-L during
pouring of area between mandrel
and internal surface of TLE cone.
Completed pour of Thermbond after
mandrel removal. Note cosmetic
imperfections caused by plastic film
covering used on mandrel surface.
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.
