Hot Spot Repair

Prevent unscheduled and expensive shutdowns

Insulcon offers the unique service of Hot Spot Repair. For over 30 years already we have completed many Hot Spot Repair jobs on process heaters, boilers, reformers, etc. while they were still operating! Guarantee a safe working environment for the people and save money of an expensive shutdown by using this system to repair your hot spots. This unique system consists of a special developed pumping mix, a controlled pump system and of course an experienced stand-by group of Insulcon engineers.

Continuous operation (24/7) of most furnaces results in deterioration of the hard refractory, hot face lining and will damage the backup insulation. Cracking and erosion of moulded parts and linings will expose the backup insulation to high furnace operation temperatures. As a result, the backup insulation will overheat and hot spots will occur, resulting in a shut down of the heater/furnace and a cooling down period before actual inspection and refractory repair will be possible.

The Insulcon Hot Spot Repair system (HSR) will eliminate all those problems. In close co-operation with Harm Meijer BV, specially trained engineers will act immediately.

1. While the system remains functional, holes are drilled in the casting plate. After this, couplings are welded onto it.

2. Specially developed injection moulds are now being injected through the mounted couplings.

3. As soon as injection mould is injected, the whole area of the hot spot cools down immediately.

4. Changes of pressure combined with over 30 years of experience indicate when the gap is completely filled.

5. The drilled holes/couplings are closed. The repaired spot usually remains colder than the rest of the surrounding area.
