IGS’s Hot-tek services in Malaysia facilitate maintenance, inspection and cleaning of the fired heater while it is in operation. Holding multiple patents on the approach, methods, and tools used to carry out these services.
In the last four decades, Hot-tek has developed and introduced a wide range of online services (while the heater is operating), targeted at high-temperature production furnaces and heaters. Each project is approached with the utmost safety in mind, ensuring that none of our people or equipment are compromised during the execution of the Hot-tek Services. Evaluation and engineering phases of each Hot-tek project determine the best operational approach and parameters will be set to achieve an optimal outcome with no downtime.
Hot-tek has developed an on-line repair service to stabilize the process tubes while the heater is still in full operation. The stabilizer can either be supplied by the customer or fabricated by Hot-tek.
The typical metallurgy of tube supports is HK40 (or similar). More frequently than not, this material can be difficult to source in a short period of time. If HK40 is available, it will be utilized; otherwise 310SS is the next best candidate for the stabilizer material.
Failed tube support
Stabilizer inserted, welded in place
Utilizing proprietary procedures, Hot-tek will make a penetration in the vicinity of the failed tube support, insert the stabilizer, then weld the stabilizer in place, replacing the refractory and the external steel shell in the repair area.
