Applications of Hot-tek Online Repair

Hot Tube Stabilization

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.
