They’re found on just about every engine and have the function of balancing the different axial and lateral movements of the various connected components within the exhaust system, and from a thermal viewpoint they are often the weak link in an otherwise finely-tuned exhaust line: Compensators. Flexible Sleeves and Bellows. The challenge here can be defined as how to close this loophole in the thermal system by means of high flexibility, effective insulation solutions. Fully-enclosed Metallic Compensator insulations combined with Tmax-SKELTEC can close this loophole, be integrated into the overall system and in addition reduce temperature loss in the Mining equipment application.
