Distinct from conventional expansion joints, the Bachmann GTEJ range incorporates unique design features to combat the thermal extremes faced while operating at high exhaust temperatures. All welded components are of same material with identical thermal growth coefficients designed for typical operating temperatures of 450°C to 680°C to eliminate the potential for damaging stress.Stainless steel liners are of a bolted construction with slotted holes to allow full thermal differential expansion.
Hot gas flow path to belt element is prevented by a pinned Dome Seal arrangement, which follows the frame’s thermal movement and allows the insulating material to fully expand after compression eliminating ‘hot spots’ on the fabric belt. ‘Channel clamp fixing’ system of belts enables to prevent gas leakage and it can handle both lateral and axial movements with very low spring force. A totally integral design requiring no cladding or welding at site.
