Suitable for use for large dimensions or pre­existing pipeline flanges, higher pressures, and high technical tightness require­ ments. Due to the inferior heat radiation in the attachment area, operating temperatures should not surpass 450 to 500 °C. With the use of larger flanges, the expansion joint can be placed further outward [away from the flow of the medium], and additionally protected by another insulation or retrofitted insulation. This will allow operating temperatures between 600 and 650 °C.
