The fabric expansion joints shown above are fabricated with a three layer fabric belt. The three layers consist of an inner layer of silica cloth, a middle layer of mineral wool and an outer layer of PTFE/coated fiber glass. The frame includes an insulation blanket of mineral wool and stainless steel wire mesh. The frame and liner are fabricated from 3/8″ thick 304 stainless steel and each expansion joint’s frame and liner welds were dye-penetrant tested before shipping.
