Refractory lined expansion joint Refractory lined expansion joint A Refractory lined expansion joint is an assembly used in a pipe line to allow it to expand and contract as climate conditions move from hot to cold and helps to ensure that the system remains functional. The refractory-lining can be vibra cast insulation with anchors, abrasion resistant refractory in hex mesh, gunned insulating refractory, or poured insulating refractory. Refractory lined expansion joints can be hinged, in-line pressure balanced, gimbal, tied-universal depending on the temperature, pressure, movement and flow media conditions. Refractory lined Expansion joints are used in extremely high temperature and high pressure applications and
