The Fiberwall® family of anchoring hardware and accessory components provides an array of attachment options to cover a broad range of lining system designs and application requirements.
When hot face temperatures exceed 1093°C (2000°F) but are below 1149°C (2100°F), the ceramic cuplock retainer can be employed to extend the recommended operating temperature of the 601 Inconel stud to 1149°C (2100°F). The alloy washer is not required when the cuplock is used to retain the insulation lining.
The stud length dimension, when using a 2” cuplock retainer, is determined by subtracting 1” from the applicable lining thickness. To be effective, the Cuplocks inner core must be filled with LDS moldable. This can be done either before or after engaging the cuplock to the stud’s tip. The 1” cuplock is used primarily in layered lining over refractory (L.O.R.) installations where lining thickness is usually 2” or less, corrosive elements are present in the fuel, or when the hot face temperature is below 1121°C (2050°F). Typically, the 1” cuplock is used in conjunction with barbed 601 Inconel studs in L.O.R. Applications. The “barb” of a barbed stud is configured so that it will easily enter within, but will lock securely to, predrilled holes in the refractory surface. LDS Moldable® is employed as a filler to plug the Cuplocks 1” deep core and, as in the 2” cuplock, is carried over to the face of the cuplock to effectively seal around the core’s perimeter edge.
