TIVAR® Capped Elevator Bolts
TIVAR® capped elevator bolts are a “through” bolt attachment fastening system. The unique design aspect of this fastener is the fact the elevator bolt base has a heat sleeved cap of TIVAR® covering the head, which is then countersunk “flush” into the TIVAR® 88 material. The design of this fastener is to intended to provide secure attachment of TIVAR® 88, while minimizing bulk material contact with exposed steel. TIVAR® capped elevator bolts are available for liner thicknesses of ¼” to 2”.
Weld Washers and TIVAR® Plugs
Weld washer attachment fasteners are a ”non-through bolt” attachment system for TIVAR® 88 liners. Weld washer attachment fasteners consist of either a carbon steel or stainless steel embossed washer that is counter sunk into the TIVAR® 88 material, electro welded to the mating substrate and covered with a compression fit plug of TIVAR®. The resulting attachment fastener is surface flush, minimizing the point of contact with bulk materials and provides a smooth finish surface. Weld washers can be used to attach TIVAR® 88 liners in thicknesses of 3/8” to 2”.
Studs and Spanner Nuts
Stud weld attachment fasteners are a fast, secure and efficient way to attach TIVAR® 88 liners. Stud welding is a “non-through bolt” fastening method, in which a thread stud is arc welded to a steel substrate through a counter bored hole in the TIVAR® 88 liner. After the threaded stud is arc welded to the substrate, a steel threaded spanner nut is driven down tight against the TIVAR® 88 liner into the counter bore hole. In gauge thicknesses of TIVAR® 88 greater than ½” a compression fit plug of TIVAR® can be placed over the spanner nut. The process of arc welding the threaded stud takes less than a few seconds to complete. See diagrams below for exploded view of the installation.
