Fastening Methods

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”. For more installation details click the picture to the right.

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”. For more installation details click the picture to the left.

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. For more installation details click the picture to the right.

In the majority of TIVAR® 88 installations a steel leading edge protector is required around the top perimeter of the liner to prevent bulk materials from migrating beneath the panels. Leading edge protectors serve as a transition piece from the base substrate to the liner surface. Leading edge protectors can be purchased as a stock material for flat substrate installations or custom manufactured to conform to curved or radius surfaces. Leading edge protectors can be either bolted or welded on to the base substrate. For more installation details click the picture to the left.
