The Leg-Out-style ductwork frame uses a fabricated angle frame with a composite belt cover attached directly to the frame using studs and backing bars or heavy-duty band clamps. This style of expansion joint can be assembled with an internal flow liner for abrasion protection. The mounting holes are easily accessible for quick installation and the frame can be fabricated from carbon steel, stainless steel, or other alloys.

Flow Liner
All expansion joints can be supplied with various configurations of flow liners. Flow Liners can be supplied as bolt-in unit design, single, tapered, overlapping, and floating. The primary purpose of flow liners is protection of the internal insulating materials from abrasives in the gas flow. They are also used to secure the internal accumulation pillow in place as well as to provide a laminar flow in the area of the expansion joint. Flow liners need to be designed to allow full system design movements while providing the necessary protection and support. Many materials of construction are available including carbon steel, stainless steel, Corten, AR Plate, and special alloys. Check with FS Products to see how flow liners can increase the life of your expansion joints.
