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.

Gasket
Gasket are recommended for any metal to metal installation. We stock several widths of fiberglass gasket tape as well as PTFE coated fiberglass products. Our extruded PTFE gasket tape is ideal for fabric to metal installations or when a highly compressible, chemical resistant seal is needed. Let us provide all of the gaskets required for your expansion joint installation to avoid costly delays and misplaced parts needed during installation.

Fasteners
Flexible Specialty Products can provide any necessary mounting fastener for your expansion joint application. We will properly size the fasteners and provide standard grade or any specialty fastener required. The fasteners will be packaged with the expansion joint shipment to assure the fasteners will be on-site when needed to avoid costly delays or misplaced parts.

Custom Cold-Cold Gas Turbine Expansion Joints
Cold to Cold gas turbine expansion joint configurations use threaded rods to attach internal flow liners. No part of the mounting frame is subjected directly to the hot gas flow. This frame type typically uses a carbon steel framework on each side with stainless steel flow liners. Both sides of adjacent ductwork have internal insulation and internal shrouds that tie directly into the expansion joint’s flow liners.

Custom Hot-Cold Gas Turbine Expansion Joints
Hot to Cold gas turbine expansion joints have a stainless steel or alloy steel framework on the hot side and a carbon steel frame on the cold side. The two expansion joint frameworks are designed to accommodate two different bolt patterns and provide the required protection of the frameworks and outer composite belt. Drains can be added to accommodate water washing of the turbine or ductwork. Internal liners can be welded to the hot side while they are typically suspended with rods on the cold side to provide an internal laminar flow surface.

Custom Hot-Hot Gas Turbine Expansion Joints
Hot to Hot-type gas turbine expansion joints have frameworks on the upstream and downstream sides that are exposed to the full temperature of the gas flow. The upstream and downstream frames can accommodate two different bolt patterns as needed and are fabricated from stainless steel or other alloy designed to handle full design temperature. This type of framework can have many configurations that can allow slip-in installation or access to all fasteners for ease of maintenance.
