FUB Rubber Flue Duct Expansion Joint

Overview

Flue duct expansion jointsare custom engineered to handle low pressure (±3 psig) applications with temperatures ranging from -100°F to more than 2000°F. Industry Proven materials and precise engineering go into every LUOYING Fabric Expansion joint.

A variety of styles and materials are available to optimize the design to meet the specific requirements of any given application. Our application engineers combine different steel frame types and industry proven belt fabric materials and options. In some instances, additional components such as insulation pillows, accumulation barriers or flow liners are used to help protect the fabric material. The basics are shown below, but a number of other design elements are possible. Also of interest may be our fully molded rubber duct expanion jonts, which can provide additional movements and ease of installation for flanged applications.

Frame types can be broadly split into two clamping styles. The belt type uses a flat belt flexible element made as a flat belt, and is the most effective in terms of manufacture and installation. And they allow many different types of frames to suit operating conditions. The flange type uses integrated flanges at right angles, and provides the simplest method of connection. Various baffles (liners) are also commonly used in both types of frames, depending on the service.

Features

 Features:
1.Good repeated displacement(change) reduction, it can make displacement from different directions in small size range, it can eliminate multilateral inaccuracy during pipeline installation and connection.
2.Excellent acoustic isolation function, and can effectively reduce and eliminate fan and blower sound and vibration transfer.
3.Rubber transfer loss, reduced design procedure, no need to add other auxiliary facility.
4.Good performance of high temperature resistance and corrosion resistance, never rust, reduce maintenance cost.
5.Excellent air tightness and flexibility, can guarantee the conveying medium no leakage and restore to original condition after repeated displacement.
