XB Rectangular Duct Fabric Expansion Joint

Overview

Fabric Expansion Joints utilize a composite fabric material as the flexible element of the expansion joint. They are typically used in low pressure ducting applications to compensate for misalignment, vibration and thermal growth. Fabric expansion joints can be designed with composite fabric with integral insulating layers or separate insulation pillows to handle temperatures in excess of 1000˚F.
Fabric Expansion joints can used to compensate thermal growth in ducting and misalignment without the spring loads typically associated with metal expansion joints. Fabric expansion joints can also absorb large lateral movements or misalignments. Additional components, like flow liners, insulation blankets and accumulation barriers can be added to the fabric expansion joint depending on the application and service.

Single rectangular metal expansion joints have limited ability to absorb lateral offset or deflection. If lateral offset is a requirement a universal configuration is recommended or two single joints spaced apart. If the motion is limited to one plane, hinges or slotted hinges are frequently included. Slotted hinges have the benefit of stabilizing the expansion joint, limiting the axial travel and supporting the weight of adjacent ducting. The joint pictured is used in the exhaust stack of a ship. The rounded . ends are made from round expansion joints cut in half. This is the same technique is used to made round corners of rectangular expansion joints
