A Fabric Expansion Joint is a flexible connector installed in piping and duct systems to absorb thermal expansion, pressure fluctuations, and vibrations, preventing damage and ensuring system integrity. Composed of layers of fabric belts, sometimes combined with metal reinforcements, these joints accommodate movement in multiple directions, making them ideal for systems exposed to high temperatures and pressures, such as in power plants, chemical processing and HVAC systems. By compensating for misalignment and reducing stress on other components, Fabric Expansion Joints enhance the durability and longevity of the pipeline or duct work.
● Construction :
# Fabric layers : The expansion joint comprises multiple layers of high-performance fabric designed to handle temperature variations, pressure, and movement.
# Flanges : Both sides of the expansion joint are equipped with flanges, which include multiple pre-drilled holes for secure fastening to pipes using nuts and bolts.
● Reinforcement :
# Wire mesh : An external wire mesh is applied around the fabric layers to provide additional support and withstand extra pressure in high-stress environments.
● Materials :
# Flange materials : The flanges are available in Mild Steel (MS) or Stainless Steel (SS), offering options for different operating conditions and environments.
# Tie rods : The expansion joint includes tie rods for added structural integrity and to manage axial forces.
A High-Temperature Fabric Expansion Joint is a specially designed component comprising multiple layers of high-temperature-resistant fabric. These joints are engineered to withstand extreme temperatures, up to 1400 degrees Celsius, while allowing for flexibility and movement in high-temperature industrial applications. They are essential in environments where thermal expansion or vibration might otherwise cause damage to rigid structures.
● Rectangular type :
# Design Features : They are typically used in duct systems with rectangular cross-sections. It allows for large lateral movements and can be designed to accommodate various dimensional constraints.They are often used in large ducts in power plants, refineries, and other industrial settings.Flanges are usually provided for bolted connections to the ducting.
# Advantages : It can be customized to fit irregular duct shapes.Suitable for high-temperature and high-pressure environments.
# Applications : Power generation facilities, Refineries & Industrial ventilation systems.
● Square type :
# Design features : A sub type of rectangular expansion joints, square shapes are used when both duct dimensions are equal. It provides the same flexibility as rectangular joints but is used in more symmetric applications. It can also accommodate large lateral and axial movements.
# Advantages : It simplified the design and ease of installation. It can be tailored to fit specific system requirements.
# Applications : Where ducting systems require uniform movement absorption in both dimensions. Industrial applications with square duct configurations.
● Circular type :
# Design features : They are designed for circular ducting systems, often used in pipes or ducts carrying gases, vapors, or particulates. It offers 360-degree flexibility and effectively accommodates axial, lateral and angular movements. It can be manufactured in various diameters to fit different pipe sizes.
# Advantages : High flexibility in all directions. It is ideal for round ducts where even stress distribution is needed.
# Applications : HVAC systems, Industrial exhaust systems & Pipelines carrying fluids or gases.
