Fabric Expansion Joint

Fabric Expansion Joint

Fabric expansion joints are essential components in industrial ducting systems and fan/blower connections. These versatile joints effectively absorb thermal growth, isolate vibration and noise, and allow for misalignments. This makes fabric joints an indispensable part of various industries, including power, petrochemical, pulp & paper, and other industrial facilities.

In this article, we will discuss the features, benefits, and applications of fabric expansion joints, making it easier for you to understand their importance in your industry. Fabric joints are a type of pipe expansion joint.

Key Features of Fabric Expansion Joints

  • Flexible and customizable design: Fabric expansion joints come in various shapes, including U-type, flat belt type, square, rectangular, and round.
  • Excellent corrosion and chemical resistance: These joints are made from durable materials that can withstand harsh conditions.
  • Baffle protection: Baffles shield the inner surface of the joint from particulates in the gas stream, extending its lifespan.
  • Retaining rings: Available in carbon or stainless steel, retaining rings provide added support and durability.

Benefits of Fabric Expansion Joints

  • Stress relief: Fabric joints provide much-needed stress relief for piping and ducting systems, preventing damage and wear.
  • Absorbing thermal growth and shock: These joints can handle thermal expansion, protecting the system from warping or breaking.
  • Vibration isolation: Fabric expansion joints absorb vibrations, reducing noise and extending the life of your duct system.
  • Easy retrofitting: You can easily incorporate fabric joints into an existing ducting system.
  • Cost-effective solution: Fabric expansion joints offer a budget-friendly way to compensate for movement in ducting systems.

Various Applications of Fabric Expansion Joints

Fabric expansion joints are widely used in numerous industries, such as:

  • Power plants
  • Waste incineration plants
  • Dust removal and filter systems
  • Cement and steel industry
  • Drying technology
  • Chemical industry
  • Conveyor technology
  • Fan construction
  • Ventilation technology
  • Marine engineering

Material Options for Fabric Expansion Joints

Fabric expansion joints can be made from various materials to suit specific applications, such as:

  • Carrier fabric: Polyester, Aramid, Glass Fiber, or Silicate Fibers
  • Insulation material: Glass Fiber, Silicate Fibers, or Ceramic Fibers
  • Sealing foils: Elastomers, PTFE, or Stainless Steel
  • Coatings: Neoprene, EPDM, Hypalon, Silicon, Viton, or PTFE

Fabric duct joints can be custom-made and are easy to transport and install. You can use them when there is low pressure and dry media. Often fabric expansion joints can be used with ducting expansion joints. In addition, bellmouth reducers with fabric joints are part of a ducting system.

In conclusion, fabric expansion joints offer a practical and cost-effective solution to handle thermal growth, vibration isolation, and misalignments in industrial duct systems. Their versatility and customizable nature make them ideal for various industries and applications. Contact us today for a quote.
