U.S. Bellows designed fabric expansion joint for a textile sheets, polymer, and fiber plant in Virginia. The dimensions for the expansion joints are 36" long, 24-1/2" wide, and 24-1/2" long. These fabric expansion joints are fabricated of carbon steel flanges with 1-ply reinforced silicone fabric. The expansion joints are designed for 300°F with an operating pressure of 3 psig, and movement of 6" lateral. A dye penetrant examination on the welds was performed prior to shipment.

Fabric expansion joints are used in a wide array of applications playing a crucial role in preventing damage to equipment, ensuring system reliability, and maintaining overall safety in industrial processes. Some examples of where they are used are:

  • Cement plants for ducts and exhaust systems associated with high temperature operations.
  • Mining industry for mineral and material handling including smelting.
  • HVAC systems for duct work to address any thermal movements or vibrations.
  • Marine and shipbuilding applications where exhaust systems, engine piping and other critical areas movement and vibrations must be managed.
  • Renewable energy facilities such a waste to energy or bioenergy plants in which the incineration operations are critical.
  • Paper and Pulp mills for ducting systems in drying and paper manufacturing processes.
  • Steel Mills for blast furnace systems and exhausting ducts.
  • Chemical plants to handle dynamic forces associated with chemical reactions, temperature variations and corrosive environments.
  • Power plants Fossil Fuel and Nuclear plants to manage vibrations and thermal axial expansion that could stress components and fixed equipment.

We have a 24/7 field service team that works on fabric expansion joints. One of our loyal customers, a North American-based energy company, reached out to us for warranty work on one of our Fabric Expansion Joints and our fierce Fabric Expansion Joint team lead, stepped in and stepped up! She flew up to West Virginia and completed the work. We are dedicated to the success of our products in the field even after they leave our plant.

 Testing:  100% Dye-Penetrant

U.S Bellows fabricated these fabric expansion joints for a carbon gas application at an oil and gas facility in Louisiana. These units are 20″ in diameter and 18" in length. The 1-ply fabric belt is made from PTFE, and the framework is carbon steel. They are designed for an operating temperature of -20°F/+600°F with a +/- 20" water column and +/- 1" of axial compression and lateral offset. The welds of the units were dye penetrant tested prior to shipment.

US Bellows and its subsidiaries have served as leading global suppliers of carbon black worldwide. Material from these plants is made to exacting standards for tires, coatings, ink, batteries, plastics, and numerous other specialty high-performance applications. Carbon black is produced from the thermal decomposition of heavy petroleum raw materials, such as coal tar, ethylene cracking tar, or FCC tar. It is widely utilized owing to its various beneficial characteristics, including surging tire tread wear and rolling resistance, effectively absorbing ultraviolet (UV) light and converting it into heat, improved thermal conductivity, and superior UV protection. Several processes, such as oil furnaces and thermal, are mainly used to manufacture carbon black. In addition to providing expansion joints, we have provided the following products from our portfolio of manufactured in our facility in Houston, Texas:

  • Constant Spring Hangers
  • Metallic Expansion Joints
  • Pipe Shoes, Guides, and Anchors
  • Insulated Supports
  • Paddle Blinds and Spacers
  • Pipe Hangers Hardware
  • Slide Bearing Plates
  • Instrument Supports
  • Variable Spring Hangers
