HIGH PERFORMANCE MATERIAL ASSEMBLY WHERE FLEXIBILITY MEETS PERFORMANCE

FABRIC EXPANSION JOINTS

They are vital components in industrial plants that have equipment to equipment air transfer. These are installed on duct and in piping systems that are often subject to thermal expansions, vibrations and misalignments.

Expansion Joints design and engineering is vital to reducing operation down-time and increasing efficiency. A well designed expansion joint leads to less uninterrupted plant performance and less maintenance down time.

ADVANTAGES

• Low CAPEX.

• Easy to transport, easy to install.

• Compensates for movements in several directions simultaneously.

• Minimal reactive forces.

• Advanced insulation design ensures minimal heat loss.

• Reduced surface temperature on the outer layer during operation to protect site personnel.

• Requires little space and little down time for installation.

• Easily adapts to existing physical conditions.

APPLICATIONS

Fabric expansion joints are found in a wide range of industries including:

• Chemical / Petro.

• Chemical Process Plants.

• Cement Manufacturing.

• Pulp and Paper Industry.

• Power Stations.

• Refineries.

• Shipbuilding.

• Steel Plants.

• Sugar Plants.

• Gas Turbine Installations.

• Incineration Food Processing.

CRITERIA FOR APPLICATIONS & DESIGN

Type Of Expansion Joint
Which type of NMEJ (Non-Metallic Expansion Joint) to use and its design is based on some basic considerations.
It is necessary to review operating data and other conditions in as detailed manner as possible to ensure maximum operational reliability.
Place and conditions of installation must be considered before choosing the expansion joint design. Is the place of installation easily accessible, or is scaffolding, a crane or other equipment required to install the expansion joint?

• Axial Compression
• Axial Elongation
• Angular Offset
• Lateral Offset
• Torsion

• Vibrations
• Structural-Borne Noise

• Positive Pressure (Normal, Peak)
• Negative Pressure (Normal, Peak)
• Variations Of Pressure (Pulsations)
• Pressure Surges
• Design/Operating Pressure

• Air, Clean, Dust Content, Chemical Load By Acids, Solvents, Etc.
• Flue Gases: Coal, Gas Firing, Humidity, Flyash, Flyash.

• Air, Clean, Dust Content, Chemical Load By Acids, Solvents, Etc.
• Flue Gases: Coal, Gas Firing, Humidity, Flyash, Flyash.

The Main Considerations Concerning Solid Matters Are:
• Content (Mg/Nm3)
• Grain Size (Mm)
• Arrangement Of Duct (Horizontal, Vertical, Diagonal)
• Direction Of Flow (Upwards, Downwards)
Axial compression
Axial Elongation
Angular Offset
Lateral Offset

DESIGN CONFIGURATION

The multilayer expansion joint is generally made from:

  1. Flange side material; to avoid abrasion.
  2. Outer layer; to resist the weather conditions.
  3. Sealing foil / layer; for gas tight construction.
  4. Layers; against mechanical loads.
  5. Innermost layer; protection against internal ensuring strong abrasion.
  6. Mechanical reinforcement ring.

ASSEMBLY & TRANSPORTATION

Pre-assembled expansion joint units can be supplied with surface treatment that is corrosion resistant (standard) and resistant to high temperatures.

TEXFLEX is offered in any RAL colour code for the units.
