FABRIC EXPANSION JOINT
Floating Sleeve Construction
When air and hot gas duct systems require superior flexibility and high-temperature resistance, Enerkeit's fabric expansion joints are the engineering solution by design. We specialize in the custom manufacturing of non-metallic joints, designed to absorb large movements in complex geometries where metal or rubber joints are not viable.
Our solutions are the standard in low-pressure systems for handling combustion gases, hot air, and other gaseous media in the most demanding industries.
Fabric expansion joints with floating sleeve construction are commonly used in plants with:
CONTACT US- Medium to high temperatures (up to 600°C).
- Very high dust content.
- Low to high flow velocities.
APPLICATIONS
- ✅ Adaptability to Complex Geometries: They are custom-manufactured for square, rectangular, circular, or oval ducts, ensuring a perfect fit.
- ✅ High Temperature Resistance: Thanks to their multilayer construction with insulating materials, they can operate in systems with gases up to 1000°C (1832°F).
- ✅ Lightweight and Low Load: Their fabric construction does not add structural stress to ducts and supports, unlike heavy metal joints.
- ✅ Chemical Resistance: We select barrier materials, such as PTFE, to guarantee compatibility with corrosive gases and acidic condensates.
- ✅ Excellent Acoustic and Thermal Insulation: In addition to absorbing movement, they reduce noise transmission and heat loss in the system.
MATERIALS
- External Layer: The first barrier against the environment. Generally made of silicone-coated fiberglass fabric, protecting against weathering, moisture, and mechanical damage.
- Insulation Layer: Composed of materials like ceramic fiber or fiberglass, acting as a thermal shield to protect internal layers from high gas temperatures.
- Chemical & Gas Barrier (Seal Layer): The most critical component. A PTFE (Teflon®) membrane or similar compound guarantees total gas impermeability and resists chemical attack.
- Internal Layer: A stainless steel mesh or fiberglass reinforcement that protects the chemical barrier from direct contact with abrasive particles in the gas flow.
Multilayer Construction: Engineering for Every Condition
The secret to a fabric expansion joint's performance lies in its multilayer design, where each material plays a critical role.
1. Outer Layer: The first barrier against the environment. Typically made of silicone-coated fiberglass fabric, it protects against weathering, moisture, and mechanical damage.
2. Insulation Layer: Composed of materials such as ceramic fiber or fiberglass, this layer acts as a heat shield, protecting the inner layers from high gas temperatures.
3. Chemical and Gas Barrier (Seal Layer): The most critical component. A PTFE (Teflon®) membrane or similar composite ensures complete gas impermeability and resists chemical attack from fluids.
4. Inner Layer: A wire mesh or fiberglass reinforcement that protects the chemical barrier from direct contact with abrasive particles in the gas stream.
