Component Specifications

Definition
Flexible connectors are engineered components used in industrial ducting systems to absorb vibrations, compensate for thermal expansion/contraction, accommodate misalignment between connected ducts, and reduce noise transmission. They typically consist of a flexible membrane or bellows structure made from durable materials, often reinforced with fabric or metal, and include flanges or connectors for secure attachment to rigid duct sections.
Working Principle
Flexible connectors work by utilizing their elastic or accordion-like structure to deform under mechanical stress, vibration, or thermal changes. This deformation absorbs energy that would otherwise transfer through the ducting system, preventing damage to equipment and reducing noise. They maintain a sealed connection while allowing controlled movement in multiple axes.
Materials
Common materials include: synthetic rubber (EPDM, neoprene, silicone), fabric-reinforced elastomers, stainless steel bellows, aluminum, and composite materials. Reinforcement layers often incorporate polyester, fiberglass, or aramid fibers. Temperature resistance typically ranges from -40°C to +200°C depending on material.
Technical Parameters
  • Flange Types Plain, flanged, or band-clamp connections
  • Diameter Range 50mm to 2000mm
  • Pressure Rating Up to 25 kPa

Frequently Asked Questions

What are the main benefits of using flexible connectors in ducting systems?

Flexible connectors reduce vibration transmission, compensate for thermal expansion, accommodate installation misalignments, decrease noise levels, and prevent stress damage to connected equipment.

How often should flexible connectors be inspected and replaced?

Inspect every 6-12 months for cracks, deformation, or material degradation. Replace every 3-5 years depending on operating conditions, or immediately if visible damage or leakage occurs.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
