VIBRO CONNECTORS VRTF

VRTF double sphere rubber expansion joint is a high-performance flexible connector designed to absorb vibration, reduce noise, and accommodate multi-directional movement in piping systems. Compared to single sphere rubber joints, the double sphere configuration offers an extended installation length, effectively addressing limitations associated with short-length rubber connectors. This makes it particularly suitable for applications requiring greater flexibility and displacement absorption.

The joint comprises a dual-sphere rubber body and flanged end connections. The rubber element is formulated for softness and elasticity, allowing it to dampen dynamic forces and compensate for thermal expansion and contraction caused by temperature fluctuations. However, it is essential that the joint is installed within its rated movement limits to ensure safe and reliable operation.

Description

VRTF double sphere rubber expansion joints leverage the inherent advantages of advanced rubber compounds, offering:

  • High Elasticity & Flexibility: Accommodates axial, lateral, and angular displacements while maintaining structural integrity
  • Vibration & Noise Reduction: Effectively isolates mechanical vibration and suppresses noise transmission throughout the piping system
  • Media Compatibility: Available in various rubber formulations (e.g., NR, SBR, IIR, NBR, EPDM, CR, FKM) to suit specific chemical, thermal, and environmental conditions
  • Environmental Resistance: Provides excellent resistance to weathering, radiation, and corrosive media
  • Durability & Maintenance: Lightweight, easy to install, and maintain, with reliable sealing performance and long service life

Important Note: To prevent damage, the joint must be protected from sharp metal edges and must not be installed beyond its rated movement capacity.

Selecting the appropriate VRTF double sphere rubber expansion joint requires consideration of the following parameters:

  • Compatibility between the conveyed medium and selected rubber material
  • Full operating range of temperature, pressure, and vacuum
  • Required movement (axial, lateral, angular) based on system dynamics
  • Dimensional spacing between pipe flanges and connection type

With this information, our application engineers can assist in identifying the optimal joint configuration for your specific project requirements.

Due to its superior flexibility and vibration isolation properties, the VRTF double sphere rubber expansion joint is widely used in:

  • Raw Water & Sewage Transfer Systems
  • Cooling Water Circuits in Thermal Power Plants
  • Metallurgical and Chemical Process Pipelines
  • Condensate and Petrochemical Transport Lines
  • Flexible Connections in Long-Term and Temporary Installations
  • Granular, Powder, and Low-Temperature Gas Conveyance

Its wear-resistant rubber composition also makes it suitable for abrasive media and dynamic flow conditions across various industries.

For custom applications, OEM and ODM services are available. To determine the ideal double sphere rubber expansion joint, it is essential to evaluate:

  • Medium compatibility with selected rubber material
  • Full temperature, pressure, and vacuum range
  • Required movement characteristics
  • Flange-to-flange dimensions

Our engineering team is ready to support your selection process and ensure optimal performance for any application.

  • Reinforcement Layer: High-strength cotton cord fabric for structural integrity and pressure resistance
  • Outer Layer: Aging-resistant rubber for long-term durability in exposed environments
End Connection Material:
  • Forged or cast steel (available in round or square profiles)
  • Surface finish: Galvanized for corrosion protection and extended service life

VIBRO CONNECTORS VRSF

VRSF flexible expansion joints commonly referred to as rubber joints are engineered to absorb movement, isolate vibration, and reduce noise in piping systems across a wide range of industrial applications. These joints are widely utilized in water supply and treatment, electrical utilities, chemical processing, and marine mooring systems due to their robust performance and versatile material compatibility. The rubber body of each expansion joint is constructed using a multi-layered vulcanization process:
  • Inner Layer: Tailored to suit the conveyed medium, using rubber types such as NR, SBR, IIR, NBR, EPDM, CR, FKM, etc., depending on chemical and thermal requirements
  • Reinforcement Layer: Made of high-strength nylon cord fabric to ensure pressure containment and structural integrity
  • Outer Layer: Composed of aging-resistant polar rubber for long-term durability in exposed or corrosive environments
To prevent natural shrinkage, premature aging, and cracking during extended service life, embedded steel wire reinforcements are incorporated for added structural protection and dimensional stability.
