TWINFLEX S

Feature

  • High Efficiency for Vibration and Noise Isolation
    The twin sphere makes the spring constant small, decreases the body natural frequency and increases the
    efficiency of vibration absorption.
  • Withstandability
    It can withstand a bursting pressure of over 5.0MPa and a maximum working pressure of 1.6MPa and with
    the combination of excellent formative technique and strong chemical fibre.
  • Large Displacement Absorption for Eccentricity, Axial Movement and Angular Movement
    Since it can absorb large displacement, TWINFLEX screwed type flexible rubber joint is most appropriate
    for the protection of pipe line system. For example, it can prevent the destruction of connecting pipe
    due to earthquake and subsidence of ground.

  • Applicable for both Suction and Delivery
    The joint fits for both suction and delivery.
  • Highly Reliable
    The packing parts are strengthened with steel reinforcing rings to prevent the rubber body from slipping
    out of the fitting sides of flanges.
  • Convenient to install
    When limited space is allowed for installation, the free type sockets can be screwed separately to pipe
    before fitting in the joint.
  • Durability
    Reciprocating pressure test for 20,000 cycles or above.
