FS CASING SEAL

  • Seals the internal pressure in the pipe

  • Viton and HNBR material as standard

  • Suitable for a range of pipe media

  • Energised during installation

  • Built-in anti-extrusion springs

COUNTER WOUND HELICAL

RETAINING WIRE

  • Holds the coupling in place

  • Resists shear and compression loading of the pipe

  • Flexibility for ease of installation

  • Threaded termination assists insertion and extraction

  • Ports plugged with grease nipples to prevent ingress

PIPE GROOVE

  • Retains the wire within the pipe

  • Located between sealing systems to protect against contact media

  • Groove depth is always above the minimum allowable wall thickness

COUPLING BODY

 

  • Houses inner components and reinforces the radial strength of the pipe

  • Designed to ASME B31.3 and the pipelines mechanical specification

  • Material chosen in accordance with pipe spec

ENVIRONMENTAL  SEAL

  • Prevents ingress of external impurities

  • Protects retaining wires by blocking access to the internal bore of the coupling

  • Polyurethane material

MACHINED PIPE END

  • Surface finish allows for high quality seal

  • End bevel for ease of insertion
