SRJ Coupling 

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
