Intrusive Omni Directional Pig Signallers
Contact PE:
Pig signallers are installed on pipelines to detect the passage of pigging tools and spheres.
The PE Intrusive Omni Directional Pig Signaller is suitable for flange, boss or hot tap applications.
The PE Intrusive Omni Directional Pig Signaller is a mechanical or mechanical-electrical unit without dynamic seals that uses magnets to release a flag to indicate the passage of pigging tools or spheres.
The trigger is operated by a non-orientation sensitive (omni directional) trigger mechanism.
The Omni Directional Pig Signaller can be supplied as flange mounted, conventional welded boss mounted, mounted via an isolation valve or compatible with hot tap boss.
Benefits of the PE Omni Directional Pig Signaller include:
- No dynamic seals avoiding possible leak paths
- Ease of orientation during installation due to omni directional trigger
- Easy to install due to compact nature and lightweight
- Suitable for all pipelines over 2” in diameter
- Where specified, can be removed under pressure with hot tapping tools & adaptors
- Can be fitted with isolation valve enabling maintenance without shutting the line down
- Flag indicator latch closed to prevent any environment induced trips (e.g. due to high winds)
Features of PE Pig Signallers include:
- Compact and lightweight
- Can be specified for installation into hot tap bosses using standard hot tap tools
- Can be specified for subsea use
- Can be specified with self-coloured flag
- Hot tap unit incorporates a unique thread sweeping ring to avoid failed installations due to thread jamming
- Can be supplied with Eexd rated proximity switches and junction box to provide electrical signals independent to the mechanical flag
