EMT - Bidirectional Flange Pig Signaler
The Bidirectional Flange Pig Signaler is an integral tool for the pipeline cleaning process. It is securely installed over the pipeline to detect the passage of pigs at specified points, aiding in the operational control during pigging activities. This device offers secondary indication mechanisms such as lights, points, sounds, or special clocks to alert operators. Designed to ensure accurate tracking of pipeline pigs, it is installed at both launching and receiving stations, as well as at strategic points along the pipeline to confirm pig movement bidirectionally. Available in manual reset flag, manual reset flag with electrical switch output, and digital display combined with electrical switch output variants, it features three mounting types: 2″ flange connection, welded nipple, and welded base-NPT nipple connection. Capable of handling pressures from ANSI 150# to ANSI 2500# and working temperatures from -20ºC to +120ºC, it includes a trigger mechanism without dynamic seals to prevent leaks and ensure flexibility. Compatibility with various pig types and minimal maintenance requirements make it suitable for a range of pigging applications.Most popular related searches

The Bidirectional Flange Pig Signaler is the necessary equipment in the pipeline pass-through pipe cleaning process.Bidirectional Flange Pig Signaler is fixedly installed above the pipeline to determine whether the pig has passed the test point. Bidirectional Flange Pig Signaler can provide information to the operator through secondary sources such as light, point, sound or special clock to guide the switching process.
Three trigger type:
- Bi-directional
- Bi-directional Feather
- Uni-directional
Three Pig Indicator types are available:
- B_Manual reset flag
- C_Manual reset flag combined with electrical switch output
- D_Digital display combined with electrical switch output
Three mounting types:
- 2″flange connection
- 2″welded nipple
- 2″welded base- NPT nipple connection
- It is suitable for pipe sizes starting from 2" and above.
- Various design pressure options are available, ranging from ANSI 150# to ANSI 2500# for the 2" flange connection.
- The boss connection can handle the highest design pressure of 10,000 Psi (69 MPa).
- The working temperature range spans from -20ºC to +120ºC. In case of operating temperatures outside this range, special seals can be provided.
- The trigger mechanism of the signaller is designed without dynamic seals, ensuring both leak prevention and
- trigger flexibility (excluding the boss connection with pop-up indicator or digital display). The flag of the signaller
- is interactive with the trigger mechanism.
Furthermore, the online checking of the trigger mechanism's flexibility is possible.
- It can fulfill the need for adjusting the insert depth as required.
- The Pig Signaller is designed for ease of operation, demonstrating proven durability and requiring minimal maintenance.
- It is compatible with various types of pipeline pigs, including Foam Pig, Metal Bodied Pigs, Spheres, and Intelligent
- Detection Pig, making it suitable for diverse pig applications.
