Bidirectional Flange Pig Signaler
- EMT
- Shenyang, China
- 15 days
- 200 sets/month
The flange pig signaler is the necessary equipment in the pipeline pass-through pipe cleaning process. It is fixedly installed above the pipeline to determine whether the pig has passed the test point. It can provide information to the operator through secondary sources such as light, point, sound or special clock to guide the switching process.
Use pressure: 0-20Mpa
Operating temperature: -2-80 ° C
Pipe nominal diameter: D≥DN80
Transport medium: oil, gas, water
Bidirectional Flange Pig Signaler（Pig Passage Indicator）
EMT Pig signallers are used to provide confirmation of the movement of pipeline pigs through a pipeline. They are normally positioned at both the pig launching and pig receiving stations and at key points along a pipeline.
Benefits of EMT Pig Signallers
Three trigger type:
1. Bi-directional
2. Bi-directional Feather
3. Uni-directional
Three indicator types are available:
1. B_Manual reset flag
2. C_Manual reset flag combined with electrical switch output
3. D_Digital display combined with electrical switch output
Three mounting types:
1. 2″flange connection
2. 2″welded nipple
3. 2″welded base- NPT nipple connection
Features of EMT Pig Signallers
l Suitable for pipe sizes from 2” upwards
l A range of design pressure from ANSI 150 # to ANSI 2500 # are available for 2 "flange connection,
The highest design pressure is 10000Psi(69MPa) for boss connection.
l The working temperature range is -20ºC to +120ºC. Special seals can be provided for operating temperatures outside this range
l Trigger mechanism does not use dynamic seals therefore both prevent leakage and ensure trigger flexibility(The boss connection, with pop-up indicator or the digital display is excluded). The flag is interactivity with the trigger mechanism, therefore, the flexibility of trigger mechanism can be checked online.
l The requirement about adjusting Insert depth can also be met.
l Easy to operate, Proven durability, minimal maintenance required.
Suitable for all types of pipeline pigs such as Foam Pig, metal Bodied Pigs, Spheres, Intelligent Detection Pig
