Description
EMT Pig Signaller flange connection are used to provide confirmation of the movement of pipeline pigs through a pipeline. So they are normally positioned at both the pig launching and pig receiving stations and at key points along a pipeline.
Certainly, EMT’s range of intrusive pig signallers are detector instruments mounted on pig launcher and receiver stations to confirm the launch or arrival of a pig. Mountting them at any location on a pipeline and will detect the passage of all types of pipeline pigs. Moreover, our intrusive Pig Signaller flange connection 20 mm adjustable uses a unique magnetic system to prevent fluid exchange blocked. Therefore, it eliminates the risk of leakage from the action seal. Also the trigger of the instrument is enhanced flexibility, reduces maintenance costs and is easy to install to pipelines.

Features of EMT Pig Signallers
- Firstly, it is suitable for pipe sizes from 2” upwards
- Similarly, 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.
- The working temperature range is -20ºC to +120º. So special seals can be provided for operating temperatures outside this range
- 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). In addition, The flag is interactivity with the trigger mechanism. Therefore, the flexibility of trigger mechanism can be checked online.
- The requirement about adjusting Insert depth can also be met.
- And then, 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.
