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
