Pig Signaller With Flange

Description

China Passage Pig Signaller



China Passage Pig Signallers are used to determine whether a pig has passed or arrived. It is usually placed on the sending and receiving ends of the pig, as well as at key locations on the pipeline. And if you have any other questions, please contact our professionals to answer them for you.



Features of EMT Ball Indicator

There are three trigger modes to choose from



Bi-directional is Bi-dierctional; code B, can be omitted; 2. Bi-directional feather is Bi-directional Feather, code F; 3. Uni-directional is Uni-directional, code U



Three display output forms are optional:

B_ flag, manual reset

C_ flag is combined with switch output, manual reset

D_ digital date and time display combined with switch output, automatic reset

Three installation types:

Firstly, 2? flange is Flange, code F;

Secondly, 2? welding base is Nipple; code N;

At last, 2? welding base is R2Adjustable, code R2AJ.

Performance parameters of EMT ball indicator

Firstly, it is suitable for pipes above 2”.

Secondly, when flanged, the design pressure is from ANSI 150# to 2500#. The maximum design pressure when the nozzle is welded is up to 10000Psi 69MPa.

The working temperature range is -20?120?, the working temperature Use special seals when exceeding this range.

Then the trigger mechanism does not use a dynamic seal. Which prevents leakage and ensures the flexibility of triggering . Simple installation, little maintenance, and strong durability .

At last, insertion depth can be customized according to customer needs

EMT Pig Signaller Makes Pig Inspection Simple and Effective

EMT’s range of Intrusive Ball Indicators are instruments installed on pig transmitter and receiver stations to confirm the launch or arrival of a pig. They can also be installed anywhere on the pipeline and detect the passage of all types of pipeline pigs. Our intrusive ball indicator unit uses a unique magnetic system to prevent fluid exchange from being blocked. So it both eliminates the risk of dynamic seal leakage, increases instrument triggering flexibility, reduces maintenance costs, and is easy to install to on the pipeline. There is interaction between the flag and the trigger mechanism. So the flexibility of the trigger mechanism can be checked online.



Online Maintenance Option

-AJ: Threaded connection of branch pipe, adjustable insertion depth. It can be installed and removed under pressure using special tools.

-MFOI: Trigger mechanism flexibility can be checked online.

-REDV or RE: Installation and removal under pressure can be achieved by installing on the flanged ball valve using the installation and removal tool under pressure .

-REUV: Loading and unloading under pressure using special tools.

-REIV: Use pressure loading and unloading tools 2 full threaded studs / synchronous special tools. Which includes a ball valve. And which can realize pressure loading and unloading.

IV: Self-contained ball valve
