Intrusive Pig Indicator

EMT’s intrusive pig indicator is a detection device designed for installation on pig launchers and receivers. Its primary function is to confirm the launch or arrival of a pig—a cleaning device used in pipelines. This versatile indicator can be installed anywhere along the pipeline, making it an effective pig detection system for all types of pipelines. To avoid plugging brought on by fluid exchange, our pig indicators use a distinctive magnetic system. This design not only eliminates the risk of seal leaks during action but also reduces maintenance due to the instrument’s trigger’s flexibility.

In terms of application, our pig indicators are suitable for pipe sizes of 2 inches and above. For a 2″ flange connection, the product’s design pressure range is from ANSI 150# to ANSI 2500#. For boss connections, the maximum design pressure is 10000 psi (69 mpa). The pig indicator is designed to operate optimally at temperatures between -20 ºC and +120 ºC. We also offer special seals for working temperatures outside this range.

For the installation of the flange connection pig indicator, pre-install a flange that meets the instrument’s installation mode and requirements on the pipeline. In other words, the flange specification, grade, distribution of mounting holes, etc. should all comply with ANSIB 16.5 standards or custom standards. The distance from the top surface of the flange to the inner wall of the pipe should align with the customized size.

Maintenance of the Pig Indicators

If you notice a leak at the bottom of the flange of the device, it is likely that the seal of the device has been breached. When this happens, the device needs to be removed and the seal replaced. For externally visible seals, they can be replaced directly. However, for internal seals, we recommend returning the device to the manufacturer for replacement. Before you begin removing the flange base from the non-pressurized pig indicator, it is critical to ensure that the pipe or system has been depressurized. This is a necessary safety measure to prevent accidents. If you are disassembling the mechanism of a pressurized through ball indicator with a ball valve, you will need to use the simple tool that comes with the device. For other pressurized, detachable pig indicators, special tools are required to remove them. Always make sure you have the proper tools on hand before attempting any maintenance tasks with the pig indicator.

Routine maintenance

Once the pig is installed on the pipe, maintenance is fairly simple. It is essential for the normal functioning of the indicators that the pig passes on a regular basis. If your Pig Signaller is not working as expected or has stopped working, we recommend that you review our user manual or get in touch with us for assistance

Flag operation

After each operation, ensure that the reset is accurate. Under normal circumstances, the flag should be locked in a low position before the pig passes. When the pig passes, the flag will be raised. The flag must be reset before the next pig passes.

Product leakage

If you notice any leaks around the flagpole, it’s most likely a problem with the pressure plug or O-ring. In this case, remove the pressure plug and replace the O-ring. If there is a possibility of contamination from products around the trigger, such as wax or sand, you should remove the pressure plug and clean the trigger chamber with warm soapy water or a mild solvent.
