Pig Signallers

Pig signallers are used to indicate the pig has left the launcher, arrived in a receiver or passed a certain point in the pipeline. iNPIPE PRODUCTS™ signallers are designed to operate through 360⁰, this unique design feature ensures that it is impossible to install in an incorrect orientation.

The pig signaller is used to indicate the pig has left the Launcher, arrived in a receiver or passed a certain point in the pipeline. The iNPIPE PRODUCTS™ pig signaller range is reliable and effective regardless of the orientation in which it is fitted due to an omni-directional trigger design.

This simple design feature means that it is impossible to fix the signaller on to the pipeline or pig trap in the wrong orientation. Some pig signaller designs are bi-directional that means that they can be fitted by accident offset from the line of pig travel and therefore cannot work. The iNPIPE PRODUCTS™ signaller was designed with ease of fitting in mind, using either a threaded boss of flange mounting, as it operates in 360⁰ it is almost impossible to install incorrectly. The signallers can also be monitored remotely using electrical switches, linked into SCADA systems or even through a satellite linked GPS system which can send a signal directly to your mobile. You can therefore be updated on your pig passage anywhere in the world direct to your phone.

The iNPIPE PRODUCTS™ pig signaller is a proven design, approved and used by most international operators and contractors, and we have units still working for worldwide operators over 25 years old. Our patented design ensures that the flag and/or electrical switch is locked into place with our safety catch and will only operate as the pig passes, it is impossible for the signaller to falsely operate under line pressure/product flow unlike some designs. Like any piece of equipment however physical accidents can happen so the iNPIPE PRODUCTS™ design can be easily removed under line pressure and replaced without problem. To accommodate buried pipelines we have developed signaller removal tools to client specification up to over 2 metres in depth. All designs and products undergo full factory acceptance testing under pressure, often under independent third party inspection, before dispatch.

iNPIPE PRODUCTS™ is also somewhat unique in that the company can supply a combination of intrusive and non-intrusive pig signalling equipment dependent upon client requirements and specifications. Subsea options in intrusive and non-intrusive form are readily available upon request.
