Scraper Passage Indicators

IK-UK’s Scraper Passage Indicators (SPI) or Pig Signallers are installed into the launcher and receiver units to confirm the launch or arrival of a pig. They can also be installed at any point along the pipeline to indicate that the pig has passed a specific point or pipeline feature.

 Local Flag Indicators, which can be manually reset, or Electronic Sensors for remote indication of pig passage can be specified.  Modern design uses magnetic interaction to initiate sensor actuation, minimising complexity and maximising reliability, safety and ease of use.

Designed to retrofit to existing installations, IK-UK SPI unites offer quality, safety and the highest product standards.
