Sig-Tech® Intrusive Pig Signaler
Easily Detect Passage of Pigs in a Pipeline
Reliable detection system for cast polyurethane and spherical type pigs with multiple signaling options
Overview
The Sypris® Technologies Sig-Tech® intrusive Pig Signaler can be installed at pre-determined intervals on pipelines to detect the passage of a cast polyurethane pig or spherical type pig.
A trigger extending into the pipeline through a welded boss fitting that will trip when a pig passes, immediately activating the signaling mechanism. The Sig-Tech® pig signaler is easy to install into the boss, and with correct tools can be installed under operating pressure.
Weather and corrosion resistant, the Sig-Tech® is designed to function in the most demanding onshore or offshore environments. With a multitude of signaling mechanisms, there is a model to meet almost any need.
