The Thread-O-Ring™ is a high-performance intrusive pig passage indicator designed to seamlessly integrate into existing Thread-O-Ring™ nipple fittings. It provides precise, reliable detection of cleaning pigs as they move through the pipeline. When a pig activates the intruding plunger, the device signals its passage via a visual flag indicator and/or an electrical switch.
Designed to be installed into an existing THREAD-O-RING™ nipple fitting, this Apache pigPRO™ indicator is a member of the patented line of intrusive pig passage indicators that reliably detect the precise location of a cleaning pig as it travels within the pipeline network. When a cleaning pig passes the pigPRO’s intruding plunger, it activates the plunger and triggers a visual flag indicator and/or an electric switch, signaling the pig’s location.
Shown with Series 57 which includes visual flag indication, manual reset.
Also available in Series 55 which includes electrical switch with automatic reset, or Series 53 which includes both the visual flag indication and electrical switch. Flanged options are available for all styles.
Aluminum extensions can be attached to enable detection of the pig’s passage on buried pipelines. All pressure sealing components remain below the extension module. Available in lengths 2′ to 10′.
