Pipe Tracers / Flexitrace

Pipe tracers and Flexitrace systems together address the full range of buried pipe identification and route mapping requirements encountered across utility maintenance and construction survey work, covering both metallic and non-metallic pipeline types within a single combined equipment approach. Electromagnetic pipe tracers handle metallic targets including steel water mains, copper service lines, and cast iron drainage pipes, while the Flexitrace mechanical rod system extends tracing capability into non-metallic pipes including PVC, HDPE, and vitrified clay drainage lines that carry no conductors for electromagnetic signal induction.

Electromagnetic pipe tracers inject a specific frequency signal onto the target metallic pipe through direct clamp connection at an access point, allowing the surface receiver to isolate and follow that single pipe through congested underground corridors containing multiple adjacent utilities. Frequency selection covers 8 kHz standard tracing through 33 kHz high-frequency mode for shallow congested installations, with adjustable transmitter output power between 0.1W and 3W preventing signal bleedover onto adjacent metallic infrastructure. Additionally, null detection mode on compatible receivers identifies pipe centerline through minimum signal point rather than peak, improving lateral accuracy in areas where broad peak responses make precise centerline marking difficult.

The Flexitrace rod system uses interconnecting 1-meter fiberglass rod sections pushed through the non-metallic pipe bore from an access point, with a battery-powered 512 Hz sonde transmitter attached at the leading tip. The surface operator tracks the sonde signal above ground using a compatible receiver, marking the pipe route at the surface directly above detected sonde positions as the rod team advances the assembly through the pipe interior. Furthermore, total rod set lengths run between 30 and 90 meters from a single entry point, covering most standard drain and service pipe survey requirements without requiring additional access excavation along the pipe route.

Both systems work with compatible multi-frequency receiver wands that switch between electromagnetic pipe tracing and sonde tracking modes through a single frequency selection menu, removing the need for separate receiver hardware across the two tracing methods. Moreover, rod sections withstand contact with standing water, silt, and drainage chemical residues without degradation during insertion and retrieval operations.

Tactical Supply Pakistan supplies pipe tracers and Flexitrace systems to drainage contractors, water utility authorities, municipal engineering departments, and civil engineering teams requiring complete metallic and non-metallic buried pipe tracing capability across utility survey and construction projects throughout Pakistan.
