Chiyu builds ground penetrating radar, pipeline and cable locators and coating fault detectors — made in our own Tianjin factory and used on gas, oil, water, power and telecom networks. Tell us your site conditions and we will spec the instrument, the antenna and the configuration with you.
Every instrument is configured for the field conditions our customers actually face — congested urban ducts, deep trunk lines, corrosive soils and long transmission corridors. Prices and lead times are quoted per configuration, so ask us directly.

Two antenna bands in one probe: a single scan reads shallow services and deep trunk mains at the same time.

Maximum penetration for deep trunk lines, strata interfaces and tunnel advance prediction.

The balance point between resolution and depth — the workhorse for municipal and road survey.

The TD9800-MFC puts two antenna bands in a single cartridge. A single scan captures small-diameter shallow services and large-diameter deep trunk lines — no second pass, no re-mobilisation, and cross-band comparison on the same line.
We work to the international utility colour code, because that is the language our customers use on site every day.
Route mapping, coating fault surveys and depth-of-cover verification on distribution and transmission networks.
Find non-metallic mains, leaks and unmapped services that conventional metal detectors miss.
Cable route tracing and depth verification ahead of metro, road and foundation works.
Precise duct and fibre location to protect backhaul routes during civil works.
City-scale utility mapping and void detection that feeds directly into GIS and as-built databases.
Rebar, void and buried service investigation inside refineries, power plants and sensitive sites.
Selected work from 20+ years of underground detection — each case lists the equipment used and what the customer got out of it.

Rebar gaps and voids under operational concrete aprons were mapped without closing the field — the wireless antenna let the crew wor…

Full-length coating condition assessment on a long-distance oil pipeline in difficult terrain, with faults graded for a prioritised …

A complete underground utility database for a city district, delivered to GIS-ready standards and used as the base layer for later e…
Radar and locator hardware developed and built in-house in Tianjin — configuration changes and OEM options are part of the conversation, not an exception.
±3 to ±5 cm positioning and detection depth to 30 m, validated across 500+ projects rather than in a brochure.
English documentation, international logistics and remote commissioning support for customers across Southeast Asia, Central Asia, the Middle East and Africa.
A technical team that answers while you are on site — spare parts, training and troubleshooting within one working day.
Send your site conditions — target type, depth range, soil and access — and an engineer will come back with a configuration, lead time and quotation. No price lists, no guessing.
