Twenty years underground

Tianjin Chiyu Technology Co., Ltd. builds detection instruments for the networks nobody sees — and has spent two decades learning where they actually are.

Who we are

An instrument maker, run by field engineers.

Chiyu started where most equipment companies end up: on site, running surveys for gas companies, municipal utilities and petrochemical operators across China. Building our own instruments was the logical next step — we knew exactly where imported equipment was over-priced, over-complicated, or simply wrong for local ground conditions.

Today we design and manufacture ground penetrating radar, pipeline and cable locators and coating fault detection systems in Tianjin, and support them for operators across China, Southeast Asia and Central Asia.

  • In-house engineeringCore radar and locator hardware developed and produced by our own team.
  • Field-first designEvery product is validated on real surveys before it reaches a price list.
  • Honest specificationsPerformance figures come from project records, not marketing drafts.
