Technical Innovation of Pipeline Crawler
Yang Liu, Shuxia Li · Petroleum Engineering Construction · 2009
In non-destructive tests for long-distance pipelines, traditional pipeline crawlers use radioactive isotopes as the instruction resources which emit gamma rays harming human and environment to a certain extent. To solve this problem, a new kind of operational control system with magnetic positioning sensors was developed. The configuration, working principle and performance characteristics are introduced in this paper. The new crawler possesses a strong anti-interference ability, practicability, stability, safety and environmental protection.
