Robotic system for pipeline rehabilitation

US Patent 8,783,297

Applications

An application for this technology is in pipeline rehabilitation.

Problem Addressed

Leaks that occur within pipelines underground may not be as accessible using current technologies.

Technology

This invention presents the design of a robotic device for patching pipeline leaks. A stretchable curing patch is designed for the pipe which ensures that it fits perfectly within the pipe. The patch is driven by a robotic device which carries a camera and can be controlled wirelessly. The curing patch can be designed to fit both circular and non-circular pipe geometry.

Advantages

  • Fixing the pipeline from the inside is a more secure solution for pipeline leakage.
  • The whole process is robotic which can be controlled wirelessly.
