Paper Abstract

PLS International introduces its technology to visually examine the internal condition of in- service low pressure distribution piping. The PLS 3000* Enhanced Pipeline Inspection System has the capability to visually examine 3 inch to 8 inch cast iron, steel, and plastic in-service piping to distances to 1000 linear feet through a sealed removable access fitting. PLS proprietary pipe crawling robots are capable of examining 8 inch to 60 inch diameter piping to 2000 linear feet through sealed accesses from a single excavation. A summary of benefits to distribution companies by employing this technology is detailed. Actual color videotape and videophotographs are presented as documentation.
