GTI Reports Progress In Developing Tow-Tension Monitoring/Data Logging Tool

摘要

A tow-tension monitoring tool (TTMT) is being developed by Gas Technology Institute (GTI). Developers seek to provide a means of directly monitoring and date-time logging the tensile load on PE pipe as it is pulled underground during HDD installations. The work is sponsored by GTI and KeySpan Energy. Developers expect to help prevent instances where PE pipe is overstressed or breaks when the tensile load exceeds the safe maximum limits. The logging capability will allow a utility company to have an archived record that documents proper pipe installation. This is important to prevent cases where the pipe fails prematurely at some future date due to improper installation even though it did not break during installation. The TTMT is a new technology. The device takes a live reading of the load and transmits the information to a receiver at the drill rig. In addition, the information is logged into memory with a time/date stamp for an archived record of the events.
