West Virginia, USA

At a site in West Virginia, a gas pipeline passes through a section of ground that exhibits instability and some minor sliding, which may adversely affect the operation of the pipeline.

In order to assess the effects of potential ground movements, two locations along the pipeline were instrumented with three Model 4150 Spot Weldable Vibrating Wire Strain Gages. Each location has a group of strain gages attached to the pipe at the 9 o’clock, 12 o’clock and 3 o’clock positions to determine the magnitude and direction of any resultant tensile and compressive strains.

The gages were spot welded to the bare pipe after the protective covering was removed. The instrumented section was covered with a waterproofing material, and then wrapped with special tapes to further prevent moisture ingress that might cause corrosion of the pipeline.

The cables from each gage were routed to a 16-channel datalogger, located above the pipeline, which was configured to read the gages on a daily basis.
