Customer installed new pipeline to feed untreated water to their refinery instead of treated water which would save ~$600K/mo. The new pipeline needed to be monitored in the areas where the pipe was internally uncoated next to welded joints. Each of the 16 points were then environmentally sealed and buried.


Four weld joints each w/ 4 sensors placed 2:00, 5:00, 7:00, & 11:00 and then buried

  • 36” sch. 10 pipe, <100F
  • Locations scattered along 50’ of excavated pipe
