Wisconsin Pressure Test Monitoring

At a glance

PipeSense monitored a 32,688 ft section of 4 inch pipeline during hydrostatic testing up to 1,840 psi. A pressure drop during testing was traced to a preexisting branch line leak connected to the plant, identified using pressure data alone.

Challenges

The project required monitoring fill, pressure up, and two hold phases under high test pressures. No pig was used during fill, limiting the ability for early detection. A pressure drop observed during testing required rapid analysis to determine the source.

Solution

PipeSense provided real-time monitoring throughout fill, pressure up, and hold phases. Pressure data analysis isolated the issue to an unidentified branch line leaking into a plant, with the location determined using pressure data without pig tracking.

Benefits

Verified Leak Location
Pressure data alone was used to identify and locate a preexisting branch line leak within the test section.

Increased Test Confidence
Real-time monitoring ensured that pressure deviations were analyzed immediately, reducing uncertainty during critical test phases.

Data-Driven Insight
Clear pressure trends provided defensible, documented evidence to support findings and guide corrective action.
