Overview Customer built new unit to increase production. H2S line prone to corrosion at two different 90s before overhead line. Elected to use non-intrusive permanently installed UT sensors to monitor pipe intrados, extrados, top & bottom locations in lieu of installing a heat trace to maintain dew point. Application Vacuum Fractionator ~300F 12” Sch. 40 […]

Hydro-Fluoric (HF) Alky Unit Monitoring

Overview Customer was sending NDT technicians to inspect the top of the HF Alky unit daily to monitor specific low spots to ensure wall loss did not exceed minimum required rate before outage planned in 6 mo. Now using system to correlate corrosion data to integrity operating windows (IOWs). Application HF Alky Unit (HF Isostripper […]

The location of the localized corrosion was unexpected and concerning with the severity of the pitting so the operator decided to monitor the same area on the new pipe where the […]

Pipeline Corrosion Monitoring

Overview Customer installed new pipeline to feed untreated water to their refinery instead of treated water which would save approximately $600,000,000 per month. 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. Application […]

Pipeline Integrity – Gas Line

Overview An ILI report showed a number of low spots at three separate locations along a 100 feet stretch of gas pipeline. When the previous ILI was performed 7 years prior, these low spots did not exist. The operator not only wanted data to tell if the corrosion was episodic or in nature or active […]
