Pipeline Integrity – Area Monitoring

Overview Operator performed ILI screening for first time since the pipeline had been constructed (7 years prior) and found a 3 feet section of pipe which saw >25% wall loss at 6:00 position. Operator cut out the pipe section and sent to lab for microbiology lab for evaluation. The individual welded in a new pipe

Pipeline New Construction

Overview An operator found internal corrosion during an ILI run and decided the pitting required a segment of the pipe needed to be replaced. 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

Pipeline Integrity – Liquid Line

Overview Operator performed ILI using a smart pig to inspect a segment of their crude oil pipeline. The ILI report showed a number of pits which were not present the last time the ILI was completed. The operator wanted to know if the pits were episodic in nature or were growing (and if so, at
