Cased Pipeline Inspection and Monitoring By Profile Technologies

Overview

Cased pipe is usually a buried system composed of a coated or wrapped carrier pipe that is evenly suspended within in a larger diameter pipe (casing). These systems are designed to provide structural protection against carrier pipe damage, ruptures and external corrosion. They also, however, present a real challenge to those charged with monitoring their integrity.

Corrosion conditions can develop within the cased pipe environment that can negatively affect the carrier pipe's integrity. Anomalies caused by external corrosion are difficult to predict and identify on pipe inside casings and are becoming increasingly common in aging pipeline systems.

Companies that are focused on protecting people, the environment, and profitability, actively pursue a regulatory compliant program that identifies corrosion

 

Profile Technologies' EMW-C™ technology is ideal for identifying pre-corrosion and corrosion conditions in cased pipe systems:

1. Electromagnetic waves are launched into the annular space between the casing and carrier pipe.

2. Reflections from anomalous conditions such as water, corrosion, pipe-to-casing shorts and foreign materials show up as specific reflection curves in the processed data.

3. Anomalies are identified and located along the length of the cased region.

4. Depending upon the system configuration, Profile can normally inspect an entire casing in 90 minutes and several casings per day.

5. Finally, above-ground leads are installed to permanent pipe and casing connectors so that all future regulatory required monitoring can be accomplished without excavation.

 

About Profile Technologies

Profile Technologies, Inc. was incorporated in 1986 and commenced operations in fiscal year 1988. The Company is in the business of inspecting pipelines for corrosion and other anomalies that require inspection to verify pipeline integrity. Profile has developed a patented, non-destructive and non-invasive, long range inspection process, using electromagnetic waves to remotely inspect buried, cased and insulated pipelines for corrosion. Profile’s services are available to owners and operators of natural gas and oil pipelines, power plants and refineries, utilities, and most any facility with cased or insulated pipe.
