Let’s talk about 3-D’s Stress Concentration Tomography (SCT) Services.

What is Stress Concentration Tomography (SCT)?

SCT is a passive magnetic sensing tool that collects the magnetic data of a target pipeline and then analyzes it for self magnetic-flux leakages in the pipeline wall, which are know as Stress Concentration Zones(SCZs). Using this stress-profile information, integrity managers can make informed decisions regarding the safe operation of their pipelines.

What does SCT Identify?

SCT™ identifies the location and the estimated stress of each SCZ (Stress Concentration Zone) on a pipeline.  An SCZ is an accumulation of localized stress in the pipeline wall that is greater than the nominal hoop stress of the pipe.  SCZs are caused by corrosion, metallurgical defects resulting in wall thickness loss and mechanical sources such as twisting and sagging from poor support and ground movements.  In turn, the increased localized stress within an SCZ prompts a localized realignment of magnetic domains which appear as an anomaly in the background magnetic field.

SCT™ identifies the particular magnetic signatures associated with different types of localized stress in the pipe and can differentiate between unexpected changes in stress caused by, for example, corrosion and expected changes in stress caused by girth welds.  After mathematical processing, localized stress increase, no matter what the source, generates the same waveform and SCT™’s automated search algorithms can identify their locations to cm accuracy.  Algorithms also have been developed and trained to examine the characteristics of each magnetic signal within the SCZ to estimate the quantity of stress causing them.  Significantly this is done directly through analysis of magnetic data without any intermediary analyses of wall thickness loss calculations, any need to excavate, calibrate, verify or alter the pipeline in any way prior to or after inspection.

NEW SERVICE: Stress Concentration Tomography (SCT)

3-D Line Locating Ltd. is pleased to formally announce our most recent, valued added service to our clients and other individuals and/or oil & gas companies that will benefit from this technology:

Stress Concentration Tomography (SCT). 

Above-ground, In-Situ, Non-destructive pipeline inspection Service for Oil & Gas Pipelines

Please visit our website HERE for more information on SCT, what it is, how it works and can benefit an array of individuals and oil & gas companies.

Make sure to download the SCT Brochure on our website while you’re there.

We are finalizing our “demonstration area” at our head office in Nisku, AB and will be inviting everyone to come out soon to see this new technology in action!

If you are interested in learning more please contact us directly. We can send brochures, have a lengthy phone call or the best option; why not have us come to you and put on our presentation for SCT!

Our Clients Asked! –All About Our Integrity Management Distributed Fiber Optic Sensing

Integrity Management

Pipeline Under Contruction

Protecting your people, the environment and assets is a top priority for all companies.  At 3-D we provide Integrity Management Solutions for our clients to help them manage their assets by reducing the risk of structural failures on critical infrastructure projects.  This includes the Pipeline, Oil & Gas, Industrial Plant, Tailings Ponds, and Power Line industries. Integrity Management helps ensure our clients can attain full operational quality from their equipment by the maximizing a project’s lifespan.  Our solutions are proven and assist our clients in realizing full value on their investments.

Our pipeline integrity management program implements fibre-optic sensors which provide high resolution measurements that can detect small leaks, subsidence, deformations, and/or other movements or failures. They monitor the health of the structures and materials of pipelines, tank farms, tailings ponds and many other infrastructure in real time 24/7/365. The key is to identify issues when they are small – before they produce a catastrophic result for the owner and the public.

Providing Integrity Management solutions has been a natural progression for 3-D.  Our history has seen us provide more than two decades of underground line locating services on major pipeline, oil & gas, and transportation infrastructure projects.  In this role, we provide ground disturbance services allowing the construction to proceed safely.

With the move to providing Integrity Management Solutions, we are now able to assist our clients during the operation of these same projects.  Integrity Management further extends our partnerships with our valued clients through all stages of construction, operations and decommissioning.  This collaboration benefits many including company shareholders and management, local communities, the government, the public at large and the environment.

Integrity Management include Leak Detection, Plant Sites & Tank Farms MonitoringSubsidence Monitoring, and  Tailings Ponds.
