Case Study
The Most Precise Pinhole and Pitting Services

Following the initial dig verification program, NDT Global worked alongside the operator to create a new set of requirements focusing on the accurate sizing of pittings and pinholes.

Case Study
Hydrostatic Testing for Complex Cracking

To address tilted (hooked) and skewed cracks, a modified sensor arrangement was introduced to the fleet of tools.

Case Study
Evaluation of Cracks in a Petroleum Pipeline

Engineers from NDT Global carried out extensive investigations to gain visibility into overall pipeline integrity.

Case Study
Girth Weld Cracking Threats in a CRA-Cladded Gas Pipeline

To inspect a 16" gas pipeline, we prepared a project plan to facilitate the inspection which included pipeline preparation, inspection run and a re-establishment procedure.

Case Study
Complex Crack Detection

An NDT Global field verification expert worked closely with the crew and conducted phased array UT to enhance the understanding of the crack geometries and provided crack depths.

Case Study
Long-Seam Pipeline Crack Inspection in Liquid Propane

After careful evaluation of its options for inspecting the 61.78 mile line, the operator chose NDT Global’s Evo Series 1.0 ultrasonic crack inspection tool.

Case Study
Verifying Emerging Pipeline Cracking Threats Using Ultrasonic Technology

NDT Global utilized a 12" inspection tool which has inspected more than 2,600 km (1,616 miles) in a circumferential configuration.

Case Study
Custom-Engineered Offshore Solution for BP

After a review of requirements an advanced ultrasonic tool was selected to accurately measure wall thickness and metal loss.

Case Study
Inspecting a Dual-Diameter Pipeline in a Single Run

Both the pipeline operator and inspection engineers worked hand in hand to design, build, and test a multi-diameter ultrasonic tool to fulfill these specific requirements.

Case Study
Simultaneous Crack and Metal Loss Inspection

A combination of high-resolution technologies were used to successfully detect metal loss and crack-like features in one run.

Case Study
Custom Engineered Baseline ILI for Multi-Diameter Export Route

We worked with an operator to launch an intensive development program focusing specifically on safe passage, while maximizing measurement accuracy.

Case Study
Delivering Precision by Combining FEA's with ILI's

SONACOL worked with NDT Global to perform an FEA, a method that is optimized to provide operators with an accurate estimation of pressure behaviors.

Case Study
Equinor: Custom Solution for an Extreme Subsea Pipeline

NDT Global performed the inspection run using high-resolution pinhole and pitting ultrasonic metal loss inspection technology.

Case Study
Ultrasonic Inline Inspection for Ethanol Pipelines

Following further investigations, to successfully begin the ILI process, NDT Global’s team proposed an ultrasonic wall thickness measurement inspection.

Case Study
Enhanced Identification without Compromise

To ensure the operator’s exacting resolution requirements were achieved, NDT Global separately utilized its UT crack and corrosion tools that both deliver the highest resolution measurements available.
