Spiral magnetic flux leakage inspection tool

In 2010, T.D. Williamson, Inc. (TDW) announced the debut of its patent pending Spiral Magnetic Flux Leakage (SMFL) inspection tool, the latest addition to its range of magnetic flux leakage inspection tools.    

According to TDW, combined MFL and TFI capabilities offer unprecedented detection capability. Whereas traditional axial MFL technology detects volumetric pipeline anomalies, general corrosion and wide circumferential flaws, the new SMFL tool makes it possible to detect long, narrow defects in a pipe body and in long seam welds. Transverse field inspection (TFI) tools are designed to detect general corrosion, as well as long and narrow metal loss features.    

“By combining the capabilities of the standard TFI tool with those of a conventional axial MFL system, the new SMFL tool fills a niche in the market for a system that combines inspection technologies,” said Enzo Dellesite, General Manager -  Middle East Operations for TDW.    “By doing so, operators can detect and characterize a much wider range of pipeline defects that simply was not possible until now,” he added.  

The high resolution SMFL tool offers a number of benefits.  For example, while TFI technology relies upon two magnetizers, the SMFL tool requires only one.  As a result, the SMFL tool can be paired with MFL technology without having to extend the length of the tool to accommodate it.  The ability to pair tools means that multiple datasets are generated in a single run.  

TDW uses these datasets by overlaying them, which greatly enhances characterization of anomalies that are revealed during an inspection run.     For example, recently TDW ran separate runs with each system in a 16-inch pipe with a .250 wall thickness.  While the axial MFL tool did not detect an external axial gouge, data generated by the SMFL tool revealed an external gouge measuring six inches long x .25-inch wide x 40% deep.  

With a sampling frequency of up to 750 samples per second, the SMFL tool has an operating pressure range of 300 to 2,000 psi (21 to 137.8 bar) and an in-line temperature range of 14 to 131°F (-10° to 55°C.)  It has a minimum bend radius of 1.5D and can travel at up to 8.3 ft/second, making it an extremely adaptable and efficient inspection system.  

The addition of the SMFL tool further extends TDW’s comprehensive pipeline inspection services, which features the recently launched 48-inch Gas Magnetic Flux Leakage (GMFL) inspection tool.  This tool operates at a steady speed in spite of variations in gas pressure that tend to cause other tools to stall and surge as they move through a gas line.

Minister Rickford: New Oil Pipeline Projects Mark Significant Milestone in Canada's Contribution to Energy Security

The Honourable Greg Rickford, Canada's Minister of Natural Resources, has delivered remarks during a ceremony in Freeport, Texas, marking the completion of the Seaway and Flanagan South Pipelines. Minister Rickford attended the ceremony with Jim Prentice, Premier of Alberta.

Minister Rickford highlighted the importance of working together to enhance North American energy security and its benefits for our respective economies and global competitiveness. These pipelines will have the ability to move approximately 600,000 barrels per day into the Gulf coast, from Alberta, Saskatchewan, Manitoba, North Dakota and Montana.

Mcelroy Announces New Hydraulically Adjustable Pipe Stand

McElroy has brought hydraulic capability to its Pipe Stand line for 4” to 20” (200mm-500mm) pipe to help align thermoplastic pipe more efficiently on butt fusion jobsites.

The Hydraulically Adjustable Pipe Stand features hand-pumped hydraulic lifting which gives the operator the ability to adjust the height of the stand while the pipe is still supported on the stand. The hydraulic adjusting feature eliminates the need to remove the pipe from the stand so that the chain and height can be adjusted by hand.

Proper Purge Processes Ensure High Quality Pipeline Joints

Joints of high quality between cylindrical sections such as tubes and pipes can only be made by ensuring that atmospheric gases are eliminated, and positive, smooth weld reinforcement is provided.

The presence of oxygen, and to a lesser extent nitrogen, around the molten weld can lead to wide-ranging defects. Discoloration is unsightly and in some instances might reflect metallurgical imbalance, especially with some stainless steels. Gross oxidation inevitably results in reduction in mechanical properties and can cause catastrophic loss of corrosion resistance. Nitrogen contamination can result in brittleness. Gases in the weld may give rise to cracking during or after cooling.

Automated Removal of Black Powder Extends Pipeline Life

An example of black powder removed during one week of operation.

Black Powder (BP) is an abrasive contaminant (iron oxides and sulphides) present in all gas and hydrocarbon fluid transmission lines. BP is primarily the result of moisture which causes bacterial and chemical corrosion of the carbon steel walls within pipelines and containment tanks.

BP acts like sandpaper, wearing the pipe wall. This results in more black powder particles ranging from 100+ microns to sub-micron in size. The majority of BP is under a micron.
