Pipeline Services Data Sheet - Dexter Magnetic Technologies - #1

Pipeline Services

The magnet assemblies we have designed and manufactured are in operation worldwide on pipeline cleaning pigs, caliper pigs and non-destructive pipeline inspections pigs utilizing the magnetic flux leakage (MFL) principle. The relatively low operating temperatures of pipeline pigging allows for greater flexibility in the selection of magnet materials. Because of our expertise in magnetic design & applications, our typical inspection designs use Neodymium Iron Boron (Nd-Fe-B). Nd-Fe-B magnets are the strongest commercially available magnetic materials, both magnetically and structurally. They are also extremely resistant to demagnetization. For cleaning pigs, depending on their type and size, the application may call for any one of a variety of magnet materials, including Flexible Ferrite, Hard Ferrite or Nd-Fe-B.

We offer both the standard reusable Alnico horseshoe type magnet pipeline marker as well as our own lower cost marker assembly. You have told us it is not always convenient or cost effective and is sometimes even unsafe to spend the additional time and manpower retrieving pipeline marker magnets. As a result, our engineers have developed a lower cost marker assembly. The threaded holes in the top of our marker assembly provide you the option of mounting other components or accessories and the lower cost of the Dexter marker assembly make it more cost effective to use it and leave it.
