Despite the fact we are only a small player in the world of Non Destructive Testing, we listen and act on the customer and the market. We strive to create solutions for issues and customerproblems.

Dented pipes
During a test in Belgium we were confronted with a new challenge concerning support points.
Because of the weight, the 12" pipe had been dented at the point where the pipe meets the bar.
After raising the pipeline it turned out there was no corrosion present.
During the testing in circumferential direction the signal clearly indicated heavy corrosion to be present. That was not the case.
During the testing of the exact same point in longitudinal direction, the signal indicated that there was no corrosion present.
In the newsletter of April last year, we have reported that there is a difference with testing in longitudinal or circumferential direction. For this cause multiple tools have been developed.
By testing we are able to tell the difference between dented pipes and corrosion.
 

     
Tool for trunnions welded on elbows

Recently we received the question from the UK whether it was possible to test trunnions welded on elbows from 2" diameters. For straight pipelines we are already able to offer this tool. Now, we have developed a tool which makes it possible to test as well as from the outer radius as the inner radius from 2" diameters and upwards.

 

     
Tool for testing pipelines fitted with clamps

Many small piping is fitted with clamps. Until now these were removed before testing which implicates extra costs. With the tool we have developed these clamps do not need to be removed any more. The tool is able to test from 2" diameters.

 
     
Support point testing using rope acces

At a big refinery in the Netherlands we have been testing jetties/piers with the help of a company specialized in rope access. Although the height makes it work a bit different to testing in a field, the results turned out to be similar as normal UT-testing.

 
     
Investigation for level of slug in pipeline

In 2014 our customer in Brunei send us the question if it was possible to find the level of slug/sand in a 10 inch pipe filled with water and oil. Although this is not our core business, we did manage to indicate the level of solid material and liquid. We prepared a pipeline filled with sand, oil and water and using 2 probes, we performed the test. As can been seen in the pictures, there is a difference in signal when reaching the slug.
