Eddy current flaw testing unit PROVEA has delivered a complete eddy current flaw testing solution to Cofrend Nord, a non-destructive testing official training and certification company.

linked so that the entry and exit speeds are exactly the same. The guidance has also been designed in order to ensure a repeatable and suitable position of the tube. The general manager of the NDT training unit has been very satisfied with the investment, and has increased training and exam capacity, which was necessary in order to meet market demand.

capacity: OD 10 to 90mm. Provea integrated on the bench the eddy current unit supplied by Foerster France (Defectotest – M90 Sensor System). The bench is composed of a feeding conveyor, two centring guiding pinch rolls, a central frame for the eddy current magnetising yoke, and an exit conveying system. The eddy current unit can be set in two main directions (axis Y and Z), allowing non-destructive experts to accurately find the best mechanical positioning of the tube compared to the eddy current measuring unit. Operators can be taught on a bench very similar to the industrial process of any tube manufacturer. The two pinch rolls are mechanically

This new bench, installed in the north of France, will be used in order to train and test future non-destructive experts, and enables the Cofrend group to respond to the growing demand for NDT training sessions in the tube industry. The eddy current bench has been designed by Provea similarly to purely industrial eddy current flaw testing machines. Operators will be trained on a machine similar to the industrial application they can face in their own production facilities. Compared to the old system, the new bench has more

New thread tables BRANDT Engineered Products Ltd has designed and delivered pipe handling equipment known as Thread Tables to a number of tube and pipe producers. Brandt Thread Tables integrate with the most modern machine tools. These machine tools are big bore lathes, often called ‘threaders’, and are used to produce both API and premium threads on tube and pipe.

The new design is meant to eliminate costly repairs caused when pipes bump the machine tool upon entry.

Powerful Pipe Benders

Brandt equipment positions material in and out of the threaders quickly, keeping up with the improved cycle times offered by the latest machine tool suppliers. Maintaining cycle times with threaders is a critical variable to ensure the investment in the machine tool achieves maximum return. The Brandt Thread Table utilises adjustable stops to position one pipe at a time on the table. The table is designed with four independent idler rolls used to absorb vibration while the pipe is spinning during the threading process. The independent idler rolls were engineered and manufactured to reduce unwanted pipe movement at multiple locations along its length. This dampens the whipping motion of pipe, allowing the machine tool to produce API and premium threads on the end of each pipe with greater confidence. Pinch rolls are used at the head of the Thread Table to protect the machine tool, while elevating V-rolls enable various diameter pipes to be fed into the machine tool at the proper elevation.
