METHOD AND DEVICE FOR SAMPLING PRESSURE BARRIER OF FLEXIBLE PIPES

The present invention proposes a split clamp (7), typical of trepanning operations in pipes, which allows the intervention with a tool (3) that makes a circular hole in the pipe (1) under analysis, removing layer by layer, until reaching the pressure barrier (2). With this, a sample of the layer of...

More Information
Summary:The present invention proposes a split clamp (7), typical of trepanning operations in pipes, which allows the intervention with a tool (3) that makes a circular hole in the pipe (1) under analysis, removing layer by layer, until reaching the pressure barrier (2). With this, a sample of the layer of interest is removed to be forwarded for analysis. Such a clamp (7) has means to isolate the pipe (1) from the external environment, introduce the tool (3) and remove the same with the sample, also allowing tightness repair of the pipe (1).
