Challenge N°4

Optimise the inspection of buried casing pipes and/or the detection of non-visible defects

Discover

GRTgaz wishes to review its practices and is seeking innovative solutions for optimising the inspection of its pipes in restricted environments enabling it to check more simply certain points which are difficult to access because they are buried (inspection of casing pipes and sleeves), or which are difficult to view because they are incorporated into other facilities (passage through concrete walls, above-ground supports or thermal-insulation). Two use cases are specifically identified:

 

– Recording of the thickness of the pipe passing through the casing pipes (steel or concrete), and inspection of the annular space;

 

– Detection and quantification of non-visible metal defects on the pipes

Challenge N°4 – A

Recording of the thickness of casing pipes and sleeves (steel, concrete or PVC), of the gas facility contained in them, and inspection of the latter and of the annular space

Challenge N°4 – B

Detection and quantification of non-visible metal defects
