If the Clad is on CS/LAS To confirm complete removal of clad, apply Coper sulphate solution on this area . Surface turns redish , It confirms that there is no contamination of clad is left over

Subject: [MW:2864] cladding
Dear all
I have one query about cladding. In our GTL project slug catcher is going on with construction code of B31.8. We have one pipe line of material 1SO 3183-3 L450 MCS with 3mm inconel cladding. As per our method statement we should require minimum 5mm de- cladding from the bevel edge before fit-up with machining or grinding.
So my question is, how we conform or ensure that cladding material is removed or not?
Regards
M JavedÂ
