[MW:23227] RE: 23220] Eddy Current vs Hydrotest for LTCS pipes (A333 Gr.6)

I have now looked at ASTM A 333 and see that eddy current testing is permitted as an alternative to hydrostatic testing under this standard. It goes to show – if all else fails read the specification!

No. Eddy current test is a surface inspection technique – technically an alternative to MPI.

Hi All,

 

Mill performed ET for 1.5" Sch160 Smls Pipe A333 Gr.6.

Is ET acceptable in lieu of hydrotest? if yes, is there any limitation criteria?

Thanks.

 

Regards,

Eric.C
