    Currently building a 40.000 m3 crude tank

    I agree with JStephen and IFR about the code statement about, but as a constructor QA/QC, at least in our company, we do NDT in this type of installation, never the less, this is our company standard, not a code requirement, if it's an exigence of the client I think that they should bargain with...

    tanks accesories
