TOPIC: BPV Section VIII Div 1 – Data Reports for Weld Metal Overlay Cladding

    ————–

A pressure retaining part (e.g., tubesheet) is to be weld metal overlay clad (clad) by a subcontractor for supply to a Manufacturer. The thickness of the cladding may or may not be included in the design calculations, and the clad part does not fall within the scope of UG-11 because rules for the design and fabrication of the pressure retaining part are provided in Section VIII, Division 1.

Question 1: Does the Code permit the clad part to be supplied by a subcontractor who holds a Certificate of Authorization?

Yes, see UG-120(c).

Question 2: Does the Code permit the clad part to be supplied by a subcontractor who does not hold a Certificate of Authorization?

No, see UW-26(d).
