Re: [MW:14562] Difference in between ground smooth and ground flush jont

I assume ground flush is no weld reinforcement at all, smooth means only removing sharp edges / burs / irregularity of surface of welds.

 

 

UG-82 LUGS AND FITTING ATTACHMENTS

(a)

When pressure parts, such as saddle type nozzles, manhole frames, and reinforcement around openings, extend over pressure retaining welds, such welds shall be ground flush for the portion of the weld to be covered.

(b)

When nonpressure parts, such as lugs, brackets, and support legs and saddles, extend over pressure retaining welds, such welds shall be ground flush as described in (a) above, or such parts shall be notched or coped to clear those welds.

5-4 FABRICATION

5-4(c)

Longitudinal welds shall be ground flush and smooth on both the inside and outside surfaces prior to being formed into expansion elements.Also see

Mandatory Appendix 1, FIG. 1-6 (d) DISHED COVERS WITH BOLTING FLANGES , where

smooth weld is shown.

Dear All,

Please differentiate two terminology of ground smooth and ground flush in fabrication.

We are facing issue in this regards. Kindly give any back up supporting documents from where the definition is derived.
