Weld attachments

[FIF99]

Hi,

For adding welded support designs to thin wall piping we specify reinforcing pads on the piping before actually welding the supports to it. I do have some reference tables but:
Does anyone have a reference calculation method showing from which Diameter - wall thickness combination these pads are required?

Thanks in advance for any help.

Regards.

You have several different options;

1. Piping Handbook, Edited by: Nayyar, Mohinder L. © 2000; McGraw-Hill

2. MSS-SP58 (MSS SP58 - PIPE HANGERS & SUPPORTS - MATERIALS, DESIGN & MANUFACTURE).

I don't have access to either of these publications at the moment. I would expect that the Piping Handbook would be your best bet.
