Hi,

Do you have Piping Catalog near to you? Can you give us the nearest upper schedule for this pipe?

My assumption is; Your pipe thickness must fall in the standard or practice. You may have calculated thickness with very economical selection but in the field, you need thicken it more so as to avoid failure with incidental loads. This issue is much concerned on small bore piping. But if you have 3” or more, then it’s another issue. These are just my opinion (My practices).

Regards,
