Date Issued: May 24, 1988
File: B31-87-039
Question: In accordance with ASME/ANSI B31.3, are there requirements or guidelines on the minimum distance between welds in a pipe?
Reply: No, except as provided in para. 304.3.3(e).
Interpretation 25-20
Subject: B31.3-2012, Interpretation of Figs. 328.5.4D Acceptable Details for Branch Attachment Welds

File: 14-1470
Question 6: Does ASME B31.3 provide any rules or restrictions or limits for the distance between circumferential butt welds in a piping assembly?
