Hello,
I have an application where we are expanding tubes into a boxed header. The fluid through the tubes is natural gas. I have a couple of questions that hopefully someone can help. The header and tube circuits are designed to ASME SECTION VIII.
(1) For grooved header holes, what is the recommended groove design (depth, width)? Is there some industry or code standard that is commonly used?
(2) For natural gas applications, Section VIII requires that the expanded connection be given a seal weld. What size of seal weld is required. I couldn't find a requirement in the ASME code.
Thank you,
Alex
