Thanks in advance

The Iso shows no fitting so the designer thinks it can be bent from a straight piece of pipe on site. Remember - More details = better answers Also: If you get a response it's polite to respond to it. Upvote 0 Downvote

There are limits on both of these. = = = = = = = = = = = = = = = = = = = = P.E. Metallurgy, consulting work welcomed Upvote 0 Downvote
