Reply to "GT5 flare installation durability question?"

I know the answer :

Clearify for me whats meant by BUTT WELD and whats a LAPP JOINT ... it appears to me the LAPP joint is what we are all using here and clearly stronger. You have metal overlapping for strength

A BUTT joint and depends exclusively on the weld .. and requires a FULL weld joint consistantly with full penetration and the length of the joint. Too brittle on sheetmetal to be strong .. But joint is strong in pipe welding with 2 -3 different ROD.

It looks like we are doing LAPP joints with 100's of tack welds ???
