Performance qualification to AWS D1.2. Testing on 6" sch 40 (.280" wall) 6061 groove weld, for a cyclically loaded application. Table 3.8 number 3 (cyclically loaded tubular structures) calls out 4 different pipe sizes for this test, of which 6" sch 40 is not listed. So I then go to Table 3.8 number 4 (job size pipe or tubing), which directs me to remove 4 side bends, for any wall thickness on pipes greater than 4" nominal. Typically you would expect to remove face and root bends for a 6" sch 40, yet this Table clearly states side bends. Any thoughts on this?
