Paragraph 6.2 imposes a maximum limit of 3 longitudinal weld seams for tubular products 16" and larger. Paragraph 1.2 states "Tubular products having other diameters or wall thickness, or both, may be furnished provided it complies with all other requirements of this specification."
Although diameters up to 54" can be manufactured with 3 longitudinal seams, some end users require larger diameter A778 pipe.
This revision would impose a limit of 3 longitudinal weld seams up to 48", and a maximum of 5 longitudinal weld seams above 48".
