Sorry, I couldn't understand your query properly.
I guess, you would like to know the joint efficiency difference of seamless as well as welded section of metallic hollow cylinder section supposed to use in pressure container application.It depends upon the extent of NDT methods used to find volumetric defects as per design of the welded hollow cylinder or seamless hollow cylinder to meet the quality requirements of the end user.
Magnifying lense can be used for close inspection and verification to rule out seamed or seamless. Riveted joints are not quite common in these days, which are easily identifiable with naked eyes.
