Yeah, since they use so much bamboo, it might be feasible to grade the pipes by thickness and/or some other objective measure of strength. Heck, they probably already do, informally.
As for imperfections, the bamboo masters seem to know how to (over)compensate for them, i.e. they build the scaffolding to withstand several times the expected load. As would any good engineer.
