Piping test header requirements 1

[albaweld]

Under B31.3, are there any requirements in regards to design or registration governing the fabrication of a hydro-testing manifold.
Thanks for the time spent on this.

Not in th USA. Just follow B31.3, and any applicable in-house pipe specification. If your manifopld will conflict with your 'house spec', write & *sign* an exception to that spec, giving the design criteria you followed. A manifold is just more pipe.
