Is it a requirement of the Power Piping code to have
ht numbers applied to all pieces of pipe/tube in a
piping system when the heat numbers are known. Situation
arises where several small pieces of pipe/tube are cut
to fabricate the system, however not all would have
the ht# unless reapplied by fabricators.
