Both ends of each double-welded pipe shall be visually examined to determine that complete fusion is attained between the two welds. Tension tests shall be made on specimens from two tubes for lots of more than 100 pipes, and one tension test shall be made on a specimen for lots of not more than 100 pipes, Also, for material heat treated in a batch type-furnace, flattening tests shall be made on 5 % of the pipe from each heat-treated lot.
