ABSTRACT:
A tower for drying the inner diameter of elongated tubes includes a plurality of endless synchronously driven pintle conveyors having vertically ascending and descending support paths for the tubes and an air manifold system operative to force heated air at controlled velocity through the pipes in one direction during ascent and to force heated air at increased controlled velocity through the pipes in the opposite direction during descent. The endless conveyors are supported by a plurality of spaced tower frames, with the two end tower frames having air ducts of the manifold system connected thereto, one of said end tower frames and the air duct carried thereby being movable relative to the other tower frames to permit tubes of varying lengths to be conveyed and dried.
