Abstract
A tube support includes at least two parallel plates. With more than two plates, the outer plates are longer in the direction of flow than the inner plates. Pins are provided proximate the leading and trailing edges of the plates in order to maintain the plates in a spaced relationship. The pins proximate each edge are positioned slightly over two tube diameters from the other pins along the same edge. Additionally, the pins along the trailing edge are positioned approximately one tube diameter from the pins proximate the leading edge in a direction along the edge in order to stagger the leading and trailing pins.
