Many heat exchange upgraded systems have at the same time been produced for the change of
vitality utilization, material sparing, measure lessening and pumping power decrease. Sink tape embeds
tubes are a common procedure that offers a higher heat exchange increment and, in the meantime, just a
mellow weight drop punishment. This examination researches the heat exchange qualities of a flat tubein-
tube heat exchanger having inner strung pipe with various pitches. Heat exchange, stream erosion
attributes in a strung tube fitted with screw tape, utilizing oil as working liquid are examined tentatively.
