Abstract

A helical or spiral turbulence insert constructed from a twisted strip and for loose insertion into the circular cross section tubes of a flow through type heat exchanger without any form of joints to the tube wall. The strip in partic. for tubes of diameter 25 mm, such that the spiral diameter is 0.4 - 3% less than the tube diameter and the spiral thread pitch is some 2 - 5 times the spiral diameter with a strip thickness of 1.15%. The spiral diameter has, in addition to 2421519, a longitudinal reinforcement (2) incorporated or preformed into the strip material (1) before the spiral forming operation takes place.
