Abstract (en)

[origin: EP1367350A1] A coil wound tubing assembly for use in a coil wound heat exchanger. The tubing assembly may comprise a first coil wound tubing bundle and a second coil wound tubing bundle, wherein one or more groups of tubes in the first coil wound tubing bundle may be connected in direct fluid flow communication with one or more groups of tubes in the second coil wound tubing bundle, characterized in that the first and the second coil wound tubing bundles differ in one or more parameters selected from a group including mandrel outer diameter, spacer thickness, number of spacers, number of tubes, tubing inner diameter, tubing outer diameter, tube length, tube pitch, and tube winding angle. <IMAGE>
