Tube and Shell Side Cleaning of TWISTED TUBE Heat Exchanger
Once perceived as difficult to clean TWISTED TUBE Heat Exchanger by Koch Heat Transfer Company are favoured for more challenging heat exchange services like hot crude oil versus viscous hot vacuum residue and for services where high thermal coefficients and mitigated fouling are attractive.
TWISTED TUBE Heat Exchangers typically have 40% higher heat transfer coefficient for the same pressure drop as conventional shell & tube heat exchangers. TWISTED TUBE Heat Exchangers are self-supporting so baffles are not required. There is less vibration as tubes are supported at multiple contact points and the reduction in turbulence means no dead spots with the hope fouling will be reduced.
Shell side fouling and tube side deposits are often difficult to remove using either traditional high pressure water jetting or chemicals. These exchangers contain ‘cleaning lanes’ but if these become blocked with deposits the twisted tube heat exchanger becomes a challenge to clean.
Tube Tech offers an advanced bespoke cleaning technique for shell side cleaning. Tube Tech uses remote technology that travels the full length of all the cleaning lanes and channels, penetrating the scale and also removing all blockages from deep within the tube bundles. Cleaning of the internally twisted tube bore is performed using a technology that expands during cleaning, to the given diameter and tube twist configuration.
