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 tiny ‘cleaning lanes’ on the shell side 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. Using remote micro technology that travels the full length of all the cleaning lanes and channels, penetrating to where the scale is and also removing any 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.

I believe [Tube Tech’s] technology and know-how is sound, and that its track record in specialist service delivery is second to none in this frontier technology field of on-line specialist cleaning. Its technology and know-how also extends to OEM design considerations for more effective and “built-in” cleaning techniques from the outset.

The overall result that Tube Tech is able to deliver for customers in the hydrocarbons business is a more reliable operation, less down-time, faster turnarounds, and ultimately a lower total cost of operation.

I am impressed with its knack for developing technology in this field, and its strong customer loyalty/track record.
