Save money and time with proper maintenance

Maintainance of your shell and tube heat exchangers requires regular inspection and cleaning. The following steps are part of general maintenance and should be conducted on a regular schedule. 

  1. Frequent cleaning of heat exchangers
    Commercial cleaning compounds are used to remove sludge while coke is used if hot-wash, oil, or water washing do not provide satisfactory results.
  2. Tube inspection
    At regular intervals, inspect the interior and exterior of tubes and assess condition. Failure to keep all tubes clean may, in time, result in termination of flow, which can lead to tube leaks and ruptures.
  3. Fouling Assessment
    Exchangers subject to fouling should be monitored for a marked increase in pressure drop and/or reduction in thermal performance. Should these issues arise, a prompt cleaning is suggested; the greater the build up of scale, the more difficult cleaning becomes.
  4. Scraping
    If it is necessary to use scrapers to remove build-up, care must be exercised to ensure the blade is not sharp enough to cute the metal of the tubes. 

Proper handling when removing tube bundles for inspection or cleaning must be exercised to ensure the tube bundle is not damaged. Tubes are small and constructed of relatively thin material. Once removed, tube bundles should be properly supported with cradles located under the baffles.
