Identify the exchanger before describing the fouling
Record the unit, exchanger type, bundle or pass reference and which covers can be removed. A drawing or current tubesheet photograph helps the cleaning company understand orientation and access. Performance data, samples and previous tube findings are then attached to that identified equipment. The heat exchanger cleaning brief can then connect fouling evidence to the correct bundle.
Operating history, access and fouling evidence
- Equipment reference, exchanger type and tube arrangement.
- Process and service fluids, with known deposit information.
- Which tubesheets and covers can be opened.
- Isolation, opening and the time available for cleaning.
The brief used to prepare the cleaning visit
Give the exchanger and bundle reference. Attach drawings or data that show passes, tubes and openings. Describe fouling and recent performance. Add symptoms, previous findings and any available samples or photographs.
Record when the bundle is open and when inspection needs it. The brief should also state how cleaned and restricted tubes will appear in the tube record.
Send the brief when enquiring about heat exchanger tube cleaning. For symptoms that still need separating from the cleaning method, see fouled heat exchangers. We will review the gaps with you before a final quotation is set.
Using the heat exchanger cleaning brief
- Do I need the original exchanger drawing? It helps, but current photographs, pass arrangement and measured access may be enough to begin the review.
- What if the fouling is unknown until opening? State that uncertainty and include history from earlier cleans. The job details may need a decision point after the bundle is exposed.
- Should the inspection team see the brief? Yes. Their acceptance method and timing should align with the cleaning completion check rather than being decided separately.
