Mineral deposits removed prior to inspection
Having experienced Tube Tech’s successful cleaning of LNG condenser tubes on a Middle East LNG site this Asian LNG plant contracted Tube Tech for a specialist application on its own site. The tubes within three condensers were polished utilising Tube Tech’s innovative tailor made technology prior to the condensers being inspected, effectively, quickly and safely.
- Brass tubes to be cleaned to a high standard.
- The condensers had never been cleaned back to bare metal before.
- Tube surface to be polished to enable accurate IRIS inspection readings.
- Deposit was known to be hard and tenacious but thickness was unknown.
- Work scope to be completed within a short time frame.
- Tube Tech used their single flexsafe system to polish the tubes to a very high standard. This system had previously been used successfully on an LNG plant in the Middle East earlier in the year.
- The system is extremely safe as no high pressure water is used.
- This bespoke cleaning technology removes tenacious scale and polishes the internal tube surface in one action.
- All tubes were polished successfully within the time allocated by the client.
- The high standard of cleaning and polishing within the tube bore enabled a high degree of accurate IRIS inspection readings to be achieved.
