Client: Textile Company

Job: Full Re-Tube of Wellman-Robey 12,000lbs/Hr Steam Boiler

Scope of Work

Due to poor water treatment over a number of years, the condition of the boiler tubes had deteriorated to such an extent that tubes had to be repaired on numerous occasions. The decision was made during a two week shut down in the summer that a full retube of the boiler would take place.

McEwen Boilermakers attended site on the pre-arranged date and carried out the following:

  • J-Prepped Combustion Chamber to remove seal welds
  • Cut out old tubes, leaving stay tubes in place.
  • Prepared tube holes for new tubes
  • Slid new tubes into place and power expanded
  • Seal Welded tube ends in combustion chamber
  • Carried out hydraulic test for insurance inspector
  • Boxed boiler back up and brought up to working pressure
  • Handed boiler back to engineering staff.

The full re-tube took less than two weeks and the works engineer was delighted with the work.
