Bottom domes in pressure vessels like pulp digesters (both continous and batch digesters), impregnation vessels, columns and reactors often suffers from two degrading mechanisms related the actual process parameters. Erosion or Corrosion. Sometimes both degrading mechanisms are present. The Uddcomb techology is developed to solve these degrading issues of components. The Uddcomb technology makes it possible to avoid a very costly, time consuming and technically challenging replacement of a new component and instead being able to repair and refurbish the actual component onsite – anywhere in the world.
Bottom domes in pressure vessels like pulp digesters (both continous and batch digesters) and impregnation vessels often suffers from two degrading mechanisms. Erosion and corrosion. In both cases action will be required before the pressure vessel are below minimum thickness. Replace the complete pressure vessel or the local section to a new one, or repair the actual pressure vessel.
Uddcomb have developed a weld overlay refurbishment technology customized for bottom domes in pressure vessels.
1. No need for very costly investments in a new pressure vessels or a pressure vessel sections. 2. No need for a technically challenging and risky replacement project 3. No loss of valuable production related to a longer outage - The Uddcomb Method refurbishment project is finalized within the planned outage schedule.
