Oskar Santesson explains:
- We had an excellent dialogue with Bäckman before the decision. Together, we thoroughly and systematically reviewed the pros and cons of the two alternatives.
The machine was dismantled, transported to the workshop in Filipstad, where parts were renovated or replaced with new components. Before reinstallation, the remaining parts were cleaned, repainted, the air connections were replaced, and all electrical connections were renovated.
Mika Ström, responsible technical salesperson:
- Even if the customer is determined that a new facility is needed, we always consider the possibility of a renovation as in this case. Despite the dismantling and reassembly, it turned out to be the best solution in terms of both economy and time. The entire project was completed in a total of eight weeks.
The shot blasting machine is used to clean loosely adhering surface rust on pipes used in Valmet's production of new spare parts components.
Oskar Santesson adds:
- We expect the machine to last for more than 20 years, largely thanks to the service agreement we have with Bäckman, which includes annual preventive maintenance of the machine.
Valmet Energy Sales & Service Operations' customers are pulp mills in Europe and South America. The mills' recovery boilers, which burn concentrated black liquor or thick liquor and produce superheated steam, are equipped with steel tubes containing water that reach high temperatures. Safety is high around these boilers, requiring regular inspections. During these inspections, any defects in the boiler tubes are identified.
