Stainless adds value for plant repairs and replacements

6月 26, 2015    
Around the world aging facilities are in constant need of repair and replacement. Stainless steel, with its corrosion resistance, is often a suitable replacement material. In addition, the sustainability of Outokumpu stainless steel offers added value.

Count the overall lifecycle ​​​cost

At the Managing Aging Plants Conference and Expo, Outokumpu presented the sustainability and life cycle cost benefits of its stainless steel. The presentation suggested that repair and replacement of aging plants should address total life cycle cost, which takes into consideration the material cost, initial costs (like welding, assembly and coating costs) along with future costs like repair, recoating, and loss of production.

“When all these factors are considered, stainless steel makes a compelling argument against materials like carbon steel which requires frequent recoating,” says presenter Lena Wegrelius, Head of the corrosion department at Avesta Research Center.

Even in initial costs, Outokumpu can offer an advantage. “In some cases, Outokumpu offers material with greater dimensional benefits,” Wegrelius adds. For example, Outokumpu quarto plate is available in several widths, which can help reduce the costs associated with welding and assembly.

85% recycled cont​ent

In her presentation, Wegrelius also stressed the sustainability benefits of Outokumpu stainless. Stainless is recycled material and 85% of the content in Outokumpu stainless is recycled. The figure is the highest in the industry.

“This translates into one ton less CO2 emissions per ton of steel than production derived from only 50% recycled content,” says Wegrelius. “But high recycled content does not impact the quality, durability, or performance of the stainless,” she assures.

“Most plants need repairs. These can range from pipe and tubing to valves and flanges, all of which will become overloaded from a mechanical point of view overtime,” notes Wegrelius. She advises plant operators to “choose the right replacement material for the long-term, not just to last two years.”
