Emergency repair of a 50-year-old dry nitrogen compressor foundation in a steel plant
Cogne Acciai Speciali, a leading producer of stainless steel products based in Aosta, Italy, turned to Burckhardt Compression Italy after sudden and excessive vibrations led to the unexpected shutdown of the 50-year-old dry nitrogen compressor. A root cause analysis detected cracks in the foundation and damaged anchor bolts. Thanks to the immediate local support and close collaboration with the customer, the foundation was repaired on-site and the system was smoothly restarted within the customer's tight schedule.
