Swedish fastener manufacturer BUMAX received a SEK 1.7 million (US$177,333) order for corrosion resistant and maintenance free studs to be used for a wind farm off the Belgian coast.

BUMAX said it won the order to supply stainless studs, nuts and washers for the 219MW Northwester 2 offshore wind power plants because it makes high strength fasteners with excellent corrosion resistance suitable for extremely challenging North Sea conditions.

“This prestigious order is a testament to BUMAX’ ability to develop and market premium stainless steel fasteners of the highest quality, for the most complex constructions and aggressive conditions,” said Patrik Lundström Törnquist, Managing Director of BUMAX.

Delivery was completed in July. The wind farm is expected to be operational in the first half of 2020.

The product chosen for this project is BUMAX SDX 109, a high strength super duplex fastener with excellent mechanical properties, and exceptional resistance to general crevice, pitting and stress corrosion in aggressive environments.

“SDX 109 meets the customer’s requirements for a corrosion resistant stud to fasten the wind turbine generator external platform to each of the 23 wind turbine foundations,” according to BUMAX.

The studs will have to be maintenance free throughout the 27-year design life of the turbines – which conventional carbon steel bolts are simply not capable of. Web: BUMAX-fasteners.com
