Customer success stories

People Providing an antidote to disaster Philippe Nouaille is responsible for overseeing how nuclear plants could be better secured against earthquakes – the natural disaster which gives nuclear engineers their biggest headaches. Více informací

Customer Cases A Wind-Win Situation Wind turbine towers are designed to flex and bend, which helps them dissipate the significant forces being exerted upon them. However, this had been causing dangerous failures in the bolts. Více informací

Customer Cases Eliminating bolt loosening for good At power plants across the world, gas turbines are becoming increasingly vital to the world’s power supplies. Mitsubishi Heavy Industries currently manufacture ultra-large gas turbines, which are more than six metres tall and over 16 metres long. Více informací

Customer Cases The power of the sun: transformed by Siemens turbines Assembling an industrial-sized turbine requires acres of room. It also requires thousands of bolts and washers to be assembled and tightened to guarantee a service life of the product, which in the solar energy, biomass, oil and gas sectors, is typically upwards of 30 years.

Once tightened the bolt will hold

“Nord-Lock is one of our solutions to avoid loose bolts and we turned to it after doing a technical and business report. We’d had an incident when a bolt had been poorly tightened and it took engineers 10 weeks to verify all the other bolts. You can imagine the waste of time and money! With Nord-Lock we can be certain that once tightened the bolt will hold. Don’t forget we are working in a nuclear power plant not a supermarket and cannot afford to make the slightest mistake!”
