New Brunswick Power Belledune Generating Station has been using Superbolt products since the mid 2000’s in their steam turbine for valves bolting.
In this video we show how EzFit expansion sleeve coupling bolt was able to solve a problem when standard fitted coupling bolts were causing severe damage on the turbine couplings.

Boltight manufactures both standard and custom built tooling for subsea applications. The subsea tensioners incorporate components that helps to save installation time, cost efficient, protects the environment and conforms to the requirements of the European Pressure Equipment Directive.
All subsea tensioners are assembled, filled with oil and have been pressure tested before dispatch. Boltight subsea tensioning tool is supported by a range of ancillary equipment such as high volume pumps, diver control valves, long length down line and hose reels.
Boltight’s Typhoon range of bolt tensioners offer a high-load, low profile solution for space-restricted applications that demand high and accurate preloads. A solution widely used within the Wind industry where such space-restricted connections are common. Additional convenience features such as a spring loaded gear drive for nut rotation and automatic piston retraction, ensure that Typhoon bolt tensioners are the ideal choice for any application demanding a powerful, portable and user-friendly bolt tensioning tool.
Boltight’s Piston Retraction system takes the hard work out of resetting bolt tensioner piston stroke. Depending on the design of the tensioner, the pump will give automatic piston retraction or assisted piston retraction.
Quick and easy, it saves operation time, reduces operator fatigue, and promotes safe and efficient working practice.
Safety is everything for the Irish Rail. When they noticed that the bolts on their axle boxes were loosening due to vibration, they decided to replace the locking-wire mechanism on the wheel sets with Nord-Lock washers.
“Since the introduction of the Nord-Lock washers we have not had one instance of a bolt coming loose which give us a lot of comfort from a safety point of view”, says Conor Doyle, Senior Fleet Technical Support at Irish Rail.
Two years on since the first installation of Nord-Lock washers and Irish Rail has been more than satisfied with the outcome.

Don’t miss the new Nord-Lock Group video that focuses on the hands-on aspects of our Expansion bolt technology.
The video takes you through an entire Superbolt Expansion bolt installation process, from preparation and positioning to the fitting of the bolts into the holes when aligned.
The video was filmed on location at the EDF hydro electric power station, Usine Électrique de Malgovert, in the beautiful French Alps, where electricity generator giant EDF joined forces with the Nord-Lock Group to install Superbolt on the Malgovert turbines.
“EDF chose Superbolt Expansion bolts to simplify future maintenance. Ease of installation and removal due to the expanding sleeve technology insures against future damage to coupling bolt and coupling holes. There is no longer a need to re-machine holes or replace bolts,” says Steve Brown, expansion bolt specialist with the Nord-Lock Group. “This film is for everyone who wants the optimal bolted coupling, using and making the most of a Superbolt installation.”
Designed with the benefit of more than 30 years experience in the field, Boltight has created a range of tools to meet the challenge of today’s bolt tensioning requirements.
Just watch how easy it is to install these tensioners!
