Technofast Tensioning Products for Critical Bolting

ChallengeSafe, reliable and cost-effective operations continue to be a driving force in the nuclear industry, including reducing outage times. Critical bolting applications on pumps, valves and turbines require time consuming and challenging processes, such as torquing and bolt heating, as well as large and heavy tensioning equipment. High temperature hydraulic nuts have been traditionally supplied without any significant technology enhancements and without a secondary release mechanism.

SolutionFramatome’s Nuclear Parts Center is now the exclusive channel to the North American nuclear market for Technofast tensioning products providing 24/7/365 access to an inventory of EziTite Temperature Resistant (TR) Hydraulic Nuts, CamNut Tensioning System and CamBolt System specifically for the nuclear industry. These Technofast tensioning products improve safety, minimize costs and reduce downtime.

Our team stands ready to provide our customers with enhanced technology to provide solutions to meet their critical bolting needs, including a patented secondary release mechanism now incorporated in the EziTite TR Hydraulic Nut. The EziTite TR Hydraulic Nut qualifies as a like-for-like replacement for existing product.

The EziTite TR Hydraulic Nut and the CamNut Tensioning System are user friendly to improve safety and lower REM, requiring little physical effort and are fast to fit and remove. They also reduce the risk of strike and pinch points injuries from other tightening methods.

Customer benefits

• Improve safety, minimize dose and reduce downtime, resulting in lower costs

• Enhanced hydraulic seal design to minimize failures and stuck bolts

• Simpler, easier to handle tooling

• Secondary release mechanism to mitigate risks of stuck studs

• Lower total cost of ownership

Lower costs, reduce downtime and minimize dose with advanced hydraulic fastener systems. Now with an exclusive, patented hydraulic seal and secondary release mechanism.

EziTite TR Hydraulic NutThe EziTite Hydraulic Nut is a precision engineered, high pressure, high performance, hydraulically operated bolt tensioning device that can be quickly and easily fitted and used with Technofast pumping equipment. It has been designed as a direct replacement for existing product, with a patented secondary release mechanism to eliminate the risk of unintended locking. The EziTite TR Hydraulic Nut is user friendly to improve safety, requiring little physical effort and is fast to fit and remove.

Using an EziTite TR Hydraulic Nut reduces costs and downtime while achieving reliable and precision tensioning the first time. The EziTite TR Hydraulic Nut is ideal for applications with elevated operational temperatures where periodic removal and replacement is required. They can be used on bolts of large diameter not suited for wrench tightening, such as pumps and steam valves.

Other features include:

• Drastically reduces service times as tensioning force can be applied to up to 100% of bolts simultaneously

• Operating temperatures from -4°F to 1200°F

• Reliable and tested sealing technology

• 100% tensioning

• High load retention

• Ideal for difficult or confined spaces

• Reactor coolant pump bolting

• Reactor vessel closure systems

• Steam generator manway covers

• Steam turbine closure systems

• Valves

CamNutThe CamNut extends the benefits of hydraulic bolt tensioning to applications, where use of such technology was previously not possible. Thanks to a number of unique features, including the rapid attachment mechanism, the CamNut system is able to tension even the largest bolts fully and accurately in a matter of seconds.

The CamNut’s patented design eliminates the need to replace expensive studs to provide sufficient grip length. Its modular construction reduces overall tool weight, and is designed for extreme situations and adverse conditions. The CamNut also enables high precision tensioning with reduced application time and improved safety.

The CamNut System is ideal for applications where longer bolts for standard bolt tensioners are not available or desirable, and for situations with elevated operational temperatures, such as pumps and steam valves.

CamNuts can be used where:

• Regular maintenance requires repeated adjustment or removal of nuts

• Speed of operation is essential (reduced dose)

• Bolts are large diameter

• Accurate and reliable loading is required on bolting

• Space for tooling is restricted
