NORBAR PRODUCT PORTFOLIO

nnnn

Norbar is the only torque equipment manufacturer able to offer tool and

nnnn

instrument recalibration services to the original factory standard on four

nnnn

continents. The accredited laboratories in Australia, USA and Singapore

nnnn

use the same equipment and procedures as the factory's UKAS accredited

nnnn

laboratory in the UK. A further Norbar laboratory is in operation in

nnnn

Shanghai.

USM - ULTRASONIC BOLT LOAD

nnnn

MEASUREMENT

nnnn

Norbars USM-3 is one of the most powerful tools ever to be made available to engineers

nnnn

concerned with bolted joint integrity The USM-3 uses ultrasound to measure the change in length

nnnn

of bolts during and/or after the tightening process. Unlike indirect methods of tension control

nnnn

such as torque or torque and angle, ultrasonic measurement of bolt load or elongation bypasses

nnnn

the problems of friction and other variables resulting in significantly more accurate bolt tension.

nnnn

Issues such as vibration loosening bolt yielding embedment relaxation, and many others can be

nnnn

identified and addressed prior to failure; likewise, verification of residual stud tension after using

nnnn

hydraulic or mechanical tensioning systems or post-heating provides data that can be uploaded to

nnnn

a computer saved as an Excel spreadsheet and printed for hardcopy documentation. The USM-3

nnnn

has been laboratory and field proven to be the most accurate, reliable and cost effective solution

nnnn

to bolting failures which could lead to leaks, capital equipment damage and risks to workers.

nnnn

Regardless of whether the project is under construction, in fabrication or undergoing maintenance,

nnnn

the USM-3 excels at verification and longterm monitoring of bolt tension and elongation. Norbar's

nnnn

USM instruments have been chosen by many of the largest bolting service companies as their

nnnn

preferred instrument for power generation maintenance work Critical applications for fossil, nuclear

nnnn

and wind power have all been made surer and safer through implementation of bolt load and

nnnn

elongation verification. Common applications include: Steam turbine compressor rotors, inner and

nnnn

outer casings, coupling bolts, HP & LP blade rings, main steam inlet flanges, throttle valves, generator

nnnn

bearing brackets and generator through bolts. Nuclear Reactor coolant pumps, baffles, reactor

nnnn

pressure vessels, man-way covers, foundation bolts. Wind power foundation bolts, yaw bearing bolts,

nnnn

hub to blade, hub coupling generator coupling and tower bolts.

PRODUCT SERVICE

nnnn

The diverse needs of the power generation industry from nuclear to wind, mean that Norbar's

nnnn

standard range of products are not always suitable. This is particularly true with regard to difficult

nnnn

to reach bolts, for example, on wind turbines or where an even higher degree of accuracy and

nnnn

verification is required as in the nuclear industry Norbar therefore offers an Engineer to Order

nnnn

service that spans a range from modified reaction arms through to completely one off tools or

nnnn

measurement systems.
