Boltstress Ultrasonics - Bolt Tension Measuring Services

Boltstress Ultrasonics provides specialist bolt tension measurement services. This technology provides real bolt stress measurement results. We supply services and products to measure bolt tension, bolt stress, elongation or strain. This gives insight into true joint performance and aids solution determination by using real (not assumed) data.

Bolt tension measurement systems and services

Boltstress Ultrasonics’ core business is the measurement of bolt tension, which is conducted using either our own equipment or the clients to eliminate critical bolted joint failure, leaks, costly downtime, potential safety hazards and guess work.

Although our focus is on measurement, our findings normally lead to corrective actions. To facilitate this we offer to supply the required tightening equipment to make necessary adjustments. Wherever an application cannot be solved using standard torque or tensioning product, we design and source special equipment.

Ultrasonic bolt tension measurement technology

Ultrasound can be used to determine bolt tension supplies data and therefore achieve a leak free start-up and prevent in-service failures of dynamic joints. Boltstress Ultrasonics has been involved in the development and use of the ultrasonic bolt tension measurement technology since 1991. We offer ultrasonic bolt tension monitoring systems and consultative on and off-site services.

Ultrasonic bolt tension measurement technology was first developed for the Apollo space missions. It provides the ability to see the real tension that a bolt retains after tightening and has been used to solve a multitude of bolted joint problems, ranging from Formula One racing cars to turbine couplings.

Tightening systems

Through the experience of many tightening system applications, Boltstress Ultrasonics’ has in-depth knowledge of many tightening methods and specialised tool designs to solve problems. As a result, we offer methods and technologies unfamiliar to many engineers.

Boltstress Ultrasonics’ technicians are fully trained in the use of the Boltstress G5, the Dakota Minimax, the Dakota MAX, the Boltscope 1 and 2, the Boltmike 1, 2 and 3, the Norbar USM 1 and 2, and the Raymond Bolt Gauge.

Joint performance monitoring systems

Boltstress Ultrasonics’ products and services can monitor on-going performance of joints in service, without disturbing the joint. We use ultrasonic technology to ensure original joint integrity.

To ensure plant reliability we also offer re-monitoring service, which includes tabulating and graphing results for analysis, allowing clients and OEMs to make informed decisions to improve equipment uptime.

Consultancy services for mills, heat exchangers and pressure vessels

Our consultancy service uses the combined strengths of our technology and practical experience to recommend solutions. Applications for Bolstress Ultrasonics technology and expertise includes mills, heat exchanger and pressure vessels, slew ring bearings, valves, and turbines.
