Flanged Joint Management is now scalable, super-efficient and 100% accurate using the Verif.I.D. Automated Data Management System.
Our core business is the measurement of bolt tension, we do this using either our own equipment or the clients
We both ensure that all bolting is tightened to the correct level before going live and then offering on-going re-monitoring to analyse joint performance in service.
We can measure using any brand of Ultrasonic Monitoring equipment.
Our Technicinas are fully trained in the use of the Boltstress G5, the Dakota Minimax, the Dakota MAX, the Boltscope 1 & 2, the Boltmike 1, 2 ∓ 3. the Norbar USM 1 & 2 and the Raymond Bolt Gauge
Having been involved in the bolting industry since 1991 we have a great deal of...
Although our focus is on measurement our findings normally lead to corrective...
Whenever an application can not be solved using standard torque or tensioning...
We look at the joint geometry, joint conditions, pressures & temperatures; then we determine how to improve performance and propose the optimum solution
Torque and Tension are estimations that go horribly awry in the wrong conditions. We measure what's really happening and implement corrective actions
26 years experience has provided a wealth of knowledge. In the vast majority we can suggest tooling that is safer, quicker and lighter
Many standard bolting procedures are outdated or inaccurate. Using our real measurement results we develop faster, more accurate and safer procedures
The real 'jewel in the crown', everything we do delivers Higher Availability. Shorter shutdowns & less shutdowns. A very high Return on Investment
A simpler, lighter instrument that has the functions to complete most tasks. It is limited to bolts up to 2.5 metre's in length but how often do you come across anything longer ?
We supply services & products to measure bolt tension, bolt stress, elongation or strain. This gives insight into true joint performance
After using Ultrasonics to ensure original joint integrity our products and services may also be used to monitor ongoing joint performance in service...
The G5 broke so many boundaries when it set the new benchmark for ultrasonic bolt tension monitoring, it was difficult too envisage where a new product could surpass it...
Since 1991 Boltstress personnel have been involved in 1000's of applications. This has lead to an in depth knowledge of the many tightening ...
Our consultancy service uses the combined strengths of our technology and practical experience to recommend solutions.
Time is money in any industry.
When your machinery fails to undergo periodic tests and checks, unexpected downtimes are inevitable.
Such is the case with liner bolts that have accumulated a number of failures in the past.
The question is, how does it happen, why does it occur, and what can be done to prevent it from causing problems in the future?
Boltstress Ultrasonics got to the bottom of this situation and conducted a thorough ultrasonic bolting measurement and analysis of the Mills in question. This task led to numerous revelations, which is presented in this post.
Why do bolt failures occur and what can you do to prevent or address it?
Most mill operators are familiar with (and regularly go through) a process known as re-torque.
Re-torque is an expensive exercise resulting in lost production but is believed to be necessary in order to avoid bolt failure that causes unplanned shutdowns.
It doesn't have to be this way however, by eliminating the root cause of the failures we can eliminate the need for re-torque all together.
For the last ten years, our liner bolt specialists have worked with clients in need of diagnostics and solutions for problems with their mill liner bolts. One particular mine experienced an alarming one-a-week liner lifter bolt failure.
Fast forward to today, Boltstress prides itself as being a dependable company with a highly competent maintenance crew that carries out ANY bolt-related works.
