Bolting & Tensioning
Good flange management makes the difference between a care-free production and an unsafe leaking facility.
While nearly all attention goes to ‘mission-critical’ equipment such as reactors and rotating equipment, failure of one of the thousands of bolted connections that keep a facility together can result in unsafe situations, leaks and potentially halt production of a plant. These bolts can be related to pipe flanges, equipment fixations and foundations.
We apply the full spectrum of bolting & torquing tools and techniques (e.g. ultrasonic bolt load measurements) to give you a leak-free & reliable facility.
Our seasoned technicians are ready to take on any challenge, understanding that safety remains the #1 priority when executing work in a live facility.
Full array of tools
We have a full array of tools to execute torquing and tensioning projects (including subsea), for tightening and loosening bolts as necessary.
Should studs break-off, our experts have the knowledge and experience to extract those studs without jeopardizing the timeline.
Determine actual bolt forces
For critical connections, it is often necessary that the actual applied bolt force can be guaranteed. If this type of bolted connection should fail, consequences are severe and repair costs extreme high.
We have incorporated ultrasonic measurement within our bolting services for those critical connections and can therefore exactly measure and periodically re-measure bolt forces. The major advantage is that no extra modifications are required to your asset.
Live bolt replacement
Corroding flange bolts can pose a serious safety, production and environmental risk. Traditionally, the whole line would have to be taken out of commission, purged and depressurized before the corroded bolts can safely be replaced.
With our Hot Bolt Clamp solution, our experts can safely replace corroded bolts whenever required, without precariously having to wait for a shutdown. By taking it out of the turnaround scope, TARs can be shortened, allowing increased production.
Smart flange protection techniques
- Applying special coatings like Belzona 3412 that help avoid water egress.
- Applying a rope in between flanges while blasting, thereby protecting the packing.
On-line flange management
Our experts have developed an on-line flange management software tool that allows all works undertaken on bolted connections to be tracked. All activities are logged, including inspection results and when a flange was tightened, with which force, with which tool, with which grease and by whom.
This enhances efficiency (incl. real-time reporting), enables compliance (audit trail!) and allows predictive flange management: if there’s an issue with a certain bolt, we know where similar bolts are located.
