HYDROTORC CONTROLLED BOLTING SERVICES
Controlled bolting with HYDROTORC is the safe choice for joint assembly during plant construction, turnarounds and ongoing maintenance. We’ll work with you to identify and manage scopes of work to suit your requirements and all flange details will be recorded for your reference.
No matter the size of the project, we’ll provide an expert team – so you can relax knowing that all work is carried out by experienced technicians trained to the leading industry standards.
BOLT TORQUEING
Even smaller bolts need to be tightened correctly, the use of a calibrated hand torque wrench by a trained and competent user can help to ensure the integrity of the joint, reduce failures and extend the lifetime of components.
Benefits of Bolt Torqueing
- Control of torque applied to the bolt.
- Control of torque applied to the bolt.
- Eliminate overtightening and yielding of bolts.
- Eliminate damage to flanges or gaskets due to overtightening.
- Ensure the overall integrity of the joint.
BOLT TENSIONING
Bolt Tensioning works differently to torque. Instead of applying torque to rotate a nut which then creates bolt load, a tensioner grabs and pulls the threads protruding beyond a nut, stretching the bolt axially, lifting the nut from the surface. This allows the nut to be rotated back to the flange with a minimal amount of torque.
Benefits of Bolt Tensioning
- Stability and ease of control
- Highly accurate
- Minimal torque required
- Minimal load sharing/cross talk between neighboring studs
- Faster – bolts can usually be tightened simultaneously
NUT SPLITTING
Hydraulic nut splitters make it easy for our team to remove even the most stubborn seized nuts. This is safer than alternative methods and saves time and money.
Benefits of Nut Splitting
- Uses hydraulic force to eliminate labor intensive methods
- Tools available to split most sizes of nut
- Models available for BSA/ANSI flanges for oil and gas applications
FLANGE SPREADING AND ALIGNMENT
Flange alignment is vital when constructing new pipework, commissioning or during routine maintenance. HYDROTORC personnel have the tools to bring misaligned flanges in line - enabling controlled and efficient bolting.
Benefits of Flange Spreading And Alignment
- Hydraulic and mechanical flange alignment tools easily align flanges before controlled bolting.
FLANGE MANAGEMENT SOFTWARE
Bespoke Integrity Data Management System (iDMS) for any asset / plant / site to record data, plan, manage, and provide a project delivery tool for the on site execution of any Joint Integrity workscope.
Benefits of Flange Management Software
Provides a permanent, searchable record of every joint’s history, along with a means to manage, track and control the status of every bolted joint during the planning / execution of a bolting workscope, helping to avoid errors, improve efficiency, and ensure a client’s procedures are being correctly applied.Contracting Model

HOT BOLTING
Rely on HydroTorc extensive safety record when looking to remove or replace bolts on pressurised flanged joints using Hot Bolting. HytroTorc exclusively offers the safe Hot bolting clamps which have secured containment of Oil and Gas systems around the world for more than a decade.
HydroTorc has decades of experience using traditional manual, hot bolting on flanges with 8 bolts or more however a specialist solution is required for 4 bolt flanges or any flange with significantly damaged or degraded bolts.
Benefits of Hot Bolting
- Increase safety & integrity
- DNV Certified
- Each clamp is tested to 1.5x the design pressure of application
- Replace damaged or corroded bolts
- Upgrade or align material specification
- Limit the number of ‘containment breaks’
- Replace ‘old for new’ bolts before shutdown
- Reduce costs
- Eliminates or reduces shutdown time
- Prevent unplanned shutdown
MANPOWER TRAINING & CERTIFICATION
Supply training and compliance management to any client, contractor, or sub-contractor involved in controlled bolting, onsite machining, or flange management activity.
Benefits of Manpower Training & Certification
Bolting is a specialized skill where training is not a guarantee of competency. Controlling the competence of personnel involved in the assembly and controlled tightening of joints has consistently been proven to be a key factor in preventing leaks.
