Bolting
A single leaking flange can compromise the safety of an entire plant. At Radiant, we provide comprehensive Joint Integrity Management through advanced manual and hydraulic bolting solutions. Our goal is simple: achieve leak-free startups and ensure the long-term reliability of your pressurized systems.
By combining calibrated technology with expert technicians, we accelerate maintenance schedules while maintaining the highest precision in bolt load application.
Our Bolting Arsenal
We utilize a full suite of specialized tools to handle everything from routine pipework to the most critical reactor closures.
· Hydraulic Bolt Tensioners: Ideal for large-diameter studs and critical joints. These tools provide direct axial stretching, ensuring uniform gasket compression and eliminating the inaccuracies caused by thread friction.
· Hydraulic Torque Wrenches: Low-profile and square-drive wrenches designed to deliver high-output torque in confined spaces, ensuring every nut is tightened to exact engineering specifications.
· Manual Torque Solutions: High-quality, calibrated manual wrenches for smaller-scale joints where precision is still a non-negotiable requirement.
· Flange Spreaders & Nut Splitters: For the safe and efficient “break-out” of stubborn, corroded, or seized joints. Our hydraulic splitters provide a cold-cut, spark-free solution that eliminates the need for dangerous hot work.
The Radiant Advantage: Joint Integrity
Our service goes beyond just “tightening bolts.” We follow a systematic Joint Integrity process to protect your assets:
Feature | Performance Benefit |
Controlled Tightening | Eliminates the risk of over-stretching bolts or crushing gaskets. |
Simultaneous Tensioning | Linking multiple tensioners ensures perfectly even load distribution across the flange. |
Friction-Free Accuracy | Tensioning bypasses the “K-factor” (friction), providing up to 90% more accuracy than traditional methods. |
Spark-Free Removal | Our hydraulic spreaders and splitters ensure safety in volatile, hydrocarbon-rich environments. |
Applications Across the Sector
