Radiant has successfully executed over 30 Breechlock heat exchanger maintenance projects, consistently delivering safety and precision for these mission-critical refinery assets. Our comprehensive service scope includes the expert handling of Thread Lock Rings (TLR), channel covers, compression rings, and partition boxes, alongside seamless bundle removal and hydrojetting. We specialize in complex in-situ machining and rigorous hydrotesting, often exceeding 220 kg/cm²g to meet the highest industry standards. Through meticulous technical execution, Radiant ensures optimal equipment integrity, helping refineries maintain operational continuity and peak performance in high-pressure environments.
Radiant has expertly executed over 10 flare tip replacement projects for leading energy sector companies, managing everything from initial mounting to comprehensive repairs. Our teams specialize in the complex logistics of de-mounting and replacing heavy-duty tips weighing up to 3 tons at challenging heights of 120 meters. Utilizing advanced lifting technology—including heavy-lift cranes, mast climbers, and specialized lifts—we ensure seamless execution of integrated piping and refractory work tailored to specific client requirements. This proven capability in high-elevation, high-risk environments underscores our commitment to precision, safety, and operational excellence in critical infrastructure maintenance.
Radiant provides comprehensive, critical catalyst handling services for petroleum refineries and fertilizer units, prioritizing safety and technical precision. We specialize in the nitrogen-cooled evacuation of spent catalysts and offer expert loading solutions. Through our technical collaboration with PETROVAL, France, we deploy advanced DENSICAT, CATAPAC, and UNIDENSE technologies for reactor vessels and reformer tubes.
Our operations are backed by a global-standard Life Support Breathing System, enabling safe performance in inert and hazardous atmospheres. Beyond handling, we execute internal repairs, specialized welding, and flame-proof video inspections, ensuring total asset integrity in the most demanding environments.
Radiant offers advanced mechanical decoking and pigging services for fired heaters. Utilizing a totally safe, self-contained bi-directional system, we effectively remove coke scaling without chemical agents or tube damage. Our trailer-mounted double-pumper units enable simultaneous cleaning of multiple passes, significantly reducing downtime.
This eco-friendly method increases heater efficiency and reliability while minimizing maintenance costs. Our system expertly navigates radius bends and various header types, allowing for precise tracking and rapid problem-area identification—ensuring your assets achieve peak productivity with uncompromised safety.
Radiant provides comprehensive planned and emergency pipeline services, including Hot Tapping, Line Stops, and Cold Cutting. Our expert team manages hot tapping from ½” to 96” at pressures up to 1500# and temperatures reaching 400°C. We utilize the innovative CAM-LOR interlock plug system for line stops up to 56”, offering superior leak protection and efficient installation for valve replacements and rerouting.
Supported by an in-house manufacturing facility, we fabricate and rent high-pressure fittings and specialized equipment tailored to client needs. Our engineering-driven approach ensures maximum safety and minimized downtime across various metallic pipeline materials.
Radiant’s professional In-Situ Machining and Cold Cutting services eliminate the logistical burden of equipment removal, bringing high-precision repairs directly to the field. Our spark-free cold cutting technology is essential for high-risk zones like HCUs and NCUs, enabling simultaneous cutting and beveling without creating Heat Affected Zones (HAZ).
Additionally, our on-site flange refacing restores seating surfaces—from small-bore pipes to large heat exchangers—ensuring gas-tight seals that prevent fugitive emissions. By correcting corrosion and erosion damage in situ, we significantly reduce downtime while maintaining the metallurgical integrity and safety of your critical facility infrastructure.
Radiant provides comprehensive Joint Integrity Management to ensure leak-free startups and long-term pressurized system reliability. Combining calibrated technology with expert technicians, we offer a full suite of bolting solutions:
Hydraulic Tensioning & Torquing: Direct axial stretching and high-output torque for uniform gasket compression, eliminating friction-related inaccuracies.
Manual Solutions: Precision tightening for smaller-scale, critical joints.
Safe Break-out: Spark-free hydraulic nut splitters and flange spreaders for volatile environments.
Our systematic approach ensures perfectly even load distribution across reactors, heat exchangers, and high-pressure piping, accelerating maintenance schedules while upholding uncompromising safety and metallurgical integrity.
Radiant provides industrial re-tubing services for heat exchanger bundles and air-fin coolers, designed to restore thermal efficiency and extend asset life. Utilizing state-of-the-art automated equipment, our expert teams execute large-scale re-tubing during critical shutdowns with unmatched speed and precision.
Our comprehensive process includes precision tube pulling, tube-sheet hole cleaning, and automated tube expansion and seal welding to ensure leak-free performance. Whether performed on-site or in our specialized facility, we handle complex metallurgical requirements and internal component replacements, such as baffles and tie rods, delivering high-quality, reliable solutions that meet stringent global pressure vessel standards.
