Patriot International offers specialised hot bolting services for maintaining bolted joints on live systems. Our expert team uses advanced hot bolting techniques to safely replace or tighten bolts, ensuring joint integrity and system reliability without the need for shutdowns.
Hot bolting is a controlled maintenance method that allows for the sequential removal, replacement, or tightening of bolts on pressurised systems without disrupting operations. This technique is essential in high-demand industries like oil and gas, petrochemical, and power generation, where maintaining joint integrity and preventing leaks is critical to operational continuity.
Hot bolting allows bolt replacement and maintenance to occur while the system remains fully operational, preventing costly shutdowns and interruptions to production.
By using specialised tools and equipment, Patriot International minimises potential hazards, ensuring each bolt is safely managed without disturbing the system's pressure and load distribution.
With regular hot bolting maintenance, joints experience less stress and wear, reducing the risk of leaks or failures and extending the lifespan of critical components.
Patriot International’s hot bolting process is structured around stringent safety protocols. It begins with a thorough risk assessment, where we review maintenance records and inspect flanges and bolts. Technicians then use calibrated tools to carefully remove, clean, lubricate, and replace bolts while maintaining the flange’s compression. Specialised clamps prevent load transfer to the gasket, reducing the risk of damage and ensuring joint integrity.
Hot bolting in pressurised pipelines prevents system downtime, ensuring continuous production in oil and gas facilities.
Safely reinforces the integrity of valve and flange joints, maintaining secure connections across essential infrastructure.
Critical for industries where live maintenance is necessary, such as refineries and offshore platforms, to ensure compliance with safety standards and reduce leak risks.
Patriot International combines expert technicians, advanced equipment, and rigorous adherence to safety standards in every hot bolting project. Our hot bolting services follow the highest technical mechanical joint integrity (TMJI) requirements, ensuring your bolted connections are maintained safely and effectively, keeping your operations seamless. With Patriot International as your partner, you benefit from reliable, on-site maintenance solutions designed to support safe and efficient operations across demanding environments.
Patriot ensures compliance with ASME PCC-1, "Guidelines for Pressure Boundary Bolted Flange Joint Assembly," developed by the American Society of Mechanical Engineers (ASME), particularly in the context of hot bolting operations.
