EziTite® TR High Temperature Hydraulic Nut

Model No.: EziTite TR

The EziTite® TR High Temp Nut is a patented, specialised tensioning device designed for simultaneous multiple bolt tensioning in high-pressure and extreme-temperature environments. It is engineered to operate reliably in conditions reaching 550°C and higher, making it suitable for applications such as refineries, steelworks, autoclaves, boilers, steam turbine half-joints, gas turbine casings, and flange makeup. The design utilizes high-pressure hydraulics to apply precise, even bolt loads with minimal physical effort, and it incorporates a unique sacrificial ring as a secondary backup release mechanism to ensure safe removal if service damage or misalignment occurs. Features: Patented Metal-to-Metal Seals : Engineered to deliver superior technical efficiency and reliable sealing performance in extreme environments. High-Temperature Resistance : Specifically built to withstand operating temperatures up to 550°C and higher. Secondary Backup Release Mechanism : Features a unique sacrificial ring that can be split and removed to allow normal retraction and safe removal in the event of service damage or misalignment. Load Loss Elimination : Designed with a smart internal configuration engineered to completely eliminate load losses during the tensioning process. Compact Footprint : Built with a compact design profile suitable for installation in confined spaces. Simultaneous Multi-Tensioning : Configured to tension multiple fasteners at the same time to ensure uniform bolt loads. Benefits: Reduced Operational Downtime : The simultaneous tensioning capability streamlines asset assembly and significantly reduces disassembly downtime. Precise Fastener Seating : Eliminating load losses ensures a precise, highly reliable fit without requiring extensive physical effort from installation crews. Enhanced Service Safety : The sacrificial ring mechanism provides a dependable extraction path, preventing tools from becoming permanently stuck or compromised due to severe thermal service damage. Cost and Technical Efficiency : The patented metal-to-metal sealing and load retention systems offer distinct technical and cost/benefit advantages over alternative tensioning devices. Application Versatility : Provides a dedicated bolting solution across critical processing and heavy industrial sectors where high thermal and pressure stress are constant variables. Ideal applications: Pressure vessel closures : Providing uniform sealing and easy extraction on heavy industrial autoclaves and boilers. Flange makeup : Ensuring precise, even bolt loads across high-pressure pipeline and equipment flanges to prevent leaks. Turbine joints : Securing critical split-line casings on both gas turbines and steam turbines where thermal movement is extreme. High-temperature applications : Operating reliably in environments reaching 550°C and higher where standard elastomeric seals would fail.
