Product Overview
The BTS Series Multi-Bolt Synchronous Hydraulic Tensioning System is designed for applications requiring the simultaneous tensioning of multiple bolts. By applying uniform hydraulic pressure to all tensioners at the same time, the system provides controlled and predictable bolt preload while improving tightening consistency and operating efficiency.
It is particularly suitable for demanding bolting applications in nuclear power plants and other critical industrial equipment.
Product Features
Enables simultaneous tensioning of all bolts, providing uniform and consistent bolt preload across the entire bolted joint.
Eliminates many of the limitations associated with conventional torque tightening methods and provides a more predictable and controllable preload.
Designed to support the stringent radiation protection management and optimization requirements of nuclear power plant maintenance operations.
Manufactured from high-strength steel with excellent corrosion resistance and long service life.
Equipped with a high-reliability piston sealing system. Seals are designed for convenient inspection and replacement during maintenance.
Features a clear piston over-stroke indicator together with an integrated high-pressure relief system.
The over-stroke protection design helps prevent high-pressure hydraulic oil from spraying toward the operator in the event of excessive piston travel, improving operational safety.
Widely used for simultaneous bolt tensioning on nuclear power plant manholes, handholes, inspection openings, and similar bolted closures.
Compared with conventional fully round hydraulic cylinders, the tensioner features a side-cut compact profile, reducing overall tool weight and allowing closer positioning between adjacent tensioners.
Oval-shaped hydraulic cylinder configurations are available for customized applications where bolt spacing or installation space is particularly restricted.
The nut rotation ring incorporates magnetic elements, simplifying positioning and installation during operation.
Each hydraulic cylinder is equipped with an individual hydraulic connection, providing flexible system arrangement and easier connection of multiple tensioners.
The tensioner dimensions and body profile can be custom-designed according to different bolt spacing requirements, helping minimize overall tool weight while maximizing accessibility.
Uses high-performance polyurethane seals for reliable sealing under repeated high-pressure operating cycles.
