Hydraulic Hoses
Hydraulic Hoses
Hydraulic hoses are critical components designed to handle the extreme pressure requirements of hydraulic torquing systems. These hoses facilitate the transfer of high-pressure fluid between the torquing pump and the hydraulic wrench to ensure precise torque application

Twin-Line Configuration
Standard setups utilize a twin-line (bonded) hose design to manage both the supply and return lines simultaneously, preventing tangling and simplifying the workspace.

A hydraulic bolt tensioner is a precision tool used to apply accurate axial load to a bolt using hydraulic pressure. It stretches the bolt directly rather than applying torque, ensuring uniform clamping force, reduced frictional loss, and repeatable tightening—especially critical for large-diameter and high-load bolted joints.
Hydraulic bolt tensioners are widely used in industries such as power generation, oil & gas, wind energy, petrochemicals, heavy engineering, and steel plants. Typical applications include flanges, pressure vessels, heat exchangers, turbines, structural joints, and critical maintenance shutdowns.
Hydraulic bolt tensioning offers higher accuracy, even load distribution, faster installation, and eliminates errors caused by friction in threads and under-head bearing surfaces. It is especially suitable for simultaneous tightening of multiple bolts and for applications where precise preload control is essential.
Selecting the correct hydraulic bolt tensioner depends on bolt diameter, thread pitch, required preload, available clearance, and application conditions. Manufacturers typically provide load charts and technical support to ensure the correct tensioner model is chosen for safe and efficient operation.
Yes, hydraulic bolt tensioners are safe when used correctly and in accordance with manufacturer guidelines. Proper operator training, use of certified high-pressure hoses and pumps, and adherence to recommended pressure limits ensure safe and reliable tensioning during operation.
Yes, hydraulic bolt tensioners can be customised to suit special bolt sizes, restricted clearances, non-standard flanges, or specific industry requirements. Custom solutions are commonly developed for OEMs, shutdown projects, and specialised maintenance applications.
