A hydraulic torque wrench is a precision bolting tool used to apply controlled torque to nuts and bolts using hydraulic pressure. It operates by converting hydraulic pressure into rotational force, ensuring accurate, repeatable tightening for critical industrial applications.
Hydraulic torque wrenches are widely used in oil & gas, power plants, refineries, steel plants, cement plants, wind energy, heavy manufacturing, and EPC projects where high-torque, controlled bolting is required for safety and reliability.
Square Drive Hydraulic Torque Wrenches are versatile and ideal for general bolting applications.
Low Profile (Cassette Type) Hydraulic Torque Wrenches are designed for tight or restricted spaces where standard tools cannot fit.
Both deliver precise torque but serve different site constraints.
Selection depends on bolt size, torque requirement, and space constraints:
Square Drive Wrenches: preferred for open access bolting
Low Profile (Cassette) Wrenches: ideal for restricted clearances common in pipe racks, flanges, and heat exchangers
Selecting the right hydraulic torque wrench depends on required torque range, bolt size, available working space, and application type. Our team can assist in choosing the correct model to ensure safe, efficient, and accurate bolting operations.
Yes. Hydraulic torque wrenches are among the safest and most accurate bolting tools available. When used with calibrated pumps and proper procedures, they provide ±3% torque accuracy, reducing bolt failure, rework, and safety risks.
Yes. Our hydraulic torque wrenches are designed for rugged Indian industrial environments, including refineries, power plants, cement plants, and steel plants. They perform reliably under high temperature, dust, humidity, and continuous site use conditions common across Indian EPC projects.
A complete system includes a hydraulic torque wrench, calibrated hydraulic pump, pressure hose, couplings, and reaction arm or cassette. All components must be compatible to ensure safe and efficient operation.
