This hydraulic wrench is designed for tightening and loosening large-diameter flange bolts, with torque output ranging from 82 ft.lbs (112 Nm) to 51,874 ft.lbs (70,320 Nm). The system includes a hydraulic pump, oil hoses, and interchangeable sockets to match bolt sizes from M16 to M120. Two variants are available: standard hydraulic wrenches and low-profile models for confined spaces. The tool operates via hydraulic pressure, delivering precise torque without manual effort.
The wrenches are constructed with hardened alloy steel drive components and sealed hydraulic cylinders to withstand high-pressure cycles. Low-profile models are engineered for use in tight flange arrangements where standard wrenches cannot fit, accommodating hex nuts from S19 to S175. The system includes safety valves to prevent over-pressurization and pressure gauges calibrated in both ft.lbs and Nm. All models are built to ISO 15024 standards for hydraulic torque tools.
These tools are primarily used in oil and gas, petrochemical, power generation, and shipbuilding industries where large flange connections require controlled torque application. Buyers include maintenance teams at refineries, offshore platforms, and industrial plants. Orders are typically placed for single units or small sets, with delivery lead times of 4 to 8 weeks. Payment terms are commonly T/T in advance or LC at sight, with FOB Shanghai or CIF port options.

Verify the torque calibration of each wrench before shipment. Request a calibration certificate from a certified lab, showing test points and deviation values. Confirm that the hydraulic system includes a pressure gauge with ±2% accuracy and that all hoses are rated for 700 bar. Do not accept tools without documented calibration, especially for safety-critical flange connections.
Confirm Incoterms - typically FOB Shanghai or CIF port. Lead time is 4 to 8 weeks due to custom assembly and testing. Payment is usually 50% advance with balance against shipping documents. Ensure the supplier provides a full set of documentation: user manual, hydraulic system diagram, warranty terms, and spare parts list. Confirm that replacement seals and sockets are available locally or can be shipped quickly.
Inspect the wrench upon delivery for hydraulic leaks, damaged hoses, or missing components. Test the tool under low pressure before full operation. Check that the pressure gauge reads accurately and that the socket engages the nut fully without slippage. Retain a sample torque reading for future comparison. For critical applications, conduct third-party torque verification using a certified load cell.
