Hydraulic Torque Wrench Calibration

Operator Friendly Systems for Production Maintenance

A.K.O.’s Hydraulic Torque Wrench Calibration Systems are the most rugged and accurate systems in the industry, and are built to provide accuracy, efficiency, and reliability in your torque wrench calibration procedures. These systems use a Pressure Transducer to measure the Input Pressure and Torque Transducers to measure the Output Torque. Many Hydraulic wrench manufacturers use AKO systems for production and maintenance. With a combination of AKO torque transducers, these systems can be configured with a range from 50 lbf∙ft to 150,000 lbf∙ft, the highest capacity in the industry. The Input Pressure Transducer has a range of 1000 psi to 10000 psi. Many systems that were purchased 30+ years ago are still in use today. AKO’s Hydraulic Torque Wrench Calibration Systems are modular and can be expanded to add the ability to calibrate Torque Multipliers and Pneumatic Wrenches in addition to the calibration of Hydraulic Torque Wrenches.

The Importance of Hydraulic Torque Wrench Calibration in Critical Applications

Precision torque application is essential in industries where safety, efficiency, and compliance are non-negotiable. Hydraulic torque wrench calibration ensures that every fastener is tightened to the specifications required for structural integrity and operational performance. Whether in high-risk environments or routine maintenance, calibration plays a key role in preventing failures, extending equipment life, and meeting strict industry standards.

Key Conditions Where Calibration is Crucial

• Industrial Maintenance: facilities that rely on heavy machinery, such as manufacturing plants and power generation sites, require precise torque application to avoid equipment failure and costly downtime. Regular calibration ensures wrenches perform consistently within specified tolerances.
• Demanding Environments: In sectors like oil and gas, offshore drilling rigs and platforms operate under extreme conditions where improperly torqued bolts can lead to catastrophic failures. Hydraulic torque wrench calibration ensures the safety and reliability of critical bolted connections.
• Safety-Critical Tasks: Industries such as aerospace, nuclear energy, and transportation demand the highest level of precision. A miscalibrated wrench can compromise the integrity of aircraft structures, pipelines, and infrastructure, leading to safety risks and regulatory non-compliance.

Maintaining Accuracy in Your Hydraulic Torque Wrench Calibration Procedures

A.K.O. offers a comprehensive range of hydraulic torque wrench calibration systems designed to streamline the calibration procedure process while delivering unmatched precision. To maintain precision, organizations must implement strict calibration procedures that align with manufacturer recommendations and regulatory guidelines.

Tool Care – Regular calibration intervals are crucial for ensuring torque wrench remain within specified tolerances. The frequency of calibration should be based on factors such as usage intensity, environmental conditions, and industry standards. Conducting calibration in a controlled environment, where temperature, humidity, and external vibrations are minimized, further enhances accuracy and prevents measurement deviations.

Compliance – Using certified calibration equipment is another key factor in maintaining accuracy. Calibration systems should be traceable to industry standards such as ISO 17025, ensuring consistency and reliability. Proper handling and storage of both torque wrenches and calibration equipment also play a significant role in long-term accuracy. Keeping tools clean, dry, and free from contaminants helps prevent mechanical wear, corrosion, and degradation that could impact performance.

Education – Operator training is also essential. Technicians must be well-versed in best practices, including applying consistent load techniques and correctly interpreting calibration results. Routine inspections of hydraulic systems, hoses, and connections should also be performed to identify and address any potential issues before the affect accuracy.

By implementing these practices, business can ensure their hydraulic torque wrenches provide precise, repeatable performance, reducing the risk of failures and maintaining compliance with industry standards.
