Hydraulic torque wrenches are indispensable tools in industries requiring high-torque fastening, such as oil and gas, wind energy, and heavy machinery. At Petra Carbon, we design robust, precision-engineered hydraulic torque wrenches that deliver unmatched accuracy, safety, and efficiency for critical bolting applications. This guide explores how hydraulic torque wrenches work, their advantages, and why Petra Carbon is the trusted partner for industrial bolting solutions.
What Is a Hydraulic Torque Wrench?
A hydraulic torque wrench is a powered tool that uses hydraulic pressure to apply precise torque to bolts, nuts, and flanges. Unlike manual or electric wrenches, hydraulic systems generate immense force (up to 100,000 Nm) with minimal operator effort, making them ideal for large-scale or high-stakes applications.
Key Features of Petra Carbon’s Hydraulic Torque Wrenches:
Torque Range: 500 Nm to 50,000+ Nm for M20 to M200 bolts.
Safety: Reduced reaction force to prevent operator injury.
Durability: Hardened steel construction for 10,000+ cycles.
