Our lab is equipped to handle the high-force requirements and specialized components of hydraulic torque systems used in critical bolting applications across heavy industry, petrochemical, power generation, and structural fields.
With the increasing demand for precision bolting in safety-critical environments, E&S ensures your hydraulic torque tools deliver reliable, repeatable performance where it matters most. From mobile field units to full bolting systems, we offer fast turnaround and support to keep your tools calibrated and your crews confident.
At a Glance
Hydraulic Torque Tools We Calibrate
We calibrate and service the following hydraulic torque wrench types
Square Drive Hydraulic Wrenches
Commonly used for general-purpose bolting — we verify output torque across the tool's rated capacity with certified transducers and matched hydraulic pressure.
Low Profile (Cassette) Wrenches
Designed for tight clearances and flange work — calibrated for precise torque delivery and consistent output under varying load conditions.
Custom & Specialty Hydraulic Tools
Adapted heads, extended reaction arms, or custom-fabricated systems — we provide calibration services tailored to your unique setup and requirements.
Our Hydraulic Calibration Services Include
A comprehensive multi-point verification process for every hydraulic torque system
- Calibration of torque output in relation to applied hydraulic pressure using high-accuracy hydraulic torque testers traceable to NIST
- Multi-point verification across the tool's operational range — ensuring reliable performance at low, mid, and full-scale pressures
- Inspection and functional checks of pump controls, pressure gauges, couplers, and hydraulic lines to identify issues affecting torque output
- As-found and as-left calibration certificates compliant with ISO/IEC 17025, including pressure-to-torque correlation data
- Optional configuration of custom pressure charts or lookup tables for on-site field reference
- Full NIST-traceable measurement chain for all reference standards and hydraulic test equipment used
