CONTROLLED BOLTING TOOLS

THE RIGHT BOLTING TOOL PERFORMS EVERY TIME

 
 
Torque wrenches apply force onto a nut to cause rotation around a bolt. A hydraulic torque wrench, when coupled with a specially designed torque pump, creates the torque output, or torque load, necessary to create the clamping force to securely fasten the threads of a nut and bolt for a leak free joint.
Hydraulic torque wrenches have come a long way since they were first introduced in the early 1960s. Advancements in technology over the years have led to a full spectrum of torque wrench options.
 
The Reliable Choice for Industrial Heavy Use
When performing maintenance on an offshore oil rig or for repetitive, heavy-duty bolting applications, operators depend upon torque wrenches that work reliably every time. The ATEX-certified Enerpac S&W torque wrench series, in either square drive or hexagon low profile, are made of steel for the reliability heavy duty applications demand.

The 2-in-1 General Purpose Choice for Moderate Use
When your torque applications often take you from one type of application to the next, the most practical choice is a general-purpose torque wrench that is compatible with square drive or hex cassettes. The Enerpac RSL torque wrench series is a steel, 2-in-1 design making it more durable than aluminum options.

The 2-in-1 Modular Choice for Moderate Use
Torque wrenches compatible with interchangeable square drive or low-profile cassettes make it easy to enhance your tool inventory in a cost-effective way. The modular design of the ATEX-certified Enerpac HMT series reduces the need to purchase separate tools for those who use cassettes from a variety of leading brands. The combination of superior alloys makes it one of the most durable wrenches in its class.

The Basic Choice for Moderate Use
Aluminum torque wrenches are the preferred option for those that appreciate a slightly lighter weight tool. The Enerpac DSX series is a square drive design with an optimized weight-to-output ratio and unique safety features to prevent dropped objects and operator fatigue. This model series is also ATEX certified.

Torque Multipliers
A torque multiplier adds extra power to your heavy duty or repetitive torque applications by increasing the output torque. General use torque multipliers - either pneumatic or manual – or specialized torque multipliers for the aerospace industry are all designed for precision, safety and productivity.
 
Manual Torque Multipliers
A hand-operated tool, the Enerpac E-Series manual torque multipliers are a portable and lightweight solution when electricity or compressed air is unavailable. The planetary gear set achieves high output torque from low input torque.
E-Series Manual Torque Multipliers
 
 
Pneumatic Torque Multipliers
The Enerpac pneumatic PTW-series torque multipliers tackle the toughest bolting applications, yet they are simple to use. Designed for speed and control, the PTW-series is a continuous rotation design for constant, controlled torque output. Ideal for mining equipment wheel or shovel maintenance, turbine installations or maintenance, oil and gas pipe flanges, manway covers and much more.

While torque wrenches and tensioners work to accomplish the same objective – to clamp nuts and bolts together for joint integrity – tensioning stretches the bolt rather than torque rotation. Tensioning creates a more accurate load typically required on larger bolts.
Specialized bolt tensioners are often used in joint assembly or joint separation and controlled tightening during maintenance outages for large installations such as subsea pipelines, wind turbine foundations or gas turbine coupling units in power stations. In these types of unforgiving environments, bolting specialists rely on bolt tensioners they can trust.
 
Topside Bolt Tensioners
For most standard or compact flanges, the HydraMax topside tensioners generate 30% more load capacity than traditional tensioners. While the Enerpac GT-Series tensioners provide accurate and reliable performance in a universal and multi-use tool.

Multi-Stud Tensioners
Steam or gas turbine rotor assembly or the loosening and tightening of manway covers or inspection ports in nuclear facilities call for the tensioning of every single stud in a joint assembly simultaneously. The Enerpac MST Multi-Stud tensioners accurately pre-load all studs and reduce bolting time by as much as 75%.

Nuclear Tensioners
Recognizing the need to reduce critical path time in nuclear power plants and lessen manpower requirements and their associated dose, operators rely on tools specifically designed to minimize safety risks. The Biach Electric Stud Drive Tool (ESDT) protects workers from the dangers of absorbing breakaway torque during stud rotation. And the Biach Self-Contained Tensioner (SCT), with its quick latch and unlatch design, shortens tensioning time on reactor pressure vessel (RPV) head studs for greater safety.
