The idea that something as solid as a stud or bolt may also serve as a spring is challenging to fathom if you’re holding one. It is precisely what a bolted joint’s fasteners perform. When assembled, they need to be pulled taut with sufficient power to maintain a tight grip on the joint once it’s in use. The joint can give way when the stud loads are uneven, too low, or excessively heavy. Read below to know more on hydraulic bolt tensioner.

Tensioners, hydraulic studs, and bolt tensioning devices are easy and effective solutions. Using this tightening approach, you may manage the substantial expenses caused by improperly fastened studs. Contact HTI to learn more about the various uses of hydraulic tensioners and why they are the best option for your equipment.

Tightening bolts hydraulically offers:

• Precision – exceptional accuracy within the bolt load tolerance range, often 5% or higher. Lubrication is unnecessary, and there are no losses from friction to worry about. Transferring load and overload prevention are both made easy.
• Quickness – Installing and using the tools is a breeze.
• Concurrent straining – Activating numerous bolt tensioners simultaneously hydraulically is possible.
• Consistency – Tensioning many bolts simultaneously ensures that each bolt is subjected to the identical applied load.
• Protection – no sensitive areas or problems with responses. Boltight solutions are more secure than standard industrial practices.
• Flexibility—It is common practice to use adapter kits so that a single tensioning kit can accommodate a wide range of bolting sizes.
• Economy of scale—When all of the considerations mentioned above are considered, the hydraulic tensioning tool provides the client with operational benefits.

Advantages of Hydraulic Stud and Bolt Tensioning Devices and Tensioners:

Reliable Stud Loading Every Time:

Tightening using hydraulic tensioners, stud yet bolt tensioners, and similar tools is conceptually and practically straightforward. One kind of hydraulic cylinder is the hydraulic stud tensioner.

A stud’s tension is proportional to the hydraulic cylinder’s area plus the pump’s pressure within it. Stud tensioning is spot on because we have tight control over these factors.

Loading and tightening studs consistently and adequately has never been easier than with hydraulic tensioners.

Thinning Out Studs:

It is vital to ensure that each stud is loaded evenly when using gaskets. HTI suggests using several hydraulic stud tensioners when a single stud is involved.

An internal connection exists between the pump’s shaft and these hydraulic tensioners. When hydraulic pressure rises, flanges come together uniformly and identically because stud tension is constant.

Effort Reduction:

Collaborative operation of many hydraulic stud tensioners reduces operating time. In most cases, hydraulic torque wrenches are slower than hydraulic tensioners.

One Hydraulic Tensioner for each of the four studs on the flange, or “25% cover,” will usually reduce the tightening time by fifty per cent (50%) compared to torque.

A further one-third (or 33% reduction) in time is possible with a “50% cover” or one Hydraulic Tensioner for every two studs.

User-Friendliness and Security:

The power-to-weight ratio is relatively high for hydraulic tensioners, studs, bolt tensioners, and similar tools. These tools have advantages over torque tools, including being simpler, smaller, and lighter. A single operator can operate most applications with little effort.

Separate from one another, the operator controls the hydraulic tensioner’s load cell, puller bar, and bridge. For identical stud sizes and tightening capacities, the combined weight of the hydraulic wrench and socket is sometimes much higher than that of either one of these components.

Hydraulic studs and bolt tensioners are safer to operate than noisy slugging wrenches or bolt warmers. Air or manually controlled hydraulic pumps can never explode.

Prolonged Life of Studs:

Thread galling and seizing are obsolete because hydraulic stud tensioners prevent galling by reducing the contact pressure between the threads and the nuts’ exteriors.
