Top Side Bolt Tensioners

Top Side Bolt Tensioners

Bolt Tensioning Tools are used extensively across many industries where bolt load accuracy is critical. As bolts increase in size, the load critically increases, and operators are faced with the challenge of ensuring bolt load accuracy. When tightening a bolt by any method, the operator is aiming to achieve the correct bolt elongation. Due to friction, this can be difficult to accurately control when using traditional torque tightening methods. Prime Tools introduce different type of latest technology and advanced hydraulic bolt tensioning Tools that permanently eliminate the risk of loose or over tightened bolts. These Tools are used in variety of application like Pipeline flanges, Heat Exchangers, Pressure vessels, Compressor covers, Boiler feed pumps Wind mills and many other.

Features of prime top side bolt tensioners

  • Maximum working pressure 1500 Bar / 21755 PSI
  • Automation feasible and can be used for critical applications
  • Versatile Design: PBT Series standard top Tensioners are designed to provide few stud sizes covering from 3/4" to 5.3/4” inch and (M-16 to M-150) in mm. Different stud sizes are accommodated by simply changing the adaptor kit consisting puller, bridge and nut driver keeping same load cell.
  • High Strength Alloy Steel: PBT Tensioners are manufactured from High strength alloy steel as it is operated at max pressure of 1500bar for long lasting trouble-free performance.
  • Multi Tensioning: PBT series Tensioners can be connected and simultaneously operated by using high pressure link hose. This ensures equal elongation of all bolts in single cycle.
  • Floating Piston: PBT has the unique piston design allows 2° tilt without any loss of load, it’s prevents piston bore damage.
  • Safety in Piston stroke: PBT series while tensioning even of over stroke the high-pressure fluid will be release from the inner side of load cell saving operator from any protentional exposure.
  • High accuracy and repeatability
  • Can be used with Air operated / Electric operated pumping units or Hand pumps.

Frequently Asked Questions

What is a top-side bolt tensioner?

+
A top-side bolt tensioner is a hydraulic tool particularly used to apply tension directly to bolts.

What are the advantages of using a top-side bolt tensioner?

+
There are several advantages of using this as it ensure uniform bolt tension, reduces operator fatigue and increases the reliability and safety of bolted joints.

In which type of industries are top-side bolt tensioners commonly used?

+
These tools are commonly used in industries like oil and gas, power generation, petrochemical plants, construction, and heavy machinery maintenance.

Can top-side bolt tensioners be used in confined spaces?

+
Yes, absolutely. There are many top-side bolt tensioners that are compact and designed to be used in areas with limited access.

How do I choose the right top-side bolt tensioner for my application?

+
You may choose the right bolt tensioner depending upon the bolt size, load requirements, working space, and hydraulic pressure specifications.
