Velocity Washer

Up to 30x Faster Disassembly

Velocity Washer is a patented technology designed to give you up to 30x faster disassembly. With the same assembly, torque up, and breakout procedures as standard washers, you’re not locked into a system. You benefit from reduced downtime, less manpower, and predictable time savings.

Rethink Your Disassembly

How It Works

Testimonials

“We have the Velocity Washers on two of our blowdown exchangers. We typically have to torch cut these large studs; with the Velocity Washers they spun off just like shown on the promotional videos. We re-used the studs and nuts.” – Lead Reliability Engineer

“The same reactor head after installation of Velocity Washers, took only 1-2 hours in total to disassemble, with no damage to capital equipment, no hot work needed and no studs needed replacing.” – Turnaround Planner

“Our results with the Velocity Washers were very good. Normally we would budget four 10 hour shifts of gouging. This involved a substantial hoarding and of course time. With the Velocity Washers it took us a bit over half a shift.” – Maintenance Coordinator

Advanced technology

made simple.

Velocity Washer has been designed to give maximum benefit with minimal change to the hard work you do everyday. No special tools required. No changes to your bolting procedures.

Meets ASTM F436 material specifications

Velocity Washer provides the same load distribution benefits as using a traditional hardened washer and meets ASTM F436 specification for material, hardness, and fitment.

How It Works

1. Place on Stud

To install, simply place the Velocity Washer on the stud. Due to its symmetric design, it can’t be installed in the wrong orientation, delivering the simplest installation.

2. Torque the Nut

You then torque the nut on using standard procedures: there are no special tools.

3. Turn the Nut to the Left

As always, turn the nut to the left. It will take less than one stroke of the torque wrench for the Velocity Washer™ to release all load.

4. Run the Nut Off

Once the Velocity Washer pops, all load will be removed, allowing the nut to be easily run off.

Large Capital Equipment

Imagine what Velocity Washer could do for your large capital equipment.

Sample Applications

  • Heat Exchangers
  • Reactor Manways and Blinds
  • Hydrotreaters
  • Furnace Blinds
  • Piping inlets and outlets

Ready to go

Velocity Washers are ready to go – straight out of the box. No costly engineering analysis or change of work procedures – just put them on and get it done up to 30x faster by eliminating seized nuts.

Frequently Asked Questions

Velocity Washer sizes range from 3/4” – 5” bolt diameter. Contact us for sizes outside this range. 

No, the Velocity Washers are designed to replace a standard hardened washer, so no additional tooling is needed.  

No, you only use one Velocity Washer per stud on the same side of the flange the torque wrench will be applied.  

Velocity Washers are typically designed to relieve 0.12” of bolt stretch. That is equivalent to 100% bolt yield on a 34” grip length.  

 

The load-bearing area of the Velocity Washer is greater than that of the bolt, and it is made from a stronger material. So, anything the bolt can take, the Velocity Washer can take.  

The max temp is around 850F. If we have an application that goes above 850F, we have other alloys that can take that max temperature up to 1100F safely.  

The Velocity Washers need less torque to turn than a standard bolt, so no additional torque is needed.  

Velocity Washers will fit wherever a standard washer will fit.  

Velocity Washers are typically double the height of a standard washer. We have a full spec sheet available on request.  

No vibration issues. The Velocity Washers have been tested over 30,000 cycles, applying 30 G acceleration and 15,400lbs of shaker force. The Velocity Washers passed the test. See video:

Standard Velocity Washers are made from HT4340 which has been heat-treated and stress relieved. In special circumstances, we can cut Velocity Washers in different materials based on your specific needs.  

Velocity Washers are made from HT4340, which is a stronger material than standard bolts. You will yield the stud before you damage the Velocity Washers.
