U-bolts are a u-shaped rod with threaded ends, that fits around a pipe and is attached to a supporting member.

The humble U-Bolt has been a staple of Operating Plants for decades so we know it is an unusual time to be launching U-Bolt innovation. However, PT&P has seen many customers struggle with issues around U-Bolts. In fact, one of the challenges is that the U-Bolt is used so often that it is difficult to get the right configuration. Some of the challenges with U-Bolts include:
Contact Corrosion – the interface of non-insulated steel piping with a U-Bolt is subject to accelerated corrosion at the point of contact. This is due to crevice corrosion which occurs due to the crevice formed next to the contact between the Pipe and base of the U-Bolt. *View more on contact corrosion
Thermal Growth Issues – PT&P has seen many U-Bolts that were not designed to accommodate the axial movement associated with thermal growth.
Corrosion of U-Bolt – certain environments can lead to accelerated corrosion of U-Bolts which are made with traditional galvanized steel.
Sizing – some customers struggle with unusual sizing requirements
Coating of U – some customers struggle with getting the right coating on the U portion of the U-Bolt
PT&P’s Super U-Bolt provides customers with solutions to these issues by providing the broadest range of options:
Vibration Energy Absorption – PT&P offers customers the option to add a Vibration Pad which converts some of the mechanical energy of Vibration to heat. A traditional U-Bolt just stiffens the piping system by causing it to resist movement. However, this does not remove the vibration energy from the system and it continues down the piping system. Vibration pads offer energy absorption of up to 80% of the mechanical energy being converted to heat! *View more vibration solutions
Eliminate Contact Corrosion with TPI – PT&P’s half-round thermoplastics limit the touchpoint between the piping and U-Bolt.
Material Customization – Customers can specify a broad range of materials including various grades of stainless and even Super Alloys.
Custom Finish on U – PT&P offers a standard plasticized finish. Custom finishes such as Neoprene can also be specified to suit particular applications.
Custom Sizes – PT&P’s unique mass customization manufacturing operation allows us to customize sizes far more easily than any other provider. *View more on customization

Allowance for Axial Movement – If axial movement is desired, PT&P can provide a configuration that offers a low coefficient of friction. Options include PTFE coating or TPI.
