A U bolt is a fastening device commonly used in plumbing to secure piping or tubing. Characterized by its U-shape, it is typically threaded at both ends, allowing it to clamp onto pipes or tubes effectively. This design ensures the pipes or tubes are held firmly in place, preventing movement or shifting.
While U bolts are straightforward to install, care is needed in environments with vibration. To prevent loosening or shifting, appropriate vibration-absorbing materials, nuts, or additional vibration countermeasures should be used.
U bolts have a wide range of applications, particularly in:
They are used to secure piping to walls and floors in buildings and factories, providing stability and reinforcement at specific points or junctions.
U bolts are also employed for suspending long pipes and tubes from ceilings and beams, ensuring stable support.
In vibration-prone environments, U bolts play a critical role in preventing misalignment and loosening, often used with vibration absorbers and cushioning materials.
The effectiveness of U bolts lies in their U-shaped geometry and the mechanical properties of their threads. The U shape allows the bolt to encircle a pipe, providing stability, while the threaded ends can be tightened to secure the pipe firmly. Applying the correct torque ensures the U bolt clamps the piping securely.
U bolts are typically made of materials like SS400 with zinc plating or SUS, and are compatible with various piping materials.
Key considerations when choosing a U bolt include:
Measure the outside diameter of the pipe accurately to ensure a snug fit with the U bolt's inside U-shaped portion.
Choose a U bolt that can handle the load and environmental conditions where it will be used. Heavy loads and harsh conditions require stronger materials.
Consider the material and anti-corrosion treatment of the U bolt, especially in humid or corrosive environments.
While hanging bands and other methods are available for fixing piping, U bolts are preferred for heavy piping or in environments with vibration. However, caution is advised when fastening plastic piping or heat-expanding pipes like steam piping. Additionally, using steel U bolts on SUS supports and piping may lead to dissimilar metal corrosion.
