Installation Procedure

1. Position the U-bolt around the pipe, ensuring the pipe is centered within the curved section. 2. Place the provided mounting plate or saddle beneath the pipe, aligning the plate's holes with the U-bolt's threaded ends. 3. Secure the U-bolt by threading the nuts onto the ends until firm. Tighten evenly to prevent pipe distortion.

Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using excessive force to tighten, potentially deforming the pipe or the U-bolt.Tighten nuts gradually and evenly, using a torque wrench to adhere to recommended torque values for the specified thread size and material.
Selecting a U-bolt with insufficient inside width or length for the pipe and insulation.Accurately measure the outer diameter of the pipe, including any insulation, and confirm the U-bolt's inside dimensions (A and B) are adequate for a snug but not overly compressed fit.

Common Applications

  • Marine piping support
  • Chemical processing plant infrastructure
  • Offshore oil and gas platforms

⚠️ Engineering Warnings

  • Ensure compatibility of brass with the fluid or environment being conveyed to prevent chemical degradation.
  • Do not exceed the load-bearing capacity specified for this U-bolt to prevent structural failure.
