Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Overtightening without proper torque wrench application, potentially deforming the pipe or bolt.Utilize a calibrated torque wrench to adhere to specified torque values for the given thread size and application load.
Using incorrect thread pitch or size for the application, leading to loose or insecure fastening.Verify that the 1/2"-13 thread size is compatible with the chosen mounting hardware and application requirements.

Common Applications

  • Marine and offshore piping systems
  • Chemical processing and storage
