Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using incorrect thread sealant for the conveyed medium.Consult material compatibility charts to select a sealant resistant to the fluid or gas being transported.
Over-tightening threaded connections, causing stress or damage.Tighten connections until snug, then apply an additional 1/2 to 1 full turn, or follow manufacturer's torque specifications.

Common Applications

  • High-pressure fluid transport
  • Gas distribution systems
  • Steam lines
  • Structural supports

⚠️ Engineering Warnings

  • Ensure proper grounding when welding or cutting to prevent static discharge.
  • Handle with care to avoid damage to the pipe ends, which can compromise sealing.
