Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using incorrect threading compound for the fluid medium.Always select a threading compound specifically rated for the type of fluid and operating temperature the pipe will handle.
Over-tightening or under-tightening threaded connections.Follow recommended torque specifications or use the 'hand-tighten plus turns' method for each specific fitting to ensure a proper seal without damaging threads or the pipe.

Common Applications

  • High-pressure hydraulic lines
  • Structural supports in demanding environments
  • Chemical processing fluid transport

⚠️ Engineering Warnings

  • Ensure compatibility of pipe material with transported fluid to prevent corrosion.
  • Always follow proper safety protocols when working with pressurized systems.
