Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using incorrect pipe sealant for the application (e.g., gas vs. liquid, specific chemicals).Consult the sealant manufacturer's compatibility chart for the specific fluid, temperature, and pressure of the system.
Over-tightening or under-tightening threaded connections, leading to leaks or thread damage.Adhere to recommended tightening procedures for the specific pipe size and fitting type. Use two wrenches for leverage, one to hold the fitting and the other to turn the pipe.

Common Applications

  • High-pressure fluid transport
  • Oil and gas exploration and refining
  • Chemical processing plants
  • Steam and hot water distribution

⚠️ Engineering Warnings

  • Always consult relevant industry codes and standards (e.g., ASME B31.3) for specific application requirements.
  • Ensure compatibility of pipe material with transported fluids to prevent corrosion or degradation.
