Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using incorrect thread sealant for the transported medium.Always select a thread sealant specifically rated for the fluid or gas being conveyed and the operating temperature and pressure.
Over-tightening fittings, leading to potential pipe or fitting damage.Tighten fittings firmly until resistance is met, then an additional quarter to half turn is usually sufficient. Avoid excessive force.

Common Applications

  • Hydraulic systems
  • Steam lines
  • Water distribution
  • General plant piping

⚠️ Engineering Warnings

  • Ensure compatibility of the carbon steel material with the transported media to prevent corrosion.
  • Always adhere to relevant ASME B31.1 or B31.3 piping codes for installation and service.
