Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using incorrect threading compound or sealant for the application.Consult material compatibility charts and select a sealant or compound specifically designed for carbon steel and the transported medium.
Over-tightening threaded connections, leading to stress cracks or deformation.Tighten connections until snug, then an additional 1/2 to 1 turn as recommended for the specific fitting type and thread size. Avoid excessive force.

Common Applications

  • High-pressure fluid and gas transmission
  • General industrial piping systems
  • Structural components in corrosive environments

⚠️ Engineering Warnings

  • Always wear appropriate personal protective equipment (PPE) during handling and installation.
  • Ensure compatibility of the transported fluid or gas with carbon steel before installation.
