Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using the wrong threading compound for the specific media or temperature.Consult material compatibility charts and select a threading compound rated for the operating conditions of the fluid and the 316 stainless steel.
Overtightening threaded connections, which can crack fittings or damage pipe threads.Hand-tighten connections first, then use a wrench for a limited additional turn (typically 1-2 turns) to achieve a seal without excessive force.

Common Applications

  • Chemical Processing and Petrochemical Industries
  • Marine and Offshore Applications
  • High-Pressure Fluid and Gas Transfer Systems

⚠️ Engineering Warnings

  • Ensure proper handling to prevent scratching or damaging the pipe surface, which could compromise corrosion resistance.
  • Verify compatibility of all associated fittings and sealants with 316 stainless steel and the intended service conditions.
