Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using incorrect thread sealant for the specific media being conveyed.Consult material compatibility charts to select a thread sealant or tape that is resistant to the fluid or gas being transported and the operating temperature and pressure.
Overtightening threaded connections, leading to pipe or fitting damage.Tighten connections until they are snug and then an additional 1-2 turns, or until a secure seal is achieved, avoiding excessive force that could compromise the integrity of the threads or pipe.

Common Applications

  • Chemical Processing and Petrochemical Plants
  • High-Pressure Fluid and Gas Transfer
  • Food and Beverage Industry Piping Systems

⚠️ Engineering Warnings

  • Always verify material compatibility with the specific chemicals and operating conditions.
  • Ensure proper safety precautions are taken during installation, including the use of appropriate personal protective equipment.
