Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using incorrect fittings not rated for 316 stainless steel or the operating pressure.Always select fittings specifically manufactured from 316 stainless steel and designed for the intended pressure and temperature rating of the piping system.
Inadequate cleaning of pipe ends, leading to compromised weld or thread integrity.Thoroughly clean and deburr all pipe ends to remove contaminants, oils, and any surface imperfections that could affect the joint's strength and sealing capabilities.

Common Applications

  • Chemical processing and handling
  • Offshore oil and gas exploration
  • Marine environments and shipbuilding
  • High-purity fluid transfer systems

⚠️ Engineering Warnings

  • Always consult relevant industry standards and codes for installation and application guidelines.
