Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using standard fittings not rated for Schedule 160 pressure.Always specify and use fittings explicitly rated for Schedule 160 or higher pressure and compatible with 316 stainless steel.
Inadequate weld preparation or filler material for 316 stainless steel.Follow strict AWS D1.6 or equivalent welding codes for stainless steel, ensuring proper joint beveling and using appropriate low-carbon or stabilized filler metals.

Common Applications

  • High-pressure fluid transfer systems
  • Chemical processing pipelines
  • Offshore oil and gas exploration

⚠️ Engineering Warnings

  • Ensure compatibility with all media and operating temperatures to prevent premature corrosion.
  • Verify that all welding and fabrication procedures meet the stringent requirements for high-pressure, corrosive service.
