Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using standard fittings not rated for the high pressure of Schedule 160.Always select fittings specifically designed and rated for the corresponding pressure class of Schedule 160 pipe.
Inadequate cleaning of pipe ends before welding or joining.Thoroughly degrease and remove any oxidation from the pipe ends to ensure a strong, leak-free connection.

Common Applications

  • High-pressure fluid transfer in chemical processing
  • Subsea oil and gas pipelines
  • Sterile fluid transport in pharmaceutical manufacturing

⚠️ Engineering Warnings

  • Not suitable for applications involving high-velocity abrasive fluids without specialized consideration.
