Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Incorrectly specifying pipe schedule for operating pressure requirements.Always consult pressure-temperature charts and design codes to select the appropriate schedule (e.g., Sch 160) that meets or exceeds system demands.
Using incompatible welding consumables that compromise corrosion resistance.Employ welding electrodes or filler metal specifically designed for 304 stainless steel to preserve its inherent passivation layer and prevent sensitization.

Common Applications

  • High-pressure chemical processing systems
  • Petrochemical and refinery pipelines
  • Cryogenic fluid transport

⚠️ Engineering Warnings

  • Material compatibility with the specific process fluid and operating temperature must be verified.
  • Proper handling and storage are crucial to prevent surface contamination and maintain corrosion resistance.
