Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using standard wall thickness pipe for high-pressure applications.Always verify the required schedule (e.g., Schedule 80) based on system pressure, fluid type, and operating temperature to ensure adequate safety margins.
Inadequate bevel preparation for welding.Ensure precise bevel angles and consistent root faces are achieved to facilitate proper weld fusion and prevent defects.

Common Applications

  • High-pressure hydraulic systems
  • Steam and process piping
  • Structural supports in heavy industrial settings

⚠️ Engineering Warnings

  • Ensure compatibility of pipe material with transported fluid to prevent corrosion.
  • Adhere strictly to all relevant ASME and API codes for installation and welding to guarantee safety.
