Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using incorrect joining methods for the specified pressure rating.Always consult system pressure requirements and employ welding or mechanical joining methods certified for Schedule 80 pipe and the operating conditions.
Failing to adequately support the pipe during installation, leading to stress concentration.Ensure adequate pipe supports are installed at recommended intervals to prevent sagging and reduce stress on joints and the pipe material.

Common Applications

  • High-pressure hydraulic lines
  • Oil and gas exploration and processing
  • Chemical processing and transfer

⚠️ Engineering Warnings

  • Ensure compatibility of fluid or gas with carbon steel to prevent corrosion or material degradation.
  • Always follow safety protocols during cutting, beveling, and welding operations.
