Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using incorrect pipe schedule for the intended pressure rating.Always consult the design specifications and relevant pressure/temperature charts to select the appropriate pipe schedule (e.g., Schedule 80) that meets or exceeds service requirements.
Failure to properly prepare pipe ends for connection.Ensure pipe ends are square, clean, and accurately beveled according to the chosen joining method (welding, threading) to guarantee a sound and leak-proof joint.

Common Applications

  • High-pressure hydraulic systems
  • Oil and gas exploration and transportation
  • Chemical processing plants
  • Power generation steam lines

⚠️ Engineering Warnings

  • Maximum allowable working pressure must be determined based on material properties, temperature, and applicable codes/standards.
  • Ensure proper handling and storage to prevent damage to pipe ends and coatings, which could compromise integrity.
