Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using pipe dope on compression fittings.Compression fittings rely on the metal-to-metal seal and do not require pipe dope. Use only on threaded connections.
Over-tightening threaded connections.Over-tightening can strip threads or damage the pipe/fitting, leading to leaks. Tighten firmly but avoid excessive force.

Common Applications

  • High-pressure fluid and gas transmission
  • Industrial process piping
  • Structural applications requiring robust support

⚠️ Engineering Warnings

  • Always verify material compatibility for the intended fluid or gas.
  • Ensure proper thread protection during handling and storage to prevent damage.
