Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using incorrect sealant for the specific fluid or gas being conveyed.Consult the material compatibility charts for 304 stainless steel and the process media to select a sealant that provides robust chemical resistance.
Inadequate cleaning of the pipe ends prior to welding, leading to weld defects.Ensure all mill scale, oil, and contaminants are completely removed from the weld bevel and surrounding area using approved cleaning agents and methods.

Common Applications

  • Chemical processing pipelines
  • Petrochemical fluid transfer systems
  • High-pressure steam lines

⚠️ Engineering Warnings

  • Verify compatibility of the 304 stainless steel with the specific process fluid and operating temperature to prevent corrosion.
  • Adhere strictly to welding procedures and post-weld heat treatment recommendations to maintain material integrity and prevent sensitization.
