Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using incompatible welding consumables leading to reduced corrosion resistance.Always use AWS ER316L or equivalent filler metals when welding 316 stainless steel to maintain optimal corrosion properties.
Improper support spacing leading to excessive pipe deflection or stress.Consult ASME B31.3 guidelines for appropriate pipe support spacing based on pipe size, material, and operating conditions to prevent undue mechanical stress.

Common Applications

  • Chemical Processing Piping
  • Marine and Offshore Systems
  • Food and Beverage Transfer Lines
  • Pharmaceutical Manufacturing
