Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using incompatible fittings that do not meet the pressure or material requirements.Select fittings specifically rated for the pipe's pressure class and compatible with 304 stainless steel to prevent galvanic corrosion and ensure system integrity.
Inadequate cleaning of pipe ends before joining, leading to potential leaks or weld defects.Thoroughly clean and deburr all pipe ends to remove any contaminants, grease, or scale that could compromise the joint's integrity.
