The potential nature of these corrosion problems makes inspection of stainless steel piping very cautious, especially in susceptible conditions. These conditions include:
Temperature (the most problematic temperatures depend on the specific steel grade and exposure level to corrosive chemicals, but are usually in the range of 50 to 300°F)
frequent exposure to chlorides
Damaged insulation
The points where carbon steel and stainless steel come into contact with each other, and
High moisture content (corrosion always requires water).
The need for inspection is even greater if the pipes under these conditions are subject to significant stress or stress. In addition, different grades of stainless steel have different specific corrosion vulnerabilities; for example, Type 304 is prone to pitting corrosion in seawater.
