Tubes with an outer diameter of 0,2 m or more and made from any of the following materials: Stainless steels with 23 % chromium or more by weight; Stainless steels and nickel bases alloys with a 'Pitting resistance equivalent' number higher than 33. Technical Note: 'Pitting resistance equivalent' (PRE) number characterises the corrosion resistance of stainless steels and nickel alloys to pitting or crevice corrosion. The pitting resistance of stainless steels and nickel alloys is primarily determined by their compositions, primarily: chromium, molybdenum, and nitrogen. The formula to calculate the PRE number is: PRE = Cr + 3,3 % Mo + 30 % N
