Re: [MW:12503] SS 316 L VESSEL HYDROTEST WATER QUALITY

Hello Mr.Lassaad,

 

Find the below requirement from Saudi Aramco Material System Spec 32-SAMSS-004 for your query...

 

16.3.9     Water used for pressure testing shall be potable.  For vessels manufactured from stainless steel, the water shall not contain more than 50 ppm chlorides with pH value of 10 to 11 at the time of filling the vessel.

16.3.10   The temperature of the water during hydrostatic testing shall be maintained at not less than 17°C throughout the testing cycle.

I think this will help you...

Our 2 vessels are in SS 316L with operating temperatures respectively 21°C and -5°C
