Water Requirements for Hydrotest

[Manish Kumar]

Dear Sir,

I want to know that which type of water is used for Hydrotest in stainless steel piping and equipment. Please advise as per relevant code and standard.

[Vishwas Keskar]

use water with Chloride content less than

 25 ppm

use potable water

do water analysis

Hi!

It should be.less than 25 ppm

It also depends upon service application of.eqpt.and concern spec

Generally.kept below 25ppm

Dear , 

As follow saudi aramco standard and procedure ,  saes-a-004, saes-l-150, following are my observations

Water used for hydro testing of stainless steel piping systems shall have chloride content value less than 50ppm, and PH value should be 7.5, ±.5.

Water used for any part of the hydro testing or subsequent lay-up shall have a sulfate reducing bacteria (SRB) count of 10³ per ml or less

When the equipment contact time with hydrotest water may exceed 14 days, an approved oxygen scavenger shall be added to the hydrostatic test water.

For stainless-steel piping, the duration of the hydro testing (using water with less than 50 ppm of chlorides), flushing and draining-drying sequence shall be kept as short as possible, in order to reduce the possibility of chloride attack. Water testing certificate will be made available for each hydro test

regards 

Dhaneesh
