Detection of chloride ion content in water used for pressure testing
Thread Content
The company is located inland, and the water used for pressure testing is urban drinking water; could the chloride ion content be above the standard? The Special Inspection Agency requested a test report on the chloride content in the water used for testing, but the local testing laboratory does not provide such testing services – what should be done? ? ? Dear everyone, feel free to leave a message
With coordinates along the coast, essentially each project requires a chloride ion test report, and such reports are available. In inland areas, if they are saline-alkali regions, the chloride ion level might also be too high, right?
Ask the relevant local agencies how they handle it
The chloride content in the tap water is above the standard; I’ve never seen it exceed the limit before, but tests have indeed shown this. Even austenitic stainless steel is cleaned with ordinary water, and then blown clean. It’s mainly to test the strength; as long as it’s strong enough, that’s fine. However, only austenitic stainless steels require control of chloride content; there are no such requirements for others. If you insist on having a test report for chloride ions, there’s nothing you can do about it – after all, you need to adhere to a commitment to excellence in work. It’s almost impossible to get water that is just of acceptable quality.
I’ve seen stainless steel equipment that has just been purchased, using tap water; after three months, rust forms on the surface where water accumulates and in its vicinity.

The water used in the processing process is bound to exceed the specified standards; go to a hospital and take a look at the bottom of their sterilization equipment – over time, rust forms in those areas where water accumulates. Moreover, the doors are made of cast iron, and they are covered in rust as well. What is in contact here is only water vapor; there is no direct contact with water.

The tap water definitely exceeds the standards. What is used to disinfect pools?!
There are plenty of places to conduct tests. Petroleum and chemical enterprises as well as water treatment plants should have corresponding testing departments. Make a few more calls and pay a little money
This needs to be tested; generally, tap water does not meet the requirements
As long as you’re willing to pay, it should be possible to find a testing facility; the key issue is where to find water that truly meets these requirements. According to national standards, it’s necessary to drain and dry the water thoroughly after the testing is completed.
