Hydraulic testing of the container

2008-01-04View Original

Thread Content

Today I read the hydraulic testing instructions for a reactor at Lurgi in Germany; it states that desalinated water is pumped into the reactor, then the pressure is increased to 10% above the design pressure to check for any leaks, and finally the pressure is reduced to complete the process. Do we only need to test it once? I remember that in the lab we used to have to do it several times. I would appreciate some advice from those who are more experienced.

Why do we need to test several times? What is the reason? The purpose of pressure testing is actually to check for leaks. When under pressure, it will leak if it’s supposed to; what’s the point of trying several times?

There is no need to conduct pressure tests multiple times; I have made purchases on several occasions and visited the manufacturer to observe the pressure testing process, and in each case it was done just once. Sometimes, after testing at the manufacturing plant, a pressure test is conducted again after the equipment is installed, taking into account the possibility that the seal might be damaged during transportation.

One pressure test is enough; it’s just to check whether there are any leaks

The hydraulic test of equipment is generally performed only once; it is considered a destructive test, and conducting it multiple times will have an adverse effect on the equipment’s service life.

Those who conduct tests usually do so only once; for those requiring airtightness, an additional airtightness test is carried out

A hydrostatic test is generally carried out only once; it is sufficient if there are no leaks within the specified pressure retention time. If a airtightness test is required, then the next testing step is carried out.

Hydraulic testing is done once, while pneumatic testing is done several times

:Lol, does a hydrostatic test pressure exceeding 10% count as destructive? ? ? ? :L

For normal operation, a hydrostatic test is usually carried out once, similar to what is done for airtightness testing

The hydrostatic test only needs to be performed once:victory: :victory: :victory:

For container pressure testing, it is carried out at the pressure specified in the design drawings in accordance with regulatory requirements. After applying pressure, it is checked whether the container leaks; it must not leak within the specified time period for the test to be considered successful. The number of pressure tests is generally not required to be high. Except in special cases.
