Hydrostatic and Pneumatic pressure testing Procedures
Safety
Chemical plant equipment such as pressure vessels, heat
exchangers, columns. Pipelines, etc., need to be inspected, such as after
completion of manufacture or install at regular intervals before commissioning
and during plant operations, such as ensuring legal regulations and safe
operation.
Testing methods are usually hydrostatic and pneumatic tests.
In addition to the rare test "helium test", pneumatic tests are also
widely used to minimize down time and economy and to facilitate testing.
Compared to which there are hydrostatic tests. It is also useful in detecting
very fine juice pathways that cannot be found in hydrostatic tests. However, it
is not as safe as hydrostatic for the reasons which are listed at the las of
this article.
Hydrostatic pressure test is a common non-destructive test
method used for testing after piping and pressure vessel construction. This
method is often preferred by the owner due to product consideration.
Hydrostatic pressure test example is hydrogen peroxide testing
for a pipe line or tank. Since hydrogen peroxide is very sensitive to
pollutants, it is best to use this method.
Hazards & Safety concerns during hydrostatic testing
However, in the safety frame, there is a potential risk in
the hydrostatic pressure test. It can cause injury and death as well as damage
to property if not handled properly.
Hydrostatic pressure test uses water at high pressure. The applied pressure is 1.5 times
