Hydro test pumps are common
procedure used to check fluid pressure
vessel, such as, cylinders, boiler, tubes
pipe, valves, castings, components etc..
Hydrostatic pressure testing is also a
common testing procedure to verify pressure
vessels do not leak or have manufacturing
flaws. Hydro test pumps
& unit is important for pressure vessels
in the interest of device safety, and
durability under operating pressure.
The pressure
vessel to be tested is located within a
sealed vessel. The sealed vessel is filled
with a incompressible fluid, typically water
or oil. The pressure test vessel is
then subjected to a known internal pressure
for a known duration. The known internal
pressure is normally a significant percent
greater than the maximum operating pressure
of the device (typically 150%). The applied
pressure causes the test vessel to expand,
instrumentation, which is already in place,
are then read to determine the total and
permanent expansion that the test chamber
(external) undergoes. A physical and visual
inspection then follows the Hydro test pumps to determine that the
device being tested has not been damaged or
permanently distorted due to the test
pressure.
Pressure vessels
may be re-verified by subjecting the vessel
device to a proof-pressure test. The
proof-pressure test is commonly referred to
as a "modified hydrostatic test". The
pressure vessel is subjected to a known
pressure for a predetermined time. During
and following the proof-pressure test, the
pressure vessel is inspected for abnormal
distortion or failure.
PressureJet also
offers Hydro test pumps
with pre-filling cum pre-pressurizing cum
pressure building system. For large volume
of hydro test
combine hydrostatic
pressure testing unit is most
preferred solution. This hHydro test pumps & equipment is
compact, efficient & cost effective,
available in different combinations of
pressure and flow. The unique
automatic hydro test
controller is a standard
feature of this system.Otherwise also for
large quantity, automatic hydrotest
controller is very useful to improve
productivity thru even a kay man.
Though
theoretically water is considered as non
compressible fluid, it requires considerable
amount of feeding to raise the pressure.
“How much water
is to be injected to raise certain
pressure?” and “What time will it take to
reach up to desire pressure?” are typical
questions, asked by majority customers who
are inquiring about high pressure
hydrotest pumps. It depends upon the
following
- Initial
pressure from which we start feeding the
water
- Total
Volume of the equipment
- Required
pressure for the testing
- Time
available in minutes/ hours.
Customer should
furnish the above information and leave it
to us for the right selection of
hydrotest pumps.
We have wide
range of hydraulic pressure testing
machine, of different test pressure.
We would like to
inform you that pressureJet technical team
is well trained to select right (here,
optimum) hydrotest pump for right
application. Therefore, rest assured that
they will never mislead you.
