How is the test pressure determined in a hydraulic test?
Thread Content
Should the test pressure in a hydraulic test take into account the static pressure of the water column?
Please refer to the specifications: Section 7, Pressure resistance test and airtightness test, as well as test pressure 3.8.1 in GB150. Is it possible that your tower is placed vertically for the hydraulic test? It seems unlikely, oh~~~
Hehe, it’s a horizontal test. If it were vertical, would we need to take into account the static water pressure? I’ve read a lot of material on hydraulic testing, but I haven’t seen any mention of the need to take into account the static pressure of the water column I hope everyone can give more suggestions. Thank you in advance!
As stated in Note 3 of 5.4.1.1 on page 11 of JB/T4710-2005: “Note 3: During horizontal testing, the test pressure should include the hydrostatic pressure of the liquid column.” For vertical testing, this hydrostatic pressure does not need to be added; however, in the technical specifications for the container provided in the detailed construction drawings, both vertical and horizontal testing conditions should generally be indicated. When performing calculations, strictly speaking, the design pressure for the nozzles and reinforcements of the tower should include the hydrostatic pressure of the liquid column.
The design drawings usually specify requirements, which include horizontal and vertical pressure testing; the required test pressures differ as well
When conducting a pressure test on a bedroom previously, the static pressure of the liquid column was taken into account, as well as the conditions during operation. For components that are subjected to the weight of the liquid, the static pressure of the liquid column should be included in the design pressure when performing calculations
The design pressure should include the static pressure of the liquid column during operation. The hydrostatic test pressure must take into account the static pressure of the water column, whether it is in a horizontal or vertical configuration.
For vertical containers under horizontal water pressure, the static pressure of the water column should be taken into account. Vertical towers and vertical heat exchangers are considered in this way
I saw today that if the pressure test pressure is greater than 5% of the design pressure, static pressure needs to be taken into consideration. I’m not sure if this is true; I’d like to learn more about it. I’m a newcomer, and I hope everyone will help me in the future. Thank you. This post was last edited by cuicunzhi on 2009-2-17 at 22:16
