What is the pressure for the horizontal pressure test of vertical pressure vessels?
Thread Content
May I ask, if a pressure test on a vertical container has to be carried out in a horizontal position due to excessively high pressures, is the test pressure still 1.25 times the design pressure?
The hydrostatic pressure of the liquid column is added to the vertical test pressure.
The vertical test pressure is increased by the hydrostatic pressure of the liquid column, then rounded before using it for the cylinder verification
If it’s still not clear, it is recommended to consult JB/T4710 for tower-type containers
All pressure vessels should undergo a horizontal pressure test
1 meter equals one static column pressure! ! ! !
The test pressure is still 1.25 times the design pressure, but the hydrostatic pressure of the liquid column must be taken into account; therefore, the test pressure should be: PT=1.25P/+ρH.
As a supplementary note, if a pressure test is to be conducted, there should be no static liquid column pressure applied
For low-pressure vessels, it is the greater of 1.25 times the design pressure and the design pressure plus 0.1; in addition, the static pressure of the liquid column must be taken into account, as this is intended for conducting hydrostatic tests after the equipment has been installed.
