How to maintain pressure in a spherical tank
Thread Content
How can a spherical tank maintain a pressure of 1.0~1.5 Mpa? Is there any loss when the spherical tank is stored at room temperature? (I usually see water droplets on pipeline spheres.) Waiting online~ Thank you
The spherical tanks in our facility are subjected to pressure retention tests before use, and they are only put into operation after passing these tests. It shows no loss when stored at room temperature, unless the safety valve is not tight.
Liquid ammonia – it’s normal, as there is a considerable amount of it; normally, there is no loss.
Liquid ammonia has a saturated pressure corresponding to its temperature; the pressure is generally regulated by controlling the release of non-condensable gases. If a lower target pressure is required, an ice machine may be necessary. Another factor is the impact of temperature, which cannot be ignored, especially in summer and winter.
