Why are the design pressure and operating pressure of the Shenjiang gas storage tank the same?
Thread Content
The nameplate of the Shenjiang gas storage tank we purchased indicates a working pressure of 0.8 MPa, and its design pressure is also 0.8 MPa. Why is that? Has anyone encountered the same situation?
If that is the case, then how is the opening pressure of the safety valve determined?
The design pressure can be equal to the maximum operating pressure.
The design pressure is greater than or equal to the maximum operating pressure. Equal is also fine.
It has been clarified that it was the engineer on site who failed to check properly; the operating pressure is 0.8 Mpa, the design pressure is 0.88 Mpa, and the setting pressure of the safety valve is 0.84 Mpa. Generally, when the compressor outlet pressure is 7.5 bar, is it sufficient to use an air tank with a working pressure of 0.8 Mpa? Is it necessary to raise it to 1.0 Mpa? What if three stages of filtration and a heatless regenerative dryer are added before entering the buffer tank?
Generally, the compressor outlet pressure indicated on the air compressor’s nameplate is absolute pressure, while the operating pressure in the air tank is gauge pressure. Pay attention to the relationship between the two; just perform the conversion accordingly: lol. Your first configuration doesn’t have many issues, while the second one is safer! Is the air compressor from Atlas?
How did they know it was Atlas upstairs?
^_^ Well, it’s experience, lol: Atlas air compressors are usually equipped with storage tanks made by Shanghai Shenjiang, unless the user provides their own tanks or hires someone else to manufacture them.
The Shenjiang storage tanks I’ve come across seem to have an operating pressure of 0.8 Mpa, with a maximum operating pressure of 0.84 Mpa.
I called Shenjiang directly and they told me that the operating pressure is 0.8 Mpa, the design pressure is 0.88 Mpa, but the value indicated on the equipment’s nameplate is 0.84 Mpa. I’m not sure why
To determine the exact pressure, it is still necessary to refer to the original drawings of the compressor.
