A1 level vessel certification design pressure issues
Thread Content
It is the first time to obtain evidence for a Class A1 pressure vessel, a single-layer high-pressure vessel. What is the appropriate design pressure for making samples? (That is, it is convenient for manufacturing by the manufacturer and meets the certification and audit requirements)
Just take the value according to the high pressure. Anyway, after the trial design, you need to find a design institute that can produce three types of drawings for review.
10.0MPa, lower limit of high pressure.
Is it okay to take 10MPa directly? Are there any regulatory requirements?
It doesn’t have to be such a high pressure. Just choose a special medium and a type three container.
They need to get an A1 certificate, which is a high-voltage range.
We are also getting the A1 manufacturing certificate. The design pressure is 12MPa and the buffer diameter is DN500. I plan to take over the welding structure and make it into a welded structure. I don’t know if it is feasible.
Taking 10MPa is too harsh (just kidding, don’t mind). It just reaches the high-pressure line. It is recommended to take a working pressure of 10.0 MPa and multiply it by a coefficient. The design pressure will be about 11MPa. This way, not much material will be wasted. Generally, such equipment will not be too big.
I plan to make the external connection not flange connection, but welding connection. I don’t know if it is feasible. I hope you can enlighten me.
