The proof pressure test bench is the static condition testing machine. The upper part of the HSU Assembly i.e. N2 gas chamber is partially filled with oil and partially with N2 gas. This chamber has to withstand pressure of upto 1000 bar in extreme condition. To test this condition of the N2 bottle, proof pressure test bench is used. The test bench gives the 1000 bar pressure in a static condition and check for the problem if any.
It is used for testing bottle the upper part of HSU Assembly. The chamber is partially filled with oil and partially N2 gas, and tested at 1000 Bar
