Hydraulic volumetric expansion test. The hydraulic pressure is equal to times the design pressure. The elastic expansion is measured between the test pressure and 10% of the test pressure. The vessel is rejected if the elastic expansion is more than 110% of the most recent qualifiion or production burst test.

Re: what is the Max. Nitrogen gas pressure in accumulator for vertical roller mill hydraulic cylinder. Dear Arman, N2 depends mainly on your operating grinding P. Most probabily 2 problems will happen with very low or high N2 Press exceeding limits. 1. Mill will be having abnormal vibration behaviour. 2.

With a universal rolling mill, when being applied primarily at the finishing stage of shaping, if the rolling speed is fast and the amount of pressure under the flange is not that big, there is slipping that occurs between the material and the vertical roll before the material undergoing rolling bites into the roll, and the vertical roll synchronizes with the rolling speed and begins turning.
