Issues regarding the piping design of screw compressors

The workshop currently has two single-screw air compressors, with an air supply pressure of 1.0 MPa and a volumetric flow rate of 20.2 m^3/min. The compressor outlet pipeline specified in the manual is DN65, which results in a flow velocity of 100 m/s – is this okay? We currently have two buffer tanks in series, with a capacity of 3.3 m^3 each; the inlet and outlet diameters of these tanks are DN100. Can they be used? I want to install a sandblasting machine. The user specified that the rated air pressure for this machine is 0.8 MPa, with an air consumption of 6.1 m^3/min and an inlet pipe diameter of DN40. Is this appropriate? I calculate that the air velocity would be quite high
It should be calculated based on the compressed volume; a volumetric flow rate of 20.2 m^3/min refers to the gas volume under standard conditions
