What diameter for compressed air?

What diameter for compressed air?

If the hose is too long or too narrow, the pressure leaving the compressor may drop when arriving at the gun. It is important to use a hose with a diameter of at least 0.65 cm. One diameter of 0.8mm or 0.9mm is recommended.

Which tube for compressed air?

The tubing ofpressurized air aluminum are the best solution to most industrial applications. These tubing ensure that you have virtually no pressure drop.

Which pipe for an impact wrench?

For the use of a impact wrencha chipping hammer or other device with high air consumption, you must use a pipe of air with an internal diameter of 10 to 12 mm, connect it to the direct outlet of the compressor tank and imperatively use all along the connection chain of the tips and …

How to calculate the nominal diameter of a pipe?

This nominal diameter is deduced according to the flow rate of the fluid to be conveyed and the admissible speed in the pipe. Often another parameter can intervene, it is the loss of load (evolving with the square of the speed). Steam condensates < 1 m/s Note that in the case of industrial pipes, the flow is considered to be continuous.

What is the maximum velocity of a fluid in a conduit?

The maximum speed of a fluid in a conduit is therefore determined by the pressure drop it causes. This “allowable” pressure drop so that the duct is not noisy or generates additional operating costs (energy and pumping) must remain less than 20 mm/m of linear pressure drop. (for liquids)

How to calculate the DN of a steam line?

c) Consider a pipe delivering steam at a rate of 2000 kg/h at an effective pressure of 15 bar and at a temperature of 325°C. Starting from the t° (325°C) via the effective pressure, the mass flow rate and the flow velocity, we obtain the dn = 155 mm or the normalized dn = 200 mm.

What is the diameter of a duct?

The diameter of the ducts is generally the desired dimension. For non-circular ducts, with rectangular or oblong sections, the equivalent diameters, isokinetic diameters or hydraulic diameters are used.
