l How to choose a rotary union?

Many parameters related to the rotating system will help you choose a rotary union.

The first criteria it’s important to consider is  the media the union will be used for. It can be used for gas, air, vacuum, water, oil, steam, cooling liquid etc. Fitting materials should be selected according to the possible presence of abrasive or corrosive agents.

The number of passages necessary for the union, the rotational speed, the pressure in your installation and the operating temperature will allow you to calculate the size of your rotary union.

Lastly, if you need to transmit an electrical signal or current in your installation, you will need to use a rotary union equipped with a slip ring.

l How to calculate the dimensions of your rotary union?

There are many sizes of rotary unions available. Outlined below you will find the essential characteristics for calculating the size of your product.

The nominal diameter (DN) of your installation: this is the inside diameter of a connecting pipe.

The operating pressure of your installation: the rotary union is used in both vacuum and pressure systems. You will need to know the usual pressure of the media, generally between 0 and 1,380 bar (0 to 20,000 psi), and the maximum operating pressure. If the system operates at variable pressure, choose the maximum pressure as the operating pressure.

The operating temperature of your media as well as the ambiant temperature: you will need to determine the minimum and maximum temperature. They generally vary between -100°C et 200°C.

The necessary rotational speed and direction: the speed is generally from 0 to 3,600 rpm.

l What other characteristics are important to consider when choosing a rotary union?

The material of the union is important. You can choose one in steel, aluminum, brass, cast iron or bronze depending on the nature of the fluid to be conveyed. Then you will need to choose the type of connection: male or female, screw-in, flange, welded on or directly connected.
