The pressure in a gas container, cylinder or bundle is controlled by a gas manifold. Typically, a manifold consists of a supply unit and a backup unit.
Benefits of a gas manifold:
- streamlines the handling of gas cylinders
- reduces transport costs
- reduces cylinder lease costs
- reduces need for space
- makes gas cylinders easier to handle in the event of an emergency, such as fire.
Gas manifolds are either manual or fully/semi-automated, with an alarm function to give a warning when gas is running out also available.
Gas pipes are always made from material selected on the basis of the application and features of the gas in question.
Pipe system classifications are based on the following factors:
- hazardousness of the chemical
- form of the chemical (gas/liquid)
- nominal pipe size (DN)
- maximum working pressure (PS)
From gas pipe networks, the gas is accessed at the end-use location via an outlet connection where the gas pressure and flow rate are controlled. The outlet units consist of a shutoff valve, pressure regulator, a possible flow meter and a hose connector.
