Gas Manifold (Header)

Manifolds are used to connect two or more high pressure cylinders together for higher flow rates or for higher storage capacity. The manifolds could be arranged in a single row or in cases where space is a constraint, could be arranged facing each other. In most cases, to ensure zero downtime, at a time only cylinders in one of the rows are used. When gas in this row is depleted, the gas in the other row is used and cylinders in the earlier row are sent for refilling. The manifold system could be made of brass or SS. See below the CAD layout of a 6 x 6 manifold system.

The cylinders are connected using flexible hose to the manifold block valve mounted on the manifold block. The manifold blocks on one arm of the system are connected by a header pipe. The pressure on manifold arm is indicated by the pressure gauge. The manifold arm is connected to the pressure regulator through a non-return valve and a needle valve. The drawing on the right illustrates the connection details of the manifold valve and the pressure gauge on the manifold.
