Filling Manifold

This consists of a battery of 60 filling connections to connect to the gas cylinders. Non- return valves are provided in various sections of the pipeline to the filling manifold. These non- return valves are extremely important for the safe operation of the plant and should be periodically cleaned to remove rust and scales. The cylinder filling pig tails (flexible hose pipes) should also be periodically cleaned to ensure that they do not burst during filling operation.

The cylinder filling manifolds are protected with flame arresters placed before and after each shut-off valve. The cylinder filling leads are also protected with stem reverse flow check valves which allow cylinders with uneven pressures to be connected to the cylinder lead. The manifolds are equipped with water sprays to keep the cylinders cool while filling.
