Cylinders For Compressed Gases

High pressure Gas cylinders are made from steel and aluminium alloys and are fitted with valves. The gas contents are identified by a system of colour coding, stenciling and adhesive labels. In every cylinder following information is marked by permanent stampings:-

• Filling Pressure
• Serial Number
• Test Pressure
• Name of the manufacturer & country of origin
• Date of previous pressure testing and/or inspection with the stamps of the concerned authorities
• Stamp of official authority

These marks should not be removed or defaced from the cylinder as otherwise cylinders would not be filled.

Cylinder Storing

The storage of cylinders is governed by the National Fire Protection Association (NFPA). Local codes also apply. The codes governing the storage should be maintained at all locations. Compressed gases should follow specific storage guidelines.

Cylinder Handling

Cylinders must be handled most carefully. Mishandling may cause a damaged valve or ruptured cylinder could expose personnel to the hazards associated with these gases. The personnel responsible for the receiving of cylinders should inspect cylinders externally before moving them to the point of use or to the storage area. Personnel should be equipped with the necessary safety equipments as required for various types of gases.

Valve Operation

By maintaining a few simple rules at the time of opening and closing of valves can prevent damage to valves and add years of service life to the valves.
