Nitrogen is a colourless and odourless gas. The gas is chemically inert, non-combustible and oxygen suppressing. Nitrogen is present in air with 78.1% vol. Nitrogen serves in liquid, frozen form as freezing medium in the food industry and with the transport with refrigerated vehicles. Since nitrogen is an inert, odourless and tasteless gas, it is often used as atmosphere for the packaging of foodstuffs.

In the metal industry and mechanical engineering Nitrogen is used for the heat treatment of various types of metal and as a means of pressure in tanks or pipes. Also in chemical processes is nitrogen often used, for example in the synthesis of ammonia.

Cylinder identification

Colour  (according to NBN-EN 1089):

  • The ogive is painted in black RAL 9005
  • The cylindrical part is painted is painted in dark grey RAL 7031

Stop cock connection: G 5/8” - right / external (NBN226/DIN477)

Stop cock material: brass

Identification: ISO-sticker with ADR-data and H - and P-sentences according CLP


Piping systems are pressure and product-linked and the design must therefore be taken care of by competent people in observance with the current standards and legislation.

Each gas with its specific purity requires suitable material. For every application the appropriate material can be supplied such as: mufflers, flow meters, filters, valves, pressure gauges...
