Gaseous nitrogen (N2)

Gaseous nitrogen (N2)

GASEOUS NITROGEN (N2)

GOST 9293-74 (HS code 280 430 0000)

Gaseous nitrogen is meant for creation of inert atmosphere at manufacturing of easy oxidize products under high-temperature process of metalworking operation, noninteracting with nitrogen for preservation of self-contained metallic tanks and pipelines. Gaseous nitrogen is an inert gas without a color and smell.

Safety Requirements: the nitrogen is non-toxic, inexplosive. Accumulation of gaseous nitrogen causes an effect of oxygen insufficiency and asphyxia.

Packaging: in barrels and truck tankers.

Transportation: gaseous nitrogen is transported in special barrels.
