Industrial Gas Filled Pipeline System

Industrial gases can be divided into industrial pure gas and industrial mixture of industrial pure gas and industrial or multi-gases of a single variety gas. In the National Standard ‘Bottle Compressed Gas Classification’ (GB16163-1996), it is classified according to the physical state and critical temperature in the gas cylinder according to the industrial pure gas, and groups in chemical properties, combustion, toxicity, and corrosive.

The first category is a permanent gas, and its critical temperature is <-10 ° C, when the filling, the storage and transportation in the allowable operating temperature, is divided into A, B group: Group A is non-toxic and non-toxic gases (including oxygen, nitrogen, argon, etc.), and B groups are flammable and non-toxic and flammable gas (including hydrogen, etc.).

The second class is a liquefied gas whose critical temperature is ≥ -10 ° C, including high pressure liquefied gas and low pressure liquefied gas. Among them, the high-pressure liquefied gas critical temperature is ≥ -10 ° C, and is ≤70 ° C, which is liquid during the filling, but during storage and use during the allowable operating temperature, as the temperature is raised to the critical temperature, that is, evaporative The gaseous, divided into three groups of A, B, and C: Group A is non-toxic and non-combustible toxic gases (including carbon dioxide), and B groups are flammable and non-toxic and self-contained toxic gases, and C is easy to decompose or polymerized. Low-pressure liquefied gas critical temperature> 70 ° C, during charge and in the allowable operating temperature

During the operation and use, it is also divided into three groups A, B, C: Group A is non-toxic and non-toxic and acidic corrosive gas (including chlorine); Group B is flammable and non-toxic and flammable and alkaline Corrosion gases (including ammonia); C group is a conventional or polymerizable combustible gas.

The third class is a gas dissolved in acetylene, dissolved in a gas cylinder under pressure, and only Group A: A group of convolutionally or polymeric combustible gases (including acetylene). This point

Class is the basis for mixed gas preparation.
