Product Description

Product Description

99.999% High purity Hydrogen H2 Gas

Process:

Hydrogen is most frequently produced for on-site usage by steam reforming of natural gas. Such plants may also be used as sources of hydrogen for the merchant market. Other sources are electrolysis plants, where hydrogen is a by-product of chlorine production, and various waste gas recovery plants, such as at oil refineries or steel plants (coke oven gas). Hydrogen is also produced by the electrolysis of water.

Specification:

Cylinder: 40L                                                  Valve: G5/8  ;    QF-30A/CGA350               

Cylinder bundle: 40L*16                                 Valve: G5/8  ;QF-30A/CGA350                

Application:  

High purity hydrogen is used

1. in the electronics industry as a reducing agent and as a carrier gas

2. as a carrier gas in gas chromatography

3. in the metals industries because of its ability to reduce metal oxides and prevent oxidation of metals during heat treatment. It may be used either pure, as is often the case when heat treating stainless steel, or in a mixture with inert gases, argon or nitrogen. It is used in the production of carbon steels, special metals and semiconductors
