Equipment For Specialty Gases

Selecting the right equipment for handling a specialty gas product is critical to maintaining the overall purity of the gas stream at the point of use. Air Liquide Australia is able to provide the best equipment for a given application and/or advice on the features and benefits to look for in specialty gas equipment.

Materials in construction

It is important that all materials of construction in specialty gas (the “wetted surface” ) are compatible with the gas stream it is in contact with during use. Equipment such as regulators and flow indicators are made from stainless steel, brass, aluminum, glass, acrylic etc. Aluminium should not be used for oxygen or corrosive gases. For higher purity gases, stainless steel is generally recommended.

In basic terms, gases that are corrosive or containing corrosive species of gas eg. SO₂, H₂S, Cl etc, require the use of stainless steel equipment. Stainless steel is also the first choice when using the ultra pure grades of gases (>99.999%).
