Gas mixer helps clean steel pipework
A gas mixing system used with an integrated O2 analyser and receiver, can be used by steelworks, when cleaning pipework to determine the optimal oxygen percentage for differing cleaning processes.
The MG500-2ME gas mixing system from Witt Gas Techniques, the Warrington, UK-based gas safety, control, mixing and analysis equipment supplier, used with an integrated O2 analyser and receiver, can be used by steelworks, when cleaning pipework to determine the optimal oxygen percentage for the differing cleaning processes that are used This mixer has a capacity range from 0 - approximately 270Nm3/h and is easy to operate with a control knob and percentage scale providing infinitely variable mixture settings

System delivers gases, air, power from one point
From one central point, a modular energy compact system provides services such as Acetylene, Oxygen, CO2, Argon, shielding gas as well as compressed and fresh air, vacuum and electricity.
It has a +/-1% setting accuracy.
During steel production, argon and nitrogen are added to the liquid steel to achieve the best possible mix.
An after effect of this process is that the pipework often clogs up and the gas supply is cut off, therefore regular cleaning becomes essential.
Compressed air is mainly used to clean the pipework of the converters in the steel production process.
The results of this cleaning can be improved by using higher proportions of oxygen in the compressed air.
However a note of caution is added, too much oxygen and the mix could detonate, too low a percentage not all the contaminations can be burnt away.
Around 30% of oxygen in the nitrogen produces the best results.
The MG500-2ME gas mixer ensures that the correct control and volume of oxygen is used.
An EEx version for flammable gases using a separate control cabinet is available as an option, monitoring of the gas supply is an option using pressure switches; if the inlet pressure becomes too low, an optical or audible alarm is triggered and the machinery being monitored is shut down reducing risk of any problems occurring and also available is an integrated gas analysis for monitoring, control and documenting the gas mixture.
