Why Only Brass is used for LPG valves & fittings?
The perfect everyday examples are 14.2/ 19/47.5/425 kg cylinder gas valves, LPG LOT Valves, NRV, SRV, TRV, Flame arrestor, NRV, Regulators and filling guns.
Objective – All LPG valves and fittings are made from brass, have you ever thought why? Is it because of looks, finishing, low cost, easy for machining….???? or something else?
Only reason is “SAFETY” and lets see “How”….
What is Brass?
Brass is alloy made up of copper-zink.
Depending on the composition, the physical properties of the metal can vary. This includes strength, machinability, ductility, wear-resistance, hardness, color, anti-microbial, electrical conductivity, thermal conductivity and corrosion resistance.
Three qualities, the ability to form castings, great machinability and superb finishing make brass the best choice for manufacturing precision LPG valves and fittings.
What Makes Brass Good for LPG?
Sparks generated by “friction” can commonly occur when other metals impact on each other or on other materials such as steel or concrete. A mechanical or frictional spark is generated.
Unlike ferrous metals – metals containing Iron – which will generate sparks upon impact, brass does not spark on impact.
Brass is considered to be “non-sparking”.
Brass also tolerates low temperatures.
This is important because LPG vaporization can cause gas bottles and valves to become very cold.
Brass does not become brittle at low temperatures, unlike mild steel.
Brass is Recyclable – The recycling of brass is common around the world. Its high value provides great incentive to recycle.
Old gas valves and fittings are all recycled.
Making products from recycled brass is much more economical than using virgin brass.
Avoiding Sparks –
The fact that brass does not spark makes it ideal for the coupling of LPG valves and hoses.
During the connection of these common LPG fittings, it is not at all unusual for the fittings to bang into each other.
Being made from brass means that these impacts do not generate any sparks, preventing possible ignition, if flammable gas vapour were to be present.
In India the LPG industry is still in learning phase , we must understand and learn maximum precautions which can enhance safety at customers end to make LPG as popular Fuel.
Use of brass fittings is one of the many safety precautions taken with LPG gas.
If we have given choice to select Cost vs Safety , we at LIQUIGAS will select Safety first.
Nothing is more important than the safety of our customers, employees and Humanity.
