Why Brass Is Used For LPG Valves & Fittings?


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.

Conclusion –
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.

Why LPG is the Environmentally Friendly Option?

Posted by Prafulla Wankhede on Sunday 22 July 2018 at 00.40 am

There are seven main energy sources that are used in todays industrial/commercial society, they include electricity, natural gas, HSD, LDO, FO, Coal and LPG. While all of these energy sources are efficient, not all are environmentally friendly.

Considering how these energy sources have impacted our environment thus far, perhaps we should consider making greener options to ensure cleaner air.

Only three of them are environmentally friendly that are

1. Electricity 2. Natural Gas 3. LPG

Here is a comparison of these three energy sources and which ones are more environmentally friendly than others.

1. Electricity

Electricity isn’t the 100% eco-friendly energy source we all thought.

Electricity is a secondary energy source; this means that that it is generated by a primary energy source. This primary source could be the burning of coal, burning of fossil fuels, nuclear power and more. The issue with electricity is we are never certain how it is produced, which is why we can’t say it is 100% environmentally friendly. There are eco-friendlier ways of producing electricity, such as wind power and solar power, but they aren’t as commonly used as the sources that aren’t environmentally friendly.

2. Natural Gas – PNG/CNG/LNG

Natural gas is the cleanest fossil fuel, but not the cleanest energy source.

Natural gas a member of the fossil fuel family and is considered a greenhouse gas. However, compared to other fossil fuels, such as coal and oil, natural gas is the cleaner burning fuel. It releases more than half the emissions than other fuels when burned in an efficient power plant.

Natural gas does emit small amounts of sulfur and mercury into the air, as well as produces nitrogen oxides, which is a contributor to smog. These are all contributors to pollution, affecting our air quality.

3. LPG – Liquified Petroleum Gas

LPG is one of the cleanest & versatile fuel available. It isn’t toxic and emits lower greenhouse gas emissions than many other alternative options. However, even though it emits a small amount of greenhouse gas, LPG itself doesn’t act as a greenhouse gas due to how insignificant the emissions are. LPG is released as a gas, which means is doesn’t spill, pool or leave residue. In the unlikely event of a tank leak, LPG won’t harm the air, soil or water. Propane has also been approved as an alternative fuel by the Environmental Protection Agency (EPA).

Comparing these three energy sources is definitely an eye opener, especially when looking at electricity. We forget to consider how electricity is actually made and how its manufacturing process affects our environment. It’s important to consider all of these factors when making a decision as to which energy source to choose to power your home or cottage.

Conclusion –

If you are interested in a more environmentally friendly option, choose LPG.

What Is Effect Of Carbon Monoxide?Is It Poisoning?


What Is Efeect Of Carbon Monoxide?Is It Poisoning?
What Are The Symptoms?What Care We Should Take To Avoid Accidents?

You can’t see, taste or smell it but it can be deadly
Natural Draft Burners & non standard gas appliances (for example- Gas Geysers/ Gas Fryers ) can produce a highly poisonous gas called carbon monoxide (CO).
What is CO poisoning?
Ans : It can cause death as well as serious long term health problems such as brain damage.
CO is produced by the incomplete burning of liquefied petroleum gas (LPG) or Natural Gas ( NG ). This happens when a gas burners are not maintained, installed in closed room( bathroom/ basement) where no cross air ventilation , incorrectly fitted, badly repaired or poorly maintained.
It can also occur if flues gases, chimneys or vents are blocked or not present at all.
Oil and solid fuels such as coal, wood, petrol, Diesel, kerosene and oil can also produce carbon monoxide.
CO poisoning occurs when you breathe in the gas and it replaces oxygen in your bloodstream. Without oxygen, your body tissue and cells die. Even small amounts of the gas can cause CO poisoning, and long term effects can include paralysis and brain damage.

Remember the six main symptoms to look out for:

  • headaches
  • dizziness
  • nausea
  • breathlessness
  • collapse
  • loss of consciousness

Being aware of the symptoms could save your life, CO symptoms are similar to those of flu, food poisoning, viral infections and fatigue. That’s why it’s quite common for people to mistake this very dangerous poisoning for something else.

Other signs that could point to CO poisoning:

  • Your symptoms only occur when you are at factory ( Where LPG combustion is taking place) home and seem to disappear when you leave that place.
  • Others in your Friends, family , Co workers (including pets) are experiencing similar symptoms and they appear at a similar time.

What to do if you suspect CO poisoning

  • Get fresh air immediately. Open doors and windows, turn off gas burners & appliances and leave the premises.
  • See your doctor immediately or go to hospital – let them know that you suspect CO poisoning. They can do a blood or breath test to check.
  • If you think there is an immediate danger, call the Gas Emergency Helpline 1906.
  • Ask our Liquigas Engineers to inspect your gas burner/ boiler/ furnace/ oven and flues to see if there is a dangerous problem.

To find engineers who are qualified to investigate the presence of fumes, you can visit our Check our Website or business pages or do call us on 022 27700643. We have latest Gadgets including Gas leak detection system, Flue gas analysers, Portable blowers and measuring equipment’s.

The warning signs of a CO leak
Any of the following could be a sign of CO in your premises:

  • Flames of a lazy yellow or orange colour on your burner tip, rather than being a crisp blue;
  • Dark staining on/around combustion chamber, burner head and at mounting plate of burner;
  • Pilot lights that frequently blow out;
  • Increased condensation inside ventilation.

Faulty burner in your premises can lead to CO poisoning. Get your burner, boiler, and combustion system maintained and cleaned properly.

What can you do about it?

  • Our advice is clear: the first and best thing you can do to minimise the risk that your gas appliances produce CO is to ensure that they are safety checked annually by a suitably competent and qualified Liquigas engineer. You can find an engineer on www.liquigasindia.com
  • If you already have a AMC then an annual check may be included as part of it with flue gas analysis.

You don’t know what you are missing


Few days back I had the great pleasure of sitting in the Theatre of Dreams with my eldest daughter Eva. We were enjoying the FIFA U19 World Cup at D Y Patil Stadium, Navi Mumbai, India. Now, before anyone comments that “this isn’t Facebook” or “this isn’t Twitter” – I Know! This isn’t about the personal event.

There was a specific aspect which got me thinking, there were more than 20000 peoples sitting with us, world was watching a game, 12 minutes from the end and still 0-0, they left “to beat the rush”.
6 minutes later One player scored from corner and the place erupted, 6 minutes after that Opposite team Player scored and it went wild again – those two possible goals were outside, they had beaten the rush but they had no idea what they were missing.

That is the same as ignoring the innovations in our industry as you have “always done it this way”, you don’t know what you are missing.

Liquigas have been innovating for years, we have the best selling and performing telemetry ready, Liquitherm – we have a vaporizer that uses no electricity or fossil fuels just the warmth of the water. In the world, we have a SLOT ( LOT on SKID – Plug & Use), MOBI SLOT – READY To USE LPG ( First time in world), Duel Fuel/ Multi Fuel – highest efficiency burners using propane, Butane, Natural Gas, HSD, LDO, Furnace oil and off course LPG (BluFlam).
We have in-house Energy audit and implementing team which can save millions of dollars of our customers.

We have developed very Advance conversion technologies from other fuels to LPG in more than 300 different Industrial applications with end to end Solutions.

LPG Design


Everywhere in world shape of LPG cylinder is mostly cylindrical due to the fact that corners are
considered weak points for a holding such high pressure, ( 6 to 8
kg/cm2) .

Cylinder are designed and manufactured by having less weld joint
(again a weak point) and also the pressure inside will be
equally(almost) spread through out the cylinder having no single weak

Another best design can also be obtained by using *spheres* but
construction of sphere is very complicated and not cost effective at
all for such huge quantities. Hence such shape is accepted worldwide.

Why Pressure Gauges Don’t Work on LPG Cylinders ?


With compressed gas bottles, pressure drops as the compressed gas is
used, so a pressure gauge will indicate the remaining gas level.

However, LPG is not compressed gas, it is liquefied gas.
The vapour pressure varies with outside temperature but not with the
level of gas in the bottle.

As LPG is a liquefied gas, the vapour pressure inside the cylinder
will remain the same from full until the last of the liquid LPG is

So, if your are trying to determine the level of LPG remaining,
pressure gauges don’t work at all.

Yesterday I started my day
bit early as I was planning to go to Pune for my business tour.
Checked my emails, did regular activities and went to gym.

While coming back I was preparing myself for hectic schedule, thinking
of meetings, presentations, production plans and service calls of the
day. Suddenly got distracted by loud horn blown by my driver and car
stopped at my residential complex gate.

He was trying to call watchmen/ Security guard to open it. I stopped
my driver and asked him to wait and not to blow horn.

Nobody came on gate to open it, I came out of my car and opened gate ,
asked driver to park the car and personally started searching security
guard. I found him immediately, he was just near gate and was cleaning
one old school bag thrown by some resident and very busy in it.

I went near to him, put my hand on his shoulder and asked “क्या कर रहे हो भाई?”

He was shocked and feared by looking at me, he understood his mistake
then started saying sorry to me for not opening door. I said ok to him
but I was more curious to know why he couldn’t listen horn and why so
busy with that school bag?

I asked him what exactly you are doing with this bag? He replied – ”
साहब, सोमवार से स्कुल शुरु हो रहे बच्चोंके , स्कुल बॅग नहीं था घरपर,
आज अचानक यहां किसीका पुराना पडा दिखाईं दिया , अच्छा लगा तो उसे साफ कर
रहा था।बच्चा बहोत खुश हो जायेगा , यह सोच रहा था तभी आप आ गए। ”

I felt ashamed and started thinking our own lifestyles still I asked
him did he purchased other things like notebooks, pen-pencil etc. He
said NO because contractor has not yet paid him salary.

I easily understood from his voice and eyes that he was feeling guilty
and was in huge pressure, that might be reason he could not even
listened loud horn of my car as his heart was beating more loudly than
anything else for his kid.

I gave him Rs.2000 at that time and I asked him to purchase things and
blessed for his kid. I left from there came home and got fresh up and
rushed to Pune for my scheduled work.

Whole day I was very busy and very hectic. I came very late to mumbai
around 4 am, was completely forgot watchmen’s episode.

Today around 8.30am someone ranged my door bell. I was very tired
still woke up and opened door with tired face. Surprised to see same
watchmen with one bag and Bill.

He saw me and understood I didn’t liked his arrival, after apologizing
he gave me bill and returned Rs. 600. Showed books and all other
accessories and said – “सर, चौदासौ रुपये खर्च हुए बाकी 600 रूपये वापस
देने आया हुॅं।”

I was thrilled with his attitudes and felt happy from bottom of my heart.

I saw satisfaction, happiness, and purity on his face but tears came
from my eyes looking at his honesty and transparency.

I am still feeling I didn’t helped him, fact is he only help me by
teaching such a good lesson of honesty.

Hats to him and may God bless all of us with same honesty, Pure mind
and helping hands.

How to check the level of gas in your LPG cylinder


You can check the level of gas in your LPG cylinder by carefully
pouring *warm water* down the side of the cylinder. Give it a minute
and then run your hand down the cylinder. It will feel cool to the
touch at the level of the gas.

Be super careful with the warm water, It must be warm and *NOT HOT.*
