Why aluminum cylinders are the preferred choice today

Most people believe that thirteen is an unlucky number. Read this and you will probably change your mind that few 13 are awesome too. Aluminum is a metal that is widely used in almost applications from food preservation to airplanes. It is one of the most ductile, durable, flexible and recyclable metal.  Its atomic number is 13. 

 In 1886 two engineers, one from USA and other from France discovered aluminum. Aluminum makes up around 8% of the Earth’s crust and is found in the form of bauxite ore from which aluminum is isolated.  Did you know that aluminum gas cylinders are in existence since 1941? They were invented in France, later seamless cylinders were manufactured by the cold-extrusion method in the mid 1950s in the UK.  During the ancient times, Greeks and Romans used aluminum compounds for medical purposes, to dye clothes and as an astringent. In 1850s, aluminum was priced at $ 1200 per kg whereas gold was priced at $ 664 per kg.

Aluminum cylinders are used to transport a variety of gas mixtures. The aluminum cylinders are pressurized gas cylinders that operate safely in the most hazardous environment. Aluminum is the choice for tanks, scuba cylinders, oxygen medical cylinders, CO2 and helium. They are naturally resistant to oxidization. 

Carbon dioxide aluminum cylinders store working gas at very high pressures which is used to drive pneumatic tools. The sizes available are tailored for mobile or static applications.

Aluminum cylinders have a wide range of applications in domestic as well as industrial purposes. There are a few characteristics that you must look for in an aluminum cylinder whether you want to use it for beverages or other gases or helium.

  • Cylinders must be durable, tear and crack resistant and fracture toughened
  • If using for wet gases then the aluminum cylinder should be corrosion resistant from the inside and the outside
  • The cylinders should perform well at low temperatures
  • The thick walls render the cylinders resistant to damage
  • If the external surface is brushed, it provide a low maintenance finish
  • The aluminum cylinders must meet worldwide regulatory standards
  • The cylinders must come with a training manual and safety guide

Latex And Mylar Balloon Inflators A Popular Device



Balloon inflators, mylar, latex…are you wondering what is the big deal when you simply have to inflate a balloon? Well, mylar is a heat resistant plastic film which is a form of polyester resin also known as BoPET (biaxially oriented polyethylene terephthalate) while latex is foam rubber. Both are widely used to make balloons. 

Balloons make you think of parties. Halloween is just round the corner so it is time to plan for the party. Themed balloons are available in different prints which you can customize too.  All you need is a balloon inflator to get the party going.  Gone are the days when you had to blow your lungs out to inflate the balloons and be dead tired even before the party began. Whether you are using mylar balloons or latex balloons find the right balloon inflator and inflate to your heart’s content! 

Ways to blow a balloon

  • Blow air into the balloon by mouth – tire your mouth and lungs
  • Use the chemical reaction between baking soda and vinegar which releases carbon dioxide and inflate the balloon – one balloon per reaction
  • Use balloon inflators – simplify the balloon blowing ritual
How to inflate a mylar or latex balloon with helium or carbon-di-oxide

  • Purchase the balloon inflator from JCT valves Sales
  • Attached it to the helium or gas cylinder
  • Stick the opening of the balloon to the nozzle of the inflator
  • Release the valve by pressing on the nozzle for the gas in the cylinder to flow into the balloons
  • Release the pressure from the nozzle to close the  inflator valve when enough gas is filled in the balloon
  • Mylar balloons are self sealing, they should not be tied with a string as it may cause leakage
  • Helium balloons will float around so use the hole below to secure with a ribbon or a tie
  • Latex balloons should be either knotted or tied with a ribbon/string after they are inflated
Get the best mylar/latex balloon inflators from JTC valves sales, the leading suppliers for balloon inflators.  

Key features of balloon inflators available at JTC Valve sales

  • The balloon inflators have a forged brass body
  • The hand tight connections are made of plastic or brass
  • The rubber tilt valves, bronze inlet filters of balloon inflators are replaceable
  • The push down mylar fill nozzle is made from brass
  • The balloon inflators come with auto shut features
  • Repair kits, parts and accessories are easily available at jtcvalvessales.com
Latex balloon fillers and mylar balloon inflators available at JTC Valves sales are very economically priced. Each inflator is tested for leaks before shipping. The different models available are hand tight connected, content gauges, string cutters. The latex balloon inflators can be customized for filling multiple balloons as well which saves your time. You have the option to choose independent latex inflator, mylar inflator or the inflator designed to fill both latex and mylar balloons in one unit. Using a rubber tip to inflate mylar balloons will cause damage resulting in the balloon losing helium quickly. The rubber tip valve may tear the balloon, pop the seam or create small pin holes. Look for an inflator with auto stop to avoid overfilling the balloon. Latex balloons expand more than mylar balloons.

Choose The Best Compressed Gas Cylinder And Valves



Compressed Gas Cylinders & Valves

Compressed gas means any mixture or any material in gaseous form whose absolute pressure exceeds 275.8 kPa at 21 Degree C or an absolute pressure exceeding 717 kPa at 54 deg C or both, or a liquid who absolute vapor pressure exceeds 275.8 kPa at 37.8 deg C.

Compressed gases are toxic, inert, corrosive, flammable or oxidizing. If an inert gas leaks, it displaces air and creates an oxygen deficit environment. Toxic gases make the atmosphere poisonous. Flammable or reactive gases cause explosive fire. The high pressure of the gas or build up of further high pressure can break the cylinder or become a missile if the cylinder valve breaks. Identifying and using good quality cylinders and valves is necessary for proper storage or transport of the compressed gas and to prevent accidents

Hazardous properties of industrial gases
  • High pressure – most of cylinder gases are under high pressure between 2000 psi to 3000 psi. Compressed cylinder gases are available up to a pressure rating of 7500 psi
  • Extremely cold – gases like helium, hydrogen, carbon dioxide, nitrogen or oxygen are stored in cryogenic liquid form. The temperature of the liquid and vapor ranges from -109 deg F to -452 deg F. A build-up of high pressure may arise from the trapped evaporating liquid. A good quality valve and cylinder that sustains higher pressure can reduce the chances of an accident
  • Inert gases like argon, CO2, helium and nitrogen may cause asphyxia. Proper ventilation at the place of storage along with 19.5% of oxygen ensures safe storage
  • Oxidizers – oxygen and nitrogen oxide are the two industrial gases that do not burn, but do burn with explosive violence. Keep all organic material away from Oxygen, do not lubricate the valves and prevent spillage of liquid oxygen on surfaces
  • Flammable – gases like propane, hydrogen, acetylene are highly flammable gases. Cylinders for storage of these gases should be carefully selected with valves that do not react with these heavy gases.
How to Store Compressed gas cylinder
  • Compressed gas cylinders should be stored where the ambient temperature does not exceed 52 deg C. If the ambient temperature does exceed this temperature, there is a great probability of gas release in spite of the over-pressure protection device which is usually a valve
  • The indoor areas used for storing compressed gas cylinders must be dry and well ventilated to prevent the buildup of gas vapors which may cause leakage of the gas and corrosion of the cylinder too
  • For highly inflammable gases like oxygen, oils or grease should not be used for lubricating the valves as it could easily ignite and cause a major accident due to connection failure resulting in more release of oxygen
  • If the compressed gas cylinders are stored outdoors, they should be placed on a raised, non-combustible platform and protected from the weather, dampness which may corrode the cylinder and cylinder valves
  • Keep the valve closed when the cylinder is not in use
  • Always store the cylinder in an upright position
  • Use regulators, valves and other fitting that are designed for that gas, do not interchange
How to choose the right cylinder and valves for compressed gases

Depending on the type of gas that is to be stored, the choice of material for cylinder is to be made. Aluminum has replaced all other material for making cylinders. Aluminum cylinders have a special advantage of being lighter in weight, more durable, it is lower in cost and is relatively easy to repair. Aluminum cylinders are widely used for welding, beverages, oxygen therapy, industrial or specialty gas applications. A wide range of high or low pressure and various sizes of aluminum compressed gas cylinders for various purposes.
