Safe Handling of Acetylene Cylinders To Avoid Potential Hazards

Acetylene is inherently a safe gas and is an invaluable commodity for the industry. Being a highly flexible gas, acetylene is used in many industrial processes. It is known to an irreplaceable for oxyfuel gas welding and cutting. It features high versatility and functionality with also being hazardous if not handled with care. However, the acetylene cylinders have a different design from most other gas cylinders and the gas reacts differently when exposed to fire.

Safeguarded by acetylene cylinder valves, the acetylene cylinders consist of a steel shell comprising a porous mass which in combination with liquid acetone dissolves the gas. Decomposition of acetylene is triggered by heat, leaving the cylinder in an unstable, hazardous condition and can also lead to explosion.

Due to the special potential for a delayed action rupture with acetylene cylinders, observing certain safety measures to minimize the risk and level of destruction.

Tips to handle acetylene gas cylinders:

• The alarm should be sounded and area evacuated in case of any event of an incident.
• Train the user appropriately before letting him use Oxyfuel gas equipment.
• Fit non-return acetylene valves on the torch
• Check for any leaks prior to lighting up
• Prefer to ignite the fuel gas equipment before introducing the oxygen stream with the nozzle pointing upwards
• During transport, ensure that the vehicle is properly ventilated and there are appropriate restraints to save the gas filled cylinders from exploding
• After being transported, the acetylene cylinders must be left to settle in an upright position so that the liquid acetone returns to its normal position in the porous mass
• Always use a flashback arrestor while using acetylene cylinders
• Never open the acetylene cylinder valves more than one and a half turns as it can be closed easily in case of an emergency

Selecting The Right CNG Valves

Gases are classified as inert, oxidizer or flammable gases. The property of an oxidizer gas is that it is not flammable but contributes to the combustion reaction. Inert gases do not react with other material nor do they aid in combustion. Flammable gases burn or explode when reaction with oxygen.

CNG or compressed natural gas, methane or ethane is a hydrocarbon based flammable gas. CNG like most commodities can be easily stored for a long period of time. It is normally stored in underground storage facilities and transported in the tank.  CNG is required to be transported to diverse locations for various uses. 

Compressed gas valves are used in pipelines to allow or stop the flow of the gas. The compressed gas valve is used to restrict the flow if pipe repair and maintenance is to be carried out. 

How to select the right valve CNG valve

Compressed Natural Gas (CNG) Valves

CNG valves are specifically designed for use with this flammable gas. When you are searching for a valve look for the following key features:

• Choose a compressed gas valve that is manufactured by an automated assembly process
• It is 100% tested for helium leak
• Forged brass, heavy duty body is necessary for durability and safe working under high pressure
• The metal to metal seat below the bonnet provides excellent flow characteristics

Types of CNG valves

As per the design specifications, there are different types of compressed natural gas valves that are widely used in CNG applications. The two types of valves are:

• For working pressure up to 3000 PSI
• For working pressure above 3001PSI to 6000 PSI

The body and bonnet of high quality compressed gas valve are usually made from brass, some models may be chrome plated.  The handwheel is either made from aluminum or steel, while the lower plug can be made from brass or nylon. The stem should be made of brass and the backup O ring of PTFE. These features are the basic in good quality cng valves that offer safety and reliability.

Applications of CNG valves

Chrome plated CNG valves are used in service of methyl fluoride, ethylene, natural gas. The valves are designed to function at different temperatures and pressures for all the gas services. Depending on the utility and functionality of the valve, one can select the inlet and outlet size. 

With leading portals like JTC valve sales, there is no need to go shopping to stores when you can find all that you require right here. With the widest range of gas regulator and valves for the cryogenic and gas industry, easily find the valve you are searching for that too at the most competitive price.

Know All About Valves To Get The Most From Your Valves

Industrial valve manufacturers conduct continues research to develop innovative products that are of high quality, durable and can be manufactured at lower costs. As the quality and price of the valve changes, the complete cylinder industry is affected.

Industrial valves include Chlorine valves, medical cylinder valves and welding cylinder valves. The valves are usually operated by hand though innovation and technology has led to valves being of the automatic type that are operated by computerized control systems.

A few commonly asked questions have been answered here for your convenience. We are attempting to give you information on valves. In case you do have some queries, do feel free to write to us and our experts will get back to you.

Q) which is the best valve for oxygen service?

The slow opening needle valve is best suited for O2 service. Ball valves should not be used as they may pose a potential hazard by creating circumstances that are right for ignition.

Q) What kind of valve can be used for vacuum applications?

Diaphragm valves are best suited for vacuum applications due to their diaphragm and metal seal design.

Q) Should ball valves be used for throttling functions?

No. Absolutely not, as throttling causes premature wear of the side discs and packing.

Q) Is there a difference between Cv and orifice size?

Cv stands for U.S gallons flow of water per minute at 21 Deg C with a pressure drop of 1 psi across the valve.  Orifice size is the actual measurement of the size of the flow path.

Q) JTC valve sales stocks valves manufactured by?

JTC valves sales stocks all American made valves that are manufactured by Rego and Sherwood who are leading valve manufacturers.

Q) how to handle cylinders and containers when being moved?

Damage to valve or ruptured cylinder is hazardous. The handler must:

• Wear gloves to protect against pinch injuries
• Safety glasses must be worn to protect the eyes from injuries related to pressure release
• Metatarsal support safety shoes are a must to protect against foot injuries

Q) what are the safe practices for moving cylinders?

• Shut the outlet valve completely
• Valve protection caps should be secured tightly in place
• Use carts or hand trucks to move the cylinders
• Do not allow the cylinders to bang or strike violently against each other
• Do not lift cylinders by the cap or lifting magnet
• Store the cylinders as per the NFPA codes

Q) How to test the cylinder valve for leaks?

The leak test method is used to check cylinder valves for leaks.
