Helium cylinders: specifications

Helium is a representative of the group of inert gases that has unique chemical and physical properties. Under normal environmental conditions, it has a gaseous state and does not form any chemical compounds. Light gas, odorless and color, absolutely non-toxic and is supplied by our company in special helium cylinders , which guarantees a high level of safety. Therefore, the use of gas is widespread in industry, medicine and everyday life.

Helium Applications

In today’s world, most people have heard about helium applications:

• metallurgical industry – for the production of metals and alloys;
• medicine – in combination with oxygen to alleviate the condition of patients with pulmonary diseases;
• nuclear power – as a coolant for reactors;
• food industry – as packaging gas;
• entertainment sphere – balloons rushing up, creating a festive atmosphere.

Helium is the most common gas in the Universe after hydrogen; therefore, not all areas where it is actively used are listed.

Helium Storage

Tanks for storage and transportation of compressed gas are cylinders, the parameters of which are prescribed in GOST-949-73. They are made of alloyed or carbon steel by cold rolling with the exception of welds. To withstand stress, the tank is made in a cylindrical shape with a rounded bottom, the working pressure should be up to 200 kgf / cm2.

Helium cylinders are usually coated with brown enamel, the word “Helium” is written on top of them with white paint. The most common are containers with a volume of 10 l, 40 l and 50 l. Fully filled with helium compressed to 150 atmospheres cylinders correspond to the indicators given in table 1.

Table 1 – Characteristics of helium cylinders

 
In the upper part of the cylinder there is a valve under which a stamp is stamped with the necessary information:

• serial number and date of first certification;
• maximum operating pressure and pressure limit data;
• data from previous audits and tests.

Next to the date is the seal of the organization that conducted the audit. Validity period of certification is five years.

You can order certification of cylinders for helium and other gas mixtures at Helium24. We guarantee that all work will be carried out in accordance with the regulations and issue all the necessary documents. Pleasantly surprise the client and the pricing policy of the company.

Terms and conditions of transportation of cylinders

Helium belongs to the category of non-flammable gases and belongs to class 2A. Therefore, according to the documents regulating the allowable volume of transportation of such goods, a person in a private car can carry a total of 1000 liters. In addition, it is important to follow the rules for moving containers, to avoid drops and bumps, which can lead to damage to the valve or body and gas leakage.

For short distances, the cylinder alone needs to be moved by rolling in a vertical, slightly tilted position. For longer distances, it is recommended to carry the container together. The best option is to order a service for transportation of helium cylinders at Helium24. In this case, all work on the delivery and installation of containers is transferred to the shoulders of professionals, which will save time and not expose your company to unnecessary danger.

The heating of the cylinder leads to an increase in the gas pressure on the walls of the vessel, therefore it is unacceptable to heat it above the critical mark of 50 ° C. To avoid the explosion of the cylinder, it is necessary to keep it away from direct sunlight and heating appliances. Subject to storage and operating conditions in accordance with the regulations, helium is stored in cylinders for the period established by the certificate.

The Helium24 company is selling liquid and gaseous helium ready to offer its services and arrange delivery to any corner of the country and neighboring countries. You can place an order for the desired product or service on the site. Cooperating with us, the client receives quality services at affordable prices.
