Hydrogen Cylinder
Hydrogen cylinderA hydrogen cylinder contains the lightest and most energy-rich gas in the world, which plays a strategic role in modern industries, reduction processes and laboratory systems. With the molecular formula H2, because of its special thermal behavior and high flammability, this gas must be stored in tanks built to the highest metallurgical standards. Bonyan Gas supplies this product in grades from industrial to ultra-high-purity laboratory (UHP) and in a variety of volumes to steelmaking plants, chemical industries and research centers across Iran.

Because of its special properties, hydrogen tends to penetrate the crystal lattice of some metals and over time can cause cracking or sudden failure of the tank; materials engineers call this “hydrogen embrittlement”. For this reason, the body alloy and periodic inspection history are especially important for this product.
Using seamless hardened steel in the production of these cylinders is also an engineered, cost-effective choice that ensures long life and durability in continuous industrial use.
This care extends to the outlet connections: the cap and valve thread of these products are left-hand, so they are distinct from right-hand threads and wrong connections are impossible.
Bonyan Gas, under the direct supervision of its engineering team, guarantees the soundness and technical compliance of these valves before supply.
Ordering, refilling and exchange
Hydrogen cylinder supply is flexible to suit your workshop or laboratory. If you already have a used cylinder, exchanging the empty tank for a full one or refilling it is a faster and more economical way to move your project forward. For setting up new production lines or a first order, brand-new sealed cylinders are also available.
The different gas grades and purchase options are described on the hydrogen gas page.
Safe storage
Keeping pressurized cylinders in the workplace requires strict adherence to the safety chain; hydrogen cylinders must always be stored fully upright, secured with chains and fitted with a valve protection cap. Given the highly permeating nature of this gas, never roll or drag cylinders along the ground, because the slightest impact to the valve core can cause a sudden gas release and serious hazards. In addition, visual inspection of the connections before each start-up is mandatory, and periodic tests such as the hydrostatic test on schedule ensure the structural integrity of the tank.
Cylinders undergo a hydrostatic pressure test (250 bar) and safety inspection according to the relevant manufacturing standard to ensure they are sound and fit for use.
The service life of a cylinder depends on build quality, storage conditions and the results of periodic inspections. If it passes the technical tests, a cylinder can be used for many years.
It depends on capacity, body material, manufacturing standard and whether the equipment is new or exchanged. Contact our experts for an exact figure.
Because hydrogen can penetrate the structure of some metals and make the body brittle, the cylinder material for this gas is directly linked to safety, not just price. Steel with regular periodic inspection is the reliable and more economical choice for continuous industrial use; focusing on one material also lets us track the build quality and inspection history of each cylinder more closely.
