CNG/Biogas and Hydrogen transportation containers

Type 4 ultra lightweight cylinders

Type IV cylinders have plastic lining, stainless steel end fittings and composite construction of high-strength fiberglass and epoxy resin.

The use of such materials eliminates problems with corrosion and also guarantees the absence of galvanic corrosion. The cylinders are tested for a safety factor from 3.2 to 3.4. Cylinder designed for 250 bar, has a burst pressure of 840 bar or higher.

The cylinders are approved for EN 12245 and far exceed the requirements of this standard. This is especially important when testing for defects or impact and fire damage. For operating pressures of 200 and 250 bar, cylinders of various volumes are available. Each cylinder can be up to 2400 liters and is intended for both transport and storage of CNG or BIOGAS. HYDROGEN storage cylinders are also available.

Containers can be filled up to 15 000 times, which gives them a long life.

Safety is very important when transporting and storing flammable gases under high pressure. AT UAC products this is reflected in the parameters of the cylinder, and in the design of the container.

– Containers have steel or aluminum side walls to protect the cylinders from external impact.

– Designed, calculated and tested in accordance with the requirements of ADR (standards transportation of dangerous goods)

– All type approval tests have been carried out jointly with DNV-GL and

approved in accordance with TPED / ADR .The cylinders are 8 times higher than the requirements for fire tests without any devices
overpressure or heat release. Therefore, the client can decide whether to equip containers with these devices or not.

Since the lining is plastic, and the end elements are made of stainless steel, type 4 cylinders are very resistant to corrosion. This is important even with small amounts. CO2 / water and / or H2S. Composite materials utilized in design of UAC pressure vessels offer non-corrosive properties, wide temperature tolerances, high-strength fatigue durability, enhanced safety and a long design life in harsh and hazardous environments, and offer up to 70% weight reduction, compared to steel cylinders. Composite materials are highly flexible and scalable to accommodate larger containment and transportation gas volumes.

Type 4 cylinders are suitable for stationary storage solutions designed for pressures up to 250 bar, with different configurations depending on the required volume.
