Hydrogen High Pressure Vessel and Storage Tank

The Hydrogen High Pressure Vessel and Storage Tank (LEHHPVST) is an industrial pressure vessel for storing hydrogen at high pressure. Nominal volumes run from 100 L to 200 m3, with design pressure from -1 to 200 bar and design temperature from -40 to 350 °C. Vessels are built vertical or horizontal and stand on lugs or a floor stand with legs.

How it works

Wall thickness follows working pressure: the higher the pressure, the thicker the cylinder wall. Base thickness runs from 6 to 160 mm. Once the wall exceeds 16 mm, clad plate can be considered, with the base material carrying the pressure load and a clad layer of 3 to 10 mm resisting corrosion. Listed materials are carbon steel, SS304, SS316, titanium, nickel, Hastelloy B/C, Monel, zirconium, Inconel and tantalum; lined construction is also listed.

Heads are semi-elliptical, dished, hemispherical or flat. A dimpled, half-pipe or standard jacket can be fitted, heated by oil electric heating, oil heating or steam. The table lists a maximum length of 16 m, diameter of 6 m and weight of 200 tons. A vessel over 6,000 mm in diameter is fabricated on site. One over 200 tons unit weight or 40 m total length ships in segments for field welding.

What is included

• Pressure vessel shell with the selected head type, on lugs or floor stand legs

Technical Specifications

Note: If the diameter exceeds 6,000mm, it need to be fabricated on the site.

If the unit weight exceeds 200tons or the total length exceeds40m, segmented transport and field welding will be required.
