SCHWERLL offers users welded, single‑layer, fixed‑type pressure vessel cylinders with individual capacities of up to 5,000 L. Standard designs are available at two pressure ratings: 220 bar and 350 bar. These vessels are used in stationary accumulator systems, particularly for ultra‑large accumulators, and are commonly employed in applications such as buffering and balancing systems on offshore platforms, as well as in large extrusion and free‑forging equipment.
