Use our online accumulator volume sizing calculator to determine optimal capacity.
Open Volume Calculator →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.
Contact Schwerll engineering sales directly for custom volume sizing, pressure ratings (up to 207 MPa), and volume pricing.
SCHWERLL can provide users with single-layer welded, fixed-pressure vessel gas tanks for ultra-large-capacity high-pressure piston accumulator systems:
This product is designed for applications involving alternating operating pressures and is suitable for service conditions where δP exceeds 5%. The advantages of SCHWERLL’s single‑layer welded pressure vessel gas cylinders are as follows:
1. Unlike multi-layer composite high-capacity pressure vessel cylinders, SCHWERLL supplies single-layer welded pressure vessel cylinders. The monolithic structure ensures that stresses are not amplified and transmitted to the outer layers, resulting in a simple load-bearing configuration that is well-suited for cyclic fatigue service conditions.
2. SCHWERLL supplies single-layer welded pressure vessels with a nominal volume ranging from 1,000 L to 5,000 L; standard products are designed for pressures up to 350 bar, while custom‑made units can be engineered for design pressures of 500 bar or higher.
3. SCHWERLL supplies single-layer welded pressure vessels and gas cylinders that, thanks to a specialized welding process, fully meet the stringent internal‑surface cleanliness requirements of their intended applications, ensuring no yellow rust or other contaminants arise during service.
4. SCHWERLL supplies single-layer welded pressure vessels and gas cylinders, with product manufacturing strictly compliant with pressure vessel codes, ensuring product quality and safety. The products are equipped with bottom drain valves that enable on‑line maintenance.
