High‑parameter seamless, formed, stationary pressure vessel cylinders supplied by SCHWERLL:
Unlike cylinder‑type gas cylinders used in applications for transporting and securely storing gases, the high‑parameter stationary pressure vessel cylinders supplied by SCHWERLL belong to the pressure vessel product family. They are designed for use as backup gas cylinders in piston accumulators and are suitable for equipment subjected to cyclic operating pressures. The key advantages of these products are as follows:
1. The product’s capacity range spans from 500 L to 2,000 L per unit, making it suitable for high-pressure applications. Available pressure ratings include the 220 bar, 350 bar, and 450 bar series.
2. SCHWERLL supplies high‑parameter, seamless, fixed‑type pressure vessels manufactured using hot spin‑forming for the closure, with an inner wall finished by a coarse‑grit shot blasting process, resulting in a smooth, clean surface that effectively enhances the metal’s fatigue resistance.
3. The product’s base is equipped with a SCHWERLL–specifically designed high-pressure drain valve assembly, which, when operated in accordance with established procedures, enables online drain‑and‑maintenance operations.
