Use our online accumulator volume sizing calculator to determine optimal capacity.
Open Volume Calculator →Piston accumulator system integration—featuring volumetric matching and hardware configuration tailored to user‑specific operating conditions in accordance with thermodynamic equations—is a standard offering from SCHWERLL. Compared with hydraulic systems or piston accumulator systems manufactured in‑house by OEMs, SCHWERLL piston accumulators boast product and system certification standards, modular delivery of the complete system, a high‑cleanliness delivery condition, and enhanced safety in the overall system design and construction details.
Contact Schwerll engineering sales directly for custom volume sizing, pressure ratings (up to 207 MPa), and volume pricing.
SCHWERLL The construction of piston-type accumulator systems shall comply with the applicable national and regional codes and standards of the installation site.
SCHWERLL Strictly in accordance with TSG21-2016/GB150/GBT20663-2017、 ASME Standards and the European Union EN14359 In accordance with the requirements, the safety accessories that must be installed on the accumulator system include:
The specialized equipment used to construct piston-type accumulator systems must be fully compliant with national regulations. The relevant regulations governing accumulators and accumulator systems in major countries worldwide include those of the European Union. PED CE Standard 2014/68/EU , China TSG21-2016 , the United States, the Americas, and Africa, among other regions ASME Section VIII Division 1 , Brazil NR-13 Certification, Central Asia and the Far East – Customs Union Certification CU-TR , Australia AS1210 Wait.
With regard to the accumulators in the system, SCHWERLL The documentation demonstrating that the accumulator products comply with applicable standards includes: design qualification drawings, type‑test certificates, manufacturing licenses, product steel stamps, supervision and inspection certificates, and operating manuals, among others.
For the system’s gas safety valves and fluid relief valves, this includes: product verification certificates, product steel stamps, and other compliance documentation, among others.
In China, the nominal diameter of the gas pressure pipeline in accumulator systems shall be ≥ 50mm At that time, it falls under the category of pressure piping for special equipment and must be designed by a qualified entity, in accordance with the State Administration for Market Regulation’s Special Equipment Regulations. 2019 » 32 Requirements: Pressure vessel manufacturers that possess pressure vessel design capabilities or have obtained a separate pressure vessel design license may design pressure vessels of the same manufacturing grade as well as industrial piping systems connected to pressure vessels of that grade. SCHWERLL The company’s manufacturing facility holds design qualifications authorized by the Chinese government.
