The American Institute for Steel Technology (AISTech) is North America’s largest steel industry trade show and one of the world’s leading industrial exhibitions. Held annually by the American Iron and Steel Institute, it showcases cutting-edge technologies from around the globe, helping steel producers compete more effectively in today’s global marketplace. For anyone involved in any aspect of the modern steel industry, AISTech is an unmissable event that offers invaluable insights into the technical and engineering expertise needed to advance a sustainable steel sector. Whether you’re attending as a visitor or exhibiting, take this opportunity to connect with industry peers and discover ways to boost productivity. With over 550 technical demonstrations, stay ahead in an ever‑evolving field and master the latest steel‑related innovations. AISTech 2025 enables face-to-face interactions with key decision‑makers and practitioners across the steel production and processing value chain. Invest in your career, expand your knowledge base and international network, and participate in Steel’s premier technology showcase. Rotating annually among different cities, the 2024 edition was held in Columbus, USA, attracting nearly 687 companies from 45 countries and regions, occupying 9,800 square meters of exhibit space. The event drew more than 8,000 professional attendees, including chairpersons, engineers, leaders, and managers. Chinese enterprises can leverage this platform to strengthen cooperation and trade with U.S. partners, tap into the North American market, enhance exchanges of industry‑specific technological information, and gain a deeper understanding of global steel industry trends—thereby elevating their own technological capabilities and operational standards.
Xivier energy‑storage technology products play a critical role in key stages of steel production, providing auxiliary and emergency power for essential processes such as blast‑furnace ironmaking, rolling, electric‑arc furnaces, continuous casting, steel‑tube extrusion, desulfurization and dephosphorization, bar production, and wire‑rod manufacturing. Thanks to their reliable performance, they have earned the trust of users.
On the step‑type furnace heat‑treatment production line, Xiwel has introduced an energy‑recovery hydraulic control system that further enhances product quality, reduces energy consumption, and makes a reliable contribution to achieving greater green productivity.

SCHWERLL has successfully completed the manufacturing of CNOOC’s super‑flow anti‑recoil valves and the associated super‑flow testing. The products have passed all performance verification tests and flow‑rate assessments, and have obtained certification from CCS, the classification society. Anti-Recoil Valve (AVR), also referred to in the industry as an anti‑backflow valve.
To meet the demands of operating conditions in vehicles, marine vessels, aerospace, and mobile applications—particularly where equipment weight or available installation space is constrained—SCHWERLL began, in 2025, developing miniaturized nitrogen‑boosting units based on its established standard designs. These compact units have been successfully deployed in nitrogen‑boosting systems for marine vessels and heavy‑duty vehicles.
What are the causes of severe pressure drop and shortened service life in bladder-type accumulators?
What are the causes of severe pressure drop and short service life in bladder-type accumulators? The structure of a bladder-type accumulator is quite simple, consisting mainly of an oil chamber surrounding the bladder and a gas chamber equipped with a gas‑tight seal. During operation, the hydraulic fluid must be connected to the hydraulic circuit; when the system pressure rises, the fluid flows into the accumulator, compressing the gas until the pressure in the system pipeline stabilizes.
How can we reduce failures when an accumulator malfunctions?
If an accumulator malfunctions, its performance will be directly affected, potentially leading to abnormal pressures and system failure. Therefore, it should receive close attention during routine operation, and appropriate measures must be implemented to mitigate risks. So, how can we minimize failures when an accumulator malfunctions? The following sections address this issue.
Accumulators are intriguing components in hydraulic systems, analogous to capacitors in electrical circuits or springs in mechanical systems. As critical energy‑storage elements, they serve a variety of sophisticated functions, including hybrid‑power applications, shock absorption, pressure stabilization (and sometimes flow‑rate regulation), and the rapid release of stored energy to simulate impacts.
Is a bladder-type accumulator suitable for use in series with gas cylinders or cylinder banks?
1. Bladders typically have a shorter service life than piston‑type accumulators, and their quality varies significantly among different manufacturers. 2. Many factors can shorten a bladder’s lifespan and lead to rupture, including variations in the bladder’s intrinsic quality and durability; improper handling during assembly (e.g., failure to pre‑fill with fluid for lubrication); incorrect procedures during pre‑charging (e.g., insufficiently slow inflation); errors in calculating the pre‑charge pressure; oil‑port flow velocities approaching or exceeding 7 m/s; single‑stroke reciprocation times of 10 seconds or less when used for energy storage; collisions between the bladder and check valves during operation; large temperature fluctuations (including significant seasonal differences); prolonged lateral vibration; fluid‑induced corrosion; and inertial impacts from minute solid contaminants in the working medium, among others.
