Product Description

Product Description

Fluid viscous dampers are primarily composed of cylinder, piston, piston rod, fluid medium and connectors. The cylinder is filled with the medium fluid and the piston divides the cylinder and the fluid into two sections. As the piston moves within the cylinder, the fluid flows from one section into the other, generating heat in the process.
Fluid viscous dampers are highly effective at dissipating seismic energy, and do not alter the stiffness of the structure. They can also be used to dampen vibrations caused by other factors, including wind, heat and traffic.
This product is in compliance with the following standards:

• "Dampers for vibration energy dissipation of buildings" JG/T 209-2012
• "Fluid viscous damper and lock-up device for railway bridges" TB/T 3561-2020

Company Profile

 

Hebei Ansha New Material Technology Co., Ltd. is located in Binhu New District of Hengshui City. We specialize in R&D and production of seismic isolation and damping products for both buildings and bridges. Our products include rubber bearings, spherical bearings, friction pendulum systems, fluid viscous dampers, tuned mass dampers, buckling-restrained braces, friction dampers and metallic dampers. In addition, we manufacture bridge expansion joints and fiber-enhanced plastic products.
We have established state-of-the-art physical and chemical laboratories and specialized production lines. Our company operates in full compliance with the ISO9001:2015 Quality Management System, ISO14001:2015 Environmental Management System, and ISO45001:2018 Occupational Health and Safety Management System.
Guided by the anti-seismic design principle of "resisting collapse in a major earthquake, enabling repair in a moderate earthquake, and remaining undamaged in a minor earthquake", we offer our customers a comprehensive array of services. These services include technical consultation, structural analysis and calculation, design optimization, research and development, manufacturing, installation guidance, performance monitoring, maintenance and repair.
