The Fronek A/DE Hydraulic Snubber is a manifold-designed hydraulic device that includes a high-pressure main cylinder, a flow control section with dual-stage velocity-sensitive poppet valves, and a spring-energized reservoir. These Fig. 511 AD long hydraulic snubbers were created for a linear low-density (LLDPE) chemical plant in Louisiana. The snubbers with two (2) rear brackets range in length from 34-⅝” to 49”. They are designed with spherical, self-aligning ball bushings that allow for + 5° of angular motion or misalignment. The snubbers can handle maximum loads varying up to 5520 lb. Cylinder sizes are 1-½” and 2-½” and have a 6” stroke. The hydraulic fluid is petroleum based and the seals are a mix of buna-nitrile and polyurethane and the pressurized hydraulic reservoir allows mounting in any spatial orientation. The snubbers are painted with a primer that utilizes zinc filled powder manufactured by Tnemec. Ⓡ The formulation for the primer is Series H90-97 | Tneme-Zinc. Ⓡ
Specific applications where hydraulic snubbers are commonly used include:
- Power Plants (Nuclear and Thermal): To protect piping and equipment from seismic events or pressure surges.
- Petrochemical and Oil Refineries: To mitigate damage from vibrations, pressure fluctuations, and thermal expansion.
- Industrial Piping Systems: To prevent failure due to dynamic forces like water hammer or large temperature swings.
- Bridges and Structures: To absorb and reduce the effect of seismic or wind-induced forces.
- Marine and Offshore Platforms: To protect against waves and operational vibrations.
Hydraulic snubbers are critical in environments where sudden forces could lead to catastrophic failures or damage. At both Fronek A/D and PT&P, we offer a wide range of experience and expertise in the manufacture and design of various pipe supports while maintaining a competitive price. We also offer 24×7 web-based emergency services, providing field service and quick turn-around time when you need it most.
