Shown above are hydraulic snubbers which are used to protect critical components in refineries, power plants and other industrial plants from sudden movement by the attached piping system. Engineers specify these for systems subject to sudden accelerations caused by earthquakes, extreme wind loads or water hammer. Hydraulic snubbers resist sudden rapid movement of the pipe by limiting the flow rate of the fluid inside the snubber. The device is designed to slow movement, such as would be expected during thermal expansion, has practically no resistance, but sudden rapid movement is resisted with a force proportional to the velocity raised to a power, where the power is determined by the orifice valve and flow pattern in the design. Selection of materials and liquids used will depend on the environment where the snubber is installed.

Variable Spring Support Design, Size Selection, Installation & Maintenance Webinar
*Note: Time Zone is CDT * Central Daylight Savings Time / GMT -5h
Live Webinars are 1 PE/PDH Credit for TX Professional Engineers
This Webinar will focus on the different types of variable spring supports and big ton variable spring supports. Learn about the special features available, in addition to the design of a variable support. View how the different coil configurations produce a unique response to an applied load and see how a spring assembly is loaded. Discover the basic steps in selecting a hanger design and the step-by-step process used to size a spring for your application. Learn about the different attachments, testing, and installation and maintenance procedures. View examples of failed supports provided by our Field Service Division and learn why they failed and how to prevent it. Gain knowledge of the valuable tips used when deciding to replace or re-calibrate a variable spring support, as well as adjustments, shutdown, and isolation procedures.
