The photograph above shows hydraulic snubbers which are used to protect critical components in refineries, power plants and other industrial systems from sudden movement by the attached piping system. Engineers specify these devices for systems which are subject to sudden accelerations caused by earthquakes, extreme wind loads or water hammer. The insert at the upper left shows eight snubbers, some are different sizes and six have dust covers to protect the piston seal. The snubber at the bottom has hardware attached so it is ready to be installed. Hydraulic snubbers resist sudden rapid movement of the pipe by limiting the flow rate of the fluid inside the snubber. The device is designed so 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.

Compact or “Disc” Spring Support Live Webinar
Date: Thursday, October 21, 2021 – Register for 10:00 am or 2:00 pm
*Note: Time Zone is CDT * Central Daylight Savings Time / GMT -5h
Live Webinars are worth 1 PDH Credit for TX Professional Engineers
The Compact Spring Support Webinar will cover key objectives, background, and leading industry problems related to process equipment nozzles (both rotating and non-rotating equipment). First, we will review the challenges involved in the design and analysis of piping with respect to process equipment nozzles. Secondly, we will discuss the types of chronic problems and failures related to process equipment nozzles and present (or introduce) the Compact Spring Support as a solution. During our discussion, we will explain why chronic problems with process equipment exist, describing current design practices as they relate to industry code standards and how the Compact Spring Support addresses these problems directly and effectively. And finally, we will take a quick look at the technical data and sizing program.
