Mechanical Snubbers

The two pictures above show mechanical snubbers which are used to limit the velocity of movement of piping systems when sudden accelerations caused by earthquakes, extreme wind loads or water hammer occur. These devices are designed with a brake drum which is activated by sudden movement. During gradual movement, such as would be expected during thermal expansion, the brake is not activated. Mechanical snubbers do not depend on hydraulic principles so they do not require maintenance during normal operation. The top picture shows the pins and swivel bearings used to link these snubbers to the system it will protect. The bottom pictures shows our inventory maintained for emergency deliver.

Hydraulic Snubbers

The two pictures above show hydraulic snubbers which are used to limit the velocity of movement of piping systems when sudden accelerations caused by earthquakes, extreme wind loads or water hammer occur. These devices are 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. The snubber at the bottom has a ball joint attached for linkage with the system it will protect.

Four “Ball Type” Flexible Strut Joints

Pictured above are four “ball type” flexible strut joints often used to help control vibration. These struts are attached to piping or other equipment to restrain movement in one direction while allowing movement in another direction. Movement may be due to temperature or pressure changes. Piping Technology & Products can furnish strut joints made from various materials and with various finishes depending on the load requirements and the environment where they will be installed.

Sway Struts for a 250 MW Power Plant

The picture seen above is a mechanical snubber attached to a rod with a pipe clamp. Below the snubber is a rigid sway strut for 36” pipe and four smaller sway struts. The snubber will dampen sudden shocks and vibrations in the piping system. These show the variety of built by Piping Technology & Products, Inc. for a 250 megawatt power plant.
