14 1/2" diameter 225,000 lb. load Hydraulic Snubber
Piping Technology & Products, Inc. recently designed and manufactured a hydraulic snubber weighing 4000 pounds for an oil refinery in Mexico. The snubber is fabricated from carbon steel with dimensions of 17 x 101. It supports a maximum load of 225,000 lbs. The purpose of the hydraulic snubber is to reduce shock loading created by events such as water hammer or an earthquake. To meet customer specifications, the hydraulic snubber was coated with a three-coat paint system.

12,500 lb. Load Hydraulic Snubber and 24 Alloy Clamp Assembly
Piping Technology and Products, Inc. recently designed and manufactured a PTP Fig. 2100 Hydraulic Snubber and a Clamp Assembly for a power plant in California. The Hydraulic Snubber with a cylinder size of 2 1/2 dia. and a stroke of 5 is designed to support an operating load of 12,500 lbs. The 24 alloy clamp is designed to accommodate a temperature of 1078°F. The entire pipe hanger assembly was hydraulic tested prior to shipping.

14,000 lbs. Load Hydraulic Shock Snubbers
Piping Technology & Products recently designed and manufactured four fig. 2100 hydraulic shock snubbers for a refinery in California. Carbon steel was used to manufacture these snubbers. They support a maximum load of 14,000 lbs., have a 3” cylinder, and 5” stroke load. This was a custom job where the customer provided the figure number, cylinder size, and stroke load; we built the snubbers according to these specifications.

Hydraulic Snubbers for a Construction Site
Piping Technology & Products recently designed and manufactured three hydraulic snubbers for a construction site in Louisiana.
These snubbers, with an operating load of 3500 lbs., are 2.5 x 6 and allow for 4 of total travel distance. The lock-up velocity test was performed on these snubbers to make sure that at high rates of loading, especially impact, the snubber would provide very high resistance to movement. And, the drag test was performed to make sure that at low speeds they provide very low resistance to movement.

PT&P has been developing and testing a better hydraulic snubber during recent months. Final independent tests at a university laboratory are confirming our tests.
PT&P’s new snubber design features a spring-loaded cylinder in the hydraulic reservoir which feeds the main cylinder. This design is more compact, and it allows the snubber to be mounted in any orientation. With the addition of test equipment from our recent acquisition from the Basic Engineers Auction, PT&P plans to have these snubbers in production by the end of this year.
3D Models of PT&P Spring Hangers and Hardware are now available for Intergraph’s PDS Plant Design Software.

Hydraulic Snubbers Protect Critical Components In Refineries
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.

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.
