SECTION FHYDRAULIC SNUBBERS

Supplementing the scope of this support catalogue, Pihasa makes this type of basic element in theadvanced design of piping systems available to the market.

These hydraulic snubbers are components that protect pipe systems from unwanted dynamic efforts,such as: earthquakes, pressure shock, effects of wind, physical impacts, breakages, explosions, suddenpressure increases due to the release of safety valves, water hammers, etc.

Furthermore, the hydraulic snubbers that we supply have an added function of dampening vibrationswhen they comply with the following conditions:* Amplitude greater than 0.5 mm.* Frequency in the range of 1 to 33 Hz.

The use of snubbers makes it possible to reduce the amplitude of unwanted dynamic movements. At thesame time, snubbers make it possible to shift the piping due to thermal dilation, giving a very small frictionload (free flow condition).

When the speed of the piston increases above the nominal blocking speed value (standard 2 mm/sec.,adjustable to 6 mm/sec.), the block valve shuts off, preventing movement and absorbing the forcesbuilt up (blocking condition).

In alternative movements (vibrating waves), the two blocking valves open and shut off, alternating,opposing resistance in each direction in which there is an equal load capacity.

In order to ensure piston movement under load at a controlled speed and also to alleviate the pressureon the control valve, the snubbers are fitted with the same number of needle valves or relief valvesthat allow the flow to make a controlled bypass. The needle valves are calibrated to limit piston speedto below 2 mm/sec.The snubbers incorporate a hydraulic fluid reserve tank, pressurized by loading a spring. This internalpressure ensures that no air enters during the operating process and that the tank can be installed inany position and orientation.

CHARACTERISTICS AND ASSEMBLY:

The hydraulic snubbers can be fitted into any installation position. Thermal displacement of the pipingshould be taken into account, either in terms of extension or in terms of compression, in order to ensurethe maximum margin between the nominal and the actual travel. This amounts to assembling them whenthe travel is greater than 25% of the nominal travel, with the piston compressed or extended at a valueequal to the half thermal displacement expected with extension or compression, respectively.

CHARACTERISTICS AND ASSEMBLY:

Rolling resistance / Friction ...................................... max. 2% of nominal load.Response speed ...................................................... 2-6 mm/sec.Post-reaction speed ................................................. 0,2-2 mm/sec.Frequency range ...................................................... 1-33 Hz..

The elements in the exterior housing are manufactured in high quality electro-galvanized treated carbonsteel (15 µm thickness). Additionally, the piston is coated with a 40 µm nickel base electrolytic layer.On special order, they can be manufactured in stainless steel.

STANDARD FINISH:

MAINTENANCE:

Metal parts are designed to have a life cycle of 40 years, but however, the organic parts, such as fluidand joints, are subject to a greater ageing process, the more unfavourable the operating conditions are.Depending on where they are located and their use, joints and fluid may have to be replaced after 20years of operation. The following is advisable:

* Annual inspection to check on the piston level in the reserve tank.* After 10-15 years, a functional test on the test bench.* After 20 years, replace hydraulic fluid and joints.

TEST PRIOR TO SUPPLY:

All snubbers are subjected to functional tests prior to dispatch, in order to obtain the standardoperational values.
