Hydraulic Snubbers for an Ammonia Plant in Louisiana

Type: Hydraulic Snubbers
Design: 3,000-15,400 lb load/5″-12″ stroke
Material: Carbon Steel
Size: 31″ up to 148″ pin-to-pin and cylinder diameters from 2.5″ to 5″

Piping Technology & Products designed these hydraulic snubbers for an ammonia plant in Louisiana. The snubbers ranged in length from 31″ up to 148″ pin-to-pin and cylinder diameters from 2.5″ to 5″. They are designed for an operating load raging from 3,000 lb. to 15,400 lb. and have a 5″ to 12″ stroke. Hydraulic snubbers are designed to protect the piping system when a sudden, heavy load is applied (such as an earthquake of high intensity), which can cause serious vibrations leading to damage and possible failure of the piping system.

Hydraulic Snubbers Designed for LLDPE Chemical Plant

These Fig. 511 AD long hydraulic snubbers were created for a linear low-density (LLDPE) chemical plant in Louisiana. The snubbers with two (2) rear brackets range in length from 34-⅝” to 49”. They are designed with spherical, self-aligning ball bushings that allow for + 5° of angular motion or misalignment.  The snubbers can handle maximum loads varying up to 5520 lb. Cylinder sizes are 1-½” and 2-½” and have a 6” stroke. The hydraulic fluid is petroleum based and the seals are a mix of buna-nitrile and polyurethane and the pressurized hydraulic reservoir allows mounting in any spatial orientation. The snubbers are painted with a primer that utilizes zinc filled powder manufactured by Tnemec. Ⓡ  The formulation for the primer is Series H90-97 | Tneme-Zinc.

Hydraulic Snubbers Designed for an LNG Facility in Texas

Fronek Anchor/Darling Enterprises, a division of PT&P, designed snubbers for a LNG facility in Texas. These Fig. 511 AD hydraulic snubbers range in size from 76″ – 85″ piston-to-piston and are fabricated from carbon steel. They are designed for a maximum load of 32,000 lb., 6″ stroke and have a 4″ diameter cylinder. Hydraulic snubbers are designed to protect the piping system when a sudden, heavy load is applied (such as an earthquake of high intensity), which can cause serious vibrations leading to damage and possible failure of the piping system. A cycle test throughout the full stroke from zero to fully extended was performed prior to shipment

7 Ways to Extend the Lifespan of a Hydraulic Snubber

March 9th, 2012 Comments off

Follow these 7 steps below to maintain and extend the life span of your hydraulic snubber.

Hydraulic Snubber Assembly

1. Observe the fluid level to make sure there is sufficient fluid for the snubber to operate
2. Check for leaks – If the fluid level is decreasing, determine the cause and effect remedial action.
3. Check the condition of the load pins and spherical ball bushings. Apply a high pressure grease for long-term benefits.
4. Check the condition of the exposed portion of the piston rod. Check for scoring, paint or other physical damage.
5. Check the condition of the piston rod wiper. Verify that it’s in position and working effectively.
6. Check for evidence of abuse like welding arc strikes, bent or dented parts, scratched paint, etc.
7. Finally, check the overall physical appearance. This encompasses all of the above.

Hydraulic Snubber vs. Mechanical Snubber

March 11th, 2011 No comments

Have you ever wondered which type of  snubber to select for your piping system? Should you pick a hydraulic snubber or should you pick a mechanical snubber? Which one is right for your application? This seems to be a common concern for quite a few of our customers, so we have just recently published an article that discusses the pros and cons for both hydraulic and mechanical snubbers.  Check out the article, Suitability of Snubbers for Various Applications.

Hydraulic Snubbers (Fig. 511 AD) with Protective Boots Designed for a Hydro-sulfuric Acid Environment in a Geothermal Power Plant   Hydraulic Snubbers (Fig. 511 AD) with Protective Boots Designed for a Hydro-sulfuric Acid Environment in a Geothermal Power Plant

Fronek Anchor/Darling, a division of PT&P, designed and manufactured hydraulic snubbers with protective boots for a hydro-sulfuric acid environment in a geothermal power plant. They measure 53-5/8″ pin-to-pin with a 3-1/4″ cylinder bore size and 6″ stroke.

The snubbers are designed for an actual load of 15,400 lb., but have a rated load capacity of 20,000 lb. They are fabricated from carbon and alloy steel, and include two coats of epoxy-based paint. An activation velocity test was performed, along with a release rate and drag characteristics test.

Hydraulic Snubber Assemblies for a LNG Processing Facility in Peru

Hydraulic Snubber Assemblies for a LNG Processing Facility in Peru

These hydraulic snubber assemblies were designed with maximum load capacities ranging from 1700 lb. to 59,400 lb. All of the snubbers were provided with an overall stroke of 6” and were preset to the midpoint of the total stroke, meaning that during operation, these snubbers could accommodate piping deflections of  +/- 3” from the installed position.

The piston diameters range from 1-1/2″ to 6″ and the total assembly length ranges from 31-1/2″ to 220″. The largest assembly required a custom extension section to eliminate the risk of buckling under compression loads. Two-thirds of the assemblies included dual end brackets and the remaining assemblies included an end bracket/clamp combination. The housing, extension piece and end brackets are fabricated from carbon steel, while the cylinders, pins and two of the end brackets are fabricated from polished stainless steel. Standard “lock and bleed-down” tests were performed prior to shipping to a LNG processing facility in Peru.
