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.

Large Custom Sway Struts Designed for a Liquid Filters Manufacturer

October 31, 2011

Custom Sway Strut Assemblies

These custom fig. 2110, size 8 sway struts are for a liquid filters manufacturer located in Mississippi. Both sway struts have a 128,000 lb. load capacity and are fabricated from carbon steel with a hot-dipped galvanized finish. The sway struts measure 68-5/8″ long and have a 4″ diameter rod size. A load test was performed prior to an expedited shipping schedule of 1-1/2 weeks.

Mechanical Snubber Assemblies Custom Designed for an Oil Refinery

Mechanical Snubber Assemblies Custom Designed for an Oil Refinery

Mechanical Snubber Assemblies
This week’s feature is on mechanical snubber assemblies custom designed for an oil refinery in California. This project included twenty mechanical snubber assemblies with load ratings from 16,000 lb. to 40,000 lb. and lengths ranging from 65-1/2″ to 103-1/2″. Some of the snubbers were designed to double the standard stroke (up to 12″) by using two MSA-10 sized snubbers back-to-back. All the assemblies were custom designed by adding a carbon steel pipe extension piece. Load tests were performed and the assemblies were shipped in just under four weeks.

Hydraulic Snubber vs. Mechanical Snubber

March 11, 2011

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.

Snubbers: A General Overview

December 3, 2010

We recently posted a new Snubber article on our website.  It provides a technical look into both hydraulic and mechanical snubbers – how they are used in a piping system and how they function.  Most importantly, the article tells you the difference between various types of snubbers which is helpful in choosing the appropriate snubber for your piping system needs.

Hydraulic Snubber Assemblies for a LNG Processing Facility in Peru

November 1, 2010

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.

Custom Sway Braces with Ball Joints for a Refinery

July 6, 2010

Custom Sway Braces with Ball Joints for a Refinery

28 sway braces were custom designed from a combination of carbon steel and A-5160 spring steel. Custom design and fabrication was required due to the design loads and movements exceeding the largest standard sway brace assembly. The application required ball joint ends because the angle of incline exceeded the maximum five degree angle. The largest of the sway braces was designed for an operating load of 10,000 lb. with a travel range of 5″ in either compression or extension. Each sway brace was load and travel tested prior to shipping to ensure functionality throughout the entire travel range.

The sway braces will be used in pairs to support a 72″ diameter cooling tower supply line via a common attachment point. The internal components and housing are fabricated from carbon steel, and A-5160 spring steel was used for the coil. Each sway brace has a spring rate of 10,100 lb/in. with an overall available travel of 3″. The adjustable ends are configured so that one end bracket is interlocked with the mating end bracket of its sister sway brace; therefore, enabling them to be connected to the pipe by a single lug.
