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 3rd, 2010 No comments

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 1st, 2010 No comments

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.

Hydraulic Snubber Assemblies for a LNG Processing Facility in Peru

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

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.

Custom Sway Brace Supports

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.

Hydraulic Snubber (Item #1)

Fronek Anchor/Darling Enterprises, Inc. and PT&P designed and fabricated hydraulic snubber and 3-bolt clamp assemblies for a refinery expansion project in Louisiana. A cycle test throughout the full stroke from zero to fully extended was performed prior to shipping.

Item #1: C-C: 61″, stroke: 12″, cylinder size: 5″ dia., max. load: 50,000 lb., 3-bolt clamp: A240 Gr. 304 SS, pipe size: 12″

Item #2: C-C: 71-7/8″, stoke: 6″, cylinder size: 4″ dia., max. load: 30,000 lb., -bolt clamp: A-36 carbon steel, pipe size: 16″

Item #3: C-C: 85-5/8″, stoke: 6″, cylinder size: 4″ dia., max. load: 30,000 lb., -bolt clamp: A-36 carbon steel, pipe size: 16″

48 Sway Braces for a Refinery Expansion Project.

48 Sway Braces for a Refinery Expansion Project

48 Sway Braces for a Refinery Expansion Project

The carbon steel sway braces for this project range in length from 88-3/8″ to 95-3/4″. The largest sway brace has an operating load of 18,000 lb., a design travel of 12″ in either compression or extension, and a spring rate of 1416 lb. per inch. The smallest sway brace has an operating load of 7000 lb., a design travel of 8″ in either compression or extension, and a spring rate of 1000 lb. per inch.

The anticipated loads and movements exceed those of the largest standard PT&P sway brace; therefore, these sway braces required a custom design and fabrication. Each of the 48 sway braces are configured with a unique combination of spring coils, housings, and internal components to accommodate the non-standard loads and movements.

Sway Strut Assemblies with Custom Designed 3-Bolt Pipe Clamps

These sway strut assemblies are designed in conjunction with custom three-bolt clamps to prevent movement on the pipeline. The sway struts range in length from 25″ to 70″ from pin to pin. The operating load ranges between 8,000 lb. to 15,000 lb. The clamps are designed for pipe sizes ranging from 8″ to 24″. The sway strut assemblies are fabricated entirely from carbon steel with a hot-dipped galvanize finish. The completed assemblies also include a custom 2-coat paint system that was applied over the galvanize finish before being shipped to an LNG plant overseas.

Sway Braces

These PT&P sway braces are fabricated from carbon steel and measure 126″ from pin to pin. They use an integral piston assembly with guide to eliminate any buckling and/or misalignment during extension and compression. The sway braces are designed for 10 1/2″ of travel and a load of 1,500 lb. A combination of standard spring coils is used to achieve the required spring rate of 150 lb./in.

Prior to shipment, a test was performed using a hydraulic ram. This test simulated actual field conditions and allowed the sway brace to move through the entire travel range in both compression and extension modes.

Ball-Joint Sway Strut Assemblies (20,000 lb. load, 96″ long) for an Ammonia Plant

October 22nd, 2008 No comments
Ball-Joint Sway Strut Assemblies (20,000 lb. load, 96" long)

Ball-Joint Sway Strut Assemblies (20,000 lb. load, 96" long)

The overall length of each sway strut is 96 inches. The pipe hanger assembly is designed to control 20,000 lb. of piping load during the system’s thermal expansion and contraction.

These sway struts have a ball joint located at each end connected by an extension rod that controls the piping system through its complete range of thermal piping movements. It is used to restrain movement of piping in one direction while providing for movement due to thermal expansion or contraction in another direction.
