March 28th, 2011 No comments

Custom Elevated Pipe Shoe-Clamp Designed for a 12" Diameter Transfer Line in a Polymer Plant

PT&P designed and manufactured custom elevated pipe shoe-clamp supports for part of a palletizer transfer line in a polymer plant. The custom supports were designed to prevent cracking in the welds and grout base due to severe vibration in the line. The assemblies have an overall height of 48″ with an adjustable load column. The clamp-shoes are 13″ wide by 14″ long, and designed for a 12″ diameter aluminum pipe. The assemblies are carbon steel with a hot-dipped galvanize finish and include a unique laminated vibration dampening lining for the clamp.

G-Type Variable Spring Support Assemblies for an Expansion Project at an Oil Refinery

March 14th, 2011 No comments

G-Type Variable Spring Support Assemblies for an Expansion Project at an Oil Refinery PTP-2 Type-G variable spring support assemblies were designed and fabricated for an expansion project at an oil refinery. The G-type spring is comprised of two standard variable spring housing-coil subassemblies joined together with an intermediate bridge assembly. The bridge assembly is customized to match existing site conditions, which allows for use in applications with limited space or interferences. This particular assembly was provided with extra large channels because the specified C-C dimension of 59″ exceeded the maximum (48″) of our standard G-type variable springs. The housings, internal components and channels were fabricated from carbon steel, and spring steel was used for the coils. The assembly was designed for a total operating load of 24,014 lb. with a design travel of 0.76″ upward.

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.

Pedestals and Beams in Operation

The 54″ suction line carrying gas to a gas compressor at a rate of 1.7 million lb./hr. developed a severe vibration. The deflections in the line were up to 3/4″ and it was fully observable during operation.

PT&P designed and manufactured a special elevated hold-down clamp, including a unique laminated vibration dampening lining. The entire pipe hanger assembly stands 22′ high and is coated with a carboline zinc finish. After installation and resumption of operations, the vibrations are now almost imperceptible.

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.
