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.

Hold-down Clamp in 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.

Large Custom "Sling" Support and Horizontal Traveler Assemblies for an Oil Refinery

Three custom “sling” support assemblies fabricated from stainless steel were designed for an oil refinery in Louisiana. The assemblies are comprised of a 79.25″ diameter custom saddle support and two horizontal travelers (Fig.270 PTP-4). They are capable of loads up to 44,000 lb., and were designed, fabricated and shipped in four weeks for expedited delivery.

Structural Supports Coated with Red Oxide Primer for a Power Plant

September 1st, 2010 No comments

Structural Supports Coated with Red Oxide Primer for a Power Plant

The structural pipe supports are fabricated from carbon steel and coated with red oxide primer. The structural steel will be stored in a warehouse for several months while the power plant is being built. Due to the plant’s location along the United States East Coast, the use of the red oxide primer was selected. Also, modifications were made to our standard “insulation saddles” to allow for a higher load capacity; which can be seen in the foreground of the image above.

22″ Dia. Riser Clamps

22″ Dia. Riser Clamps

All four riser clamps are manufactured from A-36 carbon steel plates and are coated with red oxide primer for rust prevention. They are 22″ in diameter with each plate measuring 2″ thick by 12″ wide by 65″ long. Each riser clamp is capable of supporting loads of up to 38,000 lb. and will be used in a power plant to support “downcomer” lines.

Billet Style Clevises & Turnbuckles for Temperatures up to 1000ºF for a Power Plant

December 8th, 2009 No comments

 

Billet Style Clevis

Billet Style Clevis

The clevis and turnbuckle pictured are each fabricated from individual solid pieces of 304H stainless steel. The 304H material, which has a maximum carbon content of 0.06%, was required because these items are designed to be used in an environment with temperatures up to 1000ºF. The customer’s specifications mandated that no welding would be allowed on either the clevises or turnbuckles. Additionally, no forgings were readily available, so blocks of 304H stainless steel were utilized in this design.

Billet Style Turnbuckle

Billet Style Turnbuckle

Both the clevises and turnbuckles are made to accommodate rod diameter ranges between 1-1/4″ to 1-3/4″. These components have a maximum load capacity of 18,600 lb. The clevises measure 3″ thick x 5-1/4″ wide x 10-5/8″ tall. The turnbuckles measure 2″ thick x 4″ wide x 9-1/4″ tall. Prior to fabrication, each component was modeled using finite element analysis to determine that stress levels are within the acceptable range.

Neoprene Lining

The riser clamps are 54″ in diameter and custom designed to be installed in the Emission Control Unit of a 1600 MW coal fired power plant in Texas. The clamps include neoprene lining adhesively bonded to the carbon steel to protect the FRP pipe. Prior to assembly, the riser clamps received a coat of Red Alkyd Primer to prevent rust and resist moisture and corrosion.

Side View of Pipe Saddles

PT&P custom designed seventy-eight figure 2000 heavy duty pipe saddles for two 24″ insulated ductile iron pipelines. The two pipelines are routed beneath a 650′ bridge crossing over a river in upper New York State. The insulation is 3″ thick with high density polyethylene jacketing. Axial movements due to expansion can approach 3″. In order for the jacketing to avoid being damaged when displacements occur, the saddles have been lined with polished stainless steel.
