Custom Compact Springs Designed to Support a Storage Tank

PT&P partnered with Disc Spring Technology (DST) and is now manufacturing the compact spring support. Resolve your overloaded pump/ heat exchanger/ vessel nozzle loads with the DST Compact Spring Support. The DST Compact Spring Support is specifically designed to relieve excess loading on process equipment.

Benefits: Minimizes excessive loads on sensitive equipment, same load for smaller working range (25-50% less space), ideal for locating under equipment flanges & reduces design time, maintenance cost, and accidents.

Custom Compact Springs Designed To Support A Storage Tank

Type: Compact Spring Supports
Material: A-36 Carbon Steel | HDG | Stainless Steel
Design: 0.25″ Movement (upward) | 5,000 lb. Load
Testing: Load and Travel Testing

These compact spring supports were custom-designed to support a storage tank at a facility in Texas. The housing was fabricated from A-36 carbon steel and hot-dipped galvanized to protect them against corrosion. The disc springs are engineered using the stainless steel Belleville disc springs designed for large loads but small movements. In this case, the springs are designed to support a load of 5,000 lb. and movement of 0.25" (upward). The installed height can range from 5" to 10" depending on the client-specified load and movement. As a result, compact springs are ideal for "tight spaces" such as modular process skid mounted piping, machinery, and equipment for military and industrial applications. Disc springs can also be installed beneath rotating equipment (such as pumps and compressors) to help reduce or eliminate the transfer of vibration to associated steel and concrete structures. Each of these assemblies underwent load testing and visual inspection prior to shipment.

Mechanical Snubbers Designed for an Industrial Chemical Plant in Brazil

Mechanical Snubbers Designed For An Industrial Chemical Plant In Brazil

Type: Mechanical Snubbers
Size: Length: 40-3/8” to 60-3/4″
Material: Carbon Steel | Hot-dipped Galvanized | Paint
Design: 1,000 lb.  – 6,000 Load | Stroke: 4″ – 5″

Mechanical snubbers are designed to allow pipe deflection in tension or compression when operating under normal conditions, but if an impulse load occurs (such as a water hammer, earthquake, wind, or other transient forces), the snubber becomes activated and acts as a rigid restraint to limit pipe movement. So, in general, mechanical snubbers t have two modes of operation. In passive mode, the resistance mechanism is disengaged and the snubber “free wheels” with very low resistance. In active mode, the mechanism is engaged, and the snubber limits the acceleration to a low threshold value, becoming a rigid restraint. Mechanical snubbers are used in nuclear, geothermal, and other green energy plants, as well as, the traditional chemical, refinery, and power plants. Our superior design combined with rugged construction and corrosion-resistant parts makes these units extremely reliable for a wide range of loads and movements. Typically mechanical snubbers require no maintenance. Our team of engineers can also custom design and test snubbers to accommodate your unique application.

For this particular project, in addition to the mechanical snubbers, we also supplied pre-insulated cold supports, constants, variables, and rod hangers which were delivered ahead of schedule to meet the client’s delivery needs. PT&P and its subsidiaries design and manufacture the largest range of products for piping systems globally. With today’s supply chain considerations, projects can mitigate risk by working with a single strategic supplier and ensuring timely project completion and success. Our approach is unique.

U-Type Constant Spring Supports Designed for an LNG Plant in Canada

U-Type Constant Spring Supports Designed For An Lng Plant In Canada

PT&P designed U-Type constant spring supports for an LNG plant in Canada. These are horizontal constants designed to support piping from below where the base plate is bolted directly to the top of the steel or the foundation using anchor bolts. These specific constant springs are designed to support an operating load of 67,420 lb. with 6″ of total upward travel. The constants are fabricated from galvanized carbon steel for protection against corrosion. Standard load and travel testing were completed to ensure the quality and performance of these constants.
U-Type constant springs are commonly used in industrial applications where there is a need to support pipelines, ducts, or other structures subjected to thermal expansion or contraction. These springs are designed to provide a constant supporting force over a defined range of movement, typically in response to temperature changes. Here are some specific applications where U-Type constant springs might be used:

  1. Piping Systems: In industrial plants, refineries, chemical processing facilities, and power plants, pipelines are often subjected to temperature fluctuations due to the flow of hot fluids. U-Type constant springs can be employed to support these pipelines and compensate for thermal expansion or contraction, preventing excessive stress on the piping system.
  2. HVAC Systems: Heating, ventilation, and air conditioning (HVAC) systems often involve ductwork that expands and contracts with changes in temperature. U-Type constant springs can be installed to support HVAC ducts and accommodate thermal movements, ensuring structural integrity and preventing damage.
  3. Steam Systems: Steam distribution systems in industries such as power generation, food processing, and manufacturing also require support for piping subjected to thermal expansion. U-Type constant springs are used to maintain proper alignment and support in steam piping systems, preventing issues such as pipe stress and misalignment.
  4. Oil and Gas Pipelines: In the oil and gas industry, pipelines are essential for transporting crude oil, natural gas, and petroleum products over long distances. U-Type constant springs help support these pipelines and compensate for temperature changes, ensuring the reliability and safety of the transportation infrastructure.
  5. Process Equipment: Various types of process equipment, such as reactors, heat exchangers, and vessels, experience thermal expansion and contraction during operation. U-Type constant springs may be employed to support and compensate for the movement of such equipment, reducing the risk of damage and prolonging service life.

U-Type constant springs play a crucial role in maintaining the structural integrity and reliability of industrial systems and equipment subjected to thermal expansion or contraction.

Constant springs are sometimes installed near rotating equipment such as pumps and compressors used in manufacturing, mining operations, utilities, oil and gas extraction, and cross-country pipelines. By providing constant support to piping leading to rotating equipment subject to both vertical and horizontal movement, these types of spring hangers help to decrease stresses imposed on rotating equipment, thereby extending the life of the bearings and seals within these units.

In our continued efforts to meet projects needs for operationally best in class design with the lowest cost and time to market we created the world’s smallest constant spring support.

Nano Constant
We have designed and built constants for not only refineries, LNG, geothermal plants, petrochemical plants, and renewable energy facilities. The use applications include coker replacement, debottlenecking of furnace operations, installation of a new VDU (vacuum distillation unit) heater, tube, and heater replacement, and flare gas recovery units where the installation of constant spring hangers helped to improve the efficiency of the system or process.

Constant spring supports alongside our portfolio of products are shipped worldwide from our Houston, Texas headquarters, where all our products are manufactured. We are open for plant tours. If you are interested, please let us know so we can schedule some time with your team.

Variable Spring Support with Bronzphite® Slide Plates for a Facility in Canada

Variable Spring Support With Bronzphite® Slide Plates Designed For A Facility In Canada

PT&P manufactured these F-type variable spring supports for a facility in Canada. The springs are fabricated from A36 carbon steel with a hot-dipped galvanized finish. The variables installed heights range from 11" to 15" and are designed for operating conditions up to 4,000 lbs. Bronzphite® is best suited for high loads, low-velocity applications and where the use of oil or grease is undesirable or not feasible. The bronze plate acts as the bearing surface, withstanding heavy loads, while the graphite inserts provide a solid, oil-free lubricant. Type F base springs are not typically designed for lateral loads, so slide plates such as Bronzphite® are employed to reduce the stress that could be imposed on the spring and pipeline by reducing the sliding friction between the spring’s load flange and the pipe shoe, trunnion or supporting steel. Also added to these springs are Internally Guided Load Columns which provide additional support for lateral loads. As with all of our variable supports, these were quality-checked with a 100% spring coil deflection test and a load cell calibration to set the assembly at the prescribed installed load.

54" Dia. Pre-Insulated Pipe Shoes Custom Designed for a Pipeline in Texas

54&Quot; Dia. Pre-Insulated Pipe Shoes Custom Designed For A Pipeline In Texas

Pipe Shields/PT&P designed and manufactured pre-insulated pipe shoes for a 54″ diameter pipeline in a propane dehydrogenation unit within a chemical processing plant in Texas. The hot shoes are custom-designed with a wide base along with slide plates to accommodate lateral movement and axial movements of +/- 4 1/2″. We designed the hot shoes to include additional bolting along with bolting torque recommendations in order to help prevent slippage of the pipe inside the pipe shoe. We designed the supports to accommodate vertical loads up to 22,200 lb. and temperatures up to 1800°F. The outer part of the shoe was manufactured of hot-dipped galvanized carbon steel while the inner insulation material is 4″ thick high-density calcium silicate insulation.

Here’s a breakdown of their key purposes:

  1. Load Bearing and Movement: Insulated pipe supports are designed to carry the weight of the pipe while also accommodating necessary movement. This is important to prevent stress on the piping system and ensure its longevity.
  2. Insulation: In areas where regular pipe insulation cannot be installed, such as at support points, high density insulated pipe supports can both support the vertical load while providing a layer of insulation. This helps to maintain the temperature of the fluid flowing through the pipes and minimizes heat loss.
  3. Cost Efficiency: By reducing heat loss and minimizing the need for additional insulation materials, insulated pipe supports can help minimize the overall cost of field installation. Additionally, their pre-assembled nature saves installation time, further contributing to cost efficiency.
  4. Non-Welded Design: Unlike traditional supports that may require welding to attach to the pipe, insulated pipe supports are not welded. This simplifies installation and reduces the risk of damage to the pipe or insulation during the installation process.
  5. Shipment as Fully Assembled Units: Insulated pipe supports are typically shipped as fully assembled units, except for certain types like riser supports and anchor supports, which may require some welding during installation. This pre-assembly reduces the need for on-site assembly and ensures consistency in quality across installations.

Overall, insulated pipe supports offer a comprehensive solution for maintaining thermal efficiency, structural integrity, and cost-effectiveness in piping systems.

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 ranging 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.

Most hydraulic snubbers have a piston which is relatively unconstrained in motion at low displacement rates. At high displacement rates the piston "locks up", that is, the force required to move the piston increases substantially, usually as a result of the closing of a valve.

Hydraulic snubbers are used in many applications and are typically needed urgently in operational facilities. We have provided these products in all major verticals including refining, petrochemical, renewables, and power operations.. Our hydraulic snubbers are built in accordance with ASME Boiler and pressure vessel code and our Laconia, New Hampshire operations have ASME Nuclear Stamp "NS" for nuclear applications.

600,000 lb. Load Mega Ton Spring Support with Bronzphite® Slide Plates

600,000 Lb. Load Mega Ton Spring Support With Bronzphite® Slide Plates

A total of eight big ton spring supports, “Mega Tons” were designed and manufactured to support two reactors in a power plant weighing approximately three million pounds each. The mega ton pictured incorporated eighteen individual spring coils to produce a load capacity of approximately 602,000 lb. and a spring rate of 112,500 lb./in. It was designed with eight Bronzphite® slide plates that measured 12″ x 12″. The 12″ x 12″ slide plate selection was based upon the ability to position individual squares across the load flange surface while simultaneously providing the total slide plate surface area required to support the operating loads.

By using individual slide plate squares, the fabrication and assembly time was reduced because a standardized mounting procedure could be incorporated and repeated as necessary for each big-ton load flange subassembly. Overall, the slide plates were incorporated into the design to reduce the horizontal forces which would be imparted onto the big-ton spring’s load flange during lateral deflection (movement) of the reactor.

600,000 Lb. Load Mega Ton Spring Support With Bronzphite® Slide Plates

Bronzphite® slide plates, in particular, were selected because these big-tons will be used in a location which will see continuous “cold-to-hot” operating cycles and as a result, the robust nature of Bronzphite® proved more advantageous than other types of slide plates. The other two designs used nine slide plates, one with fifteen individual coils to produce an operating load of 594,000 lb. and a spring rate of 250,050 lb./in. The other design had an operating load of 285,000 lb. and a spring rate of 106,000 lb./in.

In addition to designing and manufacturing the Mega Ton spring supports, we were tasked with testing them to confirm they would operate in the actual conditions for which they were designed to operate at the requested loads. Therefore, we custom designed and manufactured a test apparatus and incorporated the use of a special load cell to ensure proper operation throughout the entire working range of the coils. The “mega tons” were then set to the cold (installed) load as specified. Testing was developed and done by our in-house manufacturing, quality and engineering teams.

Engineers often specify Pipe Shields and PT&P products as the foundation for designing various piping systems.

Last year we built over 50,000 units of this kind of support in our Houston-based manufacturing facility. We were the first in the industry to employ the use of high-speed manufacturing automation to facilitate the cutting of the high-density calcium silicate to meet tight deliveries required for the projects. The advent of computer-controlled cutting equipment has improved how we do things at PT&P. Integrating these advanced technologies has led to significant improvements in manufacturing processes, enabling unparalleled accuracy in cutting high-density insulation. Computer-controlled cutting equipment allows for intricate and complex designs that were once challenging or impossible to achieve manually. Automating cutting processes has not only reduced human error but also enhanced productivity by accelerating production speeds. Moreover, these systems provide a high level of repeatability, ensuring consistent quality across multiple iterations. Another benefit was that we were able to reduce the material waste generated by human cutting by roughly 10-15%, which allowed us to remain price-competitive on a global scale.
