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.

Size: ¾” x 14” x 18” | Nelson Studs: ¾” x 7”
Material: HDG Carbon Steel
Testing: Visual & Q.C. Tests

PT&P designed and manufactured 157 embed plates for a construction company in Texas. Embeds are essentially anchor bars used to secure steel to the concrete. The plate is ¾” x 14″ x 18″, and the Nelson studs are ¾” x 7″. All components are fabricated from carbon steel with a hot-dipped galvanized finish. Visual and Q.C. tests were performed prior to shipment. This job was a 15-day turnaround in order to meet the customers’ construction schedule.

Embeds are usually set in concrete foundations, floors, or piers and are a key component in the construction industry for connecting steel to concrete. Virtually all “grass-roots” projects such as chemical, power, refinery, solar, food processing, mining, and green energy plants contain embedded steel as a part of its foundation. These can also be used in automotive, semiconductor, and now battery plants. We have the ability and knowhow to custom manufacture various sizes, types and can utilize different materials to meet our client specifications.

Our Houston based manufacturing operations allow us to meet tight delivery schedules at most project job sites allowing for cash flow management of the project and substantially reduced supply chain risk. Typically embeds and anchor bolts have time criticality considerations because the concrete construction teams must mobilize in a timely fashion so logistics and cost can be managed effectively.

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.

Constant Spring Supports Custom-Designed for a Large Crude Oil Processing Facility

Constant Spring Supports Custom-Designed for One of the Largest Crude Oil Processing Facilities in the World

Piping Technology & Products custom-designed constant spring supports for crude oil processing at one of the largest refineries in the world. Petroleum refineries change crude oil into products such as jet fuel, gasoline, polypropylene, polyethylene, propane, sulfur, carbon black feed, and diesel that can be used for transportation, heating, feedstocks for making other chemicals, generating electricity, renewable energy, and paving roads. Piping Technology and Products was awarded this project because we were the only engineering manufacturing firm vendor of constant spring manufacturers in the world that could both design, manufacture, and test these units for the unique design conditions. These constant springs will support loads ranging from 88,185 lb. to 143,300 lb. They are designed for temperatures up to 650°F, and movements of 0.39" up, 4.72" down, -2.36" up, and 0.39" down. The Type-C constants are 67" H x 21" W x 88.25" L and the Type-F constants are 85" H X 39.75" W x 86.56" L.

The F-Type springs will include graphite slide plates and are designed to support the piping from below while allowing both lateral and axial movement. All constant assemblies underwent magnetic particle inspection of welds, travel, and compression tests. Additionally, a special “cramp test” was conducted on each spring coil. A "cramp test" is done by compressing the spring coil by a specified length for a specific period of time. This assures the spring’s functionally especially when a large "wire diameter" is used to manufacture the spring coil for these high loads. At Piping Technology and Products and our subsidiaries, we specialize in designing pipe supports, expansion joints, and insulated supports for unique applications involving products not readily available. Our products are used in the CDU (crude distillation units), hydrocracking units, RFCC (residual fluid catalytic cracking), naphtha hydrotreater, and hydrodesulfurization units (also known as alkylation unit), and sulphuric acid regeneration (SAR) units in refineries.

Saddle Support Spring Isolators for an Old Steam Chest Saddle

Saddle Support Spring Isolators Designed for an Old Steam Chest Saddle

PT&P custom-designed and fabricated "saddle support spring isolators" to replace the previous springs originally designed in 1974 for supporting an old steam chest saddle at a chlor-alkali chemical plant. Chlor-alkali plants use salt and electricity to produce caustic soda and chlorine gas. Downstream, the chlorine gas – either wet or optionally dry – can be reacted in a chemical process to produce bleach, other chlorine derivatives, or chemical feed stocks finding its way into the production of glass, plastics, pulp, paper, textiles, vinyl, antiseptics, insecticides, and a water treatment agent and in some soaps and detergents. Rising demand for chlorine and caustic soda in various industries such as automotive, pharmaceuticals, paper, and chemicals are driving the chlor-alkali market. Due to improvements in the manufacture of spring coils, PT&P’s engineering team suggested improvements to the original design using a more well-suited design that exceeds the original design specifications. These saddle supports include PTFE, 25% glass-filled slide plates bonded to the top of the assembly. They are designed to support up to 32,000 lb. each with a 6,250 lb/in. spring rate. These springs do not have the traditional spring housing typically used to encase the spring coil, instead, they are fabricated utilizing carbon steel plates in conjunction with chains and internal components. See diagram below. Ptp spring isolators plain diagram 161917

The spring coils are alloy steel and were custom designed per this customer’s specified wire dia, active/total coils, and solid height. The spring supports were load tested and a quality control inspection was completed that included MAG Particle Inspection. PT&P can replace existing custom variable spring supports using the original design drawings from plants built more than 50 years ago. PT&P can also reverse engineer any spring hanger by taking detailed measurements of the support in the field and sending the information back to our shop for a quick lead time during a plant turnaround or shutdown. Many of the custom spring supports that PT&P has supplied to replace original equipment have been in service for more than 40 years.

36” Dia. Cryogenic Pipe Saddles Designed for a LNG Facility

36” Dia. Cryogenic Pipe Saddles Designed for an LNG Facility

PT&P custom-designed pipe saddles with micarta base insulation for an LNG facility in Australia. The saddles were fabricated from 304L stainless steel plates with thickness ranging from 1/8″ to 3/8″. The micarta blocks range in thickness from 1/4″-3″. The saddles were designed to support pipes up to 36″ in diameter at an operating temperature of -300°F. Standard Q.C. and dimensional tests were performed prior to shipment.

A pipe saddle is any pipe support that cradles a pipe and transfers the pipe’s load weight onto a supporting base. Much like a saddle on a horse supports a rider and keeps them from bouncing on the animal, pipe saddles support a pipe’s weight. Pipe saddles are commonly used on large-diameter piping where the load is exceptionally heavy or when contraction-expansion movement is expected. Pipe saddles are welded to the pipe and are used in conjunction with roller supports or on-beam supports.

With the current uptick in global LNG demand driving US-based LNG production, Piping Technology and its subsidiaries are well-positioned to support large-scale projects in a timely manner. Our engineering and production teams work closely with our clients to ensure site, operator, and design needs are met. LNG demand is positioned to continue to grow over 60% by 2035.

Compact Spring Supports Custom-Designed for Large Diameter Piping at a Chemical Plant

Compact Spring Supports Custom-Designed for Large Diameter Piping at a Chemical Plant

These compact spring supports were custom-designed to support large-diameter piping at a chemical plant that manufactures ethylene, propylene, butadiene, benzene, propylene oxide, styrene monomer, and other derivatives and gasoline-blending products. They are designed for large loads (13,623 lb. to 24,038 lb.) and a small confined space with limited thermal movement (from 0.2″ to 0.3″). Compact spring supports (or disc springs) minimize excessive loads on sensitive equipment, so these types of spring support the same load as a conventional variable spring but with a smaller “working range” and utilize 25-50% less space. They are ideal for locating under equipment flanges or other locations where space is limited. The housing is fabricated from A-36 carbon steel and hot-dipped galvanized to protect against corrosion. They have an installed height of 13″ – 15″ and are 21″ in diameter. The “disc springs” are engineered using stainless steel. Each assembly underwent load testing and other NDE before shipment.

Piping Technology & Products supplied these mechanical snubbers with two end brackets fabricated from carbon steel with an HDG finish for a refinery in Oklahoma. They are size MSA-10, 36" OAL, and 30 1/2" pin-to-pin. The snubbers are designed for an operating load of 15,000 lbs and have a 6" maximum stroke. Standard load tests were performed before shipment. Mechanical snubbers have two modes of operation. In passive mode, i.e., motion caused by thermal loads, the resisting mechanism is disengaged, and the snubber "free wheels" with very low resistance. The mechanism is engaged in active mode, and the snubber limits the acceleration of motion to a low threshold value.

In addition to refineries, mechanical snubbers are preferred for use in nuclear plants as they do not contain hydraulic fluids that could degrade over time. Mechanical snubbers are also used in chemical, power, and green energy plants such as solar and geothermal. Mechanical snubbers are also used in earthquake zones to limit shock or sway caused by seismic disturbances.

In addition to the products we offer, we also have an experienced field service team. Over 80% of the field service we do is for engineered supports, including constant and spring supports. Inspecting pipe supports in high-energy piping systems such as refineries, chemical plants, and power plants is critical for ensuring safety and reliability. Neglecting these inspections can lead to major consequences detailed below:

  • Structural Failures: Over time, pipe supports can weaken due to corrosion, vibration, or other factors. Without inspection, undetected defects can result in the failure of these supports, causing pipes to sag, bend, or even rupture. This can lead to catastrophic accidents and expensive repairs.
  • Leakage: When pipe supports degrade, they may cause pipes to shift or disconnect, leading to leaks at flange connections and other types of connections in high-pressure systems caused by pipe strain. These leaks can release hazardous substances, causing environmental damage, health risks, and operational disruptions.
  • Reduced System Efficiency: Improperly supported pipes can experience increased friction, causing higher energy consumption to maintain the desired flow rates. This inefficiency can result in increased operational costs and decreased overall system performance.
  • Loss of Containment: In high-energy piping systems, failure to inspect supports can compromise containment integrity. A pipe rupture or leak called a “failure in the pressure-containing boundary,” can release hazardous materials, posing serious risks to personnel, nearby communities, and the environment.
  • Regulatory Non-Compliance: Many industries are subject to regulations and standards governing the inspection and maintenance of high-energy piping systems, including ASME B31.1 and 31.3 and API570. The implications of non-compliance can result in legal consequences and fines.
  • Increased Maintenance Costs:With regular inspections, minor issues can be managed so they do not escalate into costly and timely major problems such as extensive repairs or complete system replacement.
  • Loss of Productivity:Unexpected failures and repairs can disrupt production schedules and lead to unplanned downtime, causing financial losses and impacting the company’s reputation.

Correct installation and regular inspections are essential to mitigate risks and ensure industrial facilities’ safe and efficient operation. We have a team of engineers and technicians who are qualified to inspect pipe supports and expansion joints and can assist with diagnosing problems, replacement, and identifying models, types, and sizes. We provide field service to our clients for all product categories we manufacture, even if we are not the OEM because serving our clients is our first priority.

Custom-Designed Hot Shoes

Hot Shoe Custom Designed for a 16-inch pipeline for a mining facility in the Caribbean

Type: Pre-Insulated Pipe Supports “Hot Shoes”
Size: 18″ Length | 16″ Dia. | 4″ Insulation
Material: A240 Gr. 304 L Stainless Steel | Firetemp®
Design: 25,000 lb. – 50,000 Load
Testing: Standard Q.C. Inspections

Piping Technology & Products, Inc. designed and manufactured pre-insulated pipe supports for a high-temperature pipeline for a gold mine. Our subsidiary, Pipe Shields, created this category and family of products.

The “hot shoes” are 16″ in diameter, including 4″ of insulation, and are 18″ in length. They are fabricated from A240 Gr 304 L stainless steel and high-density calcium silicate insulation. The insulation material is noncombustible and can be supplied in varying densities to accommodate different loading applications. This type of insulated support is also utilized in lithium battery plants, automotive manufacturing, data centers, semiconductor manufacturing facilities, sports stadiums, hospitals, and other facilities where there are high-temperature pipelines. In many cases, these lines are for chilled water, hot water, and HVAC systems. These hot shoes are custom designed to support loads from 25,000 lb. to 50,000 lb. at an operating temperature of 1,400°F. Standard tests were performed for a three-week rush job.

For this particular project, we provided a larger scope of material in addition to the pre-insulated supports shown here. We worked with the pipe module fabricator and the EPC for the same project. The scope of material and services included engineering services, insulated supports, pipe hanger hardware, clamps, rods, guides, anchors, structural bolts, nuts, and washers. The project dates back to 2010; however, this mine has last year undergone a plant expansion and mine life extension project designed to increase throughput and allow the operation to maintain a minimum annual gold production of approximately 800,000oz until 2040.

We regularly support customers for the life of their facilities, sometimes over 40 years. We see every customer relationship as long-term and strategic so we can be part of their continued success.
