PT&P Manufactures and Installs an 85 ft. Pipe Rack and Pipe Spools

PT&P supplied “on-time delivery” of two industrial structural steel pipe racks and the accompanying pipe spools that would be attached to storage tanks measuring approximately 120 ft. in diameter and over 85 ft. tall. Pre-Engineered Pipe Racks attached to storage tanks are used in a wide range of industries from Waste Water Treatments plants, Community Water Storage Tanks, to Above Ground Storage Tanks used in Refineries, Natural Gas, and Petrochemical plants.

PT&P leveraged its breadth of manufacturing and engineering capabilities to reduce costs for its client in the deployment of this Pipe Rack. Our focus was to complete as much work as possible in our production facility, where costs are typically far lower than in the field. We made adjustments to the design to aid in-field deployment to minimize total overall costs. This project also leveraged our capabilities with structural steel, pipe spools, TPI, and insulation. We have all of these capabilities in-house, which made it easy to fabricate the complex structures in this project.

Each pipe rack had an overall dimension of 12 ft. wide and 113 ft. tall and was fabricated from carbon steel. Due to the overall length, each frame was fabricated in two sections in our shop in order to transport each to the job site. Additionally, each frame was provided with lifting lugs designed by PT&P to facilitate both, the transporting of each frame half-section and the subsequent vertical lift of each completed unit. Each pipe rack was fitted with 9 pipe spools ranging in diameter from 2″ to 12″ (6 were insulated pipe spools, and 3 were non-insulated pipe spools). The pipe material used to fabricate the pipe spools were SA-53, SA-106, and SA-333.

Six of the pipe spools were supplied pre-insulated. At the ends of each section of the pipe spool, there were bare sections of pipe where PT&P Field Service would later perform “tie-in welds” in the field.

After completing shop fabrication, the pipe racks were prepared to be transported to the job site location for final assembly before installation by PT&P Field Services. This consisted of bolting the two halves of the pipe rack together and completing the “tie-in welds” at each pipe spool connection. All of the “tie-in welds” were examined and verified by X-ray analysis. After completion of all the “tie-in welds”, PT&P Insulation Department installed insulation in the field on the 6 pipe spools requiring insulation at these connection points.

Rigid Rod Hangers

Each section of the pipe spool was supported from the top of the rack by a rigid rod hanger also supplied by PT&P. Rod hanger assemblies are round steel bars normally threaded and used to connect other components, such as pipe support hardware, to make a pipe hanger assembly. PT&P’s field service team installed the main pipe rack with seven pipe spools each over 86 ft. long on large storage tanks. The pipe spools were positioned on the pipe rack steel using special U-bolts to “guide” the piping.

U-bolts are u-shaped rods with threaded ends that fit around a pipe and are attached to a supporting member. These U-bolts were coated in plastic to prevent corrosion between the pipe and the U-bolt material. Additionally, Thermal Plastic Isolators (TPI) were also used to prevent corrosion between the pipe rack steel and the pipe spools. TPI can be customized in height, width, length of TPI, hole sizes, hole locations, and special shapes.

Testing: Standard Load Testing & Q.C. Inspection

Variables use coiled springs to support a load and allow movement. The resistance of the coil to a load changes during compression, which is why these devices are called "variables". We offer a variety of different designs of variable spring pipe supports. View Variable Spring Supports Product Section.
For this application, the variable spring with rollers were used in natural gas compressor stations in Texas. Compressor stations are an essential part of a natural gas pipeline that moves natural gas from one location to another. At these stations, natural gas is re-pressurized and sent back into the pipeline system where it travels until the next compressor station. The location and distance between compressor stations is dependent on terrain, and the number of gas wells in the vicinity. Frequent elevation changes and a greater number of gas wells will require more compressor stations.
The compressor station, also called a pumping station, is the "engine" that powers a long-distance natural gas pipeline. As the name implies, the station compresses the gas (increasing its pressure) thereby providing energy to move it through the pipeline. The compressor is driven by a motor fueled by some of the natural gas bled from the pipeline. The size of the station and the number of compressors (pumps) varies, based on the diameter of the pipe and the volume of gas to be moved.
Piping Technology and Products and its subsidiaries provide products and services to this critical piece of the energy infrastructure with not only variable spring supports with rollers showcased here, but also with insulated supports, expansion joints, pipe shoes, guides, and anchors.

Custom Designed Constant Spring Supports for a Chemical Plant in Singapore

Type: Constant Spring Supports
Size: 15-¼” W x 17″ H x 46″ L with 9-¼” OD
Material: Carbon Steel | Hot-dipped Galvanized
Design: 2,379 lb. Load | 10″ Upward Movement

PT&P custom designed and manufactured constant spring supports for a chemical plant in Singapore. The constants are fabricated from A36 carbon steel and include alloy coil springs. The dimensions are 15-¼” W x 17″ H x 46″ L with 9-¼” OD. They were designed for an operating load of 2,379 lb. and movement of 10” upward and were specially designed to incorporate “telescoping spring coil housings ” and painted to protect against corrosion. Standard load and travel tests were performed prior to shipment. As part of the standard quality control process, we test every constant that we build before it is shipped. We are ISO-9001:2015 Certified by DNV GL. Last year we built over 1500 constants alone for our customers. Some were designed to support loads up to 150,000lbs with movements over 48 inches.

These specific constants were for a plant that manufactures industrial gasses such as hydrogen, carbon monoxide, and synthesis gasses. Constant spring assemblies are used in a variety of applications ranging from CDU (crude distillation units), hydrocracking units, RFCC (residual fluid catalytic cracking), naphtha hydrotreater and hydrodesulfurization units (also known as alkylation units), and sulphuric acid regeneration (SAR) units in refineries, LNG, Geothermal, Coker units, HRSG units, and other facilities where there is substantial thermal growth in the piping. They can be configured to accommodate horizontal or vertical movement.

Constants use a spring coil (or set of coils) to accommodate pipe movement from the initial (installed) condition to the final (operating) condition of the piping system. For all constant spring supports there is no difference in the load to be supported. Instead, these spring supports are designed to accommodate movement due to thermal expansion or contraction. PT&P has set up its manufacturing department to offer an unparalleled set of customization options with minimal impact on delivery timeframes. In addition to our standard (hot-dipped galvanized, neoprene coated spring coils) variable spring supports, we can customize any material, finish, dimension, load, load adjustment, travel, travel stops, and provide sensors for remote monitoring.

Compact Springs for a Chemical Manufacturing Plant for Agriculture

Compact Spring Supports Custom-Designed for a Chemical Manufacturing Plant for Agriculture

Compact spring supports (also known as disc springs) were custom-designed for a chemical plant in the agricultural industry. We design each compact spring for specific applications. Usually, they are used in “tight” spaces where the conventional variable spring is too tall to fit the allowable space between the pipeline and supporting steel structures. In general, compact springs serve the same function as a conventional variable spring, to relieve vibration and stress in the pipeline and associated equipment. The springs supplied here are designed for loads ranging from 5,038 lb. to 15,144 lb. and spring rates from 5,904 lb./in. to 44,455 lb./in. Also, these disc springs were designed for thermal movement ranging from 0.011” to 0.46”. The assemblies are fabricated from 304 stainless steel and include Bronzphite® and stainless steel slide plates to lower the coefficient of friction due to lateral movement. Since there is lateral movement, the conventional variable spring would require “internally guided load columns”, however, these units incorporate a “guiding” feature within the spring’s design. They have an installed height of 10-1/2″ – 26”. Each assembly underwent load testing and other NDE and visual inspection by our QC department before shipment. Applications such as Skid Mounted Process Equipment, Pump and Control Skids, Skid Plants, and other types of Skid Packages where space is extremely limited are ideal applications for Compact Springs.

C4000 through C4300 Pre-Insulated Positive Pipe Anchor

How to install this anchor on a pipe?
Does it need to be welded to pipe?

Installation Steps

Installation instructions c4000 3

  1. Center the base weldment assembly (bottom strap with shop welded outer thrust plates) under the applicable support location on the pipe section as shown.
  2. Insert the lower half shield (structural insulation material and sheet metal jacket) between the outer thrust plates and under the pipe as shown.
  3. Place the upper half shield (structural insulation material and sheet metal jacket) over the pipe and lower half shield installed in Step 2 as shown.
  4. Assemble top strap weldment assembly.
    • Top strap with shop welded outer thrust plates over the upper half shield and install the bolts through the clamp ears with nuts on top.
    • Apply the torque on the bolts, select torque value that correspond with the pipe size and model designation of the unit shown on Table 1 below. During tightening, it is recommended that the nut is turned rather than the bolt head and that the bolts be cross-torqued until the required torque has been achieved to obtain an even pressure on the structural insulation.
    • Ensure that the bolts are properly cross-torqued. by checking the spacing “B” between the ears to be approximately the same.
  5. Locate and position factory supplied inner thrust plates (two on each side of the assembly) on the pipe. Locate and position the inner thrust plates on the pipe. When properly positioned weld them to the pipe shown (see Table 1 for the weld size.)
  6. Weld base of anchor assembly to support member as shown. Select “W” (Weld Size) that correspond with the pipe size and model designation of the unit.

Installation instructions c4000 2

Inner Thrust Plate Detail

Note:
In order to act properly as designed, it is important that there is a zero clearance between the inner thrust plates and structural insert. It is recommended that the inner thrust plates be clamped tight against the structural insert before welding and remained clamped until the weld has completely cooled off to avoid or minimize shrinkage and/or distortion due to welding. If there is axial clearance, cut galvanized sheet metal shims to the same outline as the inner thrust plates and install them to reduce this clearance to zero.

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.

Big Ton Spring Supports with Stainless Steel Rollers

Big Ton Springs Designed with Stainless Steel Rollers for a Chemical Plant

PT&P custom-designed big ton spring supports with stainless steel rollers for a chemical plant in Brazil. The frame is fabricated from carbon steel and the shim plates are 2205 duplex stainless steel. The design specified that these big tons are placed in a large “oil pan” that was fabricated from AR400 steel. AR400 steel is abrasion resistant and has a minimum hardness of 360 on the Brinell scale and a nominal hardness of 400. The stainless steel rollers are designed to fit inside the “oil pan” and the big tons are placed on top of the rollers. Oil is then placed inside the pan providing continuous lubrication for the assembly while accommodating the axial or lateral movement of the structure. These big ton spring assemblies include special coils and neoprene drip shields to protect the coils and oil in the pan from debris. The big tons are 26-1/2″ x 33″ x 26-1/2″ with a movement of 0.499″ down and a spring rate of 13,450 lb./in. They are designed for an operating load up to 78,318 lb. and underwent load testing prior to shipment. PT&P, along with our team of engineers and designers, specializes in making the impossible, possible. Over the years, there are many instances where our clients have come to us with unique and unusual applications requiring a product not yet developed or requiring the modification of an existing product.

Variable Springs for a High-Temperature Furnace Application

PT&P Custom Designed Furnace Spring Support Cans For Chemical Plant
PT&P custom-designed and fabricated variable spring supports for a furnace application at a chemical plant in California. The furnace cans are manufactured from carbon steel and painted with red oxide primer because they are exposed to high temperatures where hot-dipped galvanizing is not feasible. The springs are designed for an operating load of 1,261 lb., with movement of 9″ and dimensions of 6″ x 52″ in length. Load tests were performed prior to a 12-14 week shipment.

Within a Reformer, heat-resistant cast alloy tubes are used to produce hydrogen during the process of desulfurization in refining plants, ammonia, methanol, and fertilizer plants. These catalyst tubes (also called reformer tubes) are periodically changed within the units after years of operating under high pressure and temperatures. The new or replacement tubes are manufactured from alloy material that can be lighter or heavier than the previous tubes installed. As a result of this weight change, new furnace springs may also need to be replaced.

Most recently we completed a project for a key client for the largest refinery in Central America with a specialized design using our nano-constant, the world’s smallest constant spring hanger. It supports 765 pounds of load and 7″ of travel in a 0.89 cubic foot envelope (7″ x 10″ x 22″). This particular furnace application required very stringent requirements of load deviation of less than 3% and all supports were made from stainless steel to meet furnace requirements. So, for these particular units, no coating was required since they were manufactured from stainless steel. In order to accomplish this special requirement, our engineering team designed and manufactured a new constant load test machine in-house.

We have manufactured various types of furnace springs and constants for a variety of EPC firms over the past few decades. Our experience and knowledge of the different designs and configurations have helped us to become one of the leading manufacturers of springs and pipe supports for furnace applications.

Constant Supports Custom-Designed for an Ethane Cracker

Constant Spring Supports Custom-Designed with Brush Strip on Horizontal Travelers for an Ethane Cracker

These constant spring supports for an ethane cracker for one of our largest and oldest customers who we worked with almost daily for years. As a matter of fact, a majority of the hangers in this plant are supplied by PT&P dating back to 1971. Today, the new cracker project was designed to take advantage of cheap shale-derived ethane feedstock.

The constant supports were supplied with horizontal travelers with a special “brush strip” help limit the entry of foreign objects. The constants are designed to support an 8” diameter pipeline leading into a furnace. Each spring coil is neoprene coated and the spring can housing is hot-dipped galvanized to protect against corrosion. This type of rigid spring hanger uses a coil or series of coils to accommodate pipe movement throughout the piping system. These particular constant assemblies are designed for horizontal movements ranging from 1” to 6.6” and loads up to 1320 lb. We can customize any material, finish, dimension, load, load adjustment, travel, and travel stops, as well as provide sensors for remote monitoring.

This project was unique in design and testing requirements requested by the client and their customer. Every constant support we build is load-tested by our quality and production teams. In some cases, the customer will ask to witness the testing of a single unit which we do on a regular basis. However, for this project, every constant spring was witness tested with the client’s inspection and engineering teams located at our manufacturing facility utilizing our custom in-house designed test machine.
