- #9 PT&P manufactures a variety of pipe supports and pipe hangers. Pipe system designers must calculate the pull of gravity and for movement due to thermal expansion. Engineered Spring Supports are devices which are cost effective and structurally sound in solving certain pipe support issues. Variables use coiled springs to support a load and movement. The resistance of the coil to a load changes during compression, which is why these devices are called "variables". Big Ton springs are designed primarily for the petrochemical industry where stability and heavy loads are present. Constant Spring Supports are principally used to support pipes and equipment subjected to vertical movement due to thermal expansion at locations where transfer of stress to other supports or equipment can be critical. The maximum recommended variation according to MSS standard from the operating load is 25% for variable spring hangers. If the variation exceeds 25%, a constant support hanger should be used.
- #10 PT&P offers 7 types of variables , meaning seven different physical connections to the supporting structure. Hangers are suspended from structural members while base supports (type-F) rest on a supporting surface. Shown here are just a few of the types offered. Top-Left : F-type variable spring supports , which are designed to support piping from below, directly from the floor or supporting steel. Adjustment is made by inserting a bar into holes in the load column and turning the load column as a jack screw. The base plate is bolted to the case and has four holes for fastening. Top-Right : Spring hangers with 3-bolt clamps. (*I want to point out that PT&P ships the complete assembly, which allows for easier field installation and assists our quality control department in quickly verifying the product for customer service.) Bottom-Left : B-type variable spring with external travel stops. Bottom-Right : G-type variable springs where the spring support assembly is formed by welding two standard spring assemblies to the ends of a pair of channels.
- #11 “ Big Ton” is the name PT&P uses for a special type of variable spring support. Many of these supports have been in service for more than 20 years. A typical big ton will have a rectangular array of coil springs supporting a pressure plate which in turn support a top load flange. - This type of support is used where 2 important characteristics in spring supports are necessary: 1.) Extremely stable : Base supports springs of this design are frequently used under horizontal pressure vessel saddle supports in combination with slide plates or roller supports. Our Big Ton design lends itself ideally to this support situation. Type-F design is sufficient where there is a minimal amount of lateral movement, but where the combination of heavy loads and thermal expansion are required, big ton industrial springs should be your choice. 2.) Heavy Loads : The big tons’ multi-spring design lends itself to supporting very high loads. Loads up to 200,000 lb. can be handled with no problems. Note: division & centering plates divide 2 coils stacked on top of each other and the little guides in side that holds spring in place Top-Left : 90,000 lb. load, A-36 carbon steel big ton spring . Top-Right : 8' long big ton spring assembly fabricated from carbon steel with a painted finish. This big ton includes PTFE, 25% glass filled slide plates already welded to the top of the load flange, which allows for immediate installation in the field. Bottom-Left : A516 Grade 70N carbon steel big ton springs with PTFE, 25% glass filled slide plates on load flange. (79,000 lb.) Bottom-Middle : 63" x 63" big ton springs custom designed from carbon steel with a hot-dipped galvanized finish and a stainless steel slide plate. Bottom-Right : Big ton springs with polished A-304 stainless steel slide plates.
- #12 As mentioned earlier, shipping complete assemblies helps with ease of installation in the field. - The plant supervisor called us in a panic because he could not find the big tons at the site. - The supervisor searched and searched for disassembled parts for a spring, all the while stressing about assembling it before installing it. - We sent a field service technician out to assist, and he found the big ton was already installed. - The supervisor was shocked, he said, “It never crossed my mind, that it was already installed, We are not used to complete assemblies arriving ready to go.”
- #13 Left Picture : C-Type Vertical Constant Top-Right : A-36 carbon steel, 200 U-type upthrust constant for a geothermal plant. - Frame Dimensions: W 40" x H 75" x L 142". - Constant load of 9888 lb. to 10,239 lb. Design Travel: 46". - Utilizes rollers and PTFE, 25% glass filled slide plates to reduce the friction resulting from axial movements. - Standard load and travel testing was conducted prior to shipment. (http://www.pipingtech.com/news/arc_pw_2003/engps2003_05.htm) Bottom-Right : A-36 carbon steel, 200 C-type constants for a steam plant. Load Range: 17,800 lb. to 25,600 lb. - Downward travel ranging between 12 1/2" and 16" Diameter of spring coil housing is 21". - Design includes a universal locking device capable of locking the hanger rod at any desired position. - It also includes lifting lugs that aid in installing the constant in the field. - Standard load and travel testing was performed before shipment. (http://www.pipingtech.com/news/arc_pw_2008/engps2008_04.htm)
- #14 Big Ton Upthrust Constants designed for a global engineering & construction company The customer needed a support for a vessel, but had very limited space available for the support. Big Ton T Upthrust Constants Total Travel: 5" Design Load: 75,000 lb. and 67,464 lb. Total Height: 16.5" Big Ton D Upthrust Constants Total Travel: 4" Design Load: 50,022 lb. Total Height: 26"
- #15 This is a birds-eye view of some U-Type upthrust constants installed in the field Duct work will be installed on top of the constants
- #16 Shock Control, Restraint and Support Devices Sway Braces use spring coils and are recommended for controlling vibration, absorbing shock loadings; guiding or restraining the movement of pipe resulting from thermal expansion; bracing a pipe line against sway. Standard pipe sizes range from 2" to 24". Sway Struts are rigid supports used to restrain movement of piping in one direction while providing for movement due to thermal expansion or contraction in another direction. Hydraulic and Mechanical Snubbers are passive restraints using either fluid or mechanical means to lock or restrain the equipment in place. They are used primarily when the piping load is subject to abrupt conditions, such as movement from seismic or water hammer situations.
- #17 Left : 126" long carbon steel sway braces - Utilize integral piston assembly with guide to eliminate any buckling and/or misalignment during extension and compression - These have 10 ½" of travel and a 1500 lb. load capacity - Combination of standard spring coils is used to achieve required spring rate of 150 lb./in. hydraulic ram test was performed prior to shipping these items Top-Right : Sway braces used to stabilize tall stacks for a Coker Plant. - Deflection capability of up to plus or minus 9" in all directions and 8000 lb. load capacity - Five springs in tandem prevent binding during operation and are necessary due to extreme length - Precision machined pivoting ball joints positioned at each end allow for freedom of movement in any unpredictable direction Bottom-Right : Travel test being performed on sway brace for a client, this sway brace is designed for 14" of travel.

- #26 DO NOT, DO NOT, DO NOT….. DO NOT SAY TEFLON….!!!!! Slide plates are a very cost-effective way to allow for movement of mechanical systems for very high temperatures and cryogenic temperatures as well. They are also suited for both high and low loads. We supply slide plates for a variety of applications including support of piping, heavy equipments such as pressure vessels, and structural members. The plates provide a surface with a low coefficient of friction which can be attached to a supporting structure. This combination provides support while simultaneously allowing an object to move or slide freely along the supporting structure. Shown here are the five main materials used: PTFE, 25% Glass Filled, Bronzphite®, Graphite, Marinite and Stainless Steel - Sandwich Concept: Most designers use the “sandwich” concept, which is simply two slide plates one on top of another. Each slide plate is composed of two components: 1) metal backing plate, which is the “bun” of the sandwich and 2.) a low coefficient friction material which is bonded to the metal backing plate - The illustration on the bottom-right shows a slide plate that is welded on top of one steel beam supporting another steal beam. When the top beam moves, it slides across the surface of the plate without contacting the supporting beam. The top half of the “sandwich” is bonded to the sliding beam, bottom half of “sandwich” to the supporting beam. DO NOT, DO NOT, DO NOT….. DO NOT SAY TEFLON….!!!!! If you need it…. NOTE: PTFE, 25% Glass Filled: PTFE is the abbreviation for Polytetrafluoroethylene. PT&P uses PTFE filled with 25% Glass Fibers (by weight). Fillers improve the strength and durability. *We also have a slide plates Webinar recording available on our website
- #27 Our U.S. Bellows division provides a wide variety of expansion joint products and services. The general categories supplied can be described by the materials used and the type of movement provided. We also provide Emergency Replacement Services for time constrained issues that may arise. Pictured here are the different types of thin wall metallic expansion joints: - Single bellows expansion joints are the most economical. Can absorb small amounts of axial, lateral & angular movements, & can deflect in any direction. - Hinged joints can bend in a single plane & designed to accept the full pressure thrust. - A gimbal joint is similar to hinged, except that instead of being limited to deflection in only one plane, it can accept bending or angulation in any plane. - Our tied universal expansion joint consists of two bellows separated by a pipe section or spool. The primary purpose of this arrangement is to have a unit which will accept large amounts of lateral deflection. - On the second row, you see an elbow pressure balanced joint which retains & balances the pressure thrust so main anchoring of the pipe or adjacent equipment is not required, & forces & movements on attachment flanges of delicate equipment, such as turbines, are kept to acceptably low levels. - Next, you see an inline pressure balanced joint . When axial deflections exist, & anchoring is impractical for structural or economic reasons, such as high in the air or short straight pipe runs between two large vessels, this type of expansion joint is a powerful solution to a difficult design problem. - Externally pressurized joints are used when large amounts of axial deflection are required in piping systems of relatively high pressure. - A toroidal convolution consists of a circular tube (or totus) wrapped around weld ends or pipe ends having a gap at the I.D. to permit axial stroke. Most toroidal bellows are hydraulically formed which requires high pressure. Others are free formed, similar to blowing up a balloon. More accurate convolution shapes may be formed into toroidal dye cavities. Since this forming pressure is high, pressure resistance is also high.
- #28 Shown here are additional expansion joint categories starting with the thick wall… - This type of expansion joint is cost-effective for large-diameter piping systems which operate at low pressure. Convolutions for our thick wall joints are fabricated by shaping two washer-shaped metal pieces. A single convolution is formed by welding the outside circumference. - Shown next is a slip-type , which is commonly used when the primary problem is large axial movement. - Next is a rectangular metal expansion joint with rounded corners. Since there are no standard duct sizes, and due to the wide range of pressure and temperature combinations, each rectangular metal expansion joint is custom-engineered to provide the most economical design that will not sacrifice the integrity of the joint or the system in which it is installed. - Our fabric joints are often used in ducts which carry hot gases at low pressures. - Next to it, you see a neoprene fabric joint , which are mostly used in low temperature water applications. - Lastly, is the clam shell bellows which is a thin wall metallic expansion joint.

- #37 3, 36 " Diameter single gimbal expansion joints for a large petrochemical company in California. These joints are designed for a pressure of 750 PSIG at 275 ° F. The design pressure thrust is approximately 1,000,000 lb. and the hydro-test pressure thrust is approximately 1,500,000 lb. Fabricated from Inconel 625 material, these expansion joints are equipped with testing ports to detect leakage in between the two plies. The gimbal ring, hinges, standoff, and pins have all been designed to withstand the design and hydro-test pressure thrust force. The total assembled weight of each expansion joint is 14,560 lb. Gimbal expansion joints allow for restrained angular movement of attached piping in two planes. Expansion joints, in general, allow for axial, lateral, angular and Torsional movement in piping systems. FEA was used to design this gimbal expansion joint assembly and structural FEA was performed to ensure the product is structurally sound. Determining the thermal profile helps to prevent polythionic corrosion of the bellows. http://www.usbellows.com/news/pr01.htm
