U.S. Bellows custom designed this 26 ft. -10 in. long universal expansion joint with ductwork for a chemical plant. The bellows, ductwork, and flanges were fabricated from 304 stainless steel and the rest of the components from carbon steel. The unit is designed for 48″ diameter piping with an operating temperature of 400°F at 91 psig and 3.3″ of lateral deflection. The expansion joint was completed in 12 weeks and was 100% dye-penetrant, PMI, and hydro-tested before shipment. Chemical plants for which these are typically required process chemicals such as ethylene oxide/glycols, toluene diisocyanate, methylene diphenyl isocyanate, hydrochloric acid, polyether polyols, butanediol, GBL, n-methyl pyrrolidone, tetrahydrofuran, 2-pyrrolidone, PVP/PVPi, specialty amines, aniline, acetylene, surfactants, polytetrahydrofuran, and methylamines. The end products include furniture, automotive antifreeze, foams, carpets, construction, steel pickling, oil well acidizing, biodegradable plastics, lithium-ion battery production, pharmaceuticals, agriculture, gas treatment, water treatment, toothpaste, detergent, spandex fibers, engineered high-performance plastics, and animal feed.
U.S. Bellows has the scale and manufacturing agility to produce expansion joints and ductwork ranging in order size from a small scale of sub-1000 of dollars to upwards of 1M dollar large capital projects. We regularly support overnight lead times and tight project deliverables with evolving project requirements per the client and site needs. Last month, over half of our production capacity, was dedicated to this kind of work. A glimpse into our capabilities is outlined below from some projects we did last year:
– Refurbished 6, 48″-64″ diameter refractory-lined expansion joints for a large Houston refinery during a 45-day turnaround
– Completed a large ducting project for a major chemical facility in Texas with on-time delivery
– In the last 6 months, 40% of our expansion joint jobs have shipped in 2 weeks
We invite you to visit our facility and meet our team to get a first-hand look at our capabilities for your upcoming projects.

These universal expansion joints were custom-designed with guided tie rods, internal liners, and bellows protection covers for a hot air blower. These expansion joints are used in a plant that manufactures tires for cars and light-duty trucks. High Heat is required in the manufacturing process to vulcanize rubber to components made of steel and polyester and to also cure the rubber. The universal expansion joint can allow for large amounts of lateral deflection that can occur in more than one plane. By increasing or decreasing the distance between the two bellows by varying the length of a section of pipe spool, the designer can accommodate for the given amount of lateral deflection. These expansion joints are designed for an operating pressure of 50 psig at 383 degrees F. A total of 18 were supplied with half of the units measuring 40” dia. x 74-7/8” long x 58-1/2” overall outer dia. The rest measure 36” dia. X 60-1/4” long x 53-3/4” overall outer diameter. The bellows, flange, middle pipe, liner, and lugs are fabricated from 316/316L stainless steel. The rods, nuts, and cover are 316 stainless steel. The 40” dia. unit is designed for 0.394” axial compression and the 36” dia. unit is designed for 0.20” axial compression. Both units are designed for 0.394” lateral movement. Each expansion joint was inspected by quality control and hydraulic pressure tested before shipment. We manufacture expansion joints to relieve stress in piping systems whether the thermal movement is axial, lateral, or angular in plants such as Food Processing, Automotive, Hospital Steam Lines, Semiconductors, and other types of Green Energy plants.

Universal expansion joints such as these are used in chemical plants that manufacture petrochemicals (such as ethylene and styrene monomer), polymers, and building products (PVC profiles for windows, doors, and decking). The units range from 26” to 48” in length and 8” to 20” in diameter. The bellows were fabricated from 321 stainless steel, the weld ends, pipe spools, and flanges from 304 stainless steel, and the tie rods and hex nuts from carbon steel. They are designed for temperatures ranging from -150°F to 800°F, operating pressures ranging from 50 to 240 psig, and 0.25” to 2.25” of lateral deflection. The expansion joints were air, soap, and bubble tested, 100% dye-penetrant tested and hydro-tested before shipment. The universal pipe expansion joint consists of two bellows separated by a pipe section or spool. The primary purpose of this arrangement is to have a unit that will accept large amounts of lateral deflection. The amount of lateral deflection they can accept is a function of the amount of angulation each bellows can absorb and the distance between the bellows. For a given bellows element, the amount of lateral deflection capability can be increased or decreased by simply changing the length of the center spool.

U.S. Bellows custom-designed and fabricated universal gimbal expansion joints for 24” diameter crude oil pipelines at a power plant in Canada. The bellows are fabricated from A240 316 stainless steel bellows, the flanges are A105N carbon steel, and the plates are A516 70 carbon steel. The expansion joints are designed for a 10 degrees angular rotation at 285 psig up to 100 degrees F. They are designed for an angular spring rate of 4900 in-lb/dec and vertical offset of 10-1/4”. The units measure 43” x 43” x 110” and 38” x 38” x 79”.
3D Modeling was done so that our engineers can check the “fit-up” to confirm the design, perform stress analysis, or other modeling benefits prior to fabrication. We performed hydro tests, completed NDE reports, and supplied Material Test Reports per the client requirements.
