Universal Expansion Joints Custom-Designed for a Hot Air Blower

July 12, 2021

Universal Expansion Joints Custom-Designed for a Hot Air Blower

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.

U.S. Bellows Custom-Designed Tied Universal Expansion Joints for Service at a Chemical Plant

February 9, 2021

U.S. Bellows Custom-Designed Tied Universal Expansion Joints for Service at a Chemical Plant.

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.

Single Flanged Expansion Joints for a Leading Manufacturer & Designer of Transformers & Power Supplies for an Industrial Applications Company

August 24, 2020

U.s. bellows custom designed single fanged expansion joints for a leading manufacturer & designer of transformers & power supplies for an industrial applications company

Type: Single Flanged Expansion Joint
Size: 5″ Length | 6″ ID | 11″ O.D.
Material: ASTM A240-316 Stainless Steel
Design 200°F | 150 psig | 7,942 lb/in. Lateral Spring Rate
0.625 ” Axial Travel | 803 lb/in. Axial Spring Rate
0.125″ Lateral Offset | 225 psig Test Pressure
Testing: 100% Dye-Penetrant | Air, Soap, & Bubble

The single expansion joint type is simply a bellows element with end connections. It is the least expensive type but requires that the piping be controlled as to the direction of the movements required of the unit. This type of expansion joint should not be expected to control the movement of the pipe. If the piping analysis shows that the expansion joint must accept axial compression, then the piping must be guided and constrained in other locations so that only that axial movement will occur. The flanges and bellows are fabricated from ASTM A240-316 stainless steel. The units are 6″ in diameter, 5″ long, and have an 11″ outside diameter. Design conditions are: design pressure = 150 psig, test pressure = 225 psig, design temp. = 200°F, axial travel = 0.625″ compression, axial spring rate = 803 lb/in., lateral offset = 0.125″, and lateral spring rate = 7,942 lb/in. *Designed in accordance with the Standards of the Expansion Joint Manufacturers Association, 10th E, and welding per ASME Boiler and Pressure Vessel Code Section IX.
